Personalization plays a critical role in helping customers discover the products and contents they prefer for e-commerce stores. Personalized recommendations differ in contents, target customers, and UI. However, they require a common core capability - the ability to deeply understand customers’ preferences and shopping intents. In this paper, we introduce the MCM (Multi-task pre-trained Customer Model)

Audio privacy has been undertaken using adversarial task training or adversarial models based on GANs, where the models also suppress scoring of other attributes (e.g., emotion, etc.), but embeddings still retain enough information to bypass speaker privacy. We use methods for feature importance from the explainability literature to modify embeddings from adversarial task training, providing a simple and

Speech super-resolution is the process of estimating the missing frequency content of a speech signal from its existing band-limited frequency content. The loss of frequency components is a common occurrence that can be because of a low sampling rate, low-quality microphones, or various transmission factors, and it is an increasingly common problem as bandwidth for high-quality communications is generally

We introduce a novel class of sample-based explanations we term high-dimensional representers, that can be used to explain the predictions of a regularized high-dimensional model in terms of importance weights for each of the training samples. Our workhorse is a novel representer theorem for general regularized high-dimensional models, which decomposes the model prediction in terms of contributions from

The eXtreme Multi-label Classification (XMC) problem seeks to find relevant labels from an exceptionally large label space. Most of the existing XMC learners focus on the extraction of semantic features from input query text. However, conventional XMC studies usually neglect the side information of instances and labels, which can be of use in many real-world applications such as recommendation systems and
