WearableSensorData

This repository provides the codes and data used in our paper "Human Activity Recognition Based on Wearable Sensor Data: A Standardization of the State-of-the-Art", where we implement and evaluate several state-of-the-art approaches, ranging from handcrafted-based methods to convolutional neural networks. Also, we standardize a large number of datasets, which vary in terms of sampling rate, number of sensors, activities, and subjects.

Requirements

Quick Start

  1. Clone this repository
  2. Run 
    python <Catal2015|...|ChenXue2015>.py data/<SNOW|FNOW|LOTO|LOSO>/<MHEALTH|USCHAD|UTD-MHAD1_1s|UTD-MHAD2_1s|WHARF|WISDM>.npz

    For example

    python Catal2015.py data/LOSO/MHEALTH.npz

Data Format

The raw signal provided by the original dataset was segmented by using a temporal sliding window of 5 seconds. Its format is (number of samples, 1, temporal window size, number of sensors)

Contributions to this repository are welcome. Examples of things you can contribute:

The table below shows the mean accuracy achieved by the methods using the Leave-One-Subject-Out (LOSO) as validation protocol. The symbol 'x' denotes which was not possible to execute the method on the respective dataset.
