Folium is a useful library for visualization of maps. Here we see a visualization of the distribution of taxi pickups for a certain day at 5pm in Manhattan. I’ve been using Folium for my research w...

Stress strain data from our experiments are curves. For example, The upstream data are pickled files. They must be processed and uploaded to s3 for downstream consumption. Our Airflow DAGs will...

This is an example of how one can solve OT using linear programming for small cases. The cost matrix is sampled from Uniform(0,1). Naturally, this won’t work well with large $n$, as it’s $O(n^3)$ –...

Before any analysis can be done with MRI scans, image registration must be done. Patients can be in many positions when they get their scans. The heads may be slightly tilted or rotated. Image regi...

An API gateway serves as an intermediary between the client and the backend services by providing a unified entry point for all API calls. It accepts incoming requests from clients, routes them to ...

This is an attempt to do image segmentation using machine learning and FreeSurfer. The brain tumor segmentation (or BraTS) dataset was used. The model is based on a volume-to-volume Generative Adve...

When developing, we seldom see serious memory thrashing issues. I was fortunate enough to see an issue with an application that was built many years ago. (Note: I was not the developer of the app. ...

Aspect-oriented programming (AOP) is a programming paradigm that separates (or decouples) out cross-cutting concerns in our objects. It’s common to see logging messages scattered in various places....

If you see #include <bits/stdc++.h>, this is not a standard header. You see this often in competitive programming posts. You may have trouble compiling your code as a result. The solution is...

The original formulation for Cronbach’s alpha takes this form: [\alpha = \frac{N}{N-1}\left(1 - \frac{\sum_{i=1}^{N} \sigma_{y_{i}}^{2}}{\sigma_{T}^{2}}\right)] , where $N$ represents the number ...
