Dr. Saffet Gokcen Sen

Working on causal learning, full-stack development, object oriented programming using Smalltalk and Java.; lecturing on causal learning, deep learning, electromagnetics. Have a blog about causal learning, machine learning and deep learning on https://saffetgokcensen.github.io/ Projects: 1) Verified the compliance between a DAG and the data produced by a software by AVL using d-separation-implications of the DAG proposed by mechanical engineers. 2) Proposed a DAG for an image, related articles on my blog.

Collection of health related data (NHANES, NHIS, etc.); building ML models from the collected data; feature engineering; using Keras, Tensorflow and Scikit-learn for ML models; utilization of Apache Spark in Scala language for data preprocessing and ML models (MLlib); building Google Dialogflow agents using either the console or Dialogflow Python API; writing fulfillment code for agents in Javascript; building postgresql databases for SNOMED and RxNorm; developing queries for SNOMED and RxNorm

Logistic regression, random forest with scikit-learn in Python for prediction and classification tasks. Random forest tree interpretation to get feature time-variaton. Scikit-learn's recall_precision_curve utility to fine-tune the binary classification threshold for high precision and recall. Keras in Python to build dense neural networks and LSTM networks for prediction and classification tasks. Used pandas for dataframe tasks in Python. Built many R scripts for ETL using dplyr, reshape, ggplot in RStudio.
