Noise-Contrastive Estimation and InfoNCE: How Partition Function Estimation and Mutual Information Lower Bounds Power Modern AI
Noise-Contrastive Estimation and InfoNCE: How Partition Function Elimination and Mutual Information Lower Bounds Power Modern AI In statistical machine learning and generative modeling, evaluating the exact probability of an observed event frequently requires calculating a normalizing constant known as the partition function. For continuous spaces or discrete spaces with high cardinality, such as a natural language vocabulary spanning over one hundred thousand tokens or high-dimensional pixel d
