Strategy development and learning differences in supervised and unsupervised categorization.
The processes that determine unsupervised categorization, the task of classifying stimuli without guidance or feedback, are poorly understood. Two experiments examined the emergence and plasticity of unsupervised strategies using perceptual stimuli that varied along two separable dimensions. In the first experiment, participants either classified stimuli into any two categories of their choice ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولCategorization, Recognition, and Unsupervised Learning
In this chapter, we review several strands of research that share one common theme: the close conceptual and empirical links between categorization and recognition memory. We demonstrate that these links are strong, and often surprising. We explore the relation between recognition and unsupervised learning, and we investigate how perceptual processes can provide a unifying link between categori...
متن کاملAdaptive categorization in unsupervised learning.
In 3 experiments, the authors provide evidence for a distinct category-invention process in unsupervised (discovery) learning and set forth a method for observing and investigating that process. In the 1st 2 experiments, the sequencing of unlabeled training instances strongly affected participants' ability to discover patterns (categories) across those instances. In the 3rd experiment, providin...
متن کاملSupervised and unsupervised learning in phonetic adaptation
Speech perception requires ongoing perceptual category learning. Each talker speaks differently, and listeners need to learn each talker’s particular acoustic cue distributions in order to comprehend speech robustly from multiple talkers. This phonetic adaptation is a semi-supervised learning problem, because sometimes a particular cue value occurs with information that labels the talker’s inte...
