Deep Learning for Cryptocurrency Price Prediction Introduction This repo makes use of the state-of-art Deep Learning algorithm to predict the price of Bitcoin, which has the potential to generalize to other cryptocurrency. It leverages models such as CNN and RNN implemented by Keras running on top of Tensorflow. You can find more detailed illustration in this blog post.

Deep Learning for Cryptocurrency Price Prediction
Introduction
This repo makes use of the state-of-art Deep Learning algorithm to predict the price of Bitcoin, which has the potential to generalize to other cryptocurrency. It leverages models such as CNN and RNN implemented by Keras running on top of Tensorflow. You can find more detailed illustration in this blog post.
Getting Started
To run this repo, be sure to install the following environment and library:
Data is collected from poloniex and parse to h5py file:
DataCollection.ipynb
PastSampler.ipynb
Run
To run the prediction model, select one of the model. For instance,
python CNN.py
To run iPython file, you need to run jupyter notebook
jupyter notebook
Be sure to run DataCollection.ipynb and PastSampler.ipynb first to create database for training models.
Input & Output & Loss
The input consists of a list of past Bitcoin data with step size of 256.
The output is the predicted value of the future data with step size of 16. Note that since the data is ticked every five minutes, the input data spans over the past 1280 minutes, while the output cover the future 80 minutes. The datas are scaled with MinMaxScaler provided by sklearn over the entire dataset. The loss is defined as Mean Square Error (MSE).
