Hi, Ritesh here.
I’m a machine learning engineer focused on building and understanding practical deep learning systems. I previously worked at Zomato and Samsung R&D Institute India.
I use this site to document what I learn while building machine learning projects.
From my notes
Fine-tuning a small model for tool calling
Fine-tuning Qwen2.5-0.5B on xLAM, the bugs I ran into, and how I evaluated the results.
Diffusion Models
Working through DDPM and DDIM, from the equations to a PyTorch implementation.
Position Encoding
Looking at sinusoidal positional encoding through code and plots, including what changes with the frequency base.
