Linear chain conditional random fields, hidden Markov models, and related classifiers

no code implementations3 Jan 2023 Elie Azeraf, Emmanuel Monfrini, Wojciech Pieczynski

Practitioners use Hidden Markov Models (HMMs) in different problems for about sixty years.

Deriving discriminative classifiers from generative models

no code implementations3 Jan 2022 Elie Azeraf, Emmanuel Monfrini, Wojciech Pieczynski

A discriminative model is directly given by $p(x | y)$, which is used to compute discriminative classifiers.

On equivalence between linear-chain conditional random fields and hidden Markov chains

no code implementations14 Nov 2021 Elie Azeraf, Emmanuel Monfrini, Wojciech Pieczynski

HMCs belong to the family of generative models and they are often compared to discriminative models, like conditional random fields (CRFs).

Introducing the Hidden Neural Markov Chain framework

no code implementations17 Feb 2021 Elie Azeraf, Emmanuel Monfrini, Emmanuel Vignon, Wojciech Pieczynski

However, if many works create extensions and improvements of the RNN, few have focused on developing other ways for sequential data processing with neural networks in a "term-to-term" way.

Highly Fast Text Segmentation With Pairwise Markov Chains

no code implementations17 Feb 2021 Elie Azeraf, Emmanuel Monfrini, Emmanuel Vignon, Wojciech Pieczynski

Natural Language Processing (NLP) models' current trend consists of using increasingly more extra-data to build the best models as possible.

Using the Naive Bayes as a discriminative classifier

no code implementations25 Dec 2020 Elie Azeraf, Emmanuel Monfrini, Wojciech Pieczynski

Related to this point, we show that the Logistic Regression can be viewed as a particular case of the Naive Bayes used in a discriminative way.

Hidden Markov Chains, Entropic Forward-Backward, and Part-Of-Speech Tagging

no code implementations21 May 2020 Elie Azeraf, Emmanuel Monfrini, Emmanuel Vignon, Wojciech Pieczynski

We illustrate the efficiency of HMC using EFB in Part-Of-Speech Tagging, showing its superiority over MEMM based restoration.
