Ladies and Gentlemen,Good morning/afternoon. It is an honor to stand before you today to discuss a topic that is both fascinating and daunting: the world of cybersecurity and the role of hackers in it. In this digital age, where our lives are intertwined with the internet, the importance of understanding the cybersecurity landscape cannot be overstated. Today, I will delve into the world of hackers, their motivations, the challenges they face, and the future of cybersecurity.Firstly, let us define what a hacker is. A hacker is someone who uses their technical skills to access and manipulate digital systems. While many hackers are motivated by malicious intent, there are also ethical hackers, also known as white-hat hackers, who use their skills to improve security and protect against cyber threats.The world of hackers is diverse, and their motivations can range from curiosity to financial gain. Some hackers are driven by the thrill of breaking into secure systems, while others seek to steal sensitive information, such as credit card details or personal data. However, there are also those who use their skills to identify vulnerabilities in software and alert companies before malicious actors can exploit them.One of the most significant challenges facing hackers is the rapid evolution of technology. As new technologies emerge, so do new vulnerabilities and attack vectors. Hackers must continuously update their knowledge and skills to stay ahead of the curve. This constant learning curve is not only a challenge for individual hackers but also for organizations trying to protect their systems.Another challenge is the complexity of modern digital infrastructures. With the rise of cloud computing, the Internet of Things (IoT), and other interconnected systems, the attack surface has expanded exponentially. This complexity makes it difficult for both hackers and security professionals to identify and protect against threats.Despite these challenges, the role of hackers in cybersecurity is invaluable. Ethical hackers play a crucial role in identifyingvulnerabilities that could be exploited by malicious actors. By conducting penetration testing and vulnerability assessments, they help organizations strengthen their defenses and protect their data.Now, let's discuss the future of cybersecurity. As technology continues to advance, so will the threats. Here are a few trends that we should be aware of:1. Artificial Intelligence (AI): AI is becoming increasingly sophisticated, and it will play a significant role in both offensive and defensive cybersecurity strategies. Hackers will use AI to automatetheir attacks, while security professionals will leverage AI to detect and mitigate threats.2. Cybersecurity as a Service (CSaaS): With the growing complexity of cybersecurity, more organizations will opt for managed security services to protect their digital assets. This shift will create newopportunities for hackers to exploit vulnerabilities in these services.3. Cyber Warfare: As nations become more dependent on digital infrastructures, the risk of cyber warfare will increase. Hackers will likely be used as proxies in geopolitical conflicts, making the landscape even more volatile.In conclusion, the world of hackers is a complex and dynamic one. While we must remain vigilant against malicious actors, we should also recognize the importance of ethical hackers in improving our cybersecurity defenses. As we navigate the cybersecurity landscape, itis essential to stay informed, adapt to new technologies, and collaborate across the industry to protect our digital lives.Thank you for your attention. I invite you to join the conversation and contribute to the ongoing effort to secure our digital future.。

神经网络概述外文翻译文献

神经网络概述外文翻译文献(文档含中英文对照即英文原文和中文翻译)原文:Neural Network Introduction1.ObjectivesAs you read these words you are using a complex biological neural network. You have a highly interconnected set of some 1011neurons to facilitate your reading, breathing, motion and thinking. Each of your biological neurons,a rich assembly of tissue and chemistry, has the complexity, if not the speed, of a microprocessor. Some of your neural structure was with you at birth. Other parts have been established by experience.Scientists have only just begun to understand how biological neural networks operate. It is generally understood that all biological neural functions, including memory, are stored in the neurons and in the connections between them. Learning is viewed as the establishment of new connections between neurons or the modification of existing connections.This leads to the following question: Although we have only a rudimentary understanding of biological neural networks, is it possible to construct a small set of simple artificial “neurons” and perhaps train them to serve a useful function? The answer is “yes.”This book, then, is about artificial neural networks.The neurons that we consider here are not biological. They are extremely simple abstractions of biological neurons, realized as elements in a program or perhaps as circuits made of silicon. Networks of these artificial neurons do not have a fraction of the power of the human brain, but they can be trained to perform useful functions. This book is about such neurons, the networks that contain them and their training.2.HistoryThe history of artificial neural networks is filled with colorful, creative individuals from many different fields, many of whom struggled for decades todevelop concepts that we now take for granted. This history has been documented by various authors. One particularly interesting book is Neurocomputing: Foundations of Research by John Anderson and Edward Rosenfeld. They have collected and edited a set of some 43 papers of special historical interest. Each paper is preceded by an introduction that puts the paper in historical perspective.Histories of some of the main neural network contributors are included at the beginning of various chapters throughout this text and will not be repeated here. However, it seems appropriate to give a brief overview, a sample of the major developments.At least two ingredients are necessary for the advancement of a technology: concept and implementation. First, one must have a concept, a way of thinking about a topic, some view of it that gives clarity not there before. This may involve a simple idea, or it may be more specific and include a mathematical description. To illustrate this point, consider the history of the heart. It was thought to be, at various times, the center of the soul or a source of heat. In the 17th century medical practitioners finally began to view the heart as a pump, and they designed experiments to study its pumping action. These experiments revolutionized our view of the circulatory system. Without the pump concept, an understanding of the heart was out of grasp.Concepts and their accompanying mathematics are not sufficient for a technology to mature unless there is some way to implement the system. For instance, the mathematics necessary for the reconstruction of images from computer-aided topography (CAT) scans was known many years before the availability of high-speed computers and efficient algorithms finally made it practical to implement a useful CAT system.The history of neural networks has progressed through both conceptual innovations and implementation developments. These advancements, however, seem to have occurred in fits and starts rather than by steady evolution.Some of the background work for the field of neural networks occurred in the late 19th and early 20th centuries. This consisted primarily of interdisciplinary work in physics, psychology and neurophysiology by such scientists as Hermann vonHelmholtz, Ernst Much and Ivan Pavlov. This early work emphasized general theories of learning, vision, conditioning, etc.,and did not include specific mathematical models of neuron operation.The modern view of neural networks began in the 1940s with the work of Warren McCulloch and Walter Pitts [McPi43], who showed that networks of artificial neurons could, in principle, compute any arithmetic or logical function. Their work is often acknowledged as the origin of theneural network field.McCulloch and Pitts were followed by Donald Hebb [Hebb49], who proposed that classical conditioning (as discovered by Pavlov) is present because of the properties of individual neurons. He proposed a mechanism for learning in biological neurons.The first practical application of artificial neural networks came in the late 1950s, with the invention of the perception network and associated learning rule by Frank Rosenblatt [Rose58]. Rosenblatt and his colleagues built a perception network and demonstrated its ability to perform pattern recognition. This early success generated a great deal of interest in neural network research. Unfortunately, it was later shown that the basic perception network could solve only a limited class of problems. (See Chapter 4 for more on Rosenblatt and the perception learning rule.)At about the same time, Bernard Widrow and Ted Hoff [WiHo60] introduced a new learning algorithm and used it to train adaptive linear neural networks, which were similar in structure and capability to Rosenblatt’s perception. The Widrow Hoff learning rule is still in use today. (See Chapter 10 for more on Widrow-Hoff learning.) Unfortunately, both Rosenblatt's and Widrow's networks suffered from the same inherent limitations, which were widely publicized in a book by Marvin Minsky and Seymour Papert [MiPa69]. Rosenblatt and Widrow wereaware of these limitations and proposed new networks that would overcome them. However, they were not able to successfully modify their learning algorithms to train the more complex networks.Many people, influenced by Minsky and Papert, believed that further research onneural networks was a dead end. This, combined with the fact that there were no powerful digital computers on which to experiment,caused many researchers to leave the field. For a decade neural network research was largely suspended. Some important work, however, did continue during the 1970s. In 1972 Teuvo Kohonen [Koho72] and James Anderson [Ande72] independently and separately developed new neural networks that could act as memories. Stephen Grossberg [Gros76] was also very active during this period in the investigation of self-organizing networks.Interest in neural networks had faltered during the late 1960s because of the lack of new ideas and powerful computers with which to experiment. During the 1980s both of these impediments were overcome, and researchin neural networks increased dramatically. New personal computers and workstations, which rapidly grew in capability, became widely available. In addition, important new concepts were introduced.Two new concepts were most responsible for the rebirth of neural net works. The first was the use of statistical mechanics to explain the operation of a certain class of recurrent network, which could be used as an associative memory. This was described in a seminal paper by physicist John Hopfield [Hopf82].The second key development of the 1980s was the backpropagation algo rithm for training multilayer perceptron networks, which was discovered independently by several different researchers. The most influential publication of the backpropagation algorithm was by David Rumelhart and James McClelland [RuMc86]. This algorithm was the answer to the criticisms Minsky and Papert had made in the 1960s. (See Chapters 11 and 12 for a development of the backpropagation algorithm.) These new developments reinvigorated the field of neural networks. In the last ten years, thousands of papers have been written, and neural networks have found many applications. The field is buzzing with new theoretical and practical work. As noted below, it is not clear where all of this will lead US.The brief historical account given above is not intended to identify all of the major contributors, but is simply to give the reader some feel for how knowledge inthe neural network field has progressed. As one might note, the progress has not always been "slow but sure." There have been periods of dramatic progress and periods when relatively little has been accomplished.Many of the advances in neural networks have had to do with new concepts, such as innovative architectures and training. Just as important has been the availability of powerful new computers on which to test these new concepts.Well, so much for the history of neural networks to this date. The real question is, "What will happen in the next ten to twenty years?" Will neural networks take a permanent place as a mathematical/engineering tool, or will they fade away as have so many promising technologies? At present, the answer seems to be that neural networks will not only have their day but will have a permanent place, not as a solution to every problem, but as a tool to be used in appropriate situations. In addition, remember that we still know very little about how the brain works. The most important advances in neural networks almost certainly lie in the future.Although it is difficult to predict the future success of neural networks, the large number and wide variety of applications of this new technology are very encouraging. The next section describes some of these applications.3.ApplicationsA recent newspaper article described the use of neural networks in literature research by Aston University. It stated that "the network can be taught to recognize individual writing styles, and the researchers used it to compare works attributed to Shakespeare and his contemporaries." A popular science television program recently documented the use of neural networks by an Italian research institute to test the purity of olive oil. These examples are indicative of the broad range of applications that can be found for neural networks. The applications are expanding because neural networks are good at solving problems, not just in engineering, science and mathematics, but m medicine, business, finance and literature as well. Their application to a wide variety of problems in many fields makes them very attractive. Also, faster computers and faster algorithms have made it possible to use neuralnetworks to solve complex industrial problems that formerly required too much computation.The following note and Table of Neural Network Applications are reproduced here from the Neural Network Toolbox for MATLAB with the permission of the Math Works, Inc.The 1988 DARPA Neural Network Study [DARP88] lists various neural network applications, beginning with the adaptive channel equalizer in about 1984. This device, which is an outstanding commercial success, is a single-neuron network used in long distance telephone systems to stabilize voice signals. The DARPA report goes on to list other commercial applications, including a small word recognizer, a process monitor, a sonar classifier and a risk analysis system.Neural networks have been applied in many fields since the DARPA report was written. A list of some applications mentioned in the literature follows.AerospaceHigh performance aircraft autopilots, flight path simulations, aircraft control systems, autopilot enhancements, aircraft component simulations, aircraft component fault detectorsAutomotiveAutomobile automatic guidance systems, warranty activity analyzersBankingCheck and other document readers, credit application evaluatorsDefenseWeapon steering, target tracking, object discrimination, facial recognition, new kinds of sensors, sonar, radar and image signal processing including data compression, feature extraction and noise suppression, signal/image identification ElectronicsCode sequence prediction, integrated circuit chip layout, process control, chip failure analysis, machine vision, voice synthesis, nonlinear modeling EntertainmentAnimation, special effects, market forecastingFinancialReal estate appraisal, loan advisor, mortgage screening, corporate bond rating, credit line use analysis, portfolio trading program, corporate financial analysis, currency price predictionInsurancePolicy application evaluation, product optimizationManufacturingManufacturing process control, product design and analysis, process and machine diagnosis, real-time particle identification, visual quality inspection systems, beer testing, welding quality analysis, paper quality prediction, computer chip quality analysis, analysis of grinding operations, chemical product design analysis, machine maintenance analysis, project bidding, planning and management, dynamic modeling of chemical process systemsMedicalBreast cancer cell analysis, EEG and ECG analysis, prosthesis design, optimization of transplant times, hospital expense reduction, hospital quality improvement, emergency room test advisement0il and GasExplorationRoboticsTrajectory control, forklift robot, manipulator controllers, vision systems SpeechSpeech recognition, speech compression, vowel classification, text to speech synthesisSecuritiesMarket analysis, automatic bond rating, stock trading advisory systems TelecommunicationsImage and data compression, automated information services,real-time translation of spoken language, customer payment processing systemsTransportationTruck brake diagnosis systems, vehicle scheduling, routing systems ConclusionThe number of neural network applications, the money that has been invested in neural network software and hardware, and the depth and breadth of interest in these devices have been growing rapidly.4.Biological InspirationThe artificial neural networks discussed in this text are only remotely related to their biological counterparts. In this section we will briefly describe those characteristics of brain function that have inspired the development of artificial neural networks.The brain consists of a large number (approximately 1011) of highly connected elements (approximately 104 connections per element) called neurons. For our purposes these neurons have three principal components: the dendrites, the cell body and the axon. The dendrites are tree-like receptive networks of nerve fibers that carry electrical signals into the cell body. The cell body effectively sums and thresholds these incoming signals. The axon is a single long fiber that carries the signal from the cell body out to other neurons. The point of contact between an axon of one cell and a dendrite of another cell is called a synapse. It is the arrangement of neurons and the strengths of the individual synapses, determined by a complex chemical process, that establishes the function of the neural network. Figure 6.1 is a simplified schematic diagram of two biological neurons.Figure 6.1 Schematic Drawing of Biological NeuronsSome of the neural structure is defined at birth. Other parts are developed through learning, as new connections are made and others waste away. This development is most noticeable in the early stages of life. For example, it has been shown that if a young cat is denied use of one eye during a critical window of time, it will never develop normal vision in that eye.Neural structures continue to change throughout life. These later changes tend to consist mainly of strengthening or weakening of synaptic junctions. For instance, it is believed that new memories are formed by modification of these synaptic strengths. Thus, the process of learning a new friend's face consists of altering various synapses.Artificial neural networks do not approach the complexity of the brain. There are, however, two key similarities between biological and artificial neural networks. First, the building blocks of both networks are simple computational devices (although artificial neurons are much simpler than biological neurons) that are highly interconnected. Second, the connections between neurons determine the function of the network. The primary objective of this book will be to determine the appropriate connections to solve particular problems.It is worth noting that even though biological neurons are very slow whencompared to electrical circuits, the brain is able to perform many tasks much faster than any conventional computer. This is in part because of the massively parallel structure of biological neural networks; all of the neurons are operating at the same time. Artificial neural networks share this parallel structure. Even though most artificial neural networks are currently implemented on conventional digital computers, their parallel structure makes them ideally suited to implementation using VLSI, optical devices and parallel processors.In the following chapter we will introduce our basic artificial neuron and will explain how we can combine such neurons to form networks. This will provide a background for Chapter 3, where we take our first look at neural networks in action.译文:神经网络概述1.目的当你现在看这本书的时候,就正在使用一个复杂的生物神经网络。

As we all know, hacking has been a topic of great interest and controversy in recent years. In this speech, I will delve into the world of hackers, exploring their motivations, skills, and the ethical dilemmas they face.Firstly, let's define what a hacker is. A hacker is someone who usestheir technical skills to gain unauthorized access to computer systemsor networks. While some hackers have malicious intentions, others use their skills for legitimate purposes, such as improving security or discovering vulnerabilities. In this speech, I will focus on both types of hackers.Now, let's talk about the motivations behind hacking. For some hackers, the allure of hacking lies in the thrill of breaking into secure systems and the satisfaction of outsmarting security measures. They may seek recognition, power, or simply the challenge. On the other hand, ethical hackers, also known as white-hat hackers, are driven by a desire to make the internet a safer place. They use their skills to identify and report vulnerabilities to organizations, helping them strengthen their defenses against cyber threats.Hacking skills are crucial in the world of cyber security. A hacker must possess a strong understanding of computer systems, networking, programming, and cryptography. They must be able to think critically and creatively to bypass security measures and uncover hiddenvulnerabilities. In addition, hackers must stay up-to-date with thelatest technologies and threats, as the cyber landscape is constantly evolving.However, the world of hacking is not without its ethical dilemmas. Many hackers face the temptation to use their skills for malicious purposes. This can lead to serious consequences, including financial loss,identity theft, and even loss of life. Ethical hackers must navigate these dilemmas and make responsible decisions when using their skills.In order to become an ethical hacker, one must undergo rigorous training and certification. Organizations such as the EC-Council offercertifications such as the Certified Ethical Hacker (CEH) that help individuals develop the necessary skills and knowledge to becomeeffective white-hat hackers. By pursuing these certifications,individuals can contribute to the fight against cybercrime and help protect the digital world.Now, let's discuss the impact of hacking on society. On one hand,hacking can cause significant harm, as we have seen in numerous high-profile cyber attacks. These attacks can lead to financial loss, data breaches, and even physical damage. On the other hand, hacking can also have positive impacts. For example, white-hat hackers can help organizations improve their security, protect their customers' data, and prevent cyber attacks from causing further damage.In conclusion, the world of hackers is a complex and fascinating subject. Hacking can be used for both good and evil, and it is up to us to make responsible decisions when using our technical skills. As we move forward, it is crucial that we continue to educate and train ethical hackers to help protect the digital world from cyber threats.Thank you for your attention, and I hope that this speech has provided you with a better understanding of the world of hackers.。

大学生的网络安全英文演讲稿范文

大学生的网络安全英文演讲稿范文Good morning, ladies and gentlemen,Today, I would like to talk to you about the importance of network security for college students. With the rapid development of technology, the Internet has become an indispensable part of our daily lives, especially for college students. We use the Internet for communication, research, entertainment, and even for our studies. However, with the increasing use of the Internet, network security has become a major concern for college students.As college students, we often use public Wi-Fi networks to access the Internet. While public Wi-Fi networks are convenient, they are also prone to security risks. Hackers can easily intercept the data transmitted over public Wi-Fi networks and steal our personal information, such as usernames, passwords, and credit card numbers. Therefore, itis important for college students to be aware of the security risks associated with public Wi-Fi networks and take necessary precautions to protect their personal information.In addition to public Wi-Fi networks, college students also need to be vigilant about phishing scams and malware. Phishing scams are fraudulent attempts to obtain sensitive information, such as passwords and credit card numbers, by disguising as a trustworthy entity in electronic communication. Malware, on the other hand, is malicious software that is designed to infiltrate and damage a computer system. Both phishing scams and malware pose a serious threat to the security of college students' personal information and should be taken seriously.To protect ourselves from these security risks, college students should take the following precautions:1. Use strong and unique passwords for all online accounts.2. Enable two-factor authentication whenever possible.3. Avoid clicking on suspicious links or downloadingfiles from unknown sources.4. Install and regularly update antivirus and anti-malware software on our devices.5. Use a virtual private network (VPN) when accessing the Internet on public Wi-Fi networks.6. Regularly monitor our financial accounts for any unauthorized transactions.In conclusion, network security is a critical issue for college students. By being aware of the security risks and taking necessary precautions, we can protect our personal information and safeguard our online privacy. As college students, we should take network security seriously and make it a priority in our daily lives.Thank you for your attention.。
