Maximum entropy modelsSupervised machine learning 词义消歧最大熵原理汉语自然语言处理机器学习方法最大熵模型关键问题知识表示Word sense disambiguation is a crucial problem to be solved in NLP. A supervised machine learning method is proposed in this paper, which is applied in word disambiguation in ...
Maximum Entropy In subject area: Computer Science Maximum Entropy refers to the principle of determining the distribution that maximizes uncertainty or entropy based on given constraints. By applying this principle, biases and assumptions are eliminated, allowing for the combination of information from ...
Maximum Entropy Model LING 572 Fei Xia 02/07-02/09/06 History • The concept of Maximum Entropy can be traced back along multiple threads to Biblical times. • Introduced to NLP area by Berger et. Al. (1996). • Used in many NLP tasks: MT, Tagging, Parsing, PP attachment, LM,...

19.2.1 Background: Maximum Entropy Theory As its name suggests, the maximum entropy model is intimately related to probability theory. We now give details on the model in order to understand and implement the objective function being optimized. Let X be the D× N matrix of training data, as...
Estimating a mixed strategy employing maximum entropy(估计采用最大熵的混合策略) 热度: Maxent 热度: Maxent Models and Discriminative Estimation Generative vs. Discriminative models Christopher Manning Christopher Manning Introduction • So far we’ve looked at “generative models” ...
1.The use of state-observation transition functions rather than the separate transition and observation functions in HMMs allows us to model transitions in terms of multiple, nonindependent features of observations, which we believe to be the most valuable contribution of the present work. ...
Maximum-entropy Markov model author: Emily Hua Goal: implement MEMM to predict BOI tags Information about the program: some non-ASCII chars(mainly punctuations) may break the stemmer: replace them with ASCII punc. It has two programs: MEMM_1.py and MEMM_2.py; 1 python pickle file: my_...
