In this paper we have made an attempt to model the historic prices of the TCS- Tata Consultancy Services and calculated its accuracy for different epochs and batch sizes, forbye the ramifications of data preprocessing. Further the tweets related to it are scrutinized for the model. Our paper makes an attempt in providing a panorama over different data manipulations and the fidelity procured, we have provided a comparative study herein.
