Data Science - Time Series Forecasting with Facebook Prophet in Python - The Naive Forecast and the Importance of Baseli

The video tutorial introduces the naive forecast method, emphasizing its role as a baseline in machine learning. It explains the importance of baselines for meaningful model evaluation and highlights common mistakes, such as overfitting and ignoring out-of-sample data. The naive forecast is described as a simple method for time series prediction, often used as a benchmark. The tutorial also critiques the misuse of advanced models like LSTMs in stock prediction without comparing them to naive forecasts. Finally, it discusses the random walk hypothesis, which suggests that stock prices follow a random pattern, making naive forecasts theoretically optimal.
