AI predictors of stock prices are prone to underfitting as well as overfitting. This can affect their accuracy and generalisability. Here are ten tips to assess and mitigate these risks in the case of an AI-based predictor for stock trading.
1. Analyze Model Performance Using Sample or Out of Sample Data
Reason: High precision in samples, but low performance of the samples suggest that the system is overfitting. In both cases, poor performance could indicate that the system is not fitting properly.
What should you do: Examine whether your model is performing consistently using both the in-sample as well as out-of-sample data. A significant performance decline out of sample suggests a likelihood of overfitting.
2. Make sure you check for cross validation.
What is the reason? Cross-validation enhances the ability of the model to be generalized by training and testing it with different data sets.
Check that the model is using the kfold method or a cross-validation that is rolling. This is especially important when dealing with time-series data. This gives a better estimate of the model’s real-world performance, and also identify any signs of under- or overfitting.
3. Calculate the complexity of model in relation to the size of the dataset
The reason: Complex models for small data sets can easily remember patterns, resulting in overfitting.
How: Compare model parameters and size of the dataset. Simpler models, such as linear or tree-based models, tend to be preferable for smaller datasets. However, complex models, (e.g. deep neural networks) require more data to avoid being too fitted.
4. Examine Regularization Techniques
Why? Regularization penalizes models that have excessive complexity.
How: Ensure that your model is using regularization methods that match its structure. Regularization imposes constraints on the model, and also reduces its dependence on fluctuations in the environment. It also enhances generalization.
Review Feature Selection Methods
Why Included irrelevant or unnecessary elements increases the chance of overfitting as the model may learn from noise, rather than signals.
How do you evaluate the feature selection process and ensure that only the most relevant features are included. Methods for reducing the number of dimensions, like principal component analysis (PCA) can help in removing unnecessary features.
6. Consider simplifying tree-based models by using methods such as pruning
Why: Tree-based model like decision trees, are prone to overfit if they become too deep.
How do you confirm if the model simplifies its structure by using pruning techniques or other method. Pruning can help you remove branches that cause noise instead of patterns of interest.
7. Model Response to Noise
Why is that models with overfits are sensitive to noise, and even slight fluctuations.
How to: Incorporate tiny amounts of random noise into the input data. Observe how the model’s predictions drastically. While models that are robust can handle noise without significant performance change, overfitted models may react unexpectedly.
8. Model Generalization Error
Why: The generalization error is a measure of how well a model can predict new data.
Determine the number of errors in training and tests. A large gap indicates the overfitting of your system while high test and training errors indicate underfitting. It is best to aim for an even result in which both errors are low and are close.
9. Check the Model’s Learning Curve
Why? Learning curves can provide a picture of the relationship between the model’s training set and its performance. This is useful for to determine if an model was over- or underestimated.
How do you plot learning curves. (Training error and. the size of data). In overfitting, training error is low while validation error remains high. Underfitting has high errors in both validation and training. The curve must indicate that both errors are decreasing and increasing with more data.
10. Check for stability in performance across various market conditions
Why: Models with a tendency to overfitting can perform well under certain market conditions, but do not work in other.
What can you do? Test the model against data from a variety of markets. Stable performance in different market conditions suggests that the model is capturing strong patterns, rather than being over-fitted to a particular regime.
Utilizing these techniques you can reduce the risks of underfitting and overfitting, when using the stock-trading prediction system. This helps ensure that the predictions made by this AI are applicable and reliable in real-life trading environments.
