Article Summary:
This article demystifies Noise Contrastive Estimation (NCE), a machine learning method used for estimating the parameters of a statistical distribution by differentiating between real data and noise. The article discusses two variants of NCE, Local NCE and Global NCE, as well as InfoNCE, a related technique for partition function estimation.
