Intense flare duration origin tracing

Brief introduction

This project traces back the key factor magnetic area that determines the duration of an intense flare.
Model: Resnet18 & ViT
Training set: all JSOC sharp_cea_720s magnetogram FITs sliced 24 hours up to the beginning of a M & X class flare, year 2010 - 2022
Model discovers that single polarity area contributes more to flare duration rather than polarity inversion line, which is counter intuitive

Image generation based on multiple colored triangles

Introdcution

This project is an implementation of a mutated evolution algorithm
Target: 100 triangle with different color and location stack together to simulate target image
Next generation & mutation: relocate 3 apexes of triangle & randomized a color
Loss: summation of pixel value difference between generated image and target after each geneartion

RNA sequence auto label with GNN

Project Introduction

There are RNA sequences linked as a graph, but some of them are not properly labeled.
We utilize a customized Graph Neural Network to learn the relation within graph and extrapolate these label.
Model: a customized GNN, structure shown above
Dataset: as shown above
