---

🔧 Preprocessing

• StandardScaler
• MinMaxScaler

---

🧪 Model Selection

• Train-Test Split

  • Supports stratify for balanced sampling

---

⚙️ Optimization Details

All models in rslearn are implemented using Gradient Descent.

⚠️ Important:

• Feature scaling is highly recommended for stable and faster convergence.

• Use:

  • StandardScaler (recommended)
  • or MinMaxScaler

• or just use scale=True parameter while fit()

---

🤖 Auto Standard Scaling (Linear, Logistic, Ridge, Lasso, ElasticNet)

models include Inbuilt StandardScaler Feature in fit() Method:

scale=True  # default

• Automatically applies feature scaling internally
• Helps prevent numerical instability
