Mixtures of ranking models are standard tools for ranking problems.

PBoS: Probabilistic Bag-of-Subwords for Generalizing Word Embedding

1 code implementation Findings of the Association for Computational Linguistics 2020 Zhao Jinman, Shawn Zhong, Xiaomin Zhang, YIngyu Liang

We look into the task of \emph{generalizing} word embeddings: given a set of pre-trained word vectors over a finite vocabulary, the goal is to predict embedding vectors for out-of-vocabulary words, \emph{without} extra contextual information.

Provable Training Set Debugging for Linear Regression

no code implementations16 Jun 2020 Xiaomin Zhang, Xiaojin Zhu, Po-Ling Loh

We first formulate a general statistical algorithm for identifying buggy points and provide rigorous theoretical guarantees under the assumption that the data follow a linear model.
