말뭉치

  1. One point to mention is that the gradient is stronger for tanh than sigmoid ( derivatives are steeper).[1]
  2. Deciding between the sigmoid or tanh will depend on your requirement of gradient strength.[1]
  3. Using a sigmoid or tanh will cause almost all neurons to fire in an analog way ( remember? ).[1]
  4. ReLu is less computationally expensive than tanh and sigmoid because it involves simpler mathematical operations.[1]
  5. This can be addressed by scaling the sigmoid function which is exactly what happens in the tanh function.[2]
  6. The gradient of the tanh function is steeper as compared to the sigmoid function.[2]
  7. Since only a certain number of neurons are activated, the ReLU function is far more computationally efficient when compared to the sigmoid and tanh function.[2]
  8. The hyperbolic tangent function, or tanh for short, is a similar shaped nonlinear activation function that outputs values between -1.0 and 1.0.[3]
  9. A general problem with both the sigmoid and tanh functions is that they saturate.[3]
  10. This means that large values snap to 1.0 and small values snap to -1 or 0 for tanh and sigmoid respectively.[3]
  11. Traditionally, LSTMs use the tanh activation function for the activation of the cell state and the sigmoid activation function for the node output.[3]
  12. Tanh function also knows as Tangent Hyperbolic function.[4]
  13. The tanh non-linearity is shown on the image above on the right.[5]
  14. Therefore, in practice the tanh non-linearity is always preferred to the sigmoid nonlinearity.[5]
  15. the convergence of stochastic gradient descent compared to the sigmoid/tanh functions.[5]
  16. The demo program illustrates three common neural network activation functions: logistic sigmoid, hyperbolic tangent and softmax.[6]
  17. The same inputs, weights and bias values yield outputs of 0.5006 and 0.5772 when the hyperbolic tangent activation function is used.[6]
  18. WriteLine("Computing outputs using Hyperbolic Tangent activation"); dnn.[6]
  19. The hyperbolic tangent function is often abbreviated as tanh.[6]
  20. It lags behind the Sigmoid and Tanh for some of the use cases.[7]
  21. Cons Tanh also has the vanishing gradient problem.[7]
  22. : (a) Activation functions compared the rectified linear units (ReLU), Sigmoid (“sigm”) and Tanh (“tanh”), Fig.[8]
  23. The only perk we will get using Tanh function is that the slope of function does not decrease quickly like sigmoid function.[9]
  24. Sigmoid activation function and Tanh activation function works terribly for the hidden layer.[9]
  25. Tanh: Hyperbolic tangent is an activation function similar to sigmoid but the output values range between -1 to 1.[10]
  26. Unlike sigmoid the output of Tanh function is zero centred, therefore Tanh is preferred more than sigmoid.[10]
  27. Arctangent: This activation function is similar to sigmoid and Tanh, it maps the inputs to outputs which range between (-2,2).[10]
  28. It somehow lags the sigmoid and Tanh for a few cases.[10]
  29. ReLU, Sigmoid and Tanh are today’s most widely used activation functions.[11]
  30. The results suggest that Tanh performs worse than ReLU and Sigmoid.[11]
  31. In my master’s thesis, I found that in some cases Tanh works better than ReLU.[11]
