Learn What NOT to Learn: Towards Generative Safety in Chatbots

no code implementations21 Apr 2023 Leila Khalatbari, Yejin Bang, Dan Su, Willy Chung, Saeed Ghadimi, Hossein Sameti, Pascale Fung

Our approach differs from the standard contrastive learning framework in that it automatically obtains positive and negative signals from the safe and unsafe language distributions that have been learned beforehand.

Speaker Recognition with Random Digit Strings Using Uncertainty Normalized HMM-based i-vectors

no code implementations13 Jul 2019 Nooshin Maghsoodi, Hossein Sameti, Hossein Zeinali, Themos~Stafylakis

By making use of the natural partition of input features into digits, we train digit-specific i-vector extractors on top of each HMM and we extract well-localized i-vectors, each modelling merely the phonetic content corresponding to a single digit.
