Interspeech 20192019Machine learning approaches for building task-oriented dialogue systems require large conversational datasets with labels to train on. We are interested in building task-oriented dialogue systems from human-human conversations, which may be available in ample amounts in existing customer care center logs or can be collected from crowd workers. Annotating these datasets can be prohibitively expensive. Recently

ICCV 20192019Action recognition has seen a dramatic performance improvement in the last few years. Most of the current state-of-the-art literature either aims at improving performance through changes to the backbone CNN network, or they explore different trade-offs between computational efficiency and performance, again through altering the backbone network. However, almost all of these works maintain the same last

Interspeech 20192019In automatic speech recognition, confidence measures provide a quantitative representation used to assess the reliability of generated hypothesis text. For personal assistant devices like Alexa, speech recognition errors are inevitable due to the growing number of applications. Hence, confidence scores provide an important metric to downstream consumers to gauge the correctness of ASR hypothesis text and

CSCML 20192019Continuous Key Agreement (CKA) is a two-party procedure used by Double Ratchet protocols (e. g., Signal). This is a continuous and synchronous protocol that generates a fresh key for every sent/received message. It guarantees forward secrecy and post-compromise security. Alwen et al. have recently proposed a new KEM-based CKA construction where every message contains a ciphertext and a fresh public key.

NAACL 20192019Neural network models have recently gained traction for sentence-level intent classification and token-based slot-label identification. In many real-world scenarios, users have multiple intents in the same utterance, and a tokenlevel slot label can belong to more than one intent. We investigate an attention-based neural network model that performs multi-label classification for identifying multiple intents
