How does machine learning work?

Machine learning is the best tool available today to analyze, understand and find data models. One of the key concepts of machine learning is that computers can be trained automatically, which can be done purely or is impossible for humans. There are still obvious shortcomings of the previous analysis that machine learning can only be decided by human intervention.

Machine Learning uses data to transmit it to an algorithm.

Machine learning process: Suppose you want to create a program that recognizes objects. To train this model, you must use a classifier. The classifier uses the function of an object to try to find this type of object. In the example, the classifier will be trained to detect if the image is:

  • Bike
  • Ship
  • Car

These 3 objects are different types of objects. The classifier must remember. To create a classifier, you must have a certain amount of input data and specify exactly the type of data of each type. This algorithm will take the data into a model and then classify it into different types. This form of action is called supervised learning. With supervised learning, training data will be transmitted to your algorithm and marked with the results.

How does machine learning work? Machine learning is the place where all learning takes place. Machine learning is like humans. Humans learn from experience. The more we know, the easier it will be to predict what will happen next. In comparison, when we experience an event that has never been seen before, the probability of success is less than previous experience. The machine can be driven in the same way. To increase the accuracy of the prediction, the machine can see the example that we must verify.

The main objective of machine learning is learning and inference. The first thing is that the machine repeatedly learns by discovering patterns or patterns. The discovery is due to the existence of data. An important goal of a data scientist is the rigorous selection of data that supports the device. The properties used to solve a problem are called feature vectors. You can think of an entity vector as a subset of all the data used to solve a problem.

For example, for a machine that understands the relationship between wages and the ability to eat in a strange restaurant, the result is that the machine seeks a positive relationship between wages and meals in a fancy restaurant.

When the model is created, it is likely to be tested, its performance with data never seen before. Strange data is transformed into a characteristic vector and collected into a model and can be predicted. It is a good part of machine learning. It is not necessary to add rules or continue training within the model. You can use the previous model train to infer more new information.

Machine learning can be divided into 2 main types of learning: supervised learning and non-pedagogical learning (unsupervised learning), which has many other algorithms.

Supervised teaching

The algorithm, section data for the train (training data) and the return of humans are required to know the relationship between the data entered. In the data, for example, marketing expenses and weather forecasts are used as input to predict how many cans can be sold.

You can use supervised learning when the results of the data are already known. This algorithm can predict new data.

There are 2 types of supervised learning like classification and regression.
