Enhancing efficiency of object recognition in different categorization levels by reinforcement learning in modular spiking neural networks

no code implementations10 Feb 2021 Fatemeh Sharifizadeh, Mohammad Ganjtabesh, Abbas Nowzari-Dalini

The human visual system contains a hierarchical sequence of modules that take part in visual perception at superordinate, basic, and subordinate categorization levels.

SpykeTorch: Efficient Simulation of Convolutional Spiking Neural Networks with at most one Spike per Neuron

1 code implementation6 Mar 2019 Milad Mozafari, Mohammad Ganjtabesh, Abbas Nowzari-Dalini, Timothée Masquelier

Application of deep convolutional spiking neural networks (SNNs) to artificial intelligence (AI) tasks has recently gained a lot of interest since SNNs are hardware-friendly and energy-efficient.

Bio-inspired digit recognition using reward-modulated spike-timing-dependent plasticity in deep convolutional networks

1 code implementation31 Mar 2018 Milad Mozafari, Mohammad Ganjtabesh, Abbas Nowzari-Dalini, Simon J. Thorpe, Timothée Masquelier

We trained it using a combination of spike-timing-dependent plasticity (STDP) for the lower layers and reward-modulated STDP (R-STDP) for the higher ones.

First-spike based visual categorization using reward-modulated STDP

no code implementations25 May 2017 Milad Mozafari, Saeed Reza Kheradpisheh, Timothée Masquelier, Abbas Nowzari-Dalini, Mohammad Ganjtabesh

In the highest layers, each neuron was assigned to an object category, and it was assumed that the stimulus category was the category of the first neuron to fire.

STDP-based spiking deep convolutional neural networks for object recognition

1 code implementation4 Nov 2016 Saeed Reza Kheradpisheh, Mohammad Ganjtabesh, Simon J. Thorpe, Timothée Masquelier

Coding was very sparse, with only a few thousands spikes per image, and in some cases the object category could be reasonably well inferred from the activity of a single higher-order neuron.

Humans and deep networks largely agree on which kinds of variation make object recognition harder

no code implementations21 Apr 2016 Saeed Reza Kheradpisheh, Masoud Ghodrati, Mohammad Ganjtabesh, Timothée Masquelier

This feed-forward architecture has inspired a new generation of bio-inspired computer vision systems called deep convolutional neural networks (DCNN), which are currently the best algorithms for object recognition in natural images.

Deep Networks Can Resemble Human Feed-forward Vision in Invariant Object Recognition

no code implementations17 Aug 2015 Saeed Reza Kheradpisheh, Masoud Ghodrati, Mohammad Ganjtabesh, Timothée Masquelier

Deep convolutional neural networks (DCNNs) have attracted much attention recently, and have shown to be able to recognize thousands of object categories in natural image databases.

Bio-inspired Unsupervised Learning of Visual Features Leads to Robust Invariant Object Recognition

no code implementations15 Apr 2015 Saeed Reza Kheradpisheh, Mohammad Ganjtabesh, Timothée Masquelier

Retinal image of surrounding objects varies tremendously due to the changes in position, size, pose, illumination condition, background context, occlusion, noise, and nonrigid deformations.
