Deep learning and TensorFlow

|

Cognitive Class training, MOOC (2020). This learning path presents the basic concepts of deep learning and TensorFlow with hands-on experience in solving problems. Throughout the training, TensorFlow is used in curve fitting, regression, classification and minimization of error functions. This concept is then explored in the deep learning world where TensorFlow is applied for backpropagation to tune the weights and biases while the neural networks are being trained.

Course 1: Deep learning fundamentals

Main topics:

  • Introduction to deep learning;
  • Deep learning models;
  • Additional deep learning models;
  • Deep learning platforms and libraries.

Course 2: Deep learning with TensorFlow

Main topics:

  • Introduction to TensorFlow;
  • CNN - Convolutional Neural Network;
  • RNN - Recurrent Neural Network;
  • Unsupervised learning.

Main topics:

  • What is a neural network?
  • Supervised learning with neural networks;
  • Why is deep learning taking off?

Week 2: Neural networks basics

Main topics:

  • Binary classification;
  • Logistic regression;
  • Gradient descent;
  • Derivatives with a computation graph;
  • Vectorizing logistic regression.

Week 3: Shallow neural networks

Main topics:

  • Neural network representation;
  • Computing a neural network's output;
  • Vectorizing across multiple examples;
