Speaker: Tanja Christina Kaeser Jacober (Stanford University) Title: Modeling and Individualizing Learning in Computer-Based Environments Abstract: Learning technologies are becoming increasingly important in today's education.

Predicting Topics in Scholarly Papers

by Announcements of talks＠IDSIA

Title: Predicting Topics in Scholarly Papers Time: 09:00 Location: Manno, Galleria 1, 2nd floor, room G-222 Speaker: Seyed Ali Bahrainian, PhD candidate, USI Abstract: In the last few decades, topic models have been extensively used to discover the latent topical structure of large text corpora; however, very little has been done to model the continuation of such topics in the near future. In this paper we present a novel approach for tracking topical changes over time and predicting the topics which would continue in the near future. For our experiments, we used a publicly available corpus of conference papers, since scholarly papers lead the technological advancements and represent an important source of information that can be used to make decisions regarding the funding strategies in the scientific community. The experimental results show that our model outperforms two major baselines for dynamic topic modeling in terms of predictive power.

PIDSIA Seminar by Jobst Landgrebe and Barry Smith, April 11th

by Announcements of talks＠IDSIA

*Speakers: Jobst Landgrebe and Barry Smith *Title: Ontology-Driven Automotive Repair Claims Management *Abstract: We are experiencing once again a period of enthusiasm in the AI research field, fired above all by the successes of the technology of deep neural networks or deep machine learning. In this talk we draw attention to what we take to be serious problems underlying current views of artificial intelligence encouraged by these successes, especially in the domain of language processing. We then show an alternative approach to language-centric AI, and illustrate this approach in relation to a specific example in the field of claims management. Summarized here: https://www.cognotekt.com/en/news/rechnungen-mit-ki-pruefen/ *Bios: - Jobst Landgrebe is owner and managing director of Cognotekt GmbH, a German company specializing in AI-based language processing applications - Barry Smith is Director of the (US) National Center for Ontological Research in Buffalo, NY and author of Building Ontologies with Basic Formal Ontology (MIT Press, 2015) *Date and Time: Thursday, 11th of April 2019, 12:00-13:00 *Location: Manno, Galleria 1, 2nd floor, room G1-201 *Doodle registration: Pizza and drinks will be offered at the end of the talk. If you plan to attend, please register in a timely fashion at the following link so that we will have no shortage of food: https://doodle.com/poll/8ukw2zqzsy83u995
