Course 806:
Introduction to Neural Networks and Deep Learning

(3 days)

 

Course Description

You do not need an extensive math background to understand neural network. In understandable steps, this course builds from a one node neural network to a multiple features, multiple output neural networks. All the steps are explained using working code to solve problems. After an understanding of how neural networks work and the parameters that control deep learning systems, Keras is introduced and used to simplify the building of deep learning neural networks. A convolutional deep learning neural network is built using Keras to show how deep learning is used in specialized neural networks. This course provides the necessary required background to understand ROI’s Time Series Analysis and Natural Language Processing courses.

Learning Objectives

In this course, attendees will:

  • Understand the context of neural networks and deep learning
  • Know how to use a neural network
  • Understand the data needs of deep learning
  • Have a working knowledge of neural networks and deep learning
  • Explore the parameters for neural networks

Prerequisites

Familiarity with running programs from the command line is helpful, but not necessary. Understanding the concept of a function is helpful, but not necessary. NOTE: The course developers, having worked through the math, strongly believe using the models do not require understanding of the math used to implement the model.

Who Should Attend

Anyone who wants to understand Neural Network and Deep Learning.
