Comparison-of-Hybrid-Neural-Network-Methodologies-for-Sentiment-Emotion-Analysis

Twitter tweets play an important role in every organisation. This project is based on analysing the English tweets and categorizing the tweets based on the sentiment and emotions of the user. The literature survey conducted showed promising results of using hybrid methodologies for sentiment and emotion analysis. Four different hybrid methodologies have been used for analysing the tweets belonging to various categories. A combination of classification and regression approaches using different deep learning models such as Bidirectional LSTM, LSTM and Convolutional neural network (CNN) are implemented to perform sentiment and behaviour analysis of the tweets. A novel approach of combining Vader and NRC lexicon is used to generate the sentiment and emotion polarity and categories. The evaluation metrics such as accuracy, mean absolute error and mean square error are used to test the performance of the model. The business use cases for the models applied here can be to understand the opinion of customers towards their business to improve their service. Contradictory to the suggestions of Googleโ€™s S/W ratio method, LSTM models performed better than using CNN models for categorical as well as regression problems.

A-simulation-and-optimization-of-the-HS2-line-from-London-to-Birmingham

The main aim of this project is to create a simulation of a railway line and determine the optimal number of signalling blocks between LONDON and BIRMINGHAM and the number of trains every hour in this track line. This optimization takes into consideration the assumption of maximizing the throughput of passengers and minimizing the travel time of a passenger from the first station to the last. The assumption of two types of trains is given where a maximum of 420 or 630 passengers respectively in each type of train can travel.
