In this paper, we study the applicability of active learning (AL) in operative scenarios. More particularly, we consider the well-known contradiction between the AL heuristics, which rank the pixels according to their uncertainty, and the user's confidence ...
We present an eye-tracking study to compare different modalities for visual augmentations of the teacher’s explicit deictic gestures on a video lecture. We compared three visualizations: 1) hand gestures with a pointer, 2) gaze overlay, and 3) no-augmentat ...
We study the problem of actively learning a multi-index function of the form f (x) = g_0 (A_0 x) from its point evaluations, where A_0 ∈ R_{k×d} with k ≪ d. We build on the assumptions and techniques of an existing approach based on low-rank matrix recover ...
An article reporting statistical evidence for epigenetic transfer of learned behavior has important implications, if true. With random sampling, real effects do not always result in rejection of the null hypothesis, but the reported experiments were unifor ...
In the last few years, active learning has been gaining growing interest in the remote sensing community in optimizing the process of training sample collection for supervised image classification. Current strategies formulate the active learning problem i ...
When dealing with supervised target detection, the acquisition of labeled samples is one of the most critical phases: the samples must be yet representative of the class of interest, but must also be found among a vast majority of non-target examples. More ...
This paper presents how platforms initially designed to enable the construction of personal learning environments can help teachers and learners to aggregate their own MOOCs from resources freely available in the Cloud under Creative Commons licenses. Comp ...
This thesis concerns the observation and modeling of solute transport processes, focusing in particular on the theoretical formulation by means of travel and residence time distributions. The work reports and analyzes data collected from a controlled exper ...
Can we predict students attention from a classroom video? We present our system for analysing movement of students in classroom during a lecture. We go into details about the technical side for analysing motion of people with limited visibility, and we pre ...
In this poster and demo, we showcase a new class of problems that can occur due to inconsistent packet processing at an OpenFlow controller. We proceed to outline a potential solution. ...
