Codes and Computing

genheas = Generate High Entropy Alloys Structures

genheas is a neural evolution structures (NESs) generation methodology combining artificial neural networks (ANNs) and evolutionary algorithms (EAs) to generate High Entropy Alloys (HEAs). https://github.com/CLEANit/genheas.

Unsupervised Hyperspectral Stimulated Raman Microscopy Image Enhancement: De-Noising and Segmentation via One-Shot Deep Learning

Deep learning and high harmonic generation

We use CNN & autoencoders to demonstrate many potential applications of deep learning in the field of high harmonic generation with strong fields https://github.com/CLEANit/HHG

Watch and Learn: transferable and generalized learning with physical law

Using RNN and EDNN to push the boundaries of what can be learned from a single set of observations https://github.com/CLEANit/watch_and_learn

RUGAN = Regressive upscaling generative adversarial network

RUGAN is a form of generative machine learning that can learn to mimic measurements from experiments or computer simulation. In the same way that generative adversarial neural networks can learn to make synthetic images of cats, RUGAN can make synthetic observations that are numerically accurate. For some implementations see https://github.com/CLEANit/RUGAN. For details and an interesting use case, see our publication.

Extensive deep neural networks

EDNN are a form of neural network which can learn from small systems and be used at arbitrary scale. Here are some implimentations. For more info, see our publication.

Leucippus

Leucippus is a plugin for the popular ImageJ project which can extract positional and compositional information from nanoscale microscopy data using computer vision.

HASHKAT (Agent Based Simulation)

(hashkat.org) HASHKAT is a dynamical network simulation tool designed to model the growth of and information propagation within an online social network. It is an agent-based, kinetic Monte Carlo engine capable of simulating online networks such as Facebook, Twitter, LinkedIn, etc. HASHKAT incorporates all elements of online social networks including multiple user profiles (e.g. standard users, organizations, celebrities, and bots), user messaging, trending topics, and advertising. Agents within the network make decisions (e.g. follow, unfollow, broadcast, and rebroadcast) based on a variety of user defined factors including geography, political affiliation, musical interests, and humour. HASHKAT allows for simulation of a realistic online social network, enabling users to test hypotheses for growth mechanisms and scenarios for information propagation. As it solves the forward problem, HASHKAT can be used with Big Data analytics tools to test data collection protocols and ensure inverse model validity.

Analysis scritps & codes we write

KIB, DOS, GW, MD

All of the above are hosted on github.org. They are free for use provided you cite us (see the README file for each repo for a paper reference if there is one, otherwise a weblink here is sufficient). To use them, simply type "git clone git://github.com/itamblyn/XXX.git" into your terminal (assuming you're using Linux or OS X), where XXX is the name of the desired repo. In case you're wondering, from Wikipedia: "Git is a distributed revision control and source code management system with an emphasis on speed".
