I worked on short-term prediction of demand for ride-hailing services project. Exploiting traditional time series approaches for this problem is challenging due to strong surges and declines in pickups, as well as spatial concentrations of demand. This leads to pickup patterns that are unevenly distributed over time and space. We present UberNet, a deep learning approach that employs a multivariate framework that utilises a number of temporal and spatial features to explain the demand for ride-hailing services. Specifically, the proposed model includes two sub-networks that aim to encode the source series of various features and decode the predicting series, respectively.Another project that I worked on is Event Detection in social media. The proposed architecture is based on state-of-the-art language models, e.g., BERT, ALBERT, roBERTa using tools like Spark, HuggingFace and Keras.
