The basic principle of robotics and AI

-

Artificial intelligence applied to robotics development requires a different set of skills from you, the robot designer or developer. You may have made robots before. You probably have a quadcopter or a 3D printer. The familiar world of  Proportional Integral Derivative  ( PID ) controllers, sensor loops, and state machines must give way to artificial neural networks, expert systems, genetic algorithms, and searching path planners. We want a robot that does not just react to its environment as a reflex action, but has goals and intent—and can learn and adapt to the environment. We want to solve problems that would be intractable or impossible otherwise. Robotics or a robotics approach to AI—that is, is the focused learning about robotics or learning about AI? about how to apply AI tools to robotics problems, and thus is primarily an AI using robotics as an example. The tools and techniques learned will have applicability even if you don’t do robotics, but just apply AI to

The Tableau Applications Suite

Introduction and Getting Started with Tableau

Tableau was created to empower people to analyze their data regardless of the level of their technical know‐how. At the core of Tableau is VizQL, an innovative visual query language that translates mouse inputs such as drag‐and‐drop into database queries. This allows the user to quickly find insights in their data and to share the results with others.



Crucially, it is not necessary to know what you are looking for or how you want to present your findings. Instead, with Tableau, you can immerse yourself in data. Through visual analysis, you will be able to unearth patterns and relationships in your data that you might not have known existed. In this regard, Tableau is different from other tools, which often require you to know beforehand in what form you want to display your data.

The purpose of this chapter is to introduce you to the different products that make up the Tableau application suite, the Tableau user interface, and to how Tableau processes your data. We will also introduce the sample dataset that is used throughout this book and provides a first glimpse of the possibilities that Tableau gives you for creating data visualizations and get more from the tableau certification

By the end of this chapter you will be able to:
  • Install Tableau on your computer.
  • Identify data that is suitable for analysis.
  • Create your first data visualization in Tableau.

Some readers may have bought this book because they already have one or more Tableau products installed on their machine and would like to jump right in and learn how to use them. But for those who are not so familiar with the different Tableau products, here is a quick overview:

           The tableau applications Suite



Tableau Desktop Tableau Desktop is an application for Windows and Mac, appreciated by both analysts and business users. In Tableau Desktop, you can connect to flat files (such as Excel and CSV files) and save your workbooks to your local hard drive. To tap into an organization's IT infrastructure, you can also use Tableau Desktop to connect to a host of different database solutions, and you can share your workbooks via Tableau Server or the cloud‐based Tableau Online.

Tableau Prep Tableau Prep is the latest addition to the Tableau product suite and is designed to help you prepare your data before you analyze it in Tableau Desktop. The visual interface allows you to quickly merge differently formatted datasets, clean the data, and unify the level of aggregation. Tableau Prep fits seamlessly into your analysis workflow.

Tableau Server Tableau Server is a platform for data analysis and is used by small family‐run businesses and large Fortune 500 companies alike. It is intended for the organization‐wide provision of data visualizations and dashboards that can be viewed in a browser and are frequently embedded into the organization's intranet.

Tableau Online Tableau Online is a Tableau‐hosted solution for storing and deploying dashboards. It provides similar functionality to Tableau Server but is a cloud‐based service. No purchase and maintenance of server hardware are necessary here.

Tableau Public Tableau Public is a hosting service for the publication of data visualizations to the web. It is used by newsrooms and bloggers but also by companies, research institutes, governmental bodies, and non‐governmental organizations that aim to get their data stories into the public eye. The interactive visualizations can be viewed in the browser directly on the Tableau Public platform, or they can be embedded into blogs and websites.



Tableau Reader Tableau Reader is a free desktop application that allows you to open and interact with Tableau workbook files that have been created in Tableau Desktop. However, it is not possible to make any changes to the visualizations in Tableau Reader.

iOS 13 Features

In other words, iOS 13 should work on iPhone models from iPhone 6s onward, in addition to iPad mini 3 and later, the second-generation iPad Air and all later iPads, as well as the sixth-generation iPod touch. This was originally claimed by Israeli site The Verifier which in January said iOS 13 would drop compatibility for the iPhone 5s through iPhone 6s models. The reported removal of iOS 13 support for the iPhone SE and iPhone 6 models is very questionable because major iOS software updates are typically optimized for Apple’s processor models, not specific devices. If iOS 13 is indeed going to drop support for all the iPhone models with the Apple A8 chip, such as the iPhone 6/Plus range, then it will make no sense whatsoever to also remove compatibility for iPhone SE, which runs the newer Apple A9 chip and is still being manufactured in India. Join the Swift couse Equally puzzling is alleged support for the sixth-generation iPod touch because that device sports the same A8 pr

Data Science and Machine Learning

Data Science and Machine Learning: Broad and Narrow Terminology First of all, data science is really a broad, overarching category of technology that encompasses many different types of projects and creations. Machine learning has been one of the biggest advancements in the history of computing, and now it is believed to be capable of taking on significant roles in the field of big data and analytics. Big data analysis is a huge challenge from the perspective of businesses. For example, activities such as making sense of huge volumes of varied data formats, data preparation for analytics and filtering redundant data can consume a lot of resources. Hiring data scientists and specialists is an expensive proposition and not within every company’s means. Experts believe that machine learning is capable of automating many tasks related to analytics – both routine and complex. Automating machine learning can free up a lot of resources that can be used in more complex and innovative job
