Neural networks mirror the behaviour of the human brain, enabling computer programmes to recognise patterns and solve common problems in the fields of artificial intelligence, machine learning and deep learning.

Nowadays neural networks are used frequently for various tasks such as text translation, face identification, recognising speech or handwritten text, control robots and autonomous vehicles, image recognition, image classification and many more.

If neural networks are becoming so popular it would be good to create them in an easy way and the Axon library which is built on top of Nx allow to do that in Elixir.

In episode 94 of Thinking Elixir, we talk with Tobias Pfeiffer about his popular performance benchmarking tool Benchee. We learn about why he created it, what’s special about it, and the big features in the latest release. It was 2 years between this release and the previous one. Tobi talks openly about the technical challenges that compounded with personal challenges, feelings of obligation, anxiety, and the drive for perfection. As developers, many of us struggle with these same issues and it helps just hearing that we’re not alone.

It inlines bindings into the query, so it is easy to copy-paste logged SQL and run it in any IDE for debugging without manual transformation of common elixir terms to string representation (binary UUID, DateTime, Decimal, json, etc). Also, it highlights db time to make slow queries noticeable. Source table and inlined bindings are highlighted as well.
