🎯 Quick Start

Define a Search Space

from morphml.core.dsl import create_cnn_space, SearchSpace, Layer

# Option 1: Use pre-built template
space = create_cnn_space(num_classes=10)

# Option 2: Define custom space
space = SearchSpace("my_cnn")
space.add_layers(
    Layer.input(shape=(3, 32, 32)),
    Layer.conv2d(filters=[32, 64, 128], kernel_size=[3, 5]),
    Layer.relu(),
    Layer.maxpool(pool_size=2),
    Layer.flatten(),  # Essential for CNN -> Dense transition
    Layer.dense(units=[128, 256, 512]),
    Layer.output(units=10)
)

Run Architecture Search

from morphml.optimizers import GeneticAlgorithm

# Configure optimizer
ga = GeneticAlgorithm(
    search_space=space,
    population_size=50,
    num_generations=100,
    mutation_rate=0.2,
    elitism=5
)

# Define evaluator
def evaluate(graph):
    # Your training/evaluation logic
    return accuracy

# Run search with progress tracking
def callback(gen, pop):
    stats = pop.get_statistics()
    print(f"Gen {gen}: Best={stats['best_fitness']:.4f}")

best = ga.optimize(evaluator=evaluate, callback=callback)
print(f"Best fitness: {best.fitness:.4f}")

Export Architecture

from morphml.utils import ArchitectureExporter

exporter = ArchitectureExporter()

# Generate PyTorch code
pytorch_code = exporter.to_pytorch(best.graph, 'MyModel')
with open('model.py', 'w') as f:
    f.write(pytorch_code)

# Generate Keras code
keras_code = exporter.to_keras(best.graph)
with open('model_keras.py', 'w') as f:
    f.write(keras_code)

✨ Enhanced Features (P1-P3)

Adaptive Operators

Automatically tune crossover and mutation rates based on population diversity:

from morphml.optimizers.adaptive_operators import AdaptiveOperatorScheduler

scheduler = AdaptiveOperatorScheduler(
    initial_crossover=0.8,
    initial_mutation=0.2
)

# During optimization
crossover_rate, mutation_rate = scheduler.get_rates(
    population, best_fitness, generation
)

Crossover Visualization

Visualize how parent architectures combine:

from morphml.visualization.crossover_viz import quick_crossover_viz

quick_crossover_viz(parent1, parent2, "crossover.png")

Enhanced Constraint Messages

Get detailed violation information:

from morphml.constraints import ConstraintHandler, MaxParametersConstraint

handler = ConstraintHandler()
handler.add_constraint(MaxParametersConstraint(max_params=1000000))

if not handler.check(graph):
    print(handler.format_violations(graph))
    # Output:
    # Found 1 constraint violation(s):
    # 1. max_parameters
    #    Message: Architecture has 1,250,000 parameters, exceeding limit by 250,000
    #    Actual: 1,250,000
    #    Expected: <= 1,000,000
    #    Penalty: 0.2500

Custom Layer Handlers

Extend export system for custom operations:

exporter = ArchitectureExporter()

def attention_handler(node, shapes):
    return f"nn.MultiheadAttention(embed_dim={node.params['dim']}, num_heads={node.params['heads']})"

exporter.add_custom_layer_handler("attention", pytorch_handler=attention_handler)

🛠️ Utilities

Heuristic Evaluation

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, ...}

Checkpointing

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)

Multiple Optimizers

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
refined_best = hc.optimize(evaluator)
