#GoogleIO2021 was last week and it's a lot of content to read/watch!

I'll post summaries of all the ML talks and help you be up to date

Let's start with my talk with @kempy about how #TFHub and how people are using it on the real world



[5 min]

1/7🧡
Having access to high quality models enables developers to solve their problems!

This makes ML more accessible to everyone and helps the society with it, like:

β€’ Defend forests from illegal hunting
β€’ Studying & protecting whales
β€’ Blocking spam
β€’ Helping farmers

2/7🧡
TensorFlow Hub has models for all the ML domains such as Image, Text, Audio and Video

For image, this tutorial can get you started with Transfer Learning. It does some cool tricks with the data and the final model is ready for on-device deployment

3/7🧡
On the Text domain, you can find models for text classification and text embeddings in multiple languages.

You can follow this BERT tutorial that show how to use a State of the Art model with text preprocessing and easy experimentation

4/7🧡
Audio is a very interesting domain
We usually think about understanding speech as the main task but it can do much more like audio classification and pitch detection

If you want to do Transfer Learning for audio classification, follow this tutorial tensorflow.org/tutorials/audi…

5/7🧡
The Video domain is more than a combination of a bunch of images. One cool example of ML for Video is doing activity recognition

This tutorial can give you a good start on how to do it: tensorflow.org/hub/tutorials/…

6/7🧡
These are just some examples of how #TFHub can help you!

I've been trying the new TensorFlow Decision Forest (TF-DF) library today and it's very good!

Not only the ease of use but also all the available metadata, documentation and integrations you get!

Let me show you some of the cool things I've learned so far...

[5 min]

1/11🧡
TensorFlow Decision Forests have implemented 3 algorithms:

β€’ CART
β€’ Random Forest
β€’ Gradient Boosted Trees

You can get this list with tfdf.keras.get_all_models()

All of them enable Classification, Regression and Ranking Tasks

2/11🧡
CART or Classification and Regression Trees is a simple decision tree. 🌳

The process divides the dataset in two parts
The first is used to grow the tree while the second is used to prune the tree

This is a good basic algorithm to learn and understand Decision Trees

Machine learning goes beyond Deep Learning and Neural Networks

Sometimes a simpler technique might give you better results and be easier to understand

A very versatile algorithm is the Decision Forest
🌴🌲🌳?

What is it and how does it work?
Let me tell you..

[7 min]

1/10🧡
Before understanding a Forest, let's start by what's a Tree

Imagine you have a table of data of characteristics of Felines. With features like size, weight, color, habitat and a column with the labels like lion, tiger, house cat, lynx and so on.

2/10🧡
With some time, you could write a code based on if/else statements that could, for each a row in the table, decide which feline it is

This is exactly what a Decision Tree does
During its training it creates the if/elses

Today it's my 6 year Google anniversary!

I started as an android developer πŸ“±πŸ€– and today I'm an ML developer πŸ§ πŸ€–

I learned a lot of technical stuff (A LOT!), but there's much more than that.

Let me tell you some of the things I learned...

1/11🧡
Being the big fish 🐳 on a small pound is cool, but you may run out of air.

Starting at this job meant becoming a tiny fish 🐠 in a big pound!

And here is where the growth opportunities are!

2/11🧡
Working with smarter people than you is sometimes very hard for your ego!
There's a lot of impostor syndrome in the beginning.

But that's a big chance to learn what these smarter people do that you can adapt and grow as bigger fish 🦈.

Sometimes you need to build a Machine Learning model that cannot be expressed with the Sequential API

For these moments, when you need a more complex model, with multiple inputs and outputs or with residual connections, that's when you need the Functional API!

[2.46 min]

1/8🧡
The Functional API is more flexible than the Sequential API.

The easiest way to understand is to visualize the same model created using the Sequential and Functional API

2/8🧡
You can think of the Functional API as a way to create a Directed Acyclic Graph (DAG) of layers while the Sequential API can only create a stack of layers.

Functional is also known as Symbolic or Declarative API

This week, let's talk about model building a little.

In the TensorFlow world, the simplest way of building a model is with a Sequential model.

But what is it and how to do it?

[4 minutes]

1/9🧡
First, let's go over some basics.

The goal here is to build a Neural Network, or in other words, create a set of neurons, distributed in layers and connected by weights.

Each Layer applies some computation on the values or tensors it receives.

2/9🧡
The simplest way to create this NN is to just do a plain stack of layers where each layer has exactly one input and one output.

This is exactly what a Sequential model does
