Today felt really good.
I went deeper into cost functions and finally built a clearer mental model of what they represent and why minimizing them actually improves a model. I also made small input-level changes in the linear regression model I’m building, which helped connect the math to actual code behavior.
On the DSA side, I revised the two-pointer technique and ended up solving a sliding window problem without even realizing it was two pointers at first. That moment when the solution naturally fits a pattern is super motivating — and yes, the two-pointer approach worked perfectly.
I also shipped a UI interaction update to my portfolio: added a second-page component where clicking the menu causes the main screen to slide and reveal navigation. Subtle, clean, and honestly… it looks really cool.
What I worked on today
ML: Built deeper intuition around cost functions, Updated a linear regression model with input variations
DSA: Revised two pointers and solved a sliding window problem
Portfolio: Added a menu slide interaction to my portfolio website
hmmmm....what did i do today?
What this reminded me
Progress isn’t always loud. Sometimes it’s realizing you already understand more than you thought.
