Richard Creamer's Personal Website
interested in things that are interesting :-)
Me at my fav place
I really want to do technology projects with the potential to significantly help children and the world. I have worn software engineer/architect, entrepreneur, product management, and principal investigator hats for over 20 years in multiple, diverse fields, including many key startup roles. I really enjoy entering and innovating in new domains. Oh, and I much prefer to solve hard, real-world problems vs. puzzles ;-) I currently live in Northern California.

I rarely update this website anymore, but below are some older, historical updates...
- Mean Absolute Deviation in Python/Numpy - my StackOverflow answer
- This looks to be a good introduction to Deep Learning (URL)
- By invitation and for the 2nd time, I will again be a Community TA for the Stanford online Machine Learning course beginning Sept. 22, 2014 (Coursera).
- Kaggle.com Higgs Boson Challenge
- The purpose of this challenge was to identify a particular Higgs Boson decay event from background noise data.
- Below is a histogram of the predicted Real output numbers from an early Random Forest classifier. The best threshold on these Real outputs was found by applying the quantile() R function on the Train set labels.
- A few more details are here.
- Project Euler Solutions (coding examples):
- I just added a new page w/solutions to a few selected Project Euler problems. PLEASE do not use this code on ProjectEuler.net !
- Weight Lifting Exercises Dataset (Summary Page)
- I recently built a Random Forest classifier in R which classifies a human's exercise activity from 52 accelerometer and tilt/gryo sensor measurements. The training set had about 19,000 labeled samples.
- CodeEval Challenge: A quick C hack got me a 99.841% ranking on a CodeEval.com programming challenge:-) PLEASE do not use my code on CodeEval.com !
- Recent online ML/Data Science courses:
- Completed 3 online courses from the Johns Hopkins Data Science specialization series on Data Science:
- Certificates of completion and course topic summaries can be viewed here
- I just learned about and joined CodeEval.com, looking forward to finding time to solve some of the interesting challenges on this site!
- I just progressed to Level 2 on ProjectEuler.net (top 7.26%) by completing 50+ problems. Update: I added a new page w/ selected solutions/code. Screenshot showing advancement to Level 2:
