Artificial Intelligence and Machine Learning Fundamentals

By: Zsolt Nagy

Overview of this book

Machine learning and neural networks are pillars on which you can build intelligent applications. Artificial Intelligence and Machine Learning Fundamentals begins by introducing you to Python and discussing AI search algorithms. You will cover in-depth mathematical topics, such as regression and classification, illustrated by Python examples. As you make your way through the book, you will progress to advanced AI techniques and concepts, and work on real-life datasets to form decision trees and clusters. You will be introduced to neural networks, a powerful tool based on Moore's law. By the end of this book, you will be confident when it comes to building your own AI applications with your newly acquired skills!

Lesson 6: Clustering

Activity 12: k-means Clustering of Sales Data

This section will detect product sales that perform similarly in nature to recognize trends in product sales.

We will be using the Sales Transactions Weekly Dataset from this URL:

https://archive.ics.uci.edu/ml/datasets/Sales_Transactions_Dataset_Weekly Perform clustering on the dataset using the k-means Algorithm. Make sure you prepare your data for clustering based on what you have learned in the previous lessons. Use the default settings for the k-means algorithm.

  1. Load the dataset using pandas.

    import pandas
pandas.read_csv('Sales_Transactions_Dataset_Weekly.csv')

  2. If you examine the data in the CSV file, you can realize that the first column contains product id strings. These values just add noise to the clustering process. Also notice that for weeks 0 to 51, there is a W-prefixed label and a Normalized label. Using the normalized label makes more sense, so we can drop the regular weekly labels from the data set.
