Тема доповіді: Linear, Machine Learning and Probabilistic Approaches for Predictive Analytics

Тези доповіді:

  • We will consider the use of machine learning, linear and Bayesian models in the predictive analytics areas especially for time series modeling.
  • For machine learning approach, we will describe XGBoost tree based classifier to obtain high scored classification.
  • Using the generalized linear model for logistic regression makes it possible to analyze the influence of the factors under study.
  • The Bayesian approach for logistic regression gives the statistical distribution for the parameters of the model. It can be useful in the probabilistic analysis, e.g. risk assessment.
  • Results of different model combinations will be shown. We also will describe winner solution of our team on Kaggle competition “Grupo Bimbo Inventory Demand”.
