🚀 Quick Start

Installation

# Core package
pip install eclipsera

# With performance optimizations (recommended)
pip install eclipsera[perf]

# For plotting and visualization
pip install eclipsera[plot]

# Everything
pip install eclipsera[all]

First Steps

import numpy as np
from eclipsera.ml import RandomForestClassifier
from eclipsera.model_selection import train_test_split

# Generate sample data
X = np.random.randn(150, 4)
y = np.random.randint(0, 3, 150)
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

# Train and evaluate
model = RandomForestClassifier(n_estimators=100, random_state=42)
model.fit(X_train, y_train)
score = model.score(X_test, y_test)

print(f"✅ Accuracy: {score:.3f}")

🌟 Advanced Features

🤖 AutoML - Automatic Algorithm Selection

from eclipsera.automl import AutoClassifier

# Let Eclipsera find the best algorithm
auto_clf = AutoClassifier(cv=5, verbose=1)
auto_clf.fit(X_train, y_train)

print(f"🏆 Best: {auto_clf.best_algorithm_} (score: {auto_clf.best_score_:.4f})")

🔍 Model Explainability

from eclipsera.explainability import permutation_importance

# Understand what drives your model
result = permutation_importance(model, X_test, y_test, n_repeats=10)
for i, importance in enumerate(result['importances_mean']):
    print(f"📊 Feature {i}: {importance:.4f}")

🔗 Complete ML Pipeline

from eclipsera.pipeline import Pipeline
from eclipsera.preprocessing import StandardScaler
from eclipsera.feature_selection import SelectKBest
from eclipsera.decomposition import PCA
from eclipsera.ml import LogisticRegression

# Build sophisticated workflows
pipe = Pipeline([
    ('scaler', StandardScaler()),
    ('selector', SelectKBest(k=20)),
    ('pca', PCA(n_components=10)),
    ('classifier', LogisticRegression())
])

pipe.fit(X_train, y_train)
print(f"🎯 Pipeline Score: {pipe.score(X_test, y_test):.4f}")
