Learning to Match Using Local and Distributed Representations of Text for Web Search
Bhaskar Mitra, Fernando Diaz, Nick Craswell
Models such as latent semantic analysis and those based on neural embeddings learn distributed representations of text, and match the query against the document in the latent seman…
The Social Dynamics of Language Change in Online Networks
Rahul Goel, Sandeep Soni, Naman Goyal +4
Language change is a complex social phenomenon, revealing pathways of communication and sociocultural influence. But, while language change has long been a topic of study in sociol…
Query Expansion with Locally-Trained Word Embeddings
Fernando Diaz, Bhaskar Mitra, Nick Craswell
Continuous space word embeddings have received a great deal of attention in the natural language processing and machine learning communities for their ability to model term similar…
Real-Time Web Scale Event Summarization Using Sequential Decision Making
Chris Kedzie, Fernando Diaz, Kathleen McKeown
We present a system based on sequential decision making for the online summarization of massive document streams, such as those found on the web. Given an event of interest (e.g. "…
Exploratory Gradient Boosting for Reinforcement Learning in Complex Domains
David Abel, Alekh Agarwal, Fernando Diaz +2
High-dimensional observations and complex real-world dynamics present major challenges in reinforcement learning for both function approximation and exploration. We address both of…
