Adopting LSTM memory units is a new best practice for recurrent neural networks for sequence prediction. In machine learning, the vanishing gradient problem is encountered when training artificial neural networks with gradient-based learning methods and backpropagation. VRNN (Jang et … Therefore, it is well known that stochastic gradient descent may only converge to a local minimum (and not a global minimum) for a neural network. In machine learning, the vanishing gradient problem is encountered when training artificial neural networks with gradient-based learning methods and backpropagation. 3. 8.7.1 illustrates the three strategies when analyzing the first few characters of The Time Machine book using backpropagation through time for RNNs:. While this issue should talk about "CPU ok but GPU gets nan." Vanilla RNN’s suffer from rapid gradient vanishing or gradient explosion. At an extreme, the values of weights can become so large as to overflow and result in NaN values.The explosion occurs through exponential growth by repeatedly multiplying gradients through the network layers that have values larger than 1 or vanishing occurs if the values are less than 1. Among the widespread examples of big data, the role of video streams from CCTV cameras is equally important as other sources like social media data, sensor data, agriculture data, medical data and data evolved from space research. 题主你好，LSTM只能避免RNN的梯度消失（gradient vanishing）；梯度膨胀(gradient explosion)不是个严重的问题，一般靠裁剪后的优化算法即可解决，比如gradient clipping（如果梯度的范数大于某个给定值，将梯度同比收缩）。下面简单说说LSTM如何避免梯度消失.
