print("Hello World!")
Here is an example of a Python script from the Github Hacksofteare repository:
import numpy as np
def sigmoid(x):
return 1 / (1 + np.exp(-x))
def predict(parameters, X):
A = X
for i in range(1, len(parameters) // 2):
A_prev = A
W = parameters['W' + str(i)]
b = parameters['b' + str(i)]
Z = np.dot(W, A_prev) + b
A = sigmoid(Z)
W = parameters['W' + str(len(parameters)//2)]
b = parameters['b' + str(len(parameters)//2)]
Z = np.dot(W, A) + b
return sigmoid(Z)
parameters = {
'W1': np.array([[-0.01973458, -0.43753406],
[-0.19745192, 0.24969783]]),
'b1': np.array([[-0.12477469],
[ 0.2571196 ]]),
'W2': np.array([[-0.15552471, 0.48447399]]),
'b2': np.array([[-0.93002948]])
}
X = np.array([[1.96483459, 2.55408887]])
result = predict(parameters, X)
print(result)
This script demonstrates the use of a sigmoid function to predict an output from input data. By studying and modifying examples like this one, you can improve your Python programming skills and gain a deeper understanding of important concepts and techniques.
