Classification of Activities and Falls within a Multimodal Dataset
2021 IEEE International Conference on Machine Learning and Applied Network Technologies (ICMLANT)(2021)
Abstract
Accurately predicting fall detection from wearable sensor data has many implications. Detecting falls and other activities from wearable data provide a method by which it assists those who need it. Multiple methods were employed to predict activities from wearable data. One method was using a Recurrent Neural Network(RNN) known as a Long Short Term Memory network (LSTM). In addition, a traditional machine learning approach was explored with the use of a Random Forest Classifler(RFC). This work was adapted from a few previous works, as the dataset being used was that of the Challenge Up competition. Despite utilizing previous methods and works, the highest accuracy attained was 72% which lends itself to the potential difficulty of predicting rare events from time-series data.
