Back in April 2019, I gave a presentation at Strata AI [https://conferences.oreilly.com/artificial-intelligence/ai-ny-2019/public/schedule/detail/73209] on a prototype API to track model development metadata for reproducibility using a simple 3-layer 2D CNN for a basic image classification task. I was planning to submit this

Organizing files in train/test directories

Organizing files in train/test directories

For a prototype model I'm writing that involves a multi-class problem with facial images, I've found the need to use some basic Python code to organize my image files and partition them into train and test directories. I thought it might be helpful to post this

Exploring Different Data Preprocessing Methods for LSTMs

Exploring Different Data Preprocessing Methods for LSTMs

I tend to focus a lot on how the data is wired, snipped, and prepared for models. I think the preprocessing steps of data lay the foundations by which all models are built and provides me a highly valuable exercise to understand the nooks and crannies of my dataset, especially

Deploying an R Shiny App to AWS

Deploying an R Shiny App to AWS

For a recent company project, I helped deploy an R Shiny app developed by a teammate to AWS. There are multiple blogs online that provide great, detailed instructions on how to do this. After doing it several times now, I wanted to share the website that I thought provided the
