mcfly 4.1.0

Deep learning for time series data

The goal of mcfly is to ease the use of deep learning technology for time series classification and regression. The advantage of deep learning is that it can handle raw data directly, without the need to compute signal features. Deep learning does not require expert domain knowledge about the data, and has been shown to be competitive with conventional machine learning techniques. As an example, you can apply mcfly on accelerometer data for activity classification, as shown in the tutorial.

Installation

Prerequisites:

• Python 3.10, 3.11
• pip
• Tensorflow 2, PyTorch or JAX

Installing all dependencies in separate conda environment:

conda env create -f environment.yml

# activate this new environment
source activate mcfly

To install the package, run one of the following commands in the project directory:

• pip install mcfly[tensorflow]
• pip install mcfly[torch]
• pip install mcfly[jax]

Please note: If you are not using tensorflow, you have to set the environment variable KERAS_BACKEND accordingly to your chosen backend.

For GPU support take a look at the latest version of the requirements section "most stable GPU environment" inside the Keras documentation or directly in their GitHub repository.

Visualization

We build a tool to visualize the configuration and performance of the models. The tool can be found on http://nlesc.github.io/mcfly/. To run the model visualization on your own computer, cd to the html directory and start up a python web server:

python -m http.server 8888 &

Navigate to http://localhost:8888/ in your browser to open the visualization. For a more elaborate description of the visualization see user manual.
