Exploring Nx and Tensors Beyond Machine Learning in Elixir

BEAM Machine Learning Nx Phoenix LiveView

The article presents an overview of the Nx library in Elixir, highlighting its capabilities to handle numerical computations efficiently, even for operations that aren't related to machine learning. Jason Stiebs explains how Nx allows developers to describe various numerical operations using tensors, which can be processed optimally on CPUs/GPUs. Although the BEAM virtual machine, which Elixir runs on, is traditionally not geared towards mathematical tasks, Nx changes that by providing features to manipulate one-dimensional vectors or multidimensional arrays with ease. Jason walks readers through different examples, starting with simple math on integers and lists, progressing to more complex operations and higher dimensional tensors. With Nx, even developers unfamiliar with numerical programming can capitalize on performance benefits for everyday mathematical tasks. The flexibility of Nx also paves the way for a variety of other projects beyond machine learning, including data manipulation and image processing. The article serves as both a guide for beginners to get started with Nx by setting up an Elixir script or Livebook, and as an invitation to Elixir developers to consider using Nx for various computational needs.

Handling Elixir Project Development Post Ecto Dump

Mark Ericksen offers a solution for developers who have deleted old migration files and are now facing a chicken-and-the-egg problem when bootstrapping a new server or setting up a clean database. By adding a step in the mix.exs file's ecto.setup task and using the ecto.load command with specific flags, developers can safely continue development with a structure.sql file generated from mix ecto.dump and without the older migrations.
