Essential Python:

**Practical Deep Learning** is designed to meet the needs of competent professionals, already working as engineers or computer programmers, who are looking for a solid introduction to the subject of deep learning combined with sufficient practical, hands-on training to enable them to start implementing their own deep learning systems.

The course is based on the Python programming language and makes extensive use of the TensorFlow machine learning framework and the Keras neural network API, as well as Numpy, Matplotlib, Pandas, Scikit-learn, and TensorBoard. Although based on TensorFlow and Keras, the principles and concepts taught in this training course would be equally applicable in any deep learning library or framework.

**Practical Deep Learning** is delivered as a 5-day public face-to-face training course. It is recommended that all 5 days are attended, however those who already know Python AND understand how to use Numpy and Jupyter Notebook can opt to skip day 1 and start on day 2. Please review the course pre-requisites and discuss with Doulos if you are considering this option.

Workshops comprise approximately 50% of class time and are based around carefully designed hands-on exercises to reinforce learning.

### Why choose this particular course?

There are plenty of materials and training options out there for machine learning and deep learning, everything from e-books and blogs through online tutorials and MooCs to the formal courses offered by universities and corporations. Some of these are excellent, and they each have their place. The challenge is knowing where to start and having the time to research and study what you need to know. As a specialist provider of technical training, Doulos has been able to condense the essential knowledge and skills you need to get started with deep learning into this one 5-day training course.

### Who should attend?

Engineers, programmers, or other people with a technical or mathematical background who want a comprehensive, hands-on introduction to the subject of deep learning.

### What will you learn?

- Day 1 - Python Primer
- Basic Python programming
- How to use Numpy and Matplotlib in the context of deep learning

### What this course is not!

This course is not a high-level overview of deep learning for managers, business developers, or end users of machine learning technology, although attendees will certainly gain an excellent overview of deep learning by attending this course. This is a detailed, hands-on course.

This is not a course in machine learning or artificial intelligence as such, but in deep learning. Deep learning is one specific branch of machine learning, which is a branch of artificial intelligence.

This is not a course in mathematics, statistics, or data science. This course assumes you already have the necessary mathematical background (see prerequisites below).

This course is not for professional mathematicians or machine learning researchers. It is for programmers and implementers.

### Pre-requisites

Attendees should be experienced and competent in at least one object-oriented programming language (e.g. Python, Ruby, C++, C#, Java, or SystemVerilog). Candidates who are unfamiliar with object-oriented programming may still attend if they are very confident of their programming skills.

**Attendees who are unfamiliar with Python will need to attend all 5 days**. Attendees who are already familiar with Python, Numpy and Jupyter Notebook may skip the first day, but please discuss this option with Doulos if you are considering it.

Attendees should be familiar with the following mathematical concepts:

- Continuous functions of one or more variables, linear and non-linear functions, exponential functions
- Very basic differential calculus - derivatives and partial derivatives
- Very basic statistics - mean, standard deviation, variance, probability, histograms, normal distribution
- Basic linear algebra - vectors, matrices, summation, dot product

Attendees do **not** need a university degree in mathematics.
The emphasis of this course is on practical computer programming, not on mathematical theory.
This course does not require the attendee to write or solve mathematical equations, nor does it require the attendee to read or understand any mathematical proofs.
However, attendees do need a willingness to immerse themselves in what is essentially a mathematical topic.

### Training materials

Doulos training materials are renowned for being the most comprehensive and user friendly available. Their style, content and coverage is unique, and has made them sought after resources in their own right. You get to keep the following materials at the end of the course:

- A fully indexed set of class notes that form a complete reference manual
- A set of Jupyter Notebooks containing working examples of deep neural networks using TensorFlow and Keras
