    Before I start my internship @AMD AI next week, I spent some time on a project that I've been wanting to do for a while. I built a neural network framework from scratch in C++ to understand the fundamentals of automatic differentiation and computational graphs.

    For all the #drugdiscovery #compbio people, what's the inside scoop on "the valley of death"? Trying to understand the problem better from academic->commercialization and biotech-startup lens. Send case studies, links, and experts! CC: @pillar_vc @kulesatony @MichaelRetchin

    This was a pretty quick project, but it helped me build intuition on backpropagation, shape logic and graph execution. In the future, I want to experiment with N-D convs and pooling ops, operator fusion + threading beyond SIMD, and ML compilers (autoTVM, cuDNN, IR-level hacks)

    Basic matmul optimization: These really small models were performing pretty slow, so I ended up using xsimd for hardware-agnostic vectorized matrix multiplication that gave me an 8.6x speedup across all training scenarios. The inner loop uses SIMD batches to process multiple

    Going from scalars to tensors: To move from scalars to tensors, I had to implement an N-dimensional tensor class with shape and strides, matrix multiplication with proper gradient computation, NumPy-style broadcasting for element-wise operations, and gradient shape fitting for

    Effective system design: The first challenge was building computational graph nodes that could track their own gradients. Each Value object holds the data (scalars initially, tensors later), a gradient accumulator, an operation tag like "add" or "relu", and parent pointers for

    Testing the framework: To see if our code was actually suitable for learning and there weren’t any weird quirks in the math, I tested the framework on the XOR gate problem (non-linearly separable) and 4-feature binary classification tasks, comparing cross-entropy versus MSE loss

    Building the backward pass: This code automatically builds the graph and then computes gradients for all the nodes. Implementing the reverse-mode autodiff required three steps: > topologically sorting the computation graph (which was easy to do with our node design) > walking

    Anyone know any really smart HS students in ML X Bio? Working on a project and need some help with it (preferably anyone with exp. with GNNs and Representation Learning and ❤️ drug design) CC: @SeyoneC
