Perceptron Learning and Classification in a Modeled Cortical Pyramidal Cell

The Dendritic Density Field of a Cortical Pyramidal Cell

Much is known about the computation in individual neurons in the cortical column. Also, the selective connectivity between many cortical neuron types has been studied in great detail. However, due to the complexity of this microcircuitry its functional role within the cortical column remains a mystery. Some of the wiring behavior between neurons can be interpreted directly from their particular...

Online Classification : Perceptron and Winnow

In this lecture we will start to study the online learning setting that was discussed briefly in the first lecture. Unlike the batch setting we have studied so far, where one is given a sample or ‘batch’ of training data and the goal is to learn from this data a model that can make accurate predictions in the future, in the online setting, learning takes place in a sequence of trials: on each t...

Synaptic Integration Gradients in Single Cortical Pyramidal Cell Dendrites

Cortical pyramidal neurons receive thousands of synaptic inputs arriving at different dendritic locations with varying degrees of temporal synchrony. It is not known if different locations along single cortical dendrites integrate excitatory inputs in different ways. Here we have used two-photon glutamate uncaging and compartmental modeling to reveal a gradient of nonlinear synaptic integration...

An evolutive architecture coupled with optimal perceptron learning for classification

the relationship between iranian efl learners beliefs about rote learning, their use of vocabulary learning strategies and their success in vocabulary learning: a think-aloud protocol study

the purpose of this study was to investigate iranian efl learners’ beliefs about the role of rote learning (rl) in vocabulary learning strategies; besides, the study examined if english proficiency would influence learners’ vocabulary learning strategy use. this study addresses the need for a clear understanding of the role of rl in efl vocabulary learning by looking at iranian efl learners’ ow...
