Alexandre

For the past 40 Cannes Film Festivals, Alexandre has been putting on a show.  As the head bartender at the Mondrian Cannes — the établissement formerly known as The Grand — he’s been mixing cocktails and charming post-premiere revelers since 1983. Alexandre — it’s always “Alexandre,” no last name, like Prince or Madonna — is, for festival regulars, as familiar and welcome a sight as Cannes’ iconic red carpet. With a tall, lean frame and sharp Gallic nose, he darts between tables like a more elegant…

Understanding this famous concept and how it impacts Machine Learning modelsPhoto by Piret Ilver on UnsplashThe bias-variance tradeoff is a fundamental and widely discussed concept in the area of Data Science. Understanding the bias-variance tradeoff is essential for developing accurate and reliable machine learning models, as it can help us optimize model performance and avoid common pitfalls such as underfitting and overfitting.Before defining it, it is necessary to define what is bias and variance separately.Photo by…

A quick guide to improve your organization skills and, consequently, your performance.Photo by Matthew Kwong on UnsplashFirst of all, I have a few simple questions for you:Have you ever been lost inside your own notebook, not knowing in which order the cells must be executed so that the code runs smoothly?During the development of a project, have you ever lost precious minutes or even hours trying to remember where an analysis that you had previously carried out was and what was the result of it?Have you ever had…

From clustering to algorithm: a journey in five stepsImage by Pauline AllouinWhile this article is more technical than my previous ones – one of which was how to successfully translate tech talk for management and users — it aims to explain a popular algorithm used in data science in simple words. Recently, I had to explain what clustering is to a curious, non-technical senior manager. He understood the whole concept of clustering and wanted to know more about how it was translated into an algorithm.The explanations in…

What is GA and how to use it to train Machine Learning models?Photo by Sangharsh Lohakare on UnsplashGenetic Algorithm (GA) is a type of natural computing algorithm, which are algorithms developed to try to solve problems by replicating phenomena and behaviors present in nature.There are several natural algorithms in the literature, such as Particle Swarm Optimization (PSO), which tries to mathematically simulate the social behavior of schools of fish or flocks of birds, and Ant Colony Optimization (ACO), which seeks to…

Three-dimensional simplicity: data, technology and people… and a tool to help along the wayImage by Alexandre AllouinIn a previous article, I advocated a simple way to communicate with executives or non-techies by illustrating any data initiative — from transforming your organization into a data-driven entity to developing a new data project — with just three dimensions: data, technology and people (“3D data story”) because, at the end of the day, that’s what it’s all about!“Life is really simple, but we insist on making…

A possible approach to reconcile data scientists and management behind the same objectivePhoto by Headway on UnsplashA common challenge for data teams is to bridge the gap between the need to transform an organization into a data-driven entity and successfully communicating it to management. I have read many papers on this topic, I have gone through different frameworks and I have been involved in many data projects. Often too complex for a non technical audience, these models or frameworks cannot always be presented as…

Yesterday, BOOM! Studios announced Once Upon a Time at the End of the World, “an epic post-apocalyptic series from New York Times bestselling and Eisner and Harvey Award winner, writer Jason Aaron.” Today, The Beat is pleased to exclusively reveal that the artist for the first five-issue arc of the ambitious creator-owned series will be Alexandre Tefenkgi (The Good Asian). Additional members of the creative team include colorist Lee Loughridge (The Good Asian) and letterer AndWorld Design. Once Upon a Time at the End of…
