ag_implement

messy/quick wrapper implementations of some ML models, just for personal use

ag_inversion

Inverse problem solving tools, in progress

datasci_ipynbs

Miscellaneous data science / machine learning Jupyter notebooks

db_labeling_webapp

A simple gradio-based web-app that connects to a database, displays images, and allows to enter json tags.

docker_mlflow_db

A ready-to-run Docker container setup to quickly provide MLflow as a service, with PostgreSQL, AWS S3, and NGINX

dracula-tmux

My own tweaks on the awesome and popular 🧛🏻‍♂️ dark theme for tmux

fowl_fairy_code

DBSCAN image-clustering based automated reading and decryption of fairy cipher glyphs from 2nd Artemis Fowl book

C programs and shell script to read/filter data and calculate soundspeed profiles from NOAA's World Ocean Database 1998 (the version I used for many of my analyses; newer data is available at OCL website, with some filters, but these programs offer more in-depth filtering.)

gpt_client

gpt_client: a Python-based OpenAI GPT client that can be run as a terminal/readline based CLI or as a browser-based web-app

gravdragdemo

A comparison/demonstration of five predictive filters and smoothers (KF, KS, LKF, EKF, EKF2) based on an expansion of two examples in Gelb's "Applied Optimal Estimation", comparing and contrasting them in both linear and nonlinear cases in the measurements as well as in the dynamics. See my linked webpage discussing the problem.

gym_baghchal

Reinforcement learning applied to Bagh Chal board game, via OpenAI's Gym toolkit

icp_boxfit

fit a 3d box to a point cloud

inn_flow_tfp

A flow-based invertible neural network implemented with Tensorflow Probability

invgn

Calculate Tikhonov-regularized, Gauss-Newton nonlinear iterated inversion to solve the damped nonlinear least squares problem (Matlab code).

minisim

MiniSim was a Java2-based test demonstration for a networked Navy simulation client. The simulation networking component itself can't be shared with the public, but the client is separable from the simulator so this fun GUI part can be shared. For quick kicks, see screenshot.png and download/run MiniSimDemo.jar (via "java -jar MiniSimDemo.jar").

multiregresslines

MultiRegressLines runs multiple-line (up to three) segment regression on a dataset of X,Y data. This Java version of my code has some remaining math issues - till those are fixed please use the Matlab version for actual analysis (MultiRegressLines.matlab). For both, my linked webpage explains this topic of "multi-phase linear regression".

multiregresslines.matlab

The Matlab scripts in MultiRegressLines.matlab run a two-line-segment regression on a dataset of X,Y data, and analyze the uncertainties in that regression via Monte Carlo (since it's a nonlinear problem).

old_datatools

A minimal version of a JSci-like package from back before that was a viable option. So this is just a legacy library of mine that RayDemo, SpheRayDemo, and MultiRegressLines depend on.

ptolemyupdates

My updated versions of some old Ptolemy Plot (PTplot) class files, used in my dataTools, RayDemo, SpheRayDemo, and MultiRegressLines packages.

py_tf2_gpu_dock_mlflow

A ready-to-run Python/Tensorflow2/MLflow/Docker setup to train models on GPU and log performance and resulting model in MLflow.

quick_postgresql

Docker-compose setup for quick-prototyping a Postgresql database via Docker, serving SchemaSpy result via Nginx

rabbittrackeryolo

Train and test a yolov3 model that detects/tracks rabbits in our yard via grainy nighttime IR photos

raydemo

RayDemo is an interactive, graphical, geophysical raytrace applet, particularly useful for demonstration/tutorial purposes. Its focus is geophysical such as sound/earthquake waves propagting through the ocean or land, as opposed to light reflections between objects (a different popular use of raytracing for graphics needs).

spheraydemo

SpheRayDemo is a "spherical raytrace demonstration" of modeling raytraced ion acoustic waves propagating in the Sun. See my webpage on helioseismology for more. Bonus: this app's plots look like Spirograph art!

spice_clipper_traj

Fortran + Matlab/Octave to read/process NASA spacecraft trajectories from publicly available NAIF SPICE files for proposed Europa Clipper mission (thanks to NASA NAIF for assistance). While this same trajectory data is available independently online, this code provides a framework for processing trajectory data in spacecraft and lunar coordinates.
