Hi! I am Denis, Assistant Professor at the Department of Computer Science, in the School of Engineering at PUC Chile. I am also adjunct researcher at the Millennium Institute for Research on Fundamentals of Data. My research interests are Recommender Systems, Intelligent User Interfaces, and Information Visualization and I am currently leading the SocVis Research Lab.
If you are interested on these topics and want to work under my supervision as Master or PhD student, send me an e-mail to dparra[at]ing[dot]puc[dot]cl.

October 2018 I attended the ACM RecSys 2018 conference in Vancouver, Canada. We presented 2 papers in co-located workshops, one at RecSysKTL by del Río et al. "Do Better ImageNet Models Transfer Better … for Image Recommendation?"[paper][slides], and another one at the IntRS workshop by Dominguez et al. "Towards Explanations for Visual Recommender Systems of Artistic Images" [paper]

March 2018 I attended the ACM IUI 2018 conference in Tokyo, Japan. We had good news since the paper we wrote with my master student Ivania Donoso obtained a Best paper honorable mention. You can find the paper in the ACM DL or the pre-print directly here An Interactive Relevance Feedback Interface for Evidence-Based Health Care". At the end of March I will attend the ECIR conference in Grenoble.

January 2018 Our SocVis lab starts 2018 with three conference papers accepted. In EI, "CNVis: A Web-Based Visual Analytics Tool for Exploring Conference Navigator Data" in collaboration with professor Chaoli Wang from Notre Dame. In ACM IUI, the article "An Interactive Relevance Feedback Interface for Evidence-Based Health Care", which was the master's thesis project of my student Ivania Donoso. Finally, in ECIR "Learning to Leverage Microblog Information for QA Retrieval" by Jose Miguel Herrera, in collaboration with his advisor Prof. Barbara Poblete. Great start!

August 2017 I attended the ACM RecSys 2017 conference in Como, Italy. This was the first time I attended with my advised students, so it was a great experience! find some pictures here. We presented two posters in the main conference: pyRecLab: A Software Library for Quick Prototyping of Recommender Systems with Gabriel Sepulveda, Vicente Dominguez, and Towards a Recommender System for Undergraduate Research. with Felipe Del Rio, Jovan Kuzmicic, and Erick Svec. Moreover, we presented one poster in the Deep Learning for RecSys workshop, our work on artwork recommendation using visual features. I also presented a demo of the last version of Moodplay, a work we are doing with students Raimundo Herrera and Pablo Pino. Finally, I also co-organized the Large Scale RecSys (LSRS 2017) workshop, again a great experience!
