Descripción de “Convolutional Neural Networks in TensorFlow (Coursera)”

If you are a software developer who wants to build scalable AI-powered algorithms, you need to understand how to use the tools to build them. This course is part of the upcoming Machine Learning in Tensorflow Specialization and will teach you best practices for using TensorFlow, a popular open-source framework for machine learning.

In Course 2 of the deeplearning.ai TensorFlow Specialization, you will learn advanced techniques to improve the computer vision model you built in Course 1. You will explore how to work with real-world images in different shapes and sizes, visualize the journey of an image through convolutions to understand how a computer “sees” information, plot loss and accuracy, and explore strategies to prevent overfitting, including augmentation and dropout. Finally, Course 2 will introduce you to transfer learning and how learned features can be extracted from models.

The Machine Learning course and Deep Learning Specialization from Andrew Ng teach the most important and foundational principles of Machine Learning and Deep Learning. This new deeplearning.ai TensorFlow Specialization teaches you how to use TensorFlow to implement those principles so that you can start building and applying scalable models to real-world problems. To develop a deeper understanding of how neural networks work, we recommend that you take the Deep Learning Specialization.

WHAT YOU WILL LEARN

– Handle real-world image data

– Plot loss and accuracy

– Explore strategies to prevent overfitting, including augmentation and dropout

– Learn transfer learning and how learned features can be extracted from models

Course 2 of 4 in the TensorFlow in Practice Specialization.

Course Syllabus

Week 1 – Exploring a Larger Dataset

In the first course in this specialization, you had an introduction to TensorFlow, and how, with its high level APIs you could do basic image classification, an you learned a little bit about Convolutional Neural Networks (ConvNets). In this course you’ll go deeper into using ConvNets will real-world data, and learn about techniques that you can use to improve your ConvNet performance, particularly when doing image classification! In Week 1, this week, you’ll get started by looking at a much larger dataset than you’ve been using thus far: The Cats and Dogs dataset which had been a Kaggle Challenge in image classification!

Week 2 – Augmentation: A technique to avoid overfitting

You’ve heard the term overfitting a number of times to this point. Overfitting is simply the concept of being over specialized in training — namely that your model is very good at classifying what it is trained for, but not so good at classifying things that it hasn’t seen. In order to generalize your model more effectively, you will of course need a greater breadth of samples to train it on. That’s not always possible, but a nice potential shortcut to this is Image Augmentation, where you tweak the training set to potentially increase the diversity of subjects it covers. You’ll learn all about that this week!

Week 3 – Transfer Learning

Building models for yourself is great, and can be very powerful. But, as you’ve seen, you can be limited by the data you have on hand. Not everybody has access to massive datasets or the compute power that’s needed to train them effectively. Transfer learning can help solve this — where people with models trained on large datasets train them, so that you can either use them directly, or, you can use the features that they have learned and apply them to your scenario. This is Transfer learning, and you’ll look into that this week!

Week 4 – Multiclass Classifications

You’ve come a long way, Congratulations! One more thing to do before we move off of ConvNets to the next module, and that’s to go beyond binary classification. Each of the examples you’ve done so far involved classifying one thing or another — horse or human, cat or dog. When moving beyond binary into Categorical classification there are some coding considerations you need to take into account. You’ll look at them this week!
