Question

Write short notes on a) Weights b) Bias c) Learning rate and d) Threshold of ANN.​

Answer 1

Answer:

• Weight: In science and engineering, the weight of an object is the force acting on the object due to gravity. ... For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
• Bias: Bias is an irrational assumption or belief that warps the ability to make a decision based on facts and evidence. Equally, it is a tendency to ignore any evidence that does not line up with that assumption. A bias can be conscious or unconscious.
• learning rate: machine learning and statistics, the learning rate is a tuning parameter in an optimization algorithm that determines the step size at each iteration while moving toward a minimum of a loss function.
• Threshold of ANN:The idea of threshold was introduced into artificial neural network model [hereafter called Threshold-ANN model (T-ANN)] to represent the nonlinear characteristics of the runoff generation processes in the flood and non-flood periods
