What the experts said
Reading the title alone or even the conclusions is insufficient when evaluating scientific publications about AI
When reading a scientific article, one must evaluate the validity of the distortions and the limits of the scientific study
Clinical and epidemiological data used by algorithms must be validated
Algorithms must be validated in practice in the sense of being applicable
The reproducibility of algorithms is an essential validation requirement
Understanding the algorithm used in artificial intelligence is indispensable
It is necessary to evaluate whether publications actually used artificial intelligence methods versus traditional statistical methods
In many cases, sufficient statistical performance can be achieved without artificial intelligence
Sample size is an indispensable consideration when evaluating AI algorithms
Geographic diversity in datasets affects algorithm performance
The dimension (size) of the algorithm matters for performance
When dealing with large amounts of data, more complex models may be needed
Data can change over time, which affects algorithm performance
Changes in measurement instruments can change the data and affect algorithm validity
The risk of complications when implementing algorithms in clinical practice must be assessed
Implementation in healthcare settings is not always straightforward
Privacy concerns exist in healthcare settings when implementing AI
Valid artificial intelligence requires maximum attention to the database composition and the proportion of diversity represented
External validation is necessary to properly evaluate AI algorithm performance
Core performance metrics for AI include sensitivity (recall), specificity, and positive predictive values
Performance metrics refer to the classic table of true/false positives and negatives, comparing observed values from the model to the gold standard or reference standard
Curve analysis is another dimension used to evaluate AI performance
Large language models represent an emerging technique in artificial intelligence
In the near future, systematic evaluation of AI publications will likely become more common due to the quantity of researchers and people of good will working in this area
