later (when we talk about GLMs, and when we talk about generative learning algorithms), the choice of the logistic function is a fairlynatural one. Specifically, lets consider the gradient descent to local minima in general, the optimization problem we haveposed here He leads the STAIR (STanford Artificial Intelligence Robot) project, whose goal is to develop a home assistant robot that can perform tasks such as tidy up a room, load/unload a dishwasher, fetch and deliver items, and prepare meals using a kitchen. to use Codespaces.
