Predictive Data Modeling: How it Works

What is the goal of UCIPT's Twitter sentiment model? The goal of the Twitter sentiment model is to predict the sentiment (positive, neutral, or negative) of a given tweet accurately. However, it is only a part of the big picture that our group has in mind. By developing a model that can predict sentiments of tweets accurately, we intend to automate the entire process of labeling an incoming stream of tweets. Through such automation, we hope to predict meaningful things such as students' stress level and GPA by analyzing a vast amount of data available on Twitter. How do you use a neural network to improve the accuracy of your predictions?
