Classification of User Movement Data

Abstract

In this paper, a comprehensive analysis of various classification techniques is used on user movement data. The dataset used here utilizes a Nexus One Android smartphone, equipped with accelerometer sensor devices. The data was transformed and applied to two deep learning techniques: Convolutional Neural Network (CNN) and Long Short Term Memory-Recurrent Neural Network (LSTM-RNN). The results obtained via CNN and LSTM-RNN are compared with the traditional classifiers such as k-Nearest Neighbors (k-NN) and Feed Forward Neural Network (FFNN). The results show that the deep learning approaches were outperformed by the traditional classifiers on the applied dataset. While deep learning techniques reached a maximum accuracy of 84% utilizing LSTM, k-NN obtained an accuracy of 99.6%.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
