Learning new compositions from given ones

Learning New Compositions from Given OnesJi DonghongDepartment of Computer ScienceTsinghua UniversityBeijing, 100084, P. R. ChinaEmail: jdh@He JunDepartment of Computer ScienceHerbin Institute of TechnologyEmail: hj@Huang ChangningDepartment of Computer ScienceTsinghua UniversityBeijing, 100084, P. R. ChinaEmail: hcn@Abstract:In this paper, we study the problem of learning new compositions of words from given ones with a specific syntactic structure, e.g., A-N or V-N structures. We first cluster words according to the given compositions, then construct a cluster-based compositional frame for each word cluster, which contains both new and given compositions relevant with the words in the cluster. In contrast to other methods, we don’t pre-define the number of clusters, and formalize the problem of clustering words as a non-linear optimization one, in which we specify the environments of words based on word clusters to be determined, rather than their neighboring words. To solve the problem, we make use of a kind of cooperative evolution strategy to design an evolutionary algorithm.Key words: word compositions, evolutionary learning, clustering, natural language processing.1. IntroductionWord compositions have long been a concern in lexicography(Benson et al. 1986; Miller et al. 1995), and now as a specific kind of lexical knowledge, it has been shown that they have an important role in many areas in natural language processing, e.g., parsing, generation, lexicon building, word sense disambiguation, and information retrieving, etc.(e.g., Abney 1989, 1990; Benson et al. 1986; Yarowsky 1995; Church and Hanks 1989; Church, Gale, Hans, and Hindle 1989). But due to the huge number of words, it is impossible to list all compositions between words by hand in dictionaries. So an urgent problem occurs: how to automatically acquire word compositions?In general, word compositions fall into two categories: free compositions and bound compositions, i.e., collocations. Free compositions refer to those in which words can be replaced by other similar ones, while in bound compositions, words cannot be replaced freely(Benson 1990). Free compositions are predictable, i.e., their reasonableness can be determined according to the syntactic and semantic properties of the words in them. While bound compositions are not predictable, i.e., their reasonableness cannot be derived from the syntactic and semantic propertiesof the words in them(Smadja 1993).N ow with the availability of large-scale corpus, automatic acquisition of word compositions, especially word collocations from them have been extensively studied(e.g., Choueka et al. 1988; Church and Hanks 1989; Smadja 1993). The key of their methods is to make use of some statistical means, e.g., frequencies or mutual information, to quantify the compositional strength between words. These methods are more appropriate for retrieving bound compositions, while less appropriate for retrieving free ones. This is because in free compositions, words are related with each other in a more loose way, which may result in the invalidity of mutual information and other statistical means in distinguishing reasonable compositions from unreasonable ones.In this paper, we start from a different point to explore the problem of automatic acquisition of free compositions. Although we cannot list all free compositions, we can select some typical ones as those specified in some dictionaries(e.g., Benson 1986; Zhang et al. 1994). According to the properties held by free compositions, we can reasonably suppose that selected compositions can provide strong clues for others. Furthermore we suppose that words can be classified into clusters, with the members in each cluster similar in their compositional ability, which can be characterized as the set of the words able to combined with them to form meaningful phrases. Thus any given composition, although specifying the relation between two words literally, suggests the relation between two clusters. So for each word(or cluster), there exist some word clusters, the word (or the words in the cluster) can and only can combine with the words in the clusters to form meaningful phrases. We call the set of these clusters compositional frame of the word (or the cluster).A seemingly plausible method to determine compositional frames is to make use of pre-defined semantic classes in some thesauri(e.g., Miller et al. 1993; Mei et al. 1996). The rationale behind the method is to take such an assumption that if one word can be combined with another one to form a meaningful phrase, the words similar to them in meaning can also be combined with each other. But it has been shown that the similarity between words in meaning doesn’t correspond to the similarity in compositional ability(Zhu 1982). So adopting semantic classes to construct compositional frames will result in considerable redundancy.An alternative to semantic class is word cluster based on distributional environment (Brown et al., 1992), which in general refers to the surrounding words distributed around certain word (e.g., Hatzivassiloglou et al., 1993; Pereira et al., 1993), or the classes of them(Bensch et al., 1995), or more complex statistical means (Dagan et al., 1993). According to the properties of the clusters in compositional frames, the clusters should be based on the environment, which, however, is narrowed in the given compositions. Because the given compositions are listed by hand, it is impossible to make use of statistical means to form the environment, the remaining choices are surrounding words or classes of them.Pereira et al.(1993) put forward a method to cluster nouns in V-N compositions, taking the verbs which can combine with a noun as its environment. Although its goal is to deal with the problem of data sparseness, it suffers from the problem itself. A strategy to alleviate the effects of the problem is to cluster nouns and verbs simultaneously. But as a result, the problem of word clustering becomes a bootstrapping one, or a non-linear one: the environment is also to be determined. Bensch et al. (1995) proposed a definite method to deal with the generalized version of the non-linear problem, but it suffers from the problem of local optimization.In this paper, we focus on A-N compositions in Chinese, and explore the problem of learningnew compositions from given ones. In order to copy with the problem of sparseness, we take adjective clusters as nouns’ environment, and take noun clusters as adjectives’ environment. In order to avoid local optimal solutions, we propose a cooperative evolutionary strategy. The method uses no specific knowledge of A-N structure, and can be applied to other structures.The remainder of the paper is organized as follows: in section 2, we give a formal description of the problem. In section 3, we discuss a kind of cooperative evolution strategy to deal with the problem. In section 4, we explore the problem of parameter estimation. In section 5, we present our experiments and the results as well as their evaluation. In section 6, we give some conclusions and discuss future work.2. Problem SettingGiven an adjective set and a noun set, suppose for each noun, some adjectives are listed as its compositional instances1. Our goal is to learn new reasonable compositions from the instances. To do so, we cluster nouns and adjectives simultaneously and build a compositional frame for each noun.Suppose A is the set of adjectives, N is the set of nouns, for any a symbol 206 \f "Symbol" \s 10.5∈}A, let f(a)symbol 205 \f "Symbol" \s 10.5⊆}N be the instance set of a, i.e., the set of nouns in N which can be combined with a, and for any n symbol 206 \f "Symbol" \s 10.5∈}N, let g(n)symbol 205 \f "Symbol" \s 10.5⊆}A be the instance set of n, i.e., the set of adjectives in A which can be combined with n. We first give some formal definitions in the following:Definition 1 partitionSuppose U is a non-empty finite set, we call <U1, U2, ..., U k> a partition of U, if:i) for any U i, and U j, i symbol 185 \f "Symbol" \s 10.5≠}j, U i symbol 199 \f "Symbol" \s10.5∩}U j•symbol 102 \f "Symbol" \s 10.5φ,ii) U=U ii k1≤≤UWe call U i a cluster of U.Suppose U•< A1, A2, ..., A p > is a partition of A, V•<N1, N2, ..., N q> is a partition of N, f and g are defined as above, for any N i, let g(N i)•{A j:_symbol 36 \f "Symbol" \s 10.5∃n symbol 206 \f "Symbol" \s 10.5∈}N i, A j symbol 199 \f "Symbol" \s 10.5∩}g(n)symbol 185 \f "Symbol" \s 10.5≠}symbol 102 \f "Symbol" \s 10.5φ}, and for anyn, let δ<>U V n,()•symbol 124 \f "Symbol" \s 10.5|{a:_symbol 36 \f "Symbol" \s 10.5∃A j, A j symbol 206 \f "Symbol" \s 10.5∈}g(N k), a symbol 206 \f "Symbol" \s 10.5∈}A j}symbol 45 \f "Symbol" \s 10.5−g(n)symbol 124 \f "Symbol" \s 10.5|, where n symbol 206 \f "Symbol" \s 10.5∈}N k. Intuitively,δ<>U V n,()is the number of the new instances relevant with n. We define the general learning amount as the following:Definition 2 learning amountδ<>U V,1 The compositional instances of the adjectives can be inferred from those of the nouns.δ<>U V ,•δ<>∈∑n N n ,()Based on the partitions of both nouns and adjectives, we can define the distance between nouns and that between adjectives.Definition 3 distance between wordsfor any a symbol 206 \f "Symbol" \s 10.5∈}A , let f a ()={N i :_1symbol 163 \f "Symbol" \s 10.5≤}i symbol 163 \f "Symbol" \s 10.5≤}q , N i symbol 199 \f "Symbol" \s 10.5∩}f(a)symbol 185 \f "Symbol" \s 10.5≠}symbol 102 \f "Symbol" \s 10.5φ}, for any n symbol 206 \f "Symbol" \s 10.5∈}N , let g n U ()={A i :_1symbol 163 \f "Symbol" \s 10.5≤}i symbol 163 \f "Symbol" \s 10.5≤}p , A i symbol 199 \f "Symbol" \s 10.5∩}g(n)symbol 185 \f "Symbol" \s 10.5≠}symbol 102 \f "Symbol" \s 10.5φ}, for any two nouns n 1 and n 2, any two adjectives a 1 and a 2, we define the distances between them respectively as the following: i) dis n n U (,)12=1-g n g n g n g n U U U U ()()()()1212∩∪ii) dis a a V (,)12=1-f a f a f a f a V V V V ()()()()1212∩∪According to the distances between words, we can define the distances between word sets .Definition 4 distance between word setsGiven any two adjective sets X 1, X 2symbol 205 \f "Symbol" \s 10.5⊆}A , any two noun sets Y 1, Y 2symbol 205 \f "Symbol" \s 10.5⊆}N , their distances are:i) dis X X V (,)12=a X a X V dis a a 112212∈∈,max{(,)}ii) dis Y Y U (,)12 =n Y n Y dis n n 112212∈∈,max {(,)}Intuitively, the distance between word sets refer to the biggest distance between words respectively in the two sets.We formalize the problem of clustering nouns and adjectives simultaneously as an optimization problem with some constraints. (1)To determine a partition U •<A 1, A 2, ..., A p > of A , and a partition V •<N 1, N 2, ..., N q > of N , where p , q symbol 62 \f "Symbol" \s 10.5>0, which satisfies i) and ii), and minimize δ<>U V ,.i) for any a 1, a 2symbol 206 \f "Symbol" \s 10.5∈}A i , 1symbol 163 \f "Symbol" \s 10.5≤}i symbol 163 \f "Symbol" \s 10.5≤}p , dis a a (,)12<t 1; for A i and A j , 1symbol 163 \f "Symbol" \s 10.5≤}i symbol 185 \f "Symbol" \s 10.5≠}j symbol 163 \f "Symbol" \s 10.5≤}p , dis A A V i j (,)symbol 179 \f "Symbol" \s 10.5≥} t 1;ii) for any n 1, n 2symbol 206 \f "Symbol" \s 10.5∈}N i , 0symbol 163 \f"Symbol" \s 10.5≤}i symbol 163 \f "Symbol" \s 10.5≤}q , dis n n U (,)12<t 1; for N i and N j , 1symbol 163 \f "Symbol" \s 10.5≤}i symbol 185 \f "Symbol" \s 10.5≠}j symbol 163 \f "Symbol" \s 10.5≤}q , dis N N i j (,)symbol 179 \f "Symbol" \s 10.5≥} t 2;where 0symbol 163 \f "Symbol" \s 10.5≤}t 1, t 2symbol 163 \f "Symbol" \s 10.5≤}1.Intuitively, the conditions i) and ii) make the distances between words within clusters smaller, and those between different clusters bigger, and to minimize δ<>U V ,means to minimize the distances between the words within clusters. In fact, (U , V ) can be seen as an abstraction model over given compositions, and t 1, t 2 can be seen as its abstraction degree . Consider the two special case: one is t 1=t 2 =0, i.e., the abstract degree is the lowest, when the result is that one noun forms a cluster and on adjective forms a cluster, which means that no new compositions are learned. The other is t 1=t 2 =1, the abstract degree is the highest, when a possible result is that all nouns form a cluster and all adjectives form a cluster, which means that all possible compositions, reasonable or unreasonable, are learned. So we need estimate appropriate values for the two parameters, in order to make an appropriate abstraction over given compositions, i.e., make the compositional frames contain as many reasonable compositions as possible, and as few unreasonable ones as possible.3. Cooperative EvolutionSince the beginning of evolutionary algorithms, they have been applied in many areas in AI(Davis et al., 1991; Holland 1994). Recently, as a new and powerful learning strategy,cooperative evolution has gained much attention in solving complex non-linear problem. In this section, we discuss how to deal with the problem (1) based on the strategy.According to the interaction between adjective clusters and noun clusters, we adopt such a cooperative strategy: after establishing the preliminary solutions, for any preliminary solution, we optimize N ’s partition based on A ’s partition, then we optimize A ’s partition based on N ’s partition, and so on, until the given conditions are satisfied.3.1 Preliminary SolutionsWhen determining the preliminary population, we also cluster nouns and adjectives respectively.However, we see the environment of a noun as the set of all adjectives which occur with it in given compositions, and that of an adjective as the set of all the nouns which occur with it in given compositions. Compared with (1), the problem is a linear clustering one.Suppose a 1, a 2symbol 206 \f "Symbol" \s 10.5∈}A , f is defined as above, we define the linear distance between them as (2):(2) dis (a 1, a 2)•1-f a f a f a f a ()()()()1212∩∪Similarly, we can define the linear distance between nouns dis (n 1, n 2) based on g . In contrast, we call the distances in definition 3 non-linear distances .According to the linear distances between adjectives, we can determine a preliminary partition of N : randomly select an adjective and put it into an empty set X , then scan the otheradjectives in A , for any adjective in A -X, if its distances from the adjectives in X are all smaller than t 1, then put it into X , finally X forms a preliminary cluster. Similarly, we can build another preliminary cluster in (A -X ). So on, we can get a set of preliminary clusters, which is just a partition of A . According to the different order in which we scan the adjectives, we can get different preliminary partitions of A .Similarly, we can determine the preliminary partitions of N based on the linear distances between nouns. A partition of A and a partition of N forms a preliminary solution of (1), and all possible preliminary solutions forms the population of preliminary solutions, which we also call the population of 0th generation solutions.3.2 Evolution OperationIn general, evolution operation consists of recombination, mutation and selection. Recombination makes two solutions in a generation combine with each other to form a solution belonging to nextgeneration. Suppose and are two ith generation solutions, whereU i 1() and U i 2() are two partitions of A , V i 1() and V i 2() are two partitions of N , then and forms two possible (i +1)th generation solutions.Mutation makes a solution in a generation improve its fitness , and evolve into a new onebelonging to next generation. Suppose is a ith generation solution, whereU i ()•<A 1, A 2, ..., A p >•V i ()•<N 1, N 2, ..., N q > are partitions of A and N respectively, the mutation is aimed at optimizing Vi () into V i ()£«1 based on U i (), and makes V i ()£«1 satisfy the condition ii)in (1), or optimizing U i () into Ui ()£«1 based on V i (), and makes U i ()£«1 satisfy the condition i)in (1), then moving words across clusters to minimize δ<>U V ,.We design three steps for mutation operation: splitting , merging and moving , the former two are intended for the partitions to satisfy the conditions in (1), and the third intended to minimizeδ<>U V ,. In the following, we take the evolution of V i ()£«1 as an example to demonstrate the three steps.symbol 183 \f "Symbol" \s 10.5•} Splitting Procedure . For any N k , 1symbol 163 \f "Symbol"\s 10.5≤}k symbol 163 \f "Symbol" \s 10.5≤}q , if there exist n 1, n 2symbol 206 \f "Symbol" \s 10.5∈}N k , such that dis n n U i ()(,)12symbol 179 \f "Symbol" \s 10.5≥} t 2, then splitting N k into two subsets X and Y . The procedure is given as the following:i) Put n 1 into X , n 2 into Y ,ii) Select the noun in (N k -(X symbol 200 \f "Symbol" \s 10.5∪}Y )) whose distance from n 1is the smallest, and put it into X ,iii) Select the noun in (N k -(X symbol 200 \f "Symbol" \s 10.5∪}Y )) whose distance from n 2is the smallest, and put it into Y,iv) Repeat ii) and iii), until X symbol 200 \f "Symbol" \s 10.5∪}Y = N k .For X (or Y ), if there exist n 1, n 2symbol 206 \f "Symbol" \s 10.5∈}X (or Y ), dis n n U i ()(,)12symbol 179 \f "Symbol" \s 10.5≥} t 2, then we can make use of the above procedure to split it into moresmaller sets. Obviously, we can split any N k in V i () into several subsets which satisfy thecondition ii) in (1) by repeating the procedure.symbol 183 \f "Symbol" \s 10.5•} Merging procedure .

We call moving n from N j to N k a word move , where 1symbol 163 \f "Symbol" \s 10.5≤}j symbol 185 \f "Symbol" \s 10.5≠}k symbol 163 \f "Symbol" \s 10.5≤}q , denoted as (n , N j , N k ), if the condition (ii) remains satisfied. The procedure is as the following:i) Select a word move (n , N j , N k ) which minimizes δ<>U V ,,ii) Move n from N j to N k ,iii) Repeat i) and ii)•until there are no word moves which reduce δ<>U V ,.After the three steps, U i ()and V i () evolve into U i ()£«1and V i ()£«1 respectively.Selection operation selects the solutions among those in the population of certain generation according to their fitness. We define the fitness of a solution as its learning amount.We use J i to denote the set of ith generation solutions, H (i , i+1), as in (3), specifies the similarity between ith generation solutions and (i +1)th generation solutions.(3) H (i , i+1)=Min U V J Min U V J U V i i i U V i i i i i i i {:_(,)}{:_(,)}()()()(),()(),()()δδ<>+++<>++∈∈11111Let t 3 be a threshold for H (i , i+1), the following is the general evolutionary algorithm:Procedure Clustering (A , N , f , g );begini) Build preliminary solution population I 0,ii) Determine 0th generation solution set J 0 according to their fitness,iii) Determine I i+1 based on J i :a) Recombination: if (U i 1(),V i 1()), (U i 2(),V i 2())symbol 206 \f "Symbol" \s10.5∈}J i , then (U i 1(),V i 2()), (U i 2(),V i 1())symbol 206 \f "Symbol" \s10.5∈}I i+1,b) Mutation: if (U i (),V i ())symbol 206 \f "Symbol" \s 10.5∈}J i , then(U i (),V i ()£«1), (U i ()£«1,V i ())symbol 206 \f "Symbol" \s 10.5∈}I i+1,iv) Determine J i+1 from I i+1 according to their fitness,v) If H (i ,i+1)>t 3, then exit, otherwise goto iii),end •After determining the clusters of adjectives and nouns, we can construct the compositional frame for each noun cluster or each noun. In fact, for each noun cluster N i , g (N i )={A j :_symbol 36 \f "Symbol" \s 10.5∃n symbol 206 \f "Symbol" \s 10.5∈}N i , A j symbol 199 \f "Symbol" \s 10.5∩}g (n )symbol 185 \f "Symbol" \s 10.5≠}symbol 102 \f"Symbol" \s 10.5φ} is just its compositional frame, and for any noun in N i , g (N i ) is also its compositional frame. Similarly, for each adjective (or adjective cluster), we can also determine its compositional frame.4. Parameter EstimationThe parameters t 1 and t 2 in (1) are the thresholds for the distances between the clusters of A and N respectively. If they are too big, the established frame will contain more unreasonable compositions, on the other hand, if they are too small, many reasonable compositions may not be included in the frame. Thus, we should determine appropriate values for t 1 and t 2, which makes the fame contain as many reasonable compositions as possible, meanwhile as few unreasonable ones as possible.Suppose F i is the compositional frame of N i , let F =<F 1, F 2, ..., F q >, for any F i , let A F i •{a :_symbol 36 \f "Symbol" \s 10.5∃X symbol 206 \f "Symbol" \s 10.5∈}F i , a symbol 206 \f "Symbol" \s 10.5∈}X }. Intuitively, A F i is the set of the adjectives learned as the compositionalinstances of the noun in N i . For any n symbol 206 \f "Symbol" \s 10.5∈}N i , we use A n to denote the set of all the adjectives which in fact can modify n to form a meaningful phrase, we now define deficiency rate and redundancy rate of F . For convenience, we use symbol 100 \f "Symbol" \s 10.5δF to represent symbol 100 \f "Symbol" \s 10.5δ(, ).Definition 5 Deficiency rate symbol 97 \f "Symbol" \s 10.5αFsymbol 97 \f "Symbol" \s 10.5αF = n N n F i q nn N i iA A A∈≤≤∈∑∑∑−1Intuitively, symbol 97 \f "Symbol" \s 10.5αF refers to the ratio between the reasonable compositions which are not learned and all the reasonable ones.Definition 6 Redundancy rate symbol 98 \f "Symbol" \s 10.5βFsymbol 98 \f "Symbol" \s 10.5βF •n N F ni q Fi i A A ∈≤≤∑∑−1δIntuitively, symbol 98 \f "Symbol" \s 10.5βF refers to the ratio between unreasonable compositions which are learned and all the learned ones.So the problem of estimating t 1 and t 2 can be formalized as (5):(5) to find t 1 and t 2, which makes symbol 97 \f "Symbol" \s 10.5αF =0, and symbol 98 \f "Symbol" \s 10.5βF =0.But, (5) may exists no solutions, because its constraints are two strong, on one hand, the sparseness of instances may cause symbol 97 \f "Symbol" \s 10.5αF not to get 0 value, even if t 1and t 2 close to 1, on the other hand, the difference between words may cause symbol 98 \f "Symbol" \s 10.5βF not to get 0 value, even if t 1 and t 2 close to 0. So we need to weaken (5).In fact, both symbol 97 \f "Symbol" \s 10.5αF and symbol 98 \f "Symbol" \s 10.5βF can be seen as the functions of t 1 and t 2, denoted as symbol 97 \f "Symbol" \s 10.5αF (t 1, t 2) and symbol 98 \f "Symbol" \s 10.5βF (t 1,t 2) respectively. Given some values for t 1 and t 2, we can compute symbol 97\f "Symbol" \s 10.5αF and symbol 98 \f "Symbol" \s 10.5βF . Although there may exist no values (t 1*, t 2*) for (t 1, t 2), such that symbol 97 \f "Symbol" \s 10.5αF (t 1*, t 2*)=symbol 98 \f "Symbol" \s 10.5βF (t 1*, t 2*)=0, but with t 1 and t 2 increasing, symbol 97 \f "Symbol" \s 10.5αF tends to decrease, while symbol 98 \f "Symbol" \s 10.5βF tends to increase. So we can weaken (5) as (6).(6) to find t 1 and t 2, which maximizes (7).

So the former part of (7) is the mean deficiency rate of the points in T 1(t 1*, t 2*), and the latter part of (7) is the mean deficiency rate of the points in T 2(t 1*, t 2*). To maximize (7) means to maximize its former part, while to minimize its latter part. So ourweakening (5) into (6) lies in finding a point (t 1*, t 2*), such that the mean deficiency rate of thesample points in T 2(t 1*, t 2*) tends to be very low, rather than finding a point(t 1*, t 2*), such that its deficiency rate is 0.5 Experiment Results and EvaluationWe randomly select 30 nouns and 43 adjectives, and retrieve 164 compositions(see Appendix I)between them from Xiandai Hanyu Cihai (Zhang et al. 1994), a word composition dictionary of Chinese. After checking by hand, we get 342 reasonable compositions(see Appendix I), among which 177 ones are neglected in the dictionary. So the sufficiency rate 2(denoted as symbol 103 \f "Symbol" \s 10.5γ) of these given compositions is 47.9%.We select 0.95 as the value of t 3, and let t 1=0.0, 0.1, 0.2, …, 1.0, t 2=0.0, 0.1, 0.2, …, 1.0respectively, we get 121 groups of values for symbol 97 \f "Symbol" \s 10.5αF and symbol 98 \f "Symbol" \s 10.5βF . Fig.1 and Fig.2 demonstrate the distribution of symbol 97 \f "Symbol" \s 10.5αF and symbol 98 \f "Symbol" \s 10.5βF respectively.2 Sufficiency rate refers to the ratio between given reasonable compositions and all reasonable ones.19deficiencyratet2t1 Fig. 1 The distribution of symbol 97 \f "Symbol" \s 10.5αF.19redundancerate(%)t2(1/10)t1(1/10)Fig. 2 The distribution of symbol 98 \f "Symbol" \s 10.5βF.For any given t1, and t2,we found (7) get its biggest value when t1=0.4 and t2=0.4, so we select 0.4 as the appropriate value for both t1 and t2. The result is listed in Appendix II. From Fig.1 and Fig.2, we can see that when t1=0.4 and t2=0.4, both symbol 97 \f "Symbol" \s 10.5αF and symbol 98 \f "Symbol" \s 10.5βF get smaller values. With the two parameters increasing, symbol 97 \f "Symbol" \s 10.5αF decreases slowly, while symbol 98 \f "Symbol" \s 10.5βF increases severely, which demonstrates the fact that the learning of new compositions from the given ones has reached the limit at the point: the other reasonable compositions will be learned at a cost of severely raising the redundancy rate.From Fig.1, we can see that symbol 97 \f "Symbol" \s 10.5αF generally increases as t1 and t2 increase, this is because that to increase the thresholds of the distances between clusters means to raise the abstract degree of the model, then more reasonable compositions will be learned. On the other hand, we can see from Fig.2 that when t1symbol 179 \f "Symbol" \s 10.5≥}0.4, t2symbol 179 \f "Symbol" \s 10.5≥}0.4, symbol 98 \f "Symbol" \s 10.5βF roughly increases as t1 and t2 increase3,3 On some points, it may be not the case.。

It was so much fun and exciting!It all started when my big brother got a new bike for his birthday. I was so jealous and wanted to ride it too. My brother said he would teach me how to ride it, but I was a bit scared at first. I didn't want to fall and get hurt.But my brother told me not to worry and that he would help me. He put training wheels on the bike and showed me how to balance and pedal. I kept practicing every day in our backyard until I could ride without falling.After a week, I asked my brother to take off the training wheels. I was nervous, but he said I could do it.
