### Leader Board
Average score across all four time series (30n120w, 30n140w, 40n160w, & 50n140w)

| Model | Description | Error |
|---|---|---|
| TBATS | Exponential smothing state space model with Box-Cox Transformation | ? |
| AR(6) | AutoRegressive order 6 models | MSE = 0.10 |
| ARMA | AutoRegressive Moving Average, order(6,2) | MSE = 0.13 |
| SARIMAX | Seasonal AutoRegressive Integrated Moving Average with eXogenous regressors, order(6,2,1)(6,2,1,4) | MSE = 0.13 |
| Persistence | "walk-forward" validation | MSE = 0.28 (1-day), 0.29 (3-day), 0.65 (9-day) |

| Long Short-Term Memory (LSTM) | Architecture | Error |
|---|---|---|
|LSTM_1var | Sequential 5 neuron LSTM, 1 neuron Dense output layer, tanh activation, SGD optimizer, fit with 20 epochs, 520 batch size, forecasting 5-day sequence based on the previous 20 days, features are only SST | |
