AI accuracy of stock trading models can be compromised by underfitting or overfitting. Here are 10 ways to assess and reduce the risk associated with an AI predictive model for stock trading.
1. Analyze model Performance on In-Sample Vs. Out of-Sample Data
Why is this? The high accuracy of the sample but poor performance outside of it indicates overfitting.
How: Check if the model performs consistently across both sample (training) as well as outside-of-sample (testing or validation) data. If performance significantly drops beyond the sample, it is possible that overfitting has occurred.
2. Verify that cross-validation is in place.
What is it? Crossvalidation is an approach to test and train a model using different subsets of data.
How: Verify that the model utilizes Kfold or a rolling cross-validation. This is particularly important when dealing with time-series data. This will give a better idea of the model’s real-world performance and will identify any signs of over- or underfitting.
3. Evaluation of Model Complexity in Relation to the Size of the Dataset
Highly complex models using small datasets are prone to memorizing patterns.
How? Compare how many parameters the model has in relation to the size of the data. Simpler models (e.g. linear or tree-based) are usually preferable for smaller datasets, whereas more complex models (e.g., deep neural networks) require more information to prevent overfitting.
4. Examine Regularization Techniques
Reason: Regularization e.g. Dropout (L1, L2, 3) reduces overfitting through penalizing models with complex structures.
How: Check that the model is utilizing regularization techniques that fit its structure. Regularization is a method to limit the model. This helps reduce the model’s sensitivity to noise, and improves its generalizability.
Review Methods for Feature Selection
What’s the reason: The model may learn more from noise than signals when it is not equipped with irrelevant or excessive features.
How to: Go through the procedure for selecting features and make sure that only the relevant choices are chosen. Techniques to reduce dimension, such as principal component analysis (PCA) can help simplify the model by removing unimportant features.
6. Think about simplifying models that are based on trees using techniques like pruning
Reason: Tree-based models such as decision trees, can be prone to overfitting when they get too far.
How: Confirm whether the model is simplified by using pruning techniques or other technique. Pruning is a way to eliminate branches that create more noise than patterns that are meaningful and reduces overfitting.
7. Model Response to Noise
Why? Because models that are overfit are sensitive to noise, and even minor fluctuations.
To determine if your model is robust Add small quantities (or random noise) to the data. Watch how the predictions of the model shift. The robust models can handle the small fluctuations in noise without causing significant changes to performance and overfit models could react unexpectedly.
8. Study the Model Generalization Error
Why: Generalization error reflects the accuracy of a model’s predictions based upon previously unobserved data.
How do you determine the differences between mistakes in training and the tests. A large difference suggests overfitting. But, both high testing and test results suggest underfitting. Try to find an equilibrium between low errors and close values.
9. Find out more about the model’s curve of learning
The reason: Learning curves demonstrate the relationship between performance of models and training set size, that could be a sign of either under- or over-fitting.
How do you plot the learning curve: (Training and validation error vs. the size of the training data). Overfitting leads to a low training error but a large validation error. Underfitting shows high errors for both. Ideal would be to see both errors reducing and converging with the more information collected.
10. Determine the stability of performance under various market conditions
The reason: Models that are susceptible to overfitting may only perform well in certain market conditions. They may not perform in other circumstances.
How to test the model with information from a variety of market regimes. Stable performances across conditions suggest that the model can capture robust patterns, rather than limiting itself to a single regime.
Utilizing these methods by applying these techniques, you will be able to better understand and mitigate the risk of overfitting and underfitting in an AI stock trading predictor, helping ensure that the predictions are accurate and applicable in real-world trading environments.
