Supervised machine learning is an approach to building predictive models that leverages labeled training data. It’s different from the other approaches we’ve covered here because rather than trying to build a model from scratch, supervised learning uses existing data sets with labels (or classifications) already attached. For example, you might have thousands of photos labeled by whether they’re of cats or dogs. You could use this dataset as training material for a supervised machine learning algorithm that learns how to classify new images based on what it has learned from your training set.

Supervised Learning is the process by which a system uses data to model how the world works. It can be applied to tasks like classification and regression, or anomaly detection.
Supervised learning is used for tasks like classification, regression, and anomaly detection. While there are many types of supervised learning methods (such as decision trees), this article will focus on one specific technique: Support Vector Machines (SVMs).
The most common task of supervised learning is classification.
Supervised learning involves training a model to predict the value of an output variable based on its input variables. The most common task of supervised learning is classification, which involves determining what type of thing an example belongs to. For example, you might want your model to learn that emails flagged as spam have certain characteristics (such as containing certain words or phrases), so that it can classify other emails and tell you whether they were flagged as spam or not.
Supervised methods aren’t limited just to classification: there are also regression problems where we want our models to predict continuous values instead of discrete ones like true/false answers; clustering tasks where we want them too group similar objects into groups; and recommendation systems where we want recommendations based on past user behavior (for instance: “Users who bought X also bought Y”).
Classification involves determining what type of thing an example belongs to.
Classification is one of the most common forms of supervised learning. It involves dividing examples into categories, based on their features. For example, we could train a classifier to determine whether an email message has been flagged as spam or not.
A classification algorithm such as k-nearest neighbor (KNN) would take this approach: it would assign each new email message to whichever category contains its k nearest neighbors in the training data set (where k is some number between 1 and infinity). In other words, if you were using KNN with two neighbors and received an email from someone who had never sent any emails before, then your algorithm would assume that they were likely sending you junk mail because all their previous messages had been flagged as such by other users who knew them better than yourself!
An example of a classification problem might be determining if an email message has been flagged as spam or not.
In the world of machine learning, classification is the process of determining what type of thing an example belongs to. For example, if you were trying to classify emails as spam or not spam, your training data would consist of previously labeled examples–that is, emails that have already been labeled as either spam or not spam by some human expert. You can think of this as similar to how we use textbooks in school: they’re really just books that have been written by experts and then published so new students can learn from them (i.e., read them).
In supervised learning problems like email spam classification where there are clear rules governing what makes something “spam” vs “not spam”, it’s possible for us humans to train our algorithm using existing training data sets that have already been labeled correctly by humans (i.e., giving each example a label). In contrast with unsupervised learning problems which don’t require such labels because they involve analyzing data without any predetermined categories being present (such as clustering algorithms), these types of problems often require large amounts of high-quality training data before any meaningful results can be produced

Classification is when you want your machine learning model to predict if a patient has cancer or not.
Regression is when you want to predict how much money will be spent on a product based on factors such as age and gender of the customer.
Anomaly detection is when you want your machine learning model to find unusual patterns in data that may indicate fraudulent transactions or other types of frauds/errors in your business processes (e.g., credit card transactions).
Supervised Learning is a key technique in the world of machine learning
Supervised learning is a key technique in the world of machine learning. It’s used to solve classification problems and can also be used to solve regression problems.
Let’s take a look at an example of each type:
- Classification problem: You have a set of data that contains features (e.g., age and gender) and labels (e.g., whether someone has diabetes or not). Your goal is to find patterns in this data which will allow you to predict what label should be assigned for new instances without knowing anything about them beforehand. For example, let’s say we want our model know whether someone has diabetes based on their age, weight and gender–the four columns shown below represent these variables:
There are many other types of supervised learning, but we’ve covered the most common ones here. It’s important to remember that supervised learning is just one technique in the world of machine learning.
