AI stock trading predictors are vulnerable to underfitting and overfitting. This could affect their accuracy, and even generalisability. Here are 10 ways to evaluate and reduce these risks when using an AI model for stock trading:
1. Analyze Model Performance with In-Sample or Out-of Sample Data
Why: High accuracy in samples but poor performance out of samples suggests that the system is overfitting. In both cases, poor performance could indicate that the system is not fitting properly.
What can you do to ensure that the model is performing consistently over both in-sample (training) as well as out-of-sample (testing or validation) data. Performance drops that are significant out of samples indicate that the model is being overfitted.
2. Verify that the Cross-Validation is used
What is the reason? Cross-validation guarantees that the model is able to generalize when it is developed and tested on different subsets of data.
How to confirm if the model uses cross validation using k-fold or rolling. This is vital especially when dealing with time-series. This will provide a more accurate idea of the model’s real-world performance, and can detect any indication of over- or underfitting.
3. Evaluate Model Complexity Relative to the Size of the Dataset
Why: Overly complex models for small data sets can easily memorize patterns, leading to overfitting.
How can you tell? Compare the number of parameters the model is equipped with in relation to the size of the dataset. Models that are simpler (e.g., trees or linear models) are usually preferable for smaller data sets, whereas complex models (e.g., deep neural networks) require larger data in order to keep from overfitting.
4. Examine Regularization Techniques
The reason why: Regularization (e.g., L1, L2, dropout) reduces overfitting by penalizing overly complex models.
How: Use regularization methods that fit the structure of the model. Regularization helps reduce noise sensitivity while also enhancing generalizability and limiting the model.
Review feature selection and Engineering Methods
What’s the reason? The inclusion of unrelated or overly complex features could increase the chance of an overfitting model, because the model could learn from noise rather than.
How to: Go through the feature selection procedure and ensure that only relevant choices are chosen. Techniques to reduce dimension, such as principal component analysis (PCA) can simplify the model by removing irrelevant aspects.
6. Find techniques for simplification, such as pruning in tree-based models
Reason: Tree models, including decision trees, can be prone to overfitting if they become too deep.
How: Verify that the model is using pruning or a different method to simplify its structure. Pruning is a way to eliminate branches that contain noise and do not provide meaningful patterns.
7. Model Response to Noise
Why is that models with overfits are prone to noise and even minor fluctuations.
To determine if your model is robust Add small amounts (or random noise) to the data. Then observe how the predictions of the model shift. The models that are robust will be able to deal with tiny amounts of noise without impacting their performance. On the other hand, models that are too fitted may react in an unpredictable way.
8. Model Generalization Error
The reason is that generalization error is an indicator of the model’s ability to forecast on data that is not yet seen.
Examine test and training errors. A gap that is large could be a sign of overfitting. High training and testing errors could also be a sign of underfitting. Aim for a balance where both errors are small and comparable in value.
9. Check the Model’s Learning Curve
The reason: Learning curves demonstrate the relation between model performance and the size of the training set, that could be a sign of the possibility of over- or under-fitting.
How: Plotting the curve of learning (training errors and validation errors vs. the size of training data). Overfitting is characterised by low training errors and large validation errors. Underfitting is marked by high error rates for both. It is ideal to see both errors decreasing and converge as more data is gathered.
10. Evaluation of Stability of Performance in different market conditions
Why: Models with tendency to overfit can perform well under certain conditions in the market, but are not as successful in other.
Test the model with different market conditions (e.g. bear, bull, or market movements that are sideways). The model’s steady performance in all conditions suggests that it captures solid patterns without overfitting a particular regime.
Utilizing these methods can help you better assess and reduce the chance of overfitting and subfitting in an AI trading predictor.
