I have a tibial stress fracture from running and was told to use crutches for three weeks. In general, is this really necessary once the pain has subsided (as it has, in my case). Feels silly to use crutches when nothing hurts.
An artificial neuron network (ANN) is a computational model based on the structure and functions of biological neural networks. Information that flows through the network affects the structure of the ANN because a neural network changes - or learns, in a sense - based on that input and output. ANNs are considered nonlinear statistical data modeling tools where the complex relationships between inputs and outputs are modeled or patterns are found.
Annotating is a fancy word for note-taking on the text, and it is a way to slow down the reading process and to help you engage with a work so that you better understand it. Some students don't annotate because they want to read for pleasure only.
