The Priberam Machine Learning Lunch Seminars are a series of informal meetings which occur every two weeks at Instituto Superior Técnico, in Lisbon. It works as a discussion forum involving different research groups, from IST and elsewhere. Its participants are interested in areas such as (but not limited to): statistical machine learning, signal processing, pattern recognition, computer vision, natural language processing, computational biology, neural networks, control systems, reinforcement learning, or anything related (even if vaguely) with machine learning.

The seminars last for about one hour (including time for discussion and questions) and revolve around the general topic of Machine Learning. The speaker is a volunteer who decides the topic of her presentation. Past seminars have included presentations about state-of-the-art research, surveys and tutorials, practicing a conference talk, presenting a challenging problem and asking for help, and illustrating an interesting application of Machine Learning such as a prototype or finished product.

Presenters can have any background: undergrads, graduate students, academic researchers, company staff, etc. Anyone is welcome both to attend the seminar as well as to present it. Ocasionally we will have invited speakers. See below for a list of all seminars, including the speakers, titles and abstracts.

Note: The seminars are held at lunch-time, and include delicious free food.

Feel free to join our mailing list, where seminar topics are announced beforehand. You may also visit the mailing list webpage. Anyone can attend the seminars; no registration is necessary. If you would like to present something, please send us an email.

The seminars are usually held every other Tuesday, from 1 PM to 2 PM, at the IST campus in Alameda. This sometimes changes due to availability of the speakers, so check regularly!

Video Summaries for Science Talks

Anfiteatro do Complexo Interdisciplinar

Instituto Superior Técnico - Alameda


Scientific talks range from conference presentations to lectures and documentaries. Even though some formats have high-grade content, such as lectures, their presentation is not always the most appealing. On the other hand, documentaries and other entertainment-driven programs can present consolidated information benefiting from aesthetically assured visual and audible effects. Motivated by these aspects, we illustrate the topics of a physics lecture through the use of documentaries. Our main concerns are the process of content selection and coherence aspects. The creation process uses a summarized transcript of a physics lecture to select topic-related content from a collection of documentaries. The issue of coherence is addressed as a consequence of the content selection process, as well as by means of video composition techniques via content organization.


Bio: Paulo Figueiredo received both his MSc (2015) and BSc (2013) degree in Information Systems and Computer Engineering from Instituto Superior Técnico (IST), Lisbon, Portugal. His MSc thesis, entitled “Video Summaries for Science Talks”, was done in collaboration with the Spoken Language Systems (L2F) of INESC-ID advised by professor David Martins de Matos and Ricardo Ribeiro. Recently, he published “Summarization of films and documentaries based on subtitles and scripts” in Elsevier’s Pattern Recognition Letters.
