This involves training up to a certain point in time, testing on a subset of observations, training up to a further point in time, testing on a different subset of observations, and iteratively continuing this process on a panel data set. Sound familiar? This can be really frustrating to implement…

The emergence of bias in artificial intelligence (AI) presents a significant challenge in the realm of algorithmic decision-making. AI models often mirror the data on which they are trained. It can unintentionally include existing societal biases, leading to unfair outcomes. To overcome this issue, continuous monitoring and validation emerge as critical processes which are essential for ensuring that AI models function ethically and impartially over time. Understanding Bias in AI Bias in AI is dynamic and evolving with…

Select, check, and splitImage from PixabayFor most natural language processing (NLP) tasks, an important step is the selection of the datasets to train, validate, and evaluate a system. Machine translation is no exception, but has some specificities inherent to the multilinguality of the task.In this article, I explain how to select, check, and split datasets to make a machine translation system. I show with examples what are the most important properties of a dataset for machine translation and how to set the trade-off…

Is it possible to check if a string contains valid HTML using just SQL?Photo by Valery Sysoev on UnsplashChecking if a string is valid HTML is a really complex task, and isn’t something that can be accomplished trivially. In fact, writing a generic HTML string validator is a fairly involved task and isn’t something I hope to cover here. If you want to validate a string a containing valid XML/HTML in PostgreSQL, you should probably be using the XML data type or XML functions library.We would like to write a SQL query which…
