🧠 ML Implementation Details
- Logistic Regression chosen for binary classification
- Simple, interpretable, and effective for medical predictions
- Fast training and prediction times
# Input Features
features = [
'Age', # Continuous variable (1-120)
'Smokes', # Binary variable (0/1)
'AreaQ', # Ordinal variable (1-10)
'Alkhol' # Binary variable (0/1)
]
# Target Variable
target = 'Result' # Binary (0: Negative, 1: Positive)- Data Loading: CSV file with lung cancer examples
- Data Preprocessing: Remove non-essential columns
- Train-Test Split: 80/20 split with random_state=42
- Model Training: Logistic Regression with default parameters
- Model Serialization: Save using pickle for deployment
from sklearn.metrics import classification_report, confusion_matrix
# Generate predictions
y_pred = model.predict(X_test)
# Performance metrics
accuracy = model.score(X_test, y_test)
precision = precision_score(y_test, y_pred)
recall = recall_score(y_test, y_pred)
f1 = f1_score(y_test, y_pred)🔌 API Endpoints
