Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| AI can completely replace human analysis in time series forecasting. | While AI can assist in analyzing large amounts of data, it cannot replace the expertise and intuition of a human analyst. Human oversight is still necessary to ensure accurate and meaningful results. |
| GPT models are infallible and always produce accurate predictions. | GPT models are not perfect and can make mistakes or produce inaccurate predictions if they are not properly trained or if there is insufficient data available for analysis. It is important to regularly monitor model performance and adjust as needed to improve accuracy over time. |
| Time series analysis with AI will always provide clear-cut answers without any uncertainty or ambiguity. | Even with advanced AI techniques, there will always be some level of uncertainty or ambiguity in time series forecasting due to the inherent unpredictability of certain events or variables that may impact the outcome being predicted. It is important to acknowledge this uncertainty and use probabilistic methods when appropriate to manage risk effectively. |
| The more complex the model, the better its predictive power will be. | While complexity can sometimes lead to improved predictive power, it also increases the risk of overfitting – where a model becomes too closely tailored to specific training data at the expense of generalizability on new data sets – which ultimately reduces overall accuracy on out-of-sample datasets . A balance must be struck between complexity and simplicity based on what works best for each individual case study scenario. |
