# Load data
df = pd.read_csv('house_prices.csv')
X = df.drop(columns=['price'])
y = df['price']

# Data preprocessing
scaler = StandardScaler()
X_scaled = scaler.fit_transform(X)

# Split dataset
X_train, X_test, y_train, y_test = train_test_split(X_scaled, y, test_size=0.2, random_state=42)

# Train Lasso model

X = df.drop(columns=['target'])
y = df['target']

# Handle imbalanced data
smote = SMOTE(sampling_strategy='auto', random_state=42)
X_resampled, y_resampled = smote.fit_resample(X, y)

# Split into training and test sets
X_train, X_test, y_train, y_test = train_test_split(X_resampled, y_resampled, test_size=0.2, random_state=42)

print("Original dataset shape:", df['target'].value_counts())
print("Resampled dataset shape:", pd.Series(y_resampled).value_counts())

Gemini automatically:

  • Detects dataset imbalance.

  • Uses SMOTE to generate synthetic data and balance class distribution.

  • Resplits the dataset.

Best Practices

1. Clearly Define Analysis Goals

  • Provide specific objectives, such as "Analyze feature importance using Random Forest", instead of vague requests like "Train a model".
