Understanding Top-k and Top-p (Nucleus) Sampling in Natural Language Processing

Leave a Comment / All Post /

Introduction to Sampling in NLP Sampling is a fundamental concept in Natural Language Processing (NLP) that plays a critical role in generating human-like text. It refers to the method by which potential outcomes, or tokens, are selected from a probability distribution during text generation. In essence, sampling enables models to produce varied responses rather than […]

Understanding L1 and L2 Regularization: Key Differences and Applications

Leave a Comment / All Post /

Introduction to Regularization In the realm of machine learning, regularization serves as a crucial technique aimed at preventing overfitting, which is a common issue encountered when building predictive models. Overfitting occurs when a model learns not just the underlying patterns in the training data but also the noise, leading to poor generalization on unseen data.
