AI model of stock trading is prone to subfitting and overfitting, which can lower their precision and generalizability. Here are 10 suggestions on how to reduce and evaluate these risks when creating an AI stock trading prediction
1. Analyze Model Performance with In-Sample or Out-of Sample Data
Why is this? The high accuracy of the sample, but low performance outside of it suggests overfitting.
Make sure the model is performing consistently in both training and testing data. A significant drop in performance out of sample indicates a high likelihood of overfitting.
2. Make sure you are using Cross-Validation
What is the reason? Cross-validation enhances the ability of the model to be generalized by training and testing it on multiple data subsets.
What to do: Determine that the model has rolling or k-fold cross validation. This is important especially when dealing with time-series. This will provide a better understanding of how the model is likely to perform in real-world scenarios and reveal any tendency to over- or under-fit.
3. Calculate the complexity of the model in relation to the size of the dataset
The reason: Complex models with small datasets could quickly memorize patterns, leading to overfitting.
What can you do? Compare the size and number of the model's parameters against the dataset. Simpler (e.g. linear or tree-based) models are generally more suitable for small data sets. Complex models (e.g. neural networks, deep) require large amounts of information to avoid overfitting.
4. Examine Regularization Techniques
What is the reason? Regularization (e.g. L1 Dropout, L2) reduces the overfitting of models by penalizing those that are too complex.
How: Make sure that the method of regularization is compatible with the model's structure. Regularization helps reduce noise sensitivity, improving generalizability and constraining the model.
Review the selection of features and engineering techniques
What's the reason? The inclusion of unrelated or overly complex features could increase the risk of an overfitting model because the model could be able to learn from noise, instead.
How: Assess the process of selecting features to ensure only relevant features are included. Dimensionality reduction techniques, like principal component analysis (PCA) can be used to eliminate features that are not essential and simplify the model.
6. For models based on trees, look for techniques to simplify the model, such as pruning.
Why: If they are too complicated, tree-based modeling like the decision tree, is susceptible to be overfitted.
How do you confirm that the model employs pruning techniques or other methods to simplify its structure. Pruning helps remove branches that capture more noise than patterns that are meaningful which reduces the likelihood of overfitting.
7. Check the model's response to noise in the Data
Why are models that are overfitted sensitive to noise and small fluctuations in data.
How do you introduce tiny amounts of random noise to the input data, and then observe if the model's predictions change drastically. The model with the most robust features should be able handle minor noises without causing significant shifts. However the model that has been overfitted could react unpredictably.
8. Look for the generalization mistake in the model
What is the reason? Generalization errors reveal how well models are able to anticipate new data.
Find out the differences between training and testing errors. A wide gap indicates overfitting and both high test and training errors suggest underfitting. You should aim for an equilibrium result where both errors are low and are within a certain range.
9. Check the Learning Curve of the Model
Why: Learning Curves indicate the degree to which a model is either overfitted or underfitted by showing the relation between the size of the training set and their performance.
How to plot learning curves (training and validity error vs. the size of the training data). In overfitting the training error is low, whereas the validation error is very high. Underfitting has high errors both in validation and training. The curve should ideally indicate that both errors are decreasing and convergent with more data.
10. Analyze performance stability in different market conditions
Why: Models with an overfitting tendency can perform well under certain market conditions but fail in others.
How can we test the model? against data from a variety of markets. Stable performance indicates the model does not fit to any particular market regime, but instead detects reliable patterns.
By applying these techniques by applying these techniques, you will be able to better understand and mitigate the risk of underfitting or overfitting an AI prediction of stock prices and ensure that its predictions are reliable and valid in the real-world trading conditions.
