• Title: ConsistentFeature: A Plug-and-Play Component for Neural Network Regularization
• Authors: RuiZhe Jiang, Haotian Lei,
• Abstract summary: Over- parameterized neural network models often lead to significant performance discrepancies between training and test sets. We introduce a simple perspective on overfitting: models learn different representations in different i.i.d. datasets. We propose an adaptive method, ConsistentFeature, that regularizes the model by constraining feature differences across random subsets of the same training set.

• Abstract: Over-parameterized neural network models often lead to significant performance discrepancies between training and test sets, a phenomenon known as overfitting. To address this, researchers have proposed numerous regularization techniques tailored to various tasks and model architectures. In this paper, we introduce a simple perspective on overfitting: models learn different representations in different i.i.d. datasets. Based on this viewpoint, we propose an adaptive method, ConsistentFeature, that regularizes the model by constraining feature differences across random subsets of the same training set. Due to minimal prior assumptions, this approach is applicable to almost any architecture and task. Our experiments show that it effectively reduces overfitting, with low sensitivity to hyperparameters and minimal computational cost. It demonstrates particularly strong memory suppression and promotes normal convergence, even when the model has already started to overfit. Even in the absence of significant overfitting, our method consistently improves accuracy and reduces validation loss.

  This paper studies the performance of overfitted meta-learning under a linear regression model with Gaussian features. We find new and interesting properties that do not exist in single-task linear regression. Our analysis suggests that benign overfitting is more significant and easier to observe when the noise and the diversity/fluctuation of the ground truth of each training task are large.
