1. Indeed, if the terms get large enough - greater than 1 - then we will no longer have a vanishing gradient problem.
2. Instead of a vanishing gradient problem, we'll have an exploding gradient problem.
3. The middle Tanh waveform provides ReLTanh with the ability of nonlinear fitting, and the linear parts contribute to the relief of vanishing gradient problem.
4. Theoretical proofs by mathematical derivations demonstrate that ReLTanh is available to diminish vanishing gradient problem and feasible to train thresholds.
5. The exploding and vanishing gradient problem has been the major conceptual principle behind most architecture and training improvements in recurrent neural networks (RNNs) during the last decade.
6. {The exploding and vanishing gradient problem has been the major conceptual principle behind most architecture and training improvements in recurrent neural networks (RNNs) during the last decade.
7. To model an algorithm that is good at capturing long-term dependencies, we need to focus on handling the vanishing gradient problem, as we will do in the upcoming sections of this blog post.
8. Now, we will see how during back propagation vanishing gradient problem occurs.
9. Therefore, it will also lead to vanishing gradient problem.
10. And even if this weight initialization technique is not employed, the vanishing gradient problem will most likely still occur.
11. Thus, with deep neural nets, the vanishing gradient problem becomes a major concern.
12. ReLUs still face the vanishing gradient problem, it’s just that they often face it to a lesser degree.
13. This is the problem of unstable gradients and is most popularly referred to as the vanishing gradient problem.
14. In general, the vanishing gradient problem is a problem that causes major difficulty when training a neural network.
15. One of the issues that had to be overcome in making them more useful and transitioning to modern deep learning networks was the vanishing gradient problem.
16. This post will examine the vanishing gradient problem, and demonstrate an improvement to the problem through the use of the rectified linear unit activation function, or ReLUs.
17. The vanishing gradient problem comes about in deep neural networks when the f' terms are all outputting values << 1.
18. However, even if the weights are initialized nicely, and the derivatives are sitting around the maximum i.e. ~0.2, with many layers there will still be a vanishing gradient problem.
19. The vanishing gradient problem requires us to use small learning rates with gradient descent which then needs many small steps to converge.
