TATHAGATA GHOSH

Total 10 years of technical experience in Data Science / Analytics in Statistical Modeling, Machine Learning and Deep Learning in Structured and Unstructured data. Implemented various Machine Learning algorithms like Decision Tree, KNN, Random Forest, GBM, Gradient descent, stochastic gradient descent, XG Boost, ANN, CNN, Recommendation Engine and so on, using model selection methods like k-Fold cross validation and Hyper-parameter Tuning to find the best model. Implemented different Statistical Modelling techniques Linear/Logistic Regression, Clustering and Forecasting on different Business problem. Worked on for Text Mining and NLP Projects and used techniques like N-Gram analysis, Word-cloud, Text clustering, Decision Tree on textual data, Topic modelling, Document Search engine, Knowledge Graph and so on. I used different tools and programming languages like Python, R, SAS, Tensorfow, Keras, Py Spark, and Cloud to build Statistical Models, Machine Learning and Deep Learning Models.
