Fast architecture assessment without training:
from morphml.evaluation import HeuristicEvaluator
evaluator = HeuristicEvaluator()
score = evaluator(graph) # Instant evaluation
# Get detailed scores
scores = evaluator.get_all_scores(graph)
print(scores) # {'parameter': 0.85, 'depth': 0.92, ...}Save and resume long-running searches:
from morphml.utils import Checkpoint
# Save during optimization
Checkpoint.save(ga, 'checkpoint.json')
# Resume later
ga = Checkpoint.load('checkpoint.json', search_space)
best = ga.optimize(evaluator)Compare different search strategies:
from morphml.optimizers import GeneticAlgorithm, RandomSearch, HillClimbing
# Baseline
rs = RandomSearch(space, num_samples=100)
baseline_best = rs.optimize(evaluator)
# Main search
ga = GeneticAlgorithm(space, population_size=50, num_generations=100)
ga_best = ga.optimize(evaluator)
# Refinement
hc = HillClimbing(space, max_iterations=50)
hc.current = ga_best
