I have a master&#8217;s degree in Health Information Engineering from the University Carlos III of Madrid, with previous research experience in physics, neurobiology, chemistry, and mathematics. <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>I began university level research in high school, as I was selected for a gifted and talented program. At my undergraduate institution, the University of Kentucky, I received the highest merit-based scholarship and graduated with three bachelor degrees in 4 years: mathematics, chemistry, and Spanish. <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>In 2018, I joined two ongoing research groups in Madrid, Spain, one in psychiatry at the Jim\u00e9nez D\u00edaz Foundation and the other in machine learning at the University Carlos III of Madrid.<\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>I have multiple publications spanning the fields of mathematical number theory, psychiatry, and machine learning.

However, there is a presentation bias (users tend to click more on the first items in the list) and self-selection bias (users tend to rate more items they like than the ones they dislike) in play in the observed data which negatively impacts the performance of the recommender systems. The objective of the project is to use remote eye tracking to: <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>(1) model the users\u2019 consumption of the recommended items and their interaction with the recommender systems, <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>(2) debias the observed implicit feedback and <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>(3) improve existing offline and online evaluation methodologies. <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>From the eye tracking perspective, the challenge lies in the dynamic nature of the web interfaces where the recommendations are presented; content (targets) can change position over time or they can be overlayed by a different content; the project will therefore also contribute to the development of methods for mapping gaze to targets, while also accounting for the inaccuracies in the measurements that can arise from using eye tracking in an uncontrolled environment of the web.&nbsp;<\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>Expected Results: <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>1) Computational model of users\u2019 interaction with the recommender systems explicitly modeling positional, visual, and other biases by means of eye tracking; <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>(2) Evaluation methodology for recommender systems incorporating remote eye tracking; <\/p>\n<\/div>\n\n<div id=\"\" class=\"element core-paragraph\">\n<p>(3) Computational methods of the collected gaze data processing adapted for the dynamic nature of the web focusing on mapping the gaze to the correct targets (elements\/items on the webpage) and accounting for possible inaccuracies in the measurements<\/p>\n<\/div>\n\n<div id=\"projects\" class=\"element acf-loop\"><section id=\"projects\" class=\"loop old \" style=\"background-color: #ebf7f9;\" >\n\t<div class=\"wrapper-out\">\n\t\t<div class=\"wrapper-in\">\n\t\t\t<div class=\"in cf\">\n\t\t\t\t<div class=\"element-inner\">\n\t\t\t\t\t<div class=\"headline\"><h2>Projects<\/h2><\/div>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"loop-wrap loop-Project loop-style1 loop-load_more loop-2 cf\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<article id=\"loop-item-22229\" class=\"loop-item\">\n\t\t\t\t\t\t\t\t\t<div class=\"inner cf\">\n\t\t\t\t\t\t\t\t\t\t<a href=\"https:\/\/kinit.sk\/sk\/projekt\/eyes4icu-eyes-for-information-communication-and-understanding\/\">\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"picture\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"320\" height=\"200\" data-src=\"https:\/\/kinit.sk\/wp-content\/uploads\/2022\/07\/202207_web_project_eyes4icu_horizoneu-320x200.jpg\" class=\"attachment-thumbnail size-thumbnail wp-post-image lazyload\" alt=\"\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 320px; --smush-placeholder-aspect-ratio: 320\/200;\" \/>\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"content cf\">\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"content-inner\">\n\t\t\t\t\t\t\t\t\t\t\t\t<h3>Eyes4ICU: Eyes for Information, Communication and Understanding<\/h3>\n                        \t\t\t\t\t\t\t\t\t\t\t\t<div class=\"meta cf\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"date\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\tj\u00fal 8. 2022\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"excerpt\">Eyes4ICU is a Marie-Sk\u0142odowska-Curie Doctoral Network within the Horizon Europe program.
