What is a classification?
Classification : It is a Supervised Learning task where output is having defined labels (discrete value). For example in above Figure A, Output – Purchased has defined labels i.e. 0 or 1 ; 1 means the customer will purchase and 0 means that customer won’t purchase. The goal here is to predict discrete values belonging to a particular class and evaluate on the basis of accuracy.#N#It can be either binary or multi class classification. In binary classification, model predicts either 0 or 1 ; yes or no but in case of multi class classification, model predicts more than one class.#N#Example: Gmail classifies mails in more than one classes like social, promotions, updates, forum.

What is unsupervised learning?
Unsupervised Learning – The data collected here has no labels and you are unsure about the outputs. So you model your algorithm such that it can understand patterns from the data and output the required answer. You do not interfere when the algorithm learns.
What is the principle of supervising learning?
Else, the teacher tunes the student and makes the student learn from the mistakes that he or she had made in the past. That is the basic principle of Supervised Learning.
What is regression learning?
Regression is the kind of Supervised Learning that learns from the Labelled Datasets and is then able to predict a continuous-valued output for the new data given to the algorithm. It is used whenever the output required is a number such as money or height etc. Some popular Supervised Learning algorithms are discussed below:
What is reinforcement learning?
Reinforcement Learning – There is no data in this kind of learning, nor do you teach the algorithm anything. You model the algorithm such that it interacts with the environment and if the algorithm does a good job, you reward it, else you punish the algorithm.

There are 3 types of Machine Learning which are based on the way the algorithms are created. They are:
What is machine learning?
Machine Learning, in the simplest of terms, is teaching your machine about something. You collect data, clean the data, create algorithms, teach the algorithm essential patterns from the data and then expect the algorithm to give you a helpful answer. If the algorithm lives up to your expectations, you have successfully taught your algorithm.
What is a naive Bayes classifier?
Naive Bayes Classifier – Naive Bayes algorithms assume that the features of the dataset are all independent of each other. They work great on large datasets. Directed Acyclic Graphs (DAG) is used for the purpose of classification.
What is supervised learning classification?
This technique is used when the input data can be segregated into categories or can be tagged. If we have an algorithm that is supposed to label ‘male’ or ‘female,’ ‘cats’ or ‘dogs,’ etc., we can use the classification technique. Here, finite sets are distinguished into discrete labels.
When do we use Supervised Learning?
Hence, this technique is used if we have enough known data (labeled data) for the outcome we are trying to predict. In supervised learning, an algorithm is designed to map the function from the input to the output.
What is machine learning?

Some of the common applications built around this technique are recommendations, speech recognition, medical imaging, etc.
Why do classifiers need training?
That is, classifiers can be given proper training to help distinguish themselves from other class definitions and define perfect decision boundaries. We get a clear picture of every class defined. The decision boundary can be set as the mathematical formula for classifying future inputs.
Can a machine learn from training data?
As this learning method cannot handle huge amounts of data, the machine has to learn itself from the training data.
What is supervised learning?
Supervised learning, also known as supervised machine learning, is a subcategory of machine learning and artificial intelligence. It is defined by its use of labeled datasets to train algorithms that to classify data or predict outcomes accurately. As input data is fed into the model, it adjusts its weights until the model has been fitted appropriately, which occurs as part of the cross validation process. Supervised learning helps organizations solve for a variety of real-world problems at scale, such as classifying spam in a separate folder from your inbox.
Why is supervised learning important?
Supervised learning models can be a valuable solution for eliminating manual classification work and for making future predictions based on labeled data. However, formatting your machine learning algorithms requires human knowledge and expertise to avoid overfitting data models.
What are the two types of data mining?
Supervised learning can be separated into two types of problems when data mining—classification and regression: 1 Classification uses an algorithm to accurately assign test data into specific categories. It recognizes specific entities within the dataset and attempts to draw some conclusions on how those entities should be labeled or defined. Common classification algorithms are linear classifiers, support vector machines (SVM), decision trees, k-nearest neighbor, and random forest, which are described in more detail below. 2 Regression is used to understand the relationship between dependent and independent variables. It is commonly used to make projections, such as for sales revenue for a given business. Linear regression, logistical regression, and polynomial regression are popular regression algorithms.
What is a naive Bayes classifier?
Naive Bayes is classification approach that adopts the principle of class conditional independence from the Bayes Theorem. This means that the presence of one feature does not impact the presence of another in the probability of a given outcome, and each predictor has an equal effect on that result. There are three types of Naïve Bayes classifiers: Multinomial Naïve Bayes, Bernoulli Naïve Bayes, and Gaussian Naïve Bayes. This technique is primarily used in text classification, spam identification, and recommendation systems.
Is supervised learning time intensive?
Training supervised learning models can be very time intensive. Datasets can have a higher likelihood of human error, resulting in algorithms learning incorrectly. Unlike unsupervised learning models, supervised learning cannot cluster or classify data on its own.
What is supervised machine learning?
Supervised Machine Learning is defined as the subfield of machine learning techniques in which we used labelled dataset for training the model, making prediction of the output values and comparing its output with the intended, correct output and then compute the errors to modify the model accordingly. Also as the system is trained enough using this learning method it becomes capable enough to provide the target values from any new input.
What is the objective of SVM?
The objective of SVM is to get the hyperplane in a way that all the independent variables of one class should be on one side. An optimal SVM function will result in a hyperplane that is at an equal distance from both the class.
What is output class in classification?
In classification, the output variable is discrete. i.e. we train the hypothesis (f (x)) in a way to get discrete output (y) for the input data (x). The output can also be termed as a class. For example, by taking the above example of house price, we can use classification to predict whether the house price will be above or below instead of getting the exact value. So we have two classes, one if the price is above and the other if it is below.
What is semi-supervised learning?
The semi-supervised learning approach takes both labeled and unlabeled training data input. This type of learning is useful when it is difficult to extract useful features from unlabeled data (supervised approach) and data experts find it difficult to label the input data (unsupervised approach).
What is supervised ML?
In the supervised ML algorithm, the output is already known. There is a mapping of input with the output. Hence, to create a model, the machine is fed with lots of training input data (having input and corresponding output known).

What is machine learning?
Machine Learning is a field of science that deals with computer programs learning through experience and predicting the output. The main feature of ML is learning from experience. The learning happens when the system fed with training input data makes changes in its parameters and adjusts itself to give the desired output.
Is unsupervised learning more accurate than unsupervised learning?
It is more accurate than unsupervised learning as input data and corresponding output is well known, and the machine only needs to give predictions.
