Learning Compact Features via In-Training Representation Alignment

AAAI 2023technical

Deep neural networks (DNNs) for supervised learning can be viewed as a pipeline of the feature extractor (i.e., last hidden layer) and a linear classifier (i.e., output layer) that are trained jointly with stochastic gradient descent (SGD) on the loss function (e.g., cross-entropy). In each epoch, t…

Improving Adversarial Robustness via Probabilistically Compact Loss with Logit Constraints

AAAI 2021technical

Convolutional neural networks (CNNs) have achieved state-of-the-art performance on various tasks in computer vision. However, recent studies demonstrate that these models are vulnerable to carefully crafted adversarial samples and suffer from a significant performance drop when predicting them. Many…

Explainable Recommendation via Interpretable Feature Mapping and Evaluation of Explainability

IJCAI 2020poster

Latent factor collaborative filtering (CF) has been a widely used technique for recommender system by learning the semantic representations of users and items. Recently, explainable recommendation has attracted much attention from research community. However, trade-off exists between explainability…

Proximal Deep Recurrent Neural Network for Monaural Singing Voice Separation

ICASSP 2019accepted

The recent deep learning methods can offer state-of-the-art performance for Monaural Singing Voice Separation (MSVS). In these deep methods, the recurrent neural network (RNN) is widely employed. This work proposes a novel type of Deep RNN (DRNN), namely Proximal DRNN (P-DRNN) for MSVS, which improv…
