Learning Faster without Deeper Networks: A*-Inspired Batch Selection for Efficient CNN Training

arXiv cs.LG · 6d ago Cached

The paper proposes A*-Inspired Batch Selection (A*-BS), a lightweight strategy that treats mini-batch scheduling as a heuristic search to improve CNN training efficiency. On MedMNIST tasks, a simple CNN with A*-BS outperforms deeper ResNet-18/50 baselines in accuracy and training speed.

@dunik_7: the difference between a $4 agent run and a $0.40 one comes down to a single idea: the heuristic. lecture 6 of Stanford…

X AI KOLs Timeline · 2026-05-23 Cached

This Twitter thread highlights Stanford CS221 lecture 6 on heuristics, explaining how A* search improves agent efficiency by using heuristics to guide decision-making. Key takeaways include building heuristics by relaxing problems, the danger of bad heuristics, and the optimality of A* with the right estimate.

Petri Net Induced Heuristic Search for Resource Constrained Scheduling

arXiv cs.AI · 2026-05-18 Cached

This paper models the Resource-Constrained Project Scheduling Problem as optimal search over a Petri net reachability graph and solves it with A* guided by a consistent heuristic combining critical path and resource lower bounds, outperforming MIP baselines on PSPLIB benchmarks.
