Physical Review Research2020Topological entanglement entropy has been extensively used as an indicator of topologically ordered phases. We study conditions for two-dimensional topologically trivial states to exhibit spurious contributions which suffer topological entanglement entropy. We show that if the state at the boundary of a subregion is a stabilizer state, then it has non-zero spurious contribution on the region if, and only

Interspeech 20202020Speaker identification based on voice input is a fundamental capability in speech processing enabling versatile downstream applications, such as personalization and authentication. With the advent of deep learning, most state-of-the-art methods apply machine learning techniques and derive acoustic embeddings from utterances with convolutional neural networks (CNNs) and recurrent neural networks (RNNs).

Interspeech 20202020Entity Linking (EL) recognizes textual mentions of entities and maps them to the corresponding entities in a Knowledge Graph (KG). In this paper, we propose a novel method for EL on short text using entity representations base on their name labels, descriptions, and other related entities in the KG. We then leverage a pre-trained BERT model to calculate the semantic similarity between the entity and the

CIKM 20202020Personalization is a crucial aspect of many online experiences. In particular, content ranking is often a key component in delivering sophisticated personalization results. Commonly, supervised learning-to-rank methods are applied, which suffer from bias introduced during data collection by production systems in charge of producing the ranking. To compensate for this problem, we leverage contextual multi-armed

Interspeech 20202020General embeddings like word2vec, GloVe and ELMo have shown a lot of success in natural language tasks. The embeddings are typically extracted from models that are built on general tasks such as skip-gram models and natural language generation. In this paper, we extend the work from natural language understanding to multi-modal architectures that use audio, visual and textual information for machine learning
