Contributed to the OpenHUTB/nn repository by delivering three major features focused on deep learning and autonomous driving research. Modernized the MNIST CNN model using TensorFlow 2 Keras with pre-activation residual blocks and advanced data augmentation, improving recognition accuracy and robustness. Enhanced the CARLA autonomous driving platform by integrating PPO2-based and RL-Frenet trajectory planning, along with comprehensive verification and visualization tools for stability analysis. Reintroduced and optimized Restricted Boltzmann Machine training with improved performance and visualization. The work involved extensive Python programming, large-scale codebase refactoring, and cross-team collaboration, resulting in a more scalable and reproducible AI research platform.

Month: 2026-04 — Delivered substantial feature upgrades and stability improvements across the OpenHUTB/nn repo, enabling faster experimentation and more robust AI research workflows. Key features delivered include upgrading MNIST CNN to TensorFlow 2 Keras API with pre-activation residual blocks and enhanced data augmentation, boosting recognition accuracy and robustness; and expanding the CARLA autonomous driving research platform with PPO2-based trajectory planning, RL-Frenet trajectory planning suite, and comprehensive verification/visualization (Lyapunov stability, Frenet support, and multi-algorithm RL suite). Additionally, RBM training was reintroduced with performance-oriented optimizations and richer visualization. Major bugs fixed and stability enhancements include extensive refactoring and cleanup: CARLA module was streamlined from 233+ files to ~70 core Python files (with later consolidation to ~56 core files), main.py simplified into a single entry point, removed unused algorithms and obsolete support files, and imports/environment configuration cleaned up for reliability. Overall impact: improved model accuracy and robustness, faster experimentation cycles, and a scalable, reproducible research platform that aligns with business goals for AI perception and autonomous driving research. Technologies/skills demonstrated: TensorFlow 2 Keras, Python, data augmentation, PPO2, RL-Frenet, Lyapunov stability analysis, cubic_spline_planner, frenet_optimal_trajectory, CARLA environment tooling, RBM optimization, and large-scale codebase refactoring with cross-team collaboration.
