Facebook AI is pleased to invite university faculty to respond to this call for proposals about machine learning on graph data for interpretable personalized recommendation.
At Facebook we are looking to provide users with great experiences in terms of providing highly relevant content, capturing the niche, and truly personal interests and contextual preferences, and being intuitive and interpretable for user agency to control what they see.
We aim to develop a broader and deeper understanding across the industry of how to personalize user experience. We are building the next generation of ML modeling and platform technology centered around people and are committed to driving this innovation forward in an interpretable and trustworthy manner. To model users’ interest in a comprehensive way, we hope to leverage recent advances in machine learning on graph data, where various modeling techniques can be jointly built over a unified graph that organizes all the relevant entities and interactions.
Facebook AI is soliciting proposals to help accelerate research that targets our next personalized recommendation for better capturing users interest and fulfilling high level purposes in an interpretable and trustworthy approach, with focus on techniques of machine learning on graph. We hope to work with researchers to influence how we build our products, and bring values to our users and the whole society.
Up to two proposals will be selected, for projects at a cost of up to $75,000 each. Payment will be made to the Principal Investigator’s host university in the form of a sponsored research agreement with Facebook per the Terms and Conditions set forth below. We strongly encourage researchers from diverse backgrounds and of diverse abilities to apply.
Deadline for submissions are on March 15, 11:59pm PT.
Many highly impactful products pertaining to FB embrace a strong connectivity to users and their engaged items. From the machine learning perspective, it implies there is a user-centric contextual graph underlying various input data and models, motivating us to explore such a graph for decoding user interests and making personalized recommendations accordingly. Despite the remarkable progress in personalization, a fundamental question remains nascent: how can we make the personalized learning process and results be explainable, transparent, and fair? The answer to this question benefits a variety of our products for user experience and facilitates trustworthy interaction with users. Therefore, the research objective of this project is to explore the power and beauty of such user-centric contextual graphs on applications interesting to FB, with areas of interest that include, but are not limited to, the following:
1. Improving interest-based relevance in personalized recommendation
How to leverage contextual graph capture users’ niche and truly personal interests and contextual preferences?
How to optimize the usage of user interest-related data through a graph with heterogeneous entities/links, as such data are usually scattered and unstructured in practice?
How to effectively model user interest using a graph based approach from various heterogeneous sources and to capture the dynamics (interest changes with respect to time variance, seasonality, location, context, and evolves over time)?
How to improve cold start and make fast interest profiling for new users/creators introduced to a contextual graph?
How to improve the freshness (i.e. newly emerging contents) and democracy (i.e. not dominated by social celebrities or a few highly active creators)
2. Improving the understanding of users’ interest through ML modeling techniques
How to make the personalized recommendation intuitive and interpretable to our users, and give user agency to control what they see?
How to incorporate desired new angles for the interest representation using a graph based approach, such as explicitness, explainability, context-awareness and dynamics?
How to shift recommendation from who and what to how and why, leveraging a variety of sources, factors and interactions that can be represented by a heterogenous graph in a unified way?
How to address filter bubbles in personalized recommendation, such as to improve the balance between interest diversity (exploration) and exploitation?
How to bring up diversity and exploration into new topics/interests when relevant entities/factors are linked as a graph?
3. Optimizing user cohort characterization
How to leverage contextual graph and user cohort analysis to mitigate various unwanted biases in recommendation?
How to design efficient large scale graph clustering algorithms to model collective user segments in the use case of user cohort analysis, for industrialized recommendation applications?
How to improve hierarchical clustering for user-interest based recommendation and explore different interest granularity levels for sourcing and ranking?
