Main Abstract:
This paper is about regularizing deep convolutional networks (ConvNets) based on an adaptive multi-objective framework for transfer learning with limited training data in the target domain. Recent advances of ConvNets regularization in this context are commonly due to the use of additional regularization objectives. They guide the training away from the target task using some concrete tasks. Unlike those related approaches, we report that an objective without a concrete goal can serve surprisingly well as a regularizer. In particular, we demonstrate Pseudo-task Regularization (PtR) which dynamically regularizes a network by simply attempting to regress image representations to a pseudo-target during fine-tuning. Through numerous experiments, the improvements on classification accuracy by PtR are shown greater or on a par to the recent state-of-the-art methods. These results also indicate a room for rethinking on the requirements for a regularizer, i.e., if specifically designed task for regularization is indeed a key ingredient. The contributions of this paper are: a) PtR provides an effective and efficient alternative for regularization without dependence on concrete tasks or extra data; b) desired strength of regularization effect in PtR is dynamically adjusted and maintained based on the gradient norms of the target objective and the pseudo-task.

[1]: During a long period of time we are combating overfitting in the CNN training process with model regularization, including weight decay, model averaging, data augmentation, etc. In this paper, we present DisturbLabel, an extremely simple algorithm which randomly replaces a part of labels as incorrect values in each iteration. Although it seems weird to intentionally generate incorrect training labels, we show that DisturbLabel prevents the network training from over-fitting by implicitly averaging over exponentially many networks which are trained with different label sets. To the best of our knowledge, DisturbLabel serves as the first work which adds noises on the loss layer. Meanwhile, DisturbLabel cooperates well with Dropout to provide complementary regularization functions. Experiments demonstrate competitive recognition results on several popular image recognition datasets.
Regularization methods that are commonly used for fine-tuning ConvNets can be generally grouped into four categories: data perturbation, parameter norm penalty, dropout, and multi-task learning. Image augmentation as a popular form of image perturbation has been proven to be particularly useful to prevent ConvNets from overfitting. In this paper, we also assume to perturb our training instances by random augmentations. The supervision signal can be perturbed for better regularization as well. This can be achieved by learning to predict soft targets rather than hard binary ones as in [1] . In this work, label perturbation is not considered so that we can deliver more ablated studies on the effectiveness of auxiliary training objectives.
