Explainable ‘AI’ using Gradient Boosted randomized networks Pt2 (the Lasso)

[This article was first published on T. Moudiki's Webpage - R , and kindly contributed to R-bloggers ]. (You can report issue about the content on this page here ) Want to share your content on R-bloggers? click here if you have a blog, or here if you don't. This post is about LSBoost , an Explainable ‘AI’ algorithm which uses Gradient Boosted randomized networks for pattern recognition. As we’ve discussed it last week LSBoost is a cousin of GFAGBM ’s LS_Boost . In LSBoost , more specifically, the so called weak learners from LS_Boost are based on randomized neural networks’ components and variants of Least Squares regression models. I’ve already presented some promising examples of use of LSBoost based on Ridge Regression weak learners. In mlsauce ’s version 0.7.1 , the Lasso can also be used as an alternative ingredient to the weak learners. Here is a comparison of the regression coefficients obtained by using mlsauce ’s implementation of Ridge regression an...

Subscribe to get this delivered to your inbox . HORST FRIEDRICHS / ANZENBERGER / R​EDUX Limbo is too gentle a word. For many parents, the uncertainty around school reopenings amounts to a daily strain, as they contemplate another full season of juggling child care and career. Clear answers remain out of reach, for now, but here are three factors worth keeping in mind: 1. Not all kids will be able to follow the new pandemic rules. “K–12 students may generally be capable of doing what public-health experts ask, but not all of them, not everything, and not all the time,” Joe Pinsker explains. 2. Outdoor classes may be the solution. Olga Khazan reports: “Though it isn’t free of problems, learning outside might be the only way to provide parents with a break, kids with an adequate education, and teachers with protection from the...

It implements few mitigation strategies that could reduce the bias. It enables easy to use checks for fairness metrics and comparison between different Machine Learning (ML) models. Longer version Fairness in ML is a quickly emerging field. Big companies like IBM or Google developed some tools already (see AIF360 ) with growing community of users. Unfortunately, there aren’t many tools enabling to discover bias and discrimination in machine learning models created in R. Therefore, checking the fairness of the c...

The Atlantic Daily: The Real Implication of Trump’s Election Tweet

Every weekday evening, our editors guide you through the biggest stories of the day, help you discover new ideas, and surprise you with moments of delight. Subscribe to get this delivered to your inbox . (JIM WATSON / AFP / GETTY) 1. President Trump floated postponing the election, something he lacks the legal authority to do. The maneuver is not what it looks like on the surface, David A. Graham argues: “It’s more a means of preemptively contesting the outcome of an election he fears he will lose than trying to actually move it.” 2. Barack Obama spoke at the funeral of John Lewis, calling him “a founding father of that fuller, fairer, better America.”   Read the former president’s eulogy. And revisit Adam Serwer’s essay on the loss of the congressman and his fellow activist C. T. Vivian : “It is up to us to honor them, by continuing what they started, by sustaining the work of democracy as best we can.” 3. Herman Cain died of COVID-19. “In his ascent, Cain embodied...

Feature Leakage, and identifying it with Exploratory data analysis and Machine Learning

[This article was first published on R , and kindly contributed to R-bloggers ]. (You can report issue about the content on this page here ) Want to share your content on R-bloggers? click here if you have a blog, or here if you don't. On one of my projects, my team and I were tasked with building a mortgage leads generation model for a client — a quite standard project in the banking industry. The data shared with us, on the other hand, were not safe or fit for modelling straightaway: the data had been compiled from different sources, “possibly from different time periods” too. This might seem like an exceptional situation. In reality, however, it is all too common to acquire data from the client and take for granted their fitness for modelling. In our situation, the comment from our client meant that we were potentially looking at feature leakage. Feature and data leakage There are many examples of feature and data leakage, not only in corporate environments but also in c...
