Extensive experience in Text Analytics, developing different Statistical Machine learning, Data Mining solutions to various business problems and generating data visualizations using R, R-shiny and Python.• Build various Recommendation engines, predictive models, real-time analytics and Price Optimization. • Data is mostly from a log entry for each ticket with respect to a problem where Filtered out unwanted characters from a text ticketing data.• Used NLP techniques, NLTK, Regular expressions, Keras and Tensorflow for preprocessing of the text.• Built and applied LSTM after cleaning the data.• Analyzed the performance with fine tuning techniques. Compared the LSTM Model with RNN, CNN, GRU, Word em-beddings. • Plotted the performance metrics from each model.• Performed Data Cleaning, features scaling, features engineering using pandas and NumPy packages in python. Ensure that the model has low False Positive Rate and Text classification and sentiment analysis for unstructured and semi-structured data.• Designed, developed and tested applications for text processing, such as name or entity matching, text categorization/routing, named-entity extraction, sentiment analysis.
