• Engaged in Click Through Rate prediction in personalized search ranking. Mainly used Python in Linux environment for feature engineering and model training.
• Used Hadoop framework to extract features from row click log dataset, conduct feature combination to explore new features and discretization of continuous features to improve the robustness of the model.
• Implemented the calculation of AUC through distributed computing to evaluate the features. Selected new features having top 10 highest AUC scores among 60 features.
• Conducted feature selection, noisy data cleaning and parameter tuning, reducing the loss of an on-line learning logistic regression model that uses FTRL as the optimizer by 10%.
• Trained the Wide & Deep learning model using TensorFlow framework to compare with regression model.
