In the year 2024, the exam underwent a series of reforms, reflecting the evolving needs and expectations of both students and the broader societal landscape.One of the most notable changes was the increased emphasis on practical communication skills.

The essay prompt often revolved around contemporary social, political, or environmental issues, challenging students to not only showcase their language proficiency but also their intellectual engagement with the world around them.For many students, this essay component represented both anexciting opportunity and a daunting challenge.

On the other hand, the pressure to produce a high-quality essay within a limited time frame added an additional layer of complexity to the exam experience.To prepare for this new essay section, students adopted a variety of strategies. Some immersed themselves in reading a wide range of news articles and academic publications, familiarizing themselves with the latest trends and debates in various fields. Others engaged in peer-to-peer writing workshops, honing their ability to provide constructive feedback and refine their own writing skills. The most dedicated students even sought out specialized tutoring or enrolled in extracurricular writing courses to further enhance their essay-writing prowess.As the December CET-4 exam approached, the sense of anticipation and anxiety among students was palpable.

However, when the essay prompt was revealed, a hush fell over the examination hall as students began to carefully craft their responses.The essay topics ranged from discussions on the impact of technological advancements on social interactions to debates on the role of government in addressing environmental challenges. Students were required to not only demonstrate their mastery of the English language but also their ability to analyze complex issues, synthesize information, and present a well-reasoned argument.As the exam progressed, the sound of pen on paper and the occasional rustling of pages filled the air, punctuated by the occasional sigh or murmur of concentration. For many students, the essay section proved to be the most challenging, as they grappled with the need to balance their time, organize their thoughts, and convey their ideas with clarity and precision.Yet, despite the challenges, the December CET-4 exam also presented an opportunity for students to showcase their growth and development. The new format, with its emphasis on practical communication skills and critical thinking, allowed them todemonstrate their adaptability and their ability to rise to the occasion.As the exam drew to a close, students emerged from the testing centers with a mix of emotions.

2 Approach
Our goal is to make a system which can not only interact with a user by accurately recognizing gestures, but which can learn new gestures and update its understanding of gestures it already knows in an online, interactive manner. Our approach is automated generation and iterative training of a set of Hidden
robot learns to perform a task by observing a human teacher. Much e ort is being directed toward the research of systems for gesture/observation-based programming of robot systems. Tung and Kak 1] demonstrate automatic learning of robot tasks through a DataGlove interface. Kang and Ikeuchi 2] developed a system for simple task learning by human demonstration. Voyles 3] developed a system for gesturebased programming via a multi-agent model. One capability which is currently lacking in systems such as these is a mechanism for online teaching of gestures with symbolic meanings. Most gesture recognition systems either require some explicit programming, or in the case of neural-nets, require o ine training of model parameters. Such systems are thus unsuitable for interactive applications where gestures must be taught and then recognized without waiting for an o ine training or programming phase. A teach-by-demonstration system should also be able to learn a new gesture or skill in an online manner and with a very small number of examples. This simpli es the teaching process because it more closely resembles the manner of instruction which we commonly use to train people. In this paper, we present a gesture recognition system which can interactively recognize gestures and learn new gestures online with as few as one or two examples. It is also able to update its model of a gesture iteratively with each example it recognizes.
Markov models which represent human gestures. Using this approach, we have built and tested a system which recognizes letters from the sign language alphabet using a Virtual Technologies `Cyberglove'. The most basic assumption we make about the nature of human gestures are that they are \doubly stochastic" processes. These are Markov processes whose internal state is not directly observable. For each state transition in such a process, the system generates an observable output signal whose value depends on a probability distribution which is xed for each internal state. A model of such a system is called a Hidden Markov Model (HMM). Modelling human gestures as HMMs allows us to deal with the highly stochastic nature of human gesture performance. For computational simplicity, we assume that the the HMMs are `discrete' HMMs. These are HMMs whose observable outputs are members of a nite set of symbols. Before we can use discrete HMMs to model gestures, we must therefore preprocess the raw data from the gesture input device into a sequence of discrete symbols. Gesture recognition is, to a certain extent, a process of data compression, where we input a large amount of raw data and output a signal value that represents the classi cation of the gesture. This compression process is composed of two stages. The greatest data-reduction occurs when the preprocessor converts the large, multichannel stream of data from the gesture input device to the sequence of discrete observable symbols. We reduce about 0.5-1.0 Kbytes of data from the Cyberglove to a sequence of 5-10 observable symbols from a set of 32 and 256 symbols, which is a reduction of about 100:1. Since the online portion of our gesture learning process is limited to the modi cation of the parameters of HMMs, this data-reduction greatly increases the speed and simplicity of the online learning process by focussing the HMM on modelling speci c features of the signal.
Abstract
We have developed a gesture recognition system, based on Hidden Markov Models, which can interactively recognize gestures and perform online learning of new gestures. In addition, it is able to update its model of a gesture iteratively with each example it recognizes. This system has demonstrated reliable recognition of 14 di erent gestures after only one or two examples of each. The system is currently interfaced to a Cyberglove for use in recognition of gestures from the sign language alphabet. The system is being implemented as part of an interactive interface for robot teleoperation and programming by example.
