Today I successfully completed the experiment of integrating holiday factors into the TCN model and conducting sales forecasting. The model runs normally in terms of structure and training, and external variables such as holidays are also successfully incorporated into the modeling process. However, when actually evaluating the forecast results, it was found that even after adding holiday variables, the performance of the model still could not adapt well to the sales characteristics of Ecoshop, the forecast error was still high, the trend fluctuated greatly, and it did not meet the conditions for actual deployment.

Therefore, after analysis and consideration, it was decided to temporarily end the research and experimental stage of the TCN model and start to explore the next cutting-edge time series forecasting model - N-BEATS (Neural Basis Expansion Analysis for Time Series).
