We all make predictions on a daily basis. We predict how long it will take us to get to the airport, when we will finish a task, or what our savings will be at the end of the month. These predictions may seem more trivial, but we also foresee extremely important scenarios, such as those related to public health or macroeconomic issues. We do this because putting ourselves in the future helps us make decisions in the present. Even though we know that predictions often end up being unfulfilled. Artificial Intelligence allows us to make far more reliable predictions, and, on many occasions, even accurate ones. Probably the best predictions we have ever been able to make. But as with any prediction, the value offered is never totally certain; the uncertainty involved in any estimate must be taken into account. Hence, we are actively introducing models for this kind of uncertainty during the development stage of our data-based products, such as the BBVA's app feature that shows the user their estimated balance at the end of the month. In the 2020 edition of the KDD Workshop on Machine Learning in Finance we have presented one of our latest solutions which uses our model with uncertainty to detect unexpected ‘spikes’ on balance series that may point to relevant changes in the customer’s situation or events that require immediate attention. To do that, our engine offers a prediction of what the customer’s balance could be for each of the following 30 days. However, instead of simply outputting a point estimate of the balance, the uncertainty model allows us to better understand the confidence in the balance prediction and to build other interesting applications. We also may send direct notifications to the customer in order to report relevant changes in their balance. In order to better explain how the model works, we have followed the predictions of a real case. In the figure below we can see how the engine generates the confidence bounds for each day of the month, that is, the ranges in which the series has a high probability of taking the future values. When the actual value is outside these bounds, we can say that a very unusual variation has occurred. Watch the full video. ![]() In this article our colleagues David Muelas, Luis Peinado and José A. Rodríguez tell more about this particular case and how the model works. Check it out! |

US Election: has the result forecast failed (again)? ![]() After the failures in polls and forecast models in the 2016 US election, leading public opinion research and media companies, such as FiveThirtyEight, set out to fix the issues for this year's election. However, although this time it can be said that they have predicted the results better, they still fall into the same errors of several of the country’s states and among some specific demographics. This PewResearch article reviews a number of these major errors, and launches some hypotheses and possible solutions. Among the most important aspects, it highlights the non-participation in the polls observed especially among Republican voters or the "shy Trump" phenomenon, by which their relatives are more reluctant to reveal their voting preferences. Also of concern is the under-representation in the polls of certain demographics, such as non-white college voters or hipanics. On the other hand, this FiveThirtyEight article is tremendously interesting to better understand how these forecast models work, which take data from polls but also from economic or demographic indicators, among others. ![]() Nate Silver, founder and editor in chief of FiveThirtyEight and the author of The Signal and the Noise: Why So Many Predictions Fail — But Some Don’t, explains in detail all the variables that are taken into account and what steps they take in building their election forecast, such as analyzing polls, and then combining them with demographic and economic data, or the simulation phase. |

![]() Quote of the month "Creative professions are some of the only fields that will withstand the rise of the robots and we need to do much more to ready ourselves, our companies, and our children for the creativity-focused future of work." Scott Belsky, Chief Product Officer at Adobe and founder of Behance In an article published in World Economic Forum, titled Creativity will be key to competing against AI in the future workforce - here's how, Belsky thinks about the changes driving AI and automation in the work of the future. The pandemic has accelerated this process and may offer us an opportunity to better understand some elements of this not so distant future. According to Belsky, the creativity-based jobs will be key in the future and he proposes to apply a new thinking to three critical areas: education, retraining and workplace tools. |
