Hi

I am David Corvoysier, versatile developer and open Source enthusiast.

It’s been quite a while since HTML5 video was introduced, and Adobe and Microsoft have stopped promoting Flash and Silverlight since early 2011, but it is only since a few days that the first HTML5 based commercial video service has been launched.

Why did it take so long ? Well, there were surely a few hurdles to overcome, but only one was really a show-stopper …

Identify Repeating Patterns using Spiking Neural Networks in Tensorflow

26 Jul 2018 by David Corvoysier

Spiking neural networks (SNN) are the 3rd generation of neural networks.

SNN do not react on each stimulus, but rather accumulate inputs until they reach a threshold potential and generate a ‘spike’.

Because of their very nature, SNNs cannot be trained like 2nd generation neural networks using gradient descent.

Spike Timing Dependent Plasticity (STDP) is a biological process that inspired an unsupervised training method for SNNs.

In this article, I will provide an illustration of how STDP can be used to teach a single neuron to identify a repeating pattern in a continuous stream of input spikes.

Leaky Integrate and Fire neuron with Tensorflow

Spiking Neural Networks (SNN) are the next generation of neural networks, that operate using spikes, which are discrete events that take place at points in time, rather than continuous values.

Essentially, once a stimulated neuron reaches a certain potential, it spikes, and the potential of that neuron is reset.

In this article, I will detail how the Leaky Integrate and Fire (LIF) spiking neuron model can be implemented using Tensorflow.

Simulating spiking neurons with Tensorflow

24 Jul 2018 by David Corvoysier

Spiking Neural Networks are the next generation of machine learning, according to the litterature.

After the feed-forward perceptrons of the last century and the bi-directional deep networks trained using gradient descent of today, this 3rd generation of neural networks uses biologically-realistic models of neurons to carry out computation.

A spiking neural network (SNN) operates using spikes, which are discrete events that take place at points in time, rather than continuous values. The occurrence of a spike is determined by differential equations that represent the membrane potential of the neuron. Essentially, once a neuron reaches a certain potential, it spikes, and the potential of that neuron is reset.

In this article, I will detail how this kind of network can be modelled using Tensorflow.
