On the generalization mystery
Web25 de fev. de 2024 · An open question in the Deep Learning community is why neural networks trained with Gradient Descent generalize well on real datasets even though they are capable of fitting random data. We propose an approach to answering this question based on a hypothesis about the dynamics of gradient descent that we call Coherent … Web11 de abr. de 2024 · Data anonymization is a widely used method to achieve this by aiming to remove personal identifiable information (PII) from datasets. One term that is frequently used is "data scrubbing", also referred to as "PII scrubbing". It gives the impression that it’s possible to just “wash off” personal information from a dataset like it's some ...
On the generalization mystery

WebThe generalization mystery of overparametrized deep nets has motivated efforts to understand how gradient descent (GD) converges to low-loss solutions that generalize well. Real-life neural networks are initialized from small random values and trained with cross-entropy loss for classification (unlike the "lazy" or "NTK" WebEfforts to understand the generalization mystery in deep learning have led to the belief that gradient-based optimization induces a form of implicit regularization, a bias towards models of low “complexity.” We study the implicit regularization of gradient descent over deep linear neural networks for matrix completion and sens-
WebWe study the implicit regularization of gradient descent over deep linear neural networks for matrix completion and sensing, a model referred to as deep matrix factorization. Our first finding, supported by theory and experiments, is that adding depth to a matrix factorization enhances an implicit tendency towards low-rank solutions, oftentimes ...
