What Makes It Different

Three Pillars of Deep Learning

Math-First

Linear algebra, probability, and optimization form the bedrock. You understand why, not just how.

Code-Backed

Every concept is implemented from scratch. No hiding behind libraries until you understand the internals.

No Black-Box

We open every layer. Transformers, attention, backprop — you build them, you own them.
