Exactly what kind of calculations does a neuron perform? The activation function is calculated inside a neuron, and then a linear function (z = Wx + b) is computed. After calculating an activation function, a neuron uses the linear function z = Wx + b. A neuron "learns" a function g that linearly increases with input x (Wx + b). The average of all characteristics is calculated in a neuron, and then the result is fed into an activation function.

Consider a neuron with 3 inputs, 1 output, and a threshold (=0) activation function. If the two weights are w1 = 1, w2 = -1 and w3 = -1, and the bias is b = 1.5 (assuming the input to the bias is always +1), under which of the input below, the output will be 0?
Neurons compute? The activation function and the linear function, which is represented by the equation z = Wx + b, are both calculated by neurons. Both a linear function, represented by the equation z = Wx + b, and an activation function are computed by neurons. When g is present in a neuron, the input x is scaled linearly (Wx + b). Before using the result in an activation function, neurons perform a calculation to get the mean of all of their features.

The architecture of a neural network is provided. The input is a 3D feature vector, and the output is a 2D vector. The weights are also shown on the edges, connecting two nodes in two different layers. For each node in the 2 hidden layers and the output layer, a sigmoid function g() is used as an activation function. What are the equations for y1 and y2?
How do I understand that I am getting the correct output when using the sigmoid function in a neural network? Considering that a sigmoid function (activation function) helps with checking the value between 0.00001 to 1.Also, what does it mean if you get output that are around 0.999877 or 0.999955 or within those values? Do these values represent how accurate the neural net is?
The language must be in python. Neural Network Units weights of [-1.2, -1.1, 3.3, -2.1] two training examples:Example 1: [0.9, 10.0, 3.1, 1]Example 2: [0.9, 2.1, 3.7, 1] Note that you don't have to explicitly include a threshold or bias since the examples include a last element of 1 which means that the last weight effectively operates as a threshold. Create a single ReLU unit and provide the outputs for those examples.
