AI model of stock trading is susceptible to overfitting and subfitting, which could decrease their precision and generalizability. Here are 10 tips on how to mitigate and evaluate these risks when designing an AI stock trading prediction
1. Analyze Model Performance with In-Sample or Out-of Sample Data
Why: High accuracy in samples but poor performance out of samples suggests overfitting. In both cases, poor performance could be a sign of underfitting.
How do you determine if the model performs as expected with data from in-samples (training or validation) and those collected outside of the samples (testing). Significant performance drops out-of-sample indicate an increased risk of overfitting.
2. Make sure you check for cross validation.
Why: Cross validation helps to ensure that the model can be applicable by training it and testing on multiple data sets.
How: Confirm that the model uses k-fold cross-validation or rolling cross-validation especially in time-series data. This will give a better estimation of the model’s actual performance, and can detect any indication of over- or underfitting.
3. Evaluate Model Complexity Relative to the Size of the Dataset
Models that are too complicated on small data sets can easily be memorized patterns and lead to overfitting.
What can you do? Compare the size and number of model parameters to the dataset. Simpler (e.g. tree-based or linear) models are generally more suitable for smaller datasets. While complex models (e.g. neural networks deep) require large amounts of information to avoid overfitting.
4. Examine Regularization Techniques
Reason: Regularization helps reduce overfitting (e.g. dropout, L1, and L2) by penalizing models that are overly complex.
How to: Ensure that the model is using a regularization method that is suitable for its structural characteristics. Regularization can help constrain the model by decreasing the sensitivity of noise and increasing generalisability.
Review the Engineering Methods and Feature Selection
Why: The model could be more effective at identifying the noise than from signals when it is not equipped with unneeded or unnecessary features.
How: Assess the process of selecting features to ensure only relevant features are included. Techniques for reducing the amount of dimensions for example principal component analysis (PCA) helps to simplify and remove non-important features.
6. Look for Simplification Techniques Like Pruning in Tree-Based Models
Reasons Tree-based and decision trees models are prone to overfitting when they grow too large.
Check that the model is utilizing pruning or a different method to simplify its structure. Pruning can help remove branches which capture noisy patterns instead of meaningful ones. This helps reduce overfitting.
7. Model Response to Noise
Why are models that are overfitted sensitive both to noise and small fluctuations in data.
How to introduce tiny amounts of random noise into the data input and see whether the model’s predictions change drastically. The models that are robust will be able to deal with minor noises without impacting their performance, whereas models that have been overfitted could react in an unpredictable way.
8. Model Generalization Error
Why: Generalization error reflects the accuracy of models’ predictions based on previously unobserved data.
How to: Calculate the difference between mistakes in training and the tests. The large difference suggests the system is overfitted with high errors, while the higher percentage of errors in both testing and training suggest a system that is not properly fitted. Try to get an even result in which both errors have a low value and are similar.
9. Examine the Learning Curve of the Model
Why: Learning curves show the relation between model performance and training set size which can indicate over- or under-fitting.
How do you plot the learning curve: (Training and validation error vs. the size of the training data). Overfitting results in a low training error but a large validation error. Underfitting has high errors for both. In the ideal scenario the curve would show both errors declining and convergence as time passes.
10. Evaluation of Performance Stability under Different Market Conditions
Why: Models with tendency to overfit are able to perform well in certain market conditions, but fail in others.
Test the model with different market conditions (e.g., bear, bull, and sideways markets). A consistent performance across all conditions indicates that the model can capture robust patterns, rather than limiting itself to a single regime.
You can use these techniques to assess and manage risks of overfitting or underfitting in a stock trading AI predictor.
