Programming a simple neural network
Though neural networks were considered to be of little use for a long time, the recent development of computing power and database size has proven otherwise. Since the revolution of machine learning in the last few years has been primarily driven by them, let’s dive right into the actual coding of neural nets. Before coding, it…
24. Reviews and Exercises
In this post are gathered the tutorials and exercises, called “mega-recitations”, to apply the concepts presented in the Artificial Intelligence course of Prof. Patrick Winston.
12b: Deep Neural Nets
Image recognition by a deep neural net Convolution: a neuron looks for patterns in a small portion (10×10 px) of an image (256×256 px), the process is repeated by moving this small area little by litte. Pooling: The result of the convolution is computed as a point for each portion analyzed. By a similar step…
12a: Neural Nets
Modeling biological neurons Neural nets are modeled upon real biological neurons, which have the following characteristics: All or none: the input from each entry in the neural net is either O or 1, the output is also 0 or 1 Cumulative influence: the influence of various input neurons accumulates to produce the final output result,…
