Hands-on Lab 5: Cleaning Data Estimated time needed: 45 minutes In this lab, first you will learn how to deal with inaccurate data, how to remove empty rows, and how to remove duplicated data. Next, you will learn how to change the case of text, how to change date formatting, and how to trim whitespace from data. Finally, you will learn how to use the Flash Fill feature and functions in Excel to help clean data. Software Used in this Lab The instruction videos in this course use the full Excel Desktop version as this has all the available product features, but for the hands-on labs we will be using the free ‘Excel for the web’ version as this is available to everyone. Although you can use the Excel Desktop software if you have access to this version, it is recommended that you use Excel for the web for the hands-on labs as the lab instructions specifically refer to this version, and there are some small differences in the interface and available features.

Introduction Convolutional neural networks (CNNs) emerged from the study of the brain’s visual cortex, and they have been used in image recognition since the 1980s. These studies of the visual cortex inspired the neocognitron, introduced in 1980,4 which gradually evolved into what we now call convolutional neural networks. An important milestone was a 1998 paper by Yann LeCun, Léon Bottou, Yoshua Bengio, and Patrick Haffner, which introduced the famous LeNet-5 architecture, widely used to recognize handwritten check numbers. Artificial Intelligence has been witnessing a monumental growth in bridging the gap between the capabilities of humans and machines. Researchers and enthusiasts alike, work on numerous aspects of the field to make amazing things happen. One of many such areas is the domain of Computer Vision. The agenda for this field is to enable machines to view the world as humans do, perceive it in a similar manner and even use the knowledge for a multitude of tasks such ...
