      Introduction

      Machine learning has transformed the way a business and organization operates. It is important for every business to understand patterns and trends in complex data to succeed or maximize profits. This understanding is becoming a key attribute that a company must use to grow in a challenging environment. You can use Python, and the many underlying libraries and directories to derive some key insights about the data you have. The unique capabilities of the language make it easier for you to build some sophisticated algorithms and models that will allow you to stem some insights about the data set.

      From a business standpoint, machine learning can be used to understand how a customer thinks and behaves. Businesses can also use machine learning to predict the future profits or losses that the company may face. They can also use it to see when they should stock a specific product or when they should release a new product. Let us look at how a retailer can improve his or her sales through machine learning. The retailer can see when his or her customers purchase a specific product, and increase the stock for that product during that season. Walmart had realized that its customers wanted to purchase strawberries during a specific season, and the retailer increased the stock of strawberries in the store. This helped them improve on their profits. The same can be said about e-commerce websites as well.

      Machine learning, cognitive computing and artificial intelligence are some terms that most people read about when it comes to advanced analytics. These subjects give a company an edge or an advantage over other businesses in the same industry. Every business leader is now facing an unanticipated and new competitor, and these leaders are looking for ways to develop new strategies that will help them prepare their business for the future. Businesses can always try a variety of strategies, but they all will boil down to one fact – you must always follow the data. This book will help you learn more about how you can use machine learning to delve into the data, and how you can derive some predictions from that data. You will also learn what you should think about when it comes to machine learning, and also see what how you can analyze data using different machine learning algorithms.

      Machine learning is a topic that is discussed in almost every organization in any industry. Most organizations choose to use machine learning algorithms to identify new ways to make use of the data that they collect. So, why should you add machine learning to your processes? If you use the right machine learning algorithms, you can predict how a business or how a customer will act. You can always predict what will happen next. When you constantly add new data to the algorithm or model, the machine will learn from that data and update the solution as often as it can. The value of doing this is evident – if you use the correct data in a machine learning model and constantly update that data, you can predict the future with ease.

      Machine learning is a subset of artificial intelligence, and this method of learning allows any machine to gather information from input data. This means that we will not be using any explicit commands or code to explain to the system about what it will need to do. That being said, it is not easy to implement machine learning models in a business. A machine learning will use different algorithms that learn only from the data, and derive methods that can be used to improve, describe or predict the outcomes. When the machine takes in more data, you can ensure that you train the machine well to produce accurate results.

      Once you train the model, and give it some new data, it should provide you with an output. For instance, if you use a predictive algorithm, you will create a predictive model. When you feed that model with any new data, the machine will give you an output that is based on the training data set that you had initially used. Machine learning is now being used extensively to develop some analytics model.

      You may have interacted with many machine learning applications in the past. For instance, if you visit Amazon or Flipkart and begin to view products, you will be presented with other products that are similar to what you were looking at. These recommendations are not coded into the system, but are suggestions that are given to you through a machine learning model. The model will look at all your history and use that information to present you with similar products.

      There are different types of machine learning algorithms that a business can use depending on the type of information or data it has available. For example, if the business has a labeled data set, it can use any supervised machine learning algorithm to predict the future. On the other hand, if the business did not have a labeled data set, it could use some unsupervised machine learning algorithm to train the model to derive an output. This book covers some of the most commonly used machine learning algorithms.

      Throughout this book, you will gather information on what machine learning is, and how you can build your very own model in Python using SciKit learn. If you want to learn more about machine learning, deep learning and neural networks, and how you can build these models in Python, this book is invaluable. This book covers the use of the NumPy and Pandas libraries in Python and will help you build a machine learning model and a neural network in SciKit-learn using those libraries. You will come across some examples of code that will help you understand the steps you will need to follow when it comes to building a machine learning application or a neural network. It is only when you understand these codes fully that you should start with building your applications.

      I hope this book will help you gather more insights on what machine learning is, and how you can use it to analyze different data sets.

      Chapter One: An Introduction to Machine Learning

      Machine learning is a process through which machines with inbuilt artificial intelligence or AI often learn processes, probability, identifying problems and solutions. Such machines are used for data analysis, recognition, predictions, diagnosis and projections. They learn from training data, a sample database that is identical to the entire population, to identify different patterns within the data and to use those patterns, as well as help find solutions to problems. Out of the various methods of learning mechanisms used to help a machine learn, unsupervised machine learning, reinforcement learning and supervised machine learning are the most common amongst them. The following chapters will cover these concepts.

      In a layman's language, the change in the structure of a machine to enhance its performance is a classic example of how a machine learns.

      Let’s say if a machine must predict which team will win the Barclays Premier League. The programmer will train or feed the machine with historical data about the team’s performance and the player’s performances. Using such information and data the machine can identify a pattern and correlations between the data points or variable in the data set. The machine can then use these patterns and predict which team will win the Barclays Premier League.

      Skeptics often wonder why machines must learn since they are pretty aware of what these machines are capable of. Facebook has used machine learning
