Unsupervised visual discrimination learning of complex stimuli: Accuracy, bias and generalization
Through same-different judgements, we can discriminate an immense variety of stimuli and consequently, they are critical in our everyday interaction with the environment. The quality of the judgements depends on familiarity ...
Statistical learning approaches for discriminant features selection
(Sociedade Brasileira de Computação, 2008)
Supervised statistical learning covers important models like Support Vector Machines (SVM) and Linear Discriminant Analysis (LDA). In this paper we describe the idea of using the discriminant weights given by SVM and LDA ...

Model selection for discriminative restricted boltzmann machines through meta-heuristic techniques
Discriminative learning of Restricted Boltzmann Machines has been recently introduced as an alternative to provide a self-contained approach for both unsupervised feature learning and classification purposes. However, one ...
Ensino de relações nome-objeto e aprendizagem de relações emergentes por bebês
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em PsicologiaCâmpus São Carlos, 2018-04-30)
The studies reported in this dissertation specifically addressed the population of toddlers, aged between 14 and 25 months age. The studies investigated the teaching of name-object relations in tasks of auditory-visual ...
Rats can learn a roughness discrimination using only their vibrissal system
Rats learned to discriminate between two degrees of roughness, detecting the stimuli only with their vibrissal system. After bilateral trimming of the vibrissae, performance abruptly dropped to chance levels and remained ...
Procedimentos e processos uma delicada relação na aprendizagem de discriminações por bebês
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Psicologia, 2013-08-30)
This dissertation was based on four empirical research reports submitted for publication in specialized journals. The empirical researches laid the foundations for a theoretical analysis on Stimulus Control and discrimination ...
Associative learning in the multichamber tank: a new learning paradigm for zebrafish
Occasion setting in Pavlovian ambiguous target discriminations
(ELSEVIER SCIENCE BV, 2008)
Rats were trained in a Pavlovian serial ambiguous target discrimination, in which a target cue was reinforced if it was preceded by one stimulus (P -> T+) but was not reinforced if it was preceded by another stimulus (N ...
Clinical feasibility of cognitive testing in dogs (Canis lupus familiaris)
(Elsevier B.V., 2014-01-01)
Several cognitive tests have been developed to evaluate specific aspects of human and animal learning and memory. These tests have been used for early detection of cognitive deficits and to monitor the treatment of dogs ...
