  This study has the following objectives: 1) To develop a system for screening patients that will accurately detect cases of diabetic retinopathy through dilated eye examination – The system will be used as an automated retinopathy classification system, distinguishing between normal images (patients who do not require further attention) and images suggestive of retinopathy (patients who r…

  In this work, we investigate the recently formalised inner alignment problem. In broad terms, to align an artificial intelligence is to construct or adjust it in such a way that its outputs are in accordance with human preferences. Internal alignment is a subtask within this exercise, in which the system is treated as an optimisation mechanism which is in turn optimised by some other opti…

  The main goal of this project is to build a system that receives a description of a trafficnetwork and returns an optimal policy for the traffic flow control in the region. To achieve this goal the system puts together algorithms from two well developed areas in Artificial Intelligence: probabilistic planning and virtual crowds. Although both areas present good algorithms their use is lim…

• Abstract

  I will develop two lines of research, both using large datasets on education outcomes, in particular the PISA exam (for primary education) dataset and the Brazilian ENADE exam (for higher education) dataset. The first project is to evaluate an hypothesis I raised in the paper Wainer,Vieira & Melguizo 2015 that at as time passes (or systems become better or society learns how to use comput…
