Survival analysis is a popular statistical method to investigate the expected duration of time until an event of interest occurs. We can recall it from medicine as patients' survival time analysis, from engineering as reliability analysis or time-to-failure analysis, and from economics as duration analysis. Besides these disciplines, survival analysis can also be used by HR … [Read more...] about Hands-on Survival Analysis With Python

The Creative Side Of Vision Transformers
What's creativity? The most accredited definition is the following: “Creativity is the capability of creating novel things” It is considered one of the most important and irreplaceable peculiarities of humankind. But if this is such a special characteristic, it would be impossible for a neural network to imitate it, isn't it? Well, not exactly. Today we are facing some … [Read more...] about The Creative Side Of Vision Transformers
Building A Face Recognition System Using Scikit Learn In Python
What’s face recognition? Face recognition is the task of comparing an unknown individual’s face to images in a database of stored records. The mapping could be one–to–one or one–to–many, depending on whether we are running face verification or face identification. In this tutorial, we are interested in building a facial identification system that will verify if … [Read more...] about Building A Face Recognition System Using Scikit Learn In Python
Data Scientist’s Guide To Efficient Coding In Python
In this article, I wanted to share a few tips for writing cleaner codes that I have absorbed in the last year — mainly from pair programming. Generally speaking, including them as part of my everyday coding routine has helped me generate supreme quality Python scripts, that are easily maintainable and scalable over time. Ever thought why senior developer’s code look so … [Read more...] about Data Scientist’s Guide To Efficient Coding In Python
How To Do Bayesian A/B Testing At Scale
If you’ve read my previous post, you already know why I think you should move to Bayesian A/B testing. In this post, I give a short overview over the statistical models behind Bayesian A/B tests, and present the ways we implemented them at Wix.com — where we deal with a massive scale of A/B tests. I wrote some practical examples in Python along this post. You can easily … [Read more...] about How To Do Bayesian A/B Testing At Scale
Why You Should Switch To Bayesian A/B Testing
What is A/B Testing? Almost everyone hated learning statistics (well, maybe except some statisticians). With all those distributions and critical values that we needed to memorize, we just ended up with a headache. You might have swore not to ever touch the subject again; that is, until you had to analyze an A/B test. A/B testing is the “fun” name … [Read more...] about Why You Should Switch To Bayesian A/B Testing
How Can You Tell If Your Recommender System Is Any Good?
It’s an exciting time to be working on recommender systems. Not only are they more relevant than ever before, with Facebook recently investing in a 12 trillion parameter model and Amazon estimating that 35% of their purchases come from recommendations, but there is a wealth of powerful, cutting edge techniques with code available for anyone to try. So the … [Read more...] about How Can You Tell If Your Recommender System Is Any Good?
How Does An AI Imagine The Universe?
What’s out there? In this vast, infinite and inconceivable universe… Stars, planets, nebulae and celestial bodies are colliding, orbiting, being born and dying since the dawn of time. Humans have always looked up to the sky with fascination, imagining fantastic worlds and unreachable galaxies, and this has prompted mankind to use science to better understand the … [Read more...] about How Does An AI Imagine The Universe?
Introduction To AI For Social Good
AI for Social Good — a relatively new research field at the intersection of AI and a number of other fields. Source “Whenever I hear people saying AI is going to hurt people in the future I think, yeah, technology can generally always be used for good and bad and you need to be careful about how you build it … if you’re arguing against AI then you’re arguing against … [Read more...] about Introduction To AI For Social Good
Self-Supervised Learning In Vision Transformers
Anyone who has ever approached the world of machine learning has certainly heard of supervised learning and unsupervised learning. These are in fact two important possible approaches to Machine Learning that have been widely used for years. Only recently, however, has there been an explosion of a new term, Self-Supervised Learning! But let’s get there step by step and look at … [Read more...] about Self-Supervised Learning In Vision Transformers
