MATLAB uses the scaled conjugate gradient algorithm (trainscg) as the default training function for autoencoders, which adapts its learning parameters dynamically during training, hence not having a fixed "default learning rate" in the traditional sense used in gradient descent-based algorithms. Wh...
Time series-based autoencoders can also be used to detect anomalies in signal data. For example, in predictive maintenance, an autoencoder can be trained on normal operating data from an industrial machine (Figure 5). Figure 5: Training on normal operating data for predictive maintenance. The ...
Hi, I train an autoencoder in matlab R2016a and I want to change some weights of encoder or decoder and flip them to zero or one, but by doing it, I saw this error"You cannot set the read-only property 'EncoderWeights' of Autoencoder.". I need to change the weights and consider ...

首先,需要一个数学工具,如matlab或octave。然后要理解BP神经网络什麼是BP神经网络呢?参考:http://tieba.baidu.com/p/2078195563BP神经网络的主要思想就是要通过迭代使cost function的值最小(分类效果最好),所谓cost function的主要成分就是使输出层与标准答案之间的差距。最终的cost function是所有训练集(或测试集)...
