Fairness in artificial intelligence models: how to mitigate discrimination in the presence of multiple sensitive attributes?

Let's suppose we have a machine learning model, 𝑓, that predicts the price of an insurance premium, Y, based on data that includes a sensitive attribute, such as gender. Discrimination may occur due to a statistical bias...

Policy Evaluation Under Markovian Noise Using The Online Bootstrap Inference Algorithm

Imagine being able to abstract the world in such a way that it is possible to quantitatively evaluate the benefit of taking certain actions over time. The good news is that this is not far-fetched, in fact one of the ways to do it is by using the theory around Reinforcement Learning (RL).

Diesel And Gasoline: Is The Country Ready To Abandon Regulated Pricing?

Would you be surprised if from one month to the next gasoline went up $2,000 pesos per gallon? The financial data would say no. In simple terms, we can imagine volatility as what we would consider normal movements.
