The learning that is being done is always based on some sort of observations or data, such as examples, direct experience, or instruction. For instance, you might wish to predict how much a user Bob will like a movie that he hasn't seen, based on her ratings of movies that he has seen. This means making informed guesses about some unobserved property of some object, based on observed properties of that object. Supervised learning is a type of machine learning algorithm that uses a known dataset (called the training dataset) to make predictions. The training dataset includes input data and response values.
If you are not aware of the concepts of decision tree classifier, Please spend some time on the below articles, As you need to know how the Decision tree classifier works before you learning the working nature of the random forest algorithm. Given the training dataset with targets and features, the decision tree algorithm will come up with some set of rules. In decision tree algorithm calculating these nodes and forming the rules will happen using the information gain and gini index calculations. In random forest algorithm, Instead of using information gain or gini index for calculating the root node, the process of finding the root node and splitting the feature nodes will happen randomly.
You are going to learn the most popular classification algorithm. Which is the Random forest algorithm. As a motivation to go further I am going to give you one of the best advantages of random forest. The Same algorithm both for classification and regression, You mind be thinking I am kidding. But the truth is, Yes we can use the same random forest algorithm both for classification and regression.
Artificial intelligence (AI) is the science of programming computers to perceive their environment and make rational, cognitive decisions in order to achieve a goal. It is one of the most rapidly progressing and sought after technologies in the world. It is, however, a rather general term. When most people talk about artificial intelligence, they are usually talking about machine learning. At its most basic definition, machine learning is a method of teaching computers to make predictions based on data.
Today, the machine learning algorithms are extensively used to find the solutions to various challenges arising in manufacturing self-driving cars. With the incorporation of sensor data processing in an ECU (Electronic Control Unit) in a car, it is essential to enhance the utilization of machine learning to accomplish new tasks. The potential applications include evaluation of driver condition or driving scenario classification through data fusion from different external and internal sensors – like lidar, radars, cameras or the IoT (Internet of Things). The applications that run the infotainment system of a car can receive the information from sensor data fusion systems and for example, have the capability to direct the car to a hospital if it notices that something is not right with the driver. This application based on machine learning also includes the driver's speech and gesture recognition and language translation.
