Are you an AI expert, or are you planning to be? There are three fundamental challenges that will underlie the major AI evolutions over the next decade. These are the three areas where you NEED to understand the fundamentals – before AI moves so fast that you’ll never catch up. Let them guide your deep study for the year ahead. Check them out in this new YouTube post: Live free or die, my friend – AJ Maren Live free or…
Chapter 7: Energy-Based Neural Networks This is the full chapter draft from the book-in-progress, Statistical Mechanics, Neural Networks, and Artificial Intelligence. This chapter draft covers not only the Hopfield neural network (released as an excerpt last week), but also the Boltzmann machine, in both general and restricted forms. It deals with that form-equals-function connection, based on the energy equation. (However, we postpone the full-fledged learning method to a later chapter.)

Working Through Salakhutdinov and Hinton’s “An Efficient Learning Procedure for Deep Boltzmann Machines” We can accomplish a lot, using multiple layers trained with backpropagation. However (as we all know), there are limits to how many layers that we can train at once, if we’re relying strictly on backpropagation (or any other gradient-descent learning rule). This is what stalled out the neural networks community, from the mid-1990’s to the mid-2000’s. The breakthrough came from Hinton and his group, with a…
Putting It Into Practice: If we’re going to move our neural network-type architectures into a new, more powerful realm of AI capability, we need to bust out of the “sausage-making” mentality that has governed them thus far, as we discussed last week. To do this, we need to give our hidden layer(s) something to do besides respond to input stimulus. It’s very realistic that this “something” should be free energy minimization, because that’s one of the strongest principles in the…
