Probing classifiers have emerged as one of the prominent methodologies for interpreting and analyzing deep neural network models of natural language processing. To learn better probes, we proposed deep linear generator networks that significantly reduce overfitting through a combination of implicit regularization and data-specific inductive bias. We use linear classifiers, which we refer to as "probes", trained entirely independently of the model itself. 2 Background and Problem Statement Linear probing, while effective in many cases, is fundamentally limited by its simplicity. Deep linear networks trained with gradient descent yield low rank solutions, as is typically studied in matrix factorization.
