kandi X-RAY | tensorflow-lstm-sin Summary
Single- and multilayer LSTM networks with no additional output nonlinearity based on aymericdamien's TensorFlow examples and Sequence prediction using recurrent neural networks. Experiments with varying numbers of hidden units, LSTM cells and techniques like gradient clipping were conducted using static_rnn and dynamic_rnn. All networks have been optimized using Adam on the MSE loss function.

QUESTION
I am experimenting with LSTMs in Keras with little to no luck. At some moment I decided to scale back to the most basic problems in order finally achieve some positive result.
However, even with simplest problems I find that Keras is unable to converge while the implementation of the same problem in Tensorflow gives stable result.
I am unwilling to just switch to Tensorflow without understanding why Keras keeps diverging on any problem I attempt.
My problem is a many-to-many sequence prediction of delayed sin echo, example below:
Blue line is a network input sequence, red dotted line is an expected output.
The experiment was inspired by this repo and workable Tensorflow solution was also created from it too.
The relevant excerpts from the my code are below, and full version of my minimal reproducible example is available here.

...ANSWER
Answered 2017-Oct-30 at 18:44Ok, I have managed to solve this. Keras implementation now converges steadily to a sensible solution too:
The models were in fact not identical. You may inspect with extra caution the Tensorflow
model version from the question and verify for yourself that actual Keras
equivalent is listed below, and isn't what stated in the question:

Install tensorflow-lstm-sin
You can use tensorflow-lstm-sin like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
