Understanding the Weaker Double Descent Phenomenon in Very Wide Networks

Leave a Comment / All Post /

Introduction to Double Descent Double descent is a phenomenon observed in machine learning where the performance of a model, particularly its error rate, exhibits a non-monotonic behavior as the model’s complexity increases. This intriguing behavior is especially significant as it challenges traditional paradigms associated with the bias-variance trade-off— a foundational concept in statistical learning that

Understanding Adversarial Examples: The Role of Sharp Loss Minima

Leave a Comment / All Post /

Introduction to Adversarial Examples Adversarial examples are inputs to machine learning models that have been intentionally modified in a subtle manner, resulting in a misclassification by the model. These modifications are often so minor that they are nearly imperceptible to human observers, yet they can lead to significant errors in prediction by artificial intelligence systems.
