Pretrained Knowledge Base Embeddings for improved Sentential Relation Extraction

1 code implementation ACL 2022 Andrea Papaluca, Daniel Krefl, Hanna Suominen, Artem Lenskiy

In this work we put forward to combine pretrained knowledge base graph embeddings with transformer based language models to improve performance on the sentential Relation Extraction task in natural language processing.

CILex: An Investigation of Context Information for Lexical Substitution Methods

1 code implementation COLING 2022 Sandaru Seneviratne, Elena Daskalaki, Artem Lenskiy, Hanna Suominen

Methods based on lexical resources are likely to miss relevant substitutes whereas relying only on contextual word embedding models fails to provide adequate information on the impact of a substitute in the entire context and the overall meaning of the input.

Realistic Counterfactual Explanations with Learned Relations

no code implementations15 Feb 2022 Xintao Xiang, Artem Lenskiy

Many existing methods of counterfactual explanations ignore the intrinsic relationships between data attributes and thus fail to generate realistic counterfactuals.

A movie genre prediction based on Multivariate Bernoulli model and genre correlations

no code implementations25 Mar 2016 Eric Makita, Artem Lenskiy

Furthermore, movie ratings are crucial for recommendation engines that track the behavior of all users and utilize the information to suggest items they might like.

A multinomial probabilistic model for movie genre predictions

1 code implementation25 Mar 2016 Eric Makita, Artem Lenskiy

We employ mulitnomial event model to estimate a likelihood of a movie given genre and the Bayes rule to evaluate the posterior probability of a genre given a movie.
