Pruning and evaluation
Pruning in the ToT approach is an effective mechanism for managing cognitive complexity by systematically reducing the search space. The process involves selectively eliminating less promising thought branches through intelligent evaluation techniques, using heuristic scoring methods that assess each potential path’s likelihood of leading to an optimal solution. By dynamically filtering out low-potential thoughts and focusing computational resources on the most promising reasoning trajectories, ToT pruning enables more efficient and targeted problem solving, balancing exploration breadth with reasoning depth.
- Let’s implement a basic pruning strategy by defining a simple pruning function:
def pruning_tot( model, tokenizer, problem, max_depth=3, max_branches=3, prune_threshold=0.5 ): def explore_and_prune(current_thought, depth): ...
