Mix-and-Match: Scalable Dialog Response Retrieval using Gaussian Mixture Embeddings
Gaurav Pandey, Danish Contractor, Sachindra Joshi
Embedding-based approaches for dialog response retrieval embed the context-response pairs as points in the embedding space. These approaches are scalable, but fail to account for t…
Simulated Chats for Building Dialog Systems: Learning to Generate Conversations from Instructions
Biswesh Mohapatra, Gaurav Pandey, Danish Contractor +1
Popular dialog datasets such as MultiWOZ are created by providing crowd workers an instruction, expressed in natural language, that describes the task to be accomplished. Crowd wor…
Unsupervised feature learning with discriminative encoder
Gaurav Pandey, Ambedkar Dukkipati
In recent years, deep discriminative models have achieved extraordinary performance on supervised learning tasks, significantly outperforming their generative counterparts. However…
Discriminative Neural Topic Models
Gaurav Pandey, Ambedkar Dukkipati
We propose a neural network based approach for learning topics from text and image datasets. The model makes no assumptions about the conditional distribution of the observed featu…
