I am researcher in wide range of scientific fields. Implemented Machine Learning methods for oil pumping, stock trading, recommender systems, detection anomalies in business' KPIs, object tracking tasks. Frameworks: Matlab, Python (pandas, numpy, sklearn, keras, nltk, scipy, matplotlib). Methods: Deep Fully Connected Neural Networks, Convolutional Neural Networks, Ansamblis of Trees (Boosted Trees, Random Forest), SVM. Have huge experience in feature engineering. Understand how features may be extracted, how to avoid data leakage, how to estimate quality of ML algorithms. I am good at time series processing: Fourier analysis, Wavelets, Correlation functions, etc. PhD of Moscow Institute of Physics and Technology.
