PYTHON NUMPY BROADCASTING (13/30)
This Python tutorial in French introduces you to Numpy and one of its essential features: broadcasting. This technique allows us to very easily perform mathematical operations between multiple N-dimensional Numpy arrays (nd arrays). Since Numpy is developed in C, it offers formidable execution speed, making Python incredibly simple and powerful.
With broadcasting, we can also extend the dimensions of N-dimensional Numpy arrays, when the initial dimension is equal to 1.

► Who am I?
I'm Guillaume Saint-Cirgue, a Senior Data Scientist with over 8 years of experience in the tech, aviation, robotics, energy, and smart factory sectors.
In 2019, I founded Machine Learnia to share my knowledge in the field of artificial intelligence. My goal is to explain in detail how machine learning and its algorithms work, while making these concepts accessible to everyone.
I firmly believe that simply skimming over the mathematical aspects of this field is not enough; It's essential to dive deep into it to stand out. This approach has already convinced more than 150,000 people, and those I train today are among the best in the industry.
