Artificial Intelligence By Example

Building a Reward Matrix – Designing Your Datasets

Experimenting and implementation comprise the two main approaches of artificial intelligence. Experimenting largely entails trying ready-to-use datasets and black box, ready-to-use Python examples. Implementation involves preparing a dataset, developing preprocessing algorithms, and then choosing a model, the proper parameters, and hyperparameters.

Implementation usually involves white box work that entails knowing exactly how an algorithm works and even being able to modify it.

In Chapter 1, Getting Started with Next-Generation Artifcial Intelligence through Reinforcement Learning, the MDP-driven Bellman equation relied on a reward matrix. In this chapter, we will get our hands dirty in a white box process to create that reward matrix.

An MDP process cannot run without a reward matrix. The reward matrix determines whether it is possible to go from one cell to another, from A to B. It is like a map of a city that...

Designing datasets – where the dream stops and the hard work begins

As in the previous chapter, bear in mind that a real-life project goes through a three-dimensional method in some form or other. First, it's important to think and talk about the problem in need of solving without jumping onto a laptop. Once that is done, bear in mind that the foundation of machine learning and deep learning relies on mathematics. Finally, once the problem has been discussed and mathematically represented, it is time to develop the solution.

First, think of a problem in natural language. Then, makemathematical description of a problem. Only then should you begin the software implementation.

Designing datasets

The reinforcement learning program described in the first chapter can solve a variety of problems involving unlabeled classification in an unsupervised decision-making process. The Q function can be applied to drone, truck, or car deliveries. It...

Logistic activation functions and classifiers

Now that the value of each location of L = {l1, l2, l3, l4, l5, l6} contains its availability in a vector, the locations can be sorted from the most available to the least available location. From there, the reward matrix, R, for the MDP process described in Chapter 1, Getting Started with Next-Generation Artifcial Intelligence through Reinforcement Learning, can be built.

Overall architecture

At this point, the overall architecture contains two main components:

  1. Chapter 1: A reinforcement learning program based on the value-action Q function using a reward matrix that will be finalized in this chapter. The reward matrix was provided in the first chapter as an experiment, but in the implementation phase, you'll often have to build it from scratch. It sometimes takes weeks to produce a good reward matrix.
  2. Chapter 2: Designing a set of 6×1 neurons that represents the flow of products at a...

Summary

Using a McCulloch-Pitts neuron with a logistic activation function in a one-layer network to build a reward matrix for reinforcement learning shows one way to preprocess a dataset.

Processing real-life data often requires a generalization of a logistic sigmoid function through a softmax function, and a one-hot function applied to logits to encode the data.

Machine learning functions are tools that must be understood to be able to use all or parts of them to solve a problem. With this practical approach to artificial intelligence, a whole world of projects awaits you.

This neuronal approach is the parent of the multilayer perceptron that will be introduced starting in Chapter 8, Solving the XOR Problem with a Feedforward Neural Network.

This chapter went from an experimental black box machine learning and deep learning to white box implementation. Implementation requires a full understanding of machine learning algorithms that often require fine-tuning.

A long established mantra of AI is that 'data is program and program is data'. Nowhere is this more true than in Reinforcement Learning (RL) and Deep Learning (DL). Here there is no established theory, just established Algorithms. The author's book steps in and by careful building of examples illustrates the underlying principles behind RL and DL. Each example is explained by [1] explaining the basis of the required data. [2] a textual understanding of the problem. [3] the development of a Python based program to solve the problem.I recommend this book to those who wish to gain a better insight into RL and DL and are willing to work towards it.

There is only one way to learn data science: With a solid understanding of the underlying theory, and by getting your hands dirty with real examples, data, and code. AI by example delivers exactly this mix, with examples that go beyond contrived toy boxes, and real code on git.While I wish the book had a chapter how to assure ML by scrutinizing data, debugging models, assessing model competence, and how to apply general software engineering principles as algorithms are derived from data, I understand that these issues concern a more experienced audience and would be out of scope for beginners. Still, I can see this book as a reference even for more experienced professionals, and it would be great to see these aspects considered in a third edition.That said, this book is equally for developers who need to learn how to build solid machine learning programs, project managers and consultants need to learn what ML is and is not capable of, as well as teachers and students who get a comprehensive overview of the key aspects of AI, along with their first hands-on experience training models.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
