Project: Introduction Of The Forward Forward Method By Geoffrey Hilton

Here’s a nice video about interview of Geoffrey Hilton on his new Forwarad Forward algorithm, which I am currently working on based on his preliminary research. This interview is pretty cool as it shows us how a great idea was generated: thousands of times of trying, large amount of reading, consistent curiosity and explorations… and also hard working.

Project: Memory And Nonlinearity In Reservoir Computing

When talking about reservoir computing, one must mention that the reservoir’s main requirements are nonlinearity and a memory effect, also known as the ‘echo state property’ in the context of Echo State Networks (see more in one of my other blog: (What is and why reservoir computing). But why it isn’t a system has certain memory effect must also have nonlinearity? Intuitively, Nonlinear systems often exhibit complex behaviors that are sensitive to initial conditions, such as chaos. Since memory effects introduce a form of complexity— where the output depends not just on the current input but also on past inputs— it can be easy to conflate this complexity with nonlinearity.
