Regularization
A set of techniques used to prevent overfitting in machine learning models. Common forms include L1 (Lasso) and L2 (Ridge) regularization, which constrain model complexity by adding penalty terms to the loss function during training.
Core Facts
Timeline (last 90 days)
Methods to mitigate overfitting and improve generalization include data augmentation (rotation, cropping, brightness adjustment), regularization, Dropout, and introducing more real-world samples.
Commonly used regularization strategies (such as L1, L2, or more general convex penalties) do not make the optimization problem inherently harder to solve at the level of oracle complexity.
Frequently tested interview topics include model evaluation metrics, overfitting and regularization, and cross-validation.
In the Bayesian framework, the prior plays the role of regularization, and adding a regularization term is essentially equivalent to introducing a certain prior distribution for the parameters.
Common strategies for addressing overfitting on small datasets include data augmentation, regularization techniques (such as Dropout and weight decay), early stopping, and controlling model capacity.
Methods for addressing overfitting include increasing training data, regularization, early stopping, and Dropout.
Dropout in deep learning can be interpreted as a form of Bayesian approximation.
