Video Processing by Neural Networks

Check out these links where there is some success in processing video with neural networks using a Convolutional Neural Network (CNN) followed by a Recursive Neural Network (RNN) using LSTM’s (Long Short-term Memory) modules.

Computer go faster – GPU’s

Some machine learning or deep learning data sets can take a lot of CPU time, their doing a lot of matrix arithmetic operations. There is a lot of number crunching here.

If you want to write code for GPUs then I suggest you to try the following Udacity course. Introduction to Parallel Programming With CUDA

So the abbreviations are crazy, CPU stands for central processing unit,  GPU means graphics processing unit.  What is more crazy is that almost all computers have a CPU and a GPU. The CPU does almost all computing to run the various applications (programs) on the computer. The GPU runs the graphics card, but not all GPU’s are easy to use for math calculations beside its graphics.

Then Google is working on a variety of custom machine learning chips that are even faster.

Convolutional Neural Networks

Convolutional Neural Networks got inspired from the way our human visual cortex works (human eye) and classifies images like dog, cat, man, women, car, jet, or computer.
Convolutional Neural Networks are used for the classification of images.They do a great job because the training of the neural network breaks up the image into component parts and does classification based on various parts of the image. So a dog or cat or numerical number is learned by the various properties of the image. Here are some great links:

Music — Artificial Intelligence

wow, look at the ability for Machine Learning and Artificial Intelligence to learn your music rhythm and melody and play a duet on it.

Try it: Here!    How does it work: Here!

It is here based on Google’s TensorFlow Machine Learning open source software.  Check out this link about “Make Music and Art Using Machine Learning” at magenta.tensorflow.org   Then look at Learning from A.I. Duet .  Some real possibilities for expanding music and allowing software to help accompany the musician.  Yes this will not make one a better musician, but it sure helps to make more music.  The software is part of the work of the Google Brain team who work on Magenta project in collaboration with the Google Creative Lab team.

Now to take this to the next level, consider this note on

Artificial Intelligence – notes

With machine learning, Neural Networks are looking promising for deep learning. But there is the rise of Bayesians, which is researchers doing Artificial Intelligence (AI) through the scientific method starting with an hypothesis. There is lots of trial and error designing a Neural Network, lots of parameters to tweak as one tries to get the data to correlate. Can machine learning and neural networks help us design better neural networks?

Creativity and more…

To be creative, one must start somewhere. Creativity is bringing things together. But just brain-storm and consider things even outside the box, things that are impossible to achieve (so we think).  Try a different mathematical solution, a different marketing or engineering solution.  Success sometimes comes by just tweaking things just a little.

Consider the configuration of artificial intelligence and deep learning neural networks. There are so many ways to configure and initialize them.  So many different types of neural nodes and ways to mathematically connect the nodes also called Perceptrons.

Here is a great set of project results to consider for stimulating creativity in Machine Learning…
