My Projects

Projects I have worked on recently.

Canonical-AMR top-3 across 3 days: 0.17, 0.00, 0.403

Antibiotic Resistance — Mutation Trajectory Prediction

Predicting the next resistance mutation given an ordered evolution history, over ALEdb plus CARD plus deep mutational scanning data. A LightGBM + autoregressive transformer + reranker stack lifts canonical-AMR top-3 from 0.17 to 0.403 across 14 drug classes.

Cross-cohort AUROC: 0.217 Day 2 versus 0.850 Day 3 on GSE122126

cfDNA Cancer Detection — A Cross-Cohort Recovery Story

Cell-free DNA methylation cancer detection over the Loyfer atlas. Cross-cohort AUROC on GSE122126 went from 0.217 (below random, model inverted) to 0.850 across four of five cancer types. The four mechanisms that closed the gap, and the literature check that showed they're not novel.

P3/time AUROC across splits: Day 1 baseline vs Day 3 leak-clean fusion

Clinical Trial Failure Prediction

Phase-3 trial outcome prediction over the AACT clinical trials database, with a leakage audit that proved the headline number is signal, not label encoding. Audited AUROC 0.8603. The audit methodology is the part worth carrying forward, not the model.

Halothane vs hexafluoroethane network-state response on the C. elegans Cook 2019 connectome — anesthetic pushes command-interneuron firing into quiescent regime, non-immobilizer does not, across four orders of magnitude in dose.

Anesthesia Pipeline — Network-State Validation

Connectome-constrained network-state validator for C. elegans anesthesia. Predicts immobilization EC50, mutant phenotypes, and Eger non-immobilizer specificity from literature-grounded multi-target perturbation profiles applied to a 300-neuron Brian2 brain.

ARC-AGI puzzle showing a blue input grid transforming into a green output grid, with a multi-step transformation strip — Rohit Ravi's ARC Prize 2025 entry

ARC Prize 2025

Ongoing attempt at the ARC-AGI benchmark — a pipeline-based approach to program synthesis, symmetry reasoning, and abstraction discovery.

Illustrated C. elegans worm with colored neural-network overlay — Rohit Ravi's connectomics + transcriptomics project

C. elegans Connectomics + Transcriptomics

Multi-modal analysis asking how much of local wiring in a small nervous system is determined by topology vs. gene expression.

Polymer chain mapped to a scatter plot of molecular features vs. predicted property — Rohit Ravi's NeurIPS Polymer Prediction Kaggle entry

NeurIPS Polymer Prediction

Kaggle competition for predicting polymer properties from SMILES-style representations — a multi-phase hybrid pipeline combining gradient-boosted and deep models.

Side-by-side illustration of ground-truth and predicted RNA 3D tertiary structures with a base-pair / hydrogen-bond legend — Rohit Ravi's Stanford RNA 3D Folding entry

Stanford RNA 3D Folding

Kaggle competition entry for predicting RNA 3D structure from sequence — a pipeline + evaluation stack using TM-align for structural scoring.

Illustration of a human painter and an AI robot painting the same scene — Rohit Ravi's AI vs. Human Art classifier project

AI vs. Human Art Classification

A deep-learning classifier that distinguishes AI-generated from human-made artwork, with interpretability via Grad-CAM, t-SNE, and PCA.

Pipeline diagram: Cellular Automata → Attention → Causal Graph → Symbolic Rules — architecture of Rohit Ravi's Hybrid Symbolic Discovery Engine

HSDE — Hybrid Symbolic Discovery Engine

Neural-symbolic reasoning prototypes: a recursive CA + attention + symbolic hybrid, and an Enhanced Symbolic Discovery Engine targeting AIME / SAT / GSM8K.

OnServe Tennis — Website

Website for OnServe Tennis, built in React. An earlier full-stack project from before I moved primarily into ML research.

Code-OCR

An OCR tool for interpreting source code images (.jpg, .png) and outputting machine-readable text — an early exploration of vision-to-code conversion.

GG Tennis Academy — Website

Website for GG Tennis Academy. An early web-development project from before I moved primarily into ML research.

Carbon Emissions Tracker — Florida Hacks with IBM

Hackathon project for Florida Hacks with IBM — a carbon emissions tracking app to help users quantify and reduce their footprint.
