<jupyter_start><jupyter_text>Some common activation functions* signmoid function* hyperbolic tangent function The hyperbolic tangent function `tanh(x)` is actually `sinh(x)` divided by `cosh(x)`. It is represented in graph in the following way<jupyter_code>import numpy as np
x = np.arange(-1000, 1000, 0.001)
x
y = np.tanh(x)
import matplotlib.pyplot as plt
plt.plot(x, y)
plt.xlim(-10,10)
plt.ylim(-1,1)
plt.title('tanh function')
plt.xlabel('x')
plt.ylabel('tanh(x)')<jupyter_output><empty_output>
