This project develops an optimal scheduling algorithm to minimize the total cost for charging and discharging of electric vehicles.
Stock-Market-Prediction-using-ELMo-Sentiment-Classification-or-RNNs
This project aims to predict the stock market trend for the next day based on the sentiment classification on the daily news or the analysis on the historical time series data.
Twitter-Stream-Mining-using-Python-NLTK-and-MongoDB
This project aims to receive the data from Twitter stream, store the data into MongoDB database, and then mine the word frequency and tweet frequency.
