TI-Capsule: Capsule Network for Stock Exchange Prediction
This work addresses stock market prediction for traders and analysts by integrating multimodal data, but it appears incremental as it applies an existing method to a new combination of data types.
The study tackled stock exchange prediction by using a Capsule Network to analyze both finance texts and Candlestick images, achieving 91% accuracy on a collected dataset.
Today, the use of social networking data has attracted a lot of academic and commercial attention in predicting the stock market. In most studies in this area, the sentiment analysis of the content of user posts on social networks is used to predict market fluctuations. Predicting stock marketing is challenging because of the variables involved. In the short run, the market behaves like a voting machine, but in the long run, it acts like a weighing machine. The purpose of this study is to predict EUR/USD stock behavior using Capsule Network on finance texts and Candlestick images. One of the most important features of Capsule Network is the maintenance of features in a vector, which also takes into account the space between features. The proposed model, TI-Capsule (Text and Image information based Capsule Neural Network), is trained with both the text and image information simultaneously. Extensive experiments carried on the collected dataset have demonstrated the effectiveness of TI-Capsule in solving the stock exchange prediction problem with 91% accuracy.
