Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Model training is a purely objective process. | While model training involves mathematical algorithms, it is still subject to human biases and assumptions in the data selection and preprocessing stages. It’s important to acknowledge these potential biases and take steps to mitigate them. |
| More data always leads to better models. | While having more data can improve model accuracy, there are diminishing returns as the amount of data increases beyond a certain point. Additionally, not all data may be relevant or useful for the specific problem being addressed by the model. Quality over quantity should be prioritized when selecting training data. |
| Overfitting is always bad for models. | Overfitting occurs when a model becomes too complex and fits noise in the training dataset rather than generalizing well to new datasets (i.e., high variance). However, some level of overfitting may be necessary for certain applications where precision is critical (e.g., medical diagnosis). The key is finding an appropriate balance between bias and variance that minimizes overall error on new datasets while achieving desired levels of precision or recall on specific tasks within those datasets. |
| Models trained with biased or incomplete data will produce unbiased results if tested on diverse populations. | This assumption ignores how machine learning models learn from patterns in their input features during training which can lead them to perpetuate existing biases even when applied outside their original context (i.e., transfer learning). To address this issue, it’s important to evaluate models across different subgroups of interest during testing and consider using techniques like adversarial debiasing or fairness constraints during training. |
| Once a model has been trained, its job is done. | Machine learning models require ongoing monitoring after deployment since they can become outdated as new trends emerge in the underlying distribution of inputs they were designed for (i.e., concept drift). Regular retraining with updated datasets may be necessary to maintain model performance over time. Additionally, models should be evaluated for potential unintended consequences or ethical implications that may arise from their use in real-world applications. |
