Noise Contrastive Estimation and Negative Sampling for Conditional Models: Consistency and Statistical Efficiency

no code implementations EMNLP 2018 Zhuang Ma, Michael Collins

Noise Contrastive Estimation (NCE) is a powerful parameter estimation method for log-linear models, which avoids calculation of the partition function or its derivatives at each training step, a computationally demanding step in many cases.

Finding Linear Structure in Large Datasets with Scalable Canonical Correlation Analysis

no code implementations26 Jun 2015 Zhuang Ma, Yichao Lu, Dean Foster

In this paper, we tackle the problem of large scale CCA, where classical algorithms, usually requiring computing the product of two huge matrices and huge matrix decomposition, are computationally and storage expensive.
