Training a Neural Network for Word Separation
There are some 290k posts from social media site Hacker News in 2016. Training a deep learning model with a special loss function, the top 500 words used in these posts are projected into 2d space and then grouped using KMeans.

Plant Pairs on the Tufts Campus
![alexander wei website for applied mathematics and plant analysis](https://www.alexwei.net/wp-content/uploads/2022/08/dandChick_enhanced_210160_g.png)
In Spring of 2019 my Environmental Fieldwork class surveilled the herbaceous plants growing on and around the Tufts campus, recording their identities and locations into a GIS database. For a final project I created a simple Cartesian quadrature algorithm in Python to identify the distinct plant pairs most likely to share the same soil.
