Auto Holt-Winters Seasonal (HWS)

• Auto Holt-Winters Seasonal (HWS) is an extension of the Holt-Winters (Triple Exponential Smoothing) method that automatically selects the best smoothing parameters (α,β,γ) alpha, beta, gamma for level, trend, and seasonality.
• Instead of manually tuning these parameters, Auto HWS uses optimization techniques to minimize forecasting error (e.g., Mean Squared Error).
