Given a sequence of user interactions, the goal is to rank a list of hotels such that the topper the hotel in the list, the more likely that it will be clicked-out, as shown in the following figures. In the absence of neg-ative data, the above objective tries to rank all the positive items as highly as possible. These considerations include (1) LoadBalancing-studentsshouldnotbeover-burdenedwith too many requests; and (2) Expertise Matching -students. The theme of the ACM RecSys Challenge 2019 is to develop a session-based and context-aware recommender system using the dataset from Trivago, which is a global hotel search platform. To facilitate this task, we present domain-specific pre-trained word embeddings for the patent domain.

Crowdsourcing AI to solve real-world problems. 2M interactions with 50k playlists and 20k items. Recommender systems are ubiquitous on the Internet, lying at the heart of some of the most popular Internet services, including Net ix, Yahoo, and Amazon. The biggest mistake we can make is to assume that a user who has not clicked or rated an item necessarily dislikes that item. More specifically, it was curated via a longitudinal user study that involved a wearable sensor (Fitbit) and our custom mobile application called HealthyTogether. The overall goal of both scenarios is to detect abnormal behavior of a manufacturing machine based on the observation of the stream of measurements.
