QONFEST 20202020The timed position of documents retrieved by learning to rank models can be seen as signals. Signals carry useful information such as drop or rise of documents over time or user behaviors. In this work, we propose to use the logic formalism called Signal Temporal Logic (STL) to characterize document behaviors in ranking accordingly to the specified formulas. Our analysis shows that interesting document

Interspeech 20202020We present UTACO, a singing synthesis model based on an attention-based sequence-to-sequence mechanism and a vocoder based on dilated causal convolutions. These two classes of models have significantly affected the field of text-to-speech, but have never been thoroughly applied to the task of singing synthesis. UTACO demonstrates that attention can be successfully applied to the singing synthesis field

EMNLP 20202020In natural language, often multiple entities appear in the same text. However, most previous works in Relation Extraction (RE) limit the scope to identifying the relation between two entities at a time. Such an approach induces a quadratic computation time, and also overlooks the interdependency between multiple relations, namely the relation of relations (RoR). Due to the significance of RoR in existing

FMCAD 20202020In practice, few security bugs found in source code are urgent, but quickly identifying which ones are is hard. We describe the application of bounded model checking to triaging reported issues quickly at the cloud service provider Amazon Web Services (AWS). We focus on the job of reactive security experts who need to determine the severity of bugs found in the Xen hypervisor. We show that, using our publicly

RecSys 2020 Workshop on Online Recommender Systems and User Modeling2020Classical approaches to recommendation systems like collaborative filtering learn a static model given the user historic interaction data. These approaches do not perform well in dynamic environments where the sets of users and items are continually changing. Users convey their preferences implicitly by providing feedback in the form of clicks, views and ratings, as they interact with the system. Utilizing
