First steps with TensorFlow.js

Aral Roca

I would like to do more articles explaining a little bit about all the machine learning and deep learning basics. I’m a beginner in this area, but I’d like to explain soon these concepts to create some interesting AI models.

Nevertheless, we don’t need a deep knowledge about machine learning to use some existing models. We can use some libraries like Keras, Tensorflow or TensorFlow.js. We are going to see here how to create basic AI models and use more sophisticated models with TensorFlow.js.

Although it’s not required a deep knowledge, we are going to explain few concepts.

What is a Model?

Or maybe a better question would be: ‘What is the reality?’. Yes, that’s quite complex to answer… We need to simplify it in order to understand it!

A way to represent a part of this simplified “reality”  is using a model. So; there are infinity kind of models: world…

The power has just gone out in mission control. I look to Jim McClure, operations manager at the Space Flight Operations Facility, and he assures me that everything is fine. A power outage like this hasn’t happened at NASA’s Jet Propulsion Laboratory in nearly eight years, and while it’s only been out for a few seconds, the Deep Space Network is disconnected and NASA has temporarily lost contact with Cassini, the nearly 20-year-old space probe in orbit around Saturn, as well as all spacecraft beyond the moon.

We’re standing in JPL’s mission control, known simply as the Dark Room to those who work here. Five men and women are glued to their screens, the artificial pink-and-white glow highlighting their faces. I’ve been here twice before, but I have never seen this many people running the consoles. The operators…
