Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

In deep learning, given a multilayer perceptron, do weight matrices contain parameters to map values from a source layer (except for the input one) to a destination layer and do bias vectors contain parameters associated with destination layers only, (i.e. one bias vector per destination layer)?
What is the purpose of an activation function applied to an artificial neuron? -To add non-linear transformation to the neuron output -To rescale the output of the neuron -To normalize outputs of the neurons on a single hidden layer -To prepare output of the neuron for max/min/ave pooling -To perform batch normalization select one only
There are many sensors on a wind turbine, based on each sensor's reading many alerts are generated as (start, end). For easier monitoring, our customer is asking to raise alerts on the turbine level instead of on each sensor. If any sensor is having an alert, there should be an alert for the entire wind turbine. Suppose the alerts created with two sensors readings are [(0,3),(5,10),(1,4),(10,15)], then the turbine level alert should be [(0,4),(5,15)]. Return the alerts sorted by the start timestamp. If there is no alert from the sensor level, return an empty array []. Code needs to be in Python?
