Mitigating Exploitation Bias in Learning to Rank with an Uncertainty-aware Empirical Bayes Approach

no code implementations26 May 2023 Tao Yang, Cuize Han, Chen Luo, Parth Gupta, Jeff M. Phillips, Qingyao Ai

While previous studies have demonstrated the effectiveness of using user behavior signals (e. g., clicks) as both features and labels of LTR algorithms, we argue that existing LTR algorithms that indiscriminately treat behavior and non-behavior signals in input features could lead to suboptimal performance in practice.

Enrichment of Bilingual Dictionary through News Stream Data

no code implementations LREC 2014 Ajay Dubey, Parth Gupta, Vasudeva Varma, Paolo Rosso

Many time the language pair does not have large bilingual comparable corpora and in such cases the best automatic dictionary is upper bounded by the quality and coverage of such corpora.

Squeezing bottlenecks: exploring the limits of autoencoder semantic representation capabilities

no code implementations13 Feb 2014 Parth Gupta, Rafael E. Banchs, Paolo Rosso

We present a comprehensive study on the use of autoencoders for modelling text data, in which (differently from previous studies) we focus our attention on the following issues: i) we explore the suitability of two different models bDA and rsDA for constructing deep autoencoders for text data at the sentence level; ii) we propose and evaluate two novel metrics for better assessing the text-reconstruction capabilities of autoencoders; and iii) we propose an automatic method to find the critical bottleneck dimensionality for text language representations (below which structural information is lost).
