We present our approach of using Recurrent Neural Networks (RNNs) for detecting transportation modes in the BigMM2016 Challenge. That is an end-to-end system working efficiently with the provided data. Even though we only used data collected from accelerometer sensor, which leads to low power consumption, our model still achieves a remarkable accuracy.

This work studies the transportation mode using big data from smartphone sensors. We use various machine learning algorithms to classify a smartphone user’s transportation mode and strike a balance between the accuracy, executive time, system delay, and model size. Finally, we choose a typical decision tree approach to do this project.
