Select Software Packages

• npdr: Select features with nearest-neighbor concepts (2019)      
  a nearest-neighbor feature selection algorithm that fits a generalized linear model for projected distances of a given attribute over all pairs of instances in a neighborhood. In the NPDR model, the predictor is the attribute distance between neighbors projected onto the attribute dimension, and the outcome is the projected phenotype distance (for quantitative traits) or hit/miss (for case/control) between all pairs of nearest neighbor instances.
• pmlb: Penn Machine Learning Benchmarks (PMLB) (2020)      
  a repository contains the code and data for a large, curated set of benchmark datasets for evaluating and comparing supervised machine learning algorithms. These data sets cover a broad range of applications including binary/multi-class classification problems and regression problems.
• pmlbr: an R interface to PMLB (2020)      
  an R interface to the Penn Machine Learning Benchmarks data repository, a large collection of curated benchmark datasets for evaluating and comparing supervised machine learning algorithms.
• privateEC: Differential privacy for machine learning (2017)      
  a stochastic privacy-preserving machine learning algorithm that uses ReliefF for feature selection and random forest for privacy preserving classification.
• regens: REGENS (REcombinatory Genome ENumeration of Subpopulations) (2020)    
  An open source Python package 📦 that simulates whole genomes from real genomic segments. REGENS recombines these segments in a way that simulates completely new individuals while simultaneously preserving the input genomes’ linkage disequilibrium (LD) pattern with extremely high fedility. REGENS can also simulate mono-allelic and epistatic single nucleotide variant (SNV) effects on a continuous or binary phenotype without perturbing the simulated LD pattern.
• stir: ReliefF on steroid (2018)      
  Precursor of npdr
• tdapseudotime: Implements the temporal phenotyping via topological data analysis. (2020)    
• treeheatr: Heatmap-integrated decision tree visualizations (2020)      
  a more interpretable decision tree visualization by integrating a heatmap at its terminal nodes.

Courses and Workshops

• On visualization: Take a sad chart and make it better, R Ladies Philly, Dec 8, 2020      
  Every good chart started out as a bad one. In this workshop, we discuss 1) basic visualization principles, and 2) resources, tools, tips, and tricks that help improve our charts and refine our data stories. Some familiarity with R and ggplot will be useful but not required - novice R users are encouraged to attend.
• Fundamentals of AI guest lecturer, University of Pennsylvania, Mar 30, 2020      
  I give two 80-minute guest lectures on Information Theory and Stochastic Processes and their roles in artificial intelligence and biomedical applications.
• Machine learning workshop, R Ladies Philly, Dec 2, 2019      
  A brief introduction to machine learning and hands-on exercise of building models to predict the alcohol concentration of beers from a beer review dataset.
• Introduction to R seminar, University of Tulsa, Aug 25, 2017  
  An immersive, “bootcamp” styled seminar designed to rapidly build student proficiency in R programming. The seminar is conducted over a long weekend or similarly condensed timeframe in a computer laboratory setting.
• Precalculus instructor, University of Tulsa, Jan 11, 2016  
  I prepare 30+ students for the study of calculus.
• Calculus I & II teaching assistant, University of Tulsa, Jan 13, 2014  
  I lead Calculus I & II problem-solving sections and design and grade quizzes. I had 200+ students over the course of four semesters.
• Natural science tutors, University of Tulsa, Feb 7, 2011  
  I tutor students (including many student athletes) in math, physics and chemistry. I also worked in Math Lab - a free, walk-in tutor service for students at all levels.
