What is a recurrent neural network? A recurrent neural network or RNN is a deep neural network trained on sequential or time series data to create a machine learning (ML) model that can make sequential predictions or conclusions based on sequential inputs. An RNN might be used to predict ...
Keras is a deep learning library that enables us to build and train models efficiently. In the library, layers are connected to one another like pieces of Lego, resulting in a model that is clean and easy to understand. Model training is straightforward requiring only data, a number of ...
RNN-based is always not easy to learn 一般而言,你在做training的时候,你会希望,你的learning curve是像蓝色这条线,纵轴是total loss,横轴是epoch的数目,你会希望:随着epoch的增加,参数的不断update,loss会慢慢下降最后趋于收敛。但不幸的是,在训练RNN的时候,有时会看到这条绿色的线 我们分析下RNN的性质,看看...

Keras 是一个高级神经网络API,它封装了许多底层细节,使得构建和训练神经网络变得更加简单和直观。在Keras中,处理多层RNN(循环神经网络)通常不需要直接使用 MultiRNNCell。 1. 确认 MultiRNNCell 在Keras 3 中的可用性 MultiRNNCell 是TensorFlow 中用于堆叠多个 RNN 单元的低级API,而不是 Keras 的API。在 Keras ...
In multi-task learning, a single model is trained to perform several tasks at the same time. The model has a shared set of early layers that process the data in a common way, followed by separate layers for each specific task. This allows the model to learn general features that are use...
MMdnn is a set of tools to help users inter-operate among different deep learning frameworks. E.g. model conversion and visualization. Convert models between Caffe, Keras, MXNet, Tensorflow, CNTK, PyTorch Onnx and CoreML. - microsoft/MMdnn

Also, the "return_sequences=True" for each sample, will generate output from each LSTM cell for each timestep. This is typically fed into a second RNN layer, not into a regular Dense layer. Also, Keras should automatically infer the input data shape for every layer except the first. ...
Figure 5 - An RNN cell Repeated (Rolled-over) Tx Times We can verify this by the following lines of code: from keras.layers import Model, Input, LSTM Tx = 30 n_x = 3 n_s = 64 X = Input(shape=(Tx, n_x)) s, a, c = LSTM(n_s, return_sequences=True, return_state=True)...
