Open-source disaster risk intelligence platform for US municipalities — powered by FEMA, USGS & NOAA public data
Off-grid IR mesh network that retrofits solar street lamps for disaster communication — gradient routing, no power grid, no mobile network needed.
A deep reinforcement learning system for optimizing bridge maintenance decisions across municipal infrastructure fleets, implementing cross-subsidy budget sharing and cooperative multi-agent learning.
Quantile Regression DQN implementation for bridge fleet maintenance optimization using Markov Decision Process. Migrated from C51 distributional RL (v0.8) with 200 quantiles and Huber loss. Features: Dueling architecture, Noisy Networks, PER, N-step learning. All 6 maintenance actions show positive returns with 68-78% VaR improvement.
A comprehensive reinforcement learning system for pump equipment condition-based maintenance using DQN (Deep Q-Network) with quantile regression and aging factor integration.
W.O.M.B.A.T. Terminal Offline Edition
There are already applications for managing and distributing waste in Indonesia. With those apps as a reference, we tried to design a similar application by emphasizing the unique aspects of sorting and channeling types of residential waste. We want to make an application that can detect six types of residential waste by scanning the camera on a…
Deep Q-Network implementation for optimal bridge maintenance planning using Markov Decision Process formulation with vectorized parallel training. Based on Phase 3 (Vectorized DQN) from dql-maintenance-faster project.
Deep Q-Network (DQN) implementation for optimal maintenance planning of 100-bridge fleet infrastructure using advanced reinforcement learning techniques and vectorized parallel training.
Markov Decision Process DQN with Noisy Networks for Exploration (ICLR 2018) - 21.1% performance improvement over ε-greedy.
Interactive flood-risk simulation for urban Chennai — terrain-based drainage analysis with a real-time "what-if" rainfall scenario engine. DEM pipeline → simplified hydraulic proxy (HEC-RAS upgrade planned) → live web dashboard.
C51 Distributional DQN (v0.8) for bridge fleet maintenance optimization. Implements categorical return distributions (Bellemare et al., PMLR 2017) with 300x speedup via vectorized projection. Combines Noisy Networks, Dueling DQN, Double DQN, PER, and n-step learning. Validated on 200-bridge fleet: +3,173 reward in 83 min (25k episodes).
