Parameter-Norm-Penalties
Parameter norm penalties are techniques used in machine learning to regularize models by constraining the values of their parameters. These penalties help prevent overfitting by adding a cost to the loss function based on the size of the parameters. Common types of norm penalties include L1 and L2 norms. The L1 norm encourages sparsity in the model, effectively driving some parameters to zero, while the L2 norm penalizes large weights, promoting smaller, more evenly distributed parameter values. By incorporating these penalties, models can achieve better generalization and improved performance on unseen data.
