Human Activity Recogonition Using Smartphones - KNeighbors Classifier

In this project you will design a robust activity recogonition system based on the smartphones. As you know mobile devices have accelerometer as the sensor which collects the activities. These activities can be classified using K-nearest neighbour.

REQUIREMENT

  1. Pandas
  2. Numpy
  3. Matplotlib
  4. Scikit Learn

Data

We will be using a human-activity-recognition-with-smartphones from the Kaggle platform which has a very good collection of datasets.

The file we will be using is present in following directory : input/ It is under license CCO and it is by UCI machine learning repositories

Attribute Information:

For each record in the dataset it is provided:

  • Triaxial acceleration from the accelerometer (total acceleration) and the estimated body acceleration.
  • Triaxial Angular velocity from the gyroscope.
  • A 561-feature vector with time and frequency domain variables.
  • Its activity label.
  • An identifier of the subject who carried out the experiment.

License

STEPS :

  1. Importing Libraries
  2. Exploring the Dataset
  3. Exploratory Data Analysis
  4. Data Preprocessing
  5. Model Building
    • KNeighborsClassifier
  6. Evaluation
  7. Conclusion

Run

In a terminal or command window, navigate to the top-level project directory Activity_recognition_KNN/ (that contains this README) and run one of the following commands:

ipython notebook Activity recognition_KNN.ipynb or

jupyter notebook Activity recognition_KNN.ipynb

This will open the Jupyter Notebook software and project file in your browser.
