When in 2019 I started this blog, I allowed myself to be a little controversial by writing "AI will change the world more than the industrial revolution." Of course, prediction is very difficult, especially if it's about the future (Niels Bohr), but recent developments in machine learning have made me...
Preparing your data for machine learning is not a task that most AI professionals miss. Data are of different quality, most often they require very thorough analysis, sometimes manual review, and certainly selection and initial preprocessing. In the case of classification tasks, the division of a dataset into classes may...
Until recently, a large part of the key concepts in the field of artificial intelligence was not so clearly defined. Some of them, such as Deep Learning, were even referred to as "buzzwords", term used mainly by marketing and not strictly translated into scientific areas. Now, the basic concepts seem...
If I had to indicate one algorithm in machine learning that is both very simple and highly effective, then my choice would be the k-nearest neighbors (KNN). What's more, it's not only simple and efficient, but it works well in surprisingly many areas of application. In this post I decided...
If you are a Python programmer and use the AWS and Anaconda environments, sooner or later you will come across the need to run a Python script as a cron process on Amazon Linux in the Anaconda environment. This shouldn't be difficult, right? Hmmm, unfortunately it is. Because I spent...
Do you like statistics? There is a high probability ;-) that you don't. But don't worry, statistics are not my strong point either. All in all, it's hard to say why most people shun statistics, but I feel that many statistical issues are not entirely intuitive. Just reach for the...
One of the first problems faced by AI students is how to build a development environment for machine learning. This is an ungrateful issue because there are many methods and tools available and sometimes you simply don't know which to choose and where to start. Added to this are the...
Today I would like to present an example of using logistic regression and Keras for the binary classification. I know that this previous sentence does not sound very encouraging ;-) , so maybe let's start from the basics. We divide machine learning into supervised and unsupervised (and reinforced learning, but let's...
