Robust AI algorithms are able to maintain their performance even when faced with noisy, incomplete, or adversarial data. This is an important consideration for AI algorithms that are deployed in real-world applications.Cross-validation is a technique for evaluating the performance of an AI algorithm on unseen data. This is done by dividing the data into a number of folds, and then training the algorithm on all but one of the folds. The algorithm is then tested on the fold that was not used for training. This process is repeated for each fold, and the average performance of the algorithm is calculated.Regularization: Regularization is a technique for preventing overfitting.

Evaluation and improvement of AI algorithm performance and accuracy utilising measures including accuracy, precision, recall, F1-score, ROC curve, cross-validation, hyperparameter tweaking, feature selection, and regularisation is the fifth phase in AI algorithm creation.

For proper evaluation, first of all the dataset needs to be split into training, validation and test set. Training set is used to train the model , validation set is used to optimise and fine tune the model that is trained. And for the final evaluation of model’s performance test set is being used on unseen data which was neither used for train or optimise phase. This set up using the right metrics based on the problem statement would provide a realistic assessment of how well the model generalised without over or under fit.

AI evaluation and improvement are integral steps in the AI algorithm design process.
