This is the second article in the series about artificial neural networks. If you have not already done so, I recommend you read the first article, “Neural Networks: The Node“, before proceeding. It covers material that should be understood before attempting to tackle the topics presented here and in future articles in this series.

There are several properties that define the structure and functionality of neural networks: the network architecture, the learning paradigm, the learning rule, and the learning algorithm.

Rheo KneeHugh Herr, director of MIT’s Biomechatronics Group, has created the Rheo Knee, an artificial knee with an integrated microprocessor that both learns the user’s walking style and is able to quickly react and adapt to changes in terrain. The microprocessor calculates the position of the knee and the load on the limb 1000 times per second, continually learning the wearer’s gait and optimizing the proper resistance in the joint for each step.
