Difference between Supervised and Unsupervised Learning (Machine Learning) is explained here in detail.Â
Supervised learning is the machine learning task of learning a function that maps an input to an output based on example input-output pairs.A wide range of supervised learning algorithms are available, each with its strengths and weaknesses.Â
Unsupervised learning is a type of machine learning that looks for previously undetected patterns in a data set with no pre-existing labels and with a minimum of human supervision.

Major differences between Supervised and Unsupervised Learning
| Supervised Learning | Unsupervised Learning |
| Supervised Learning can be used for 2 different types of problems i.e. regression and classification | Unsupervised Learning can be used for 2 different types of problems i.e. clustering and association. |
| Input Data is provided to the model along with the output in the Supervised Learning. | Only input data is provided in Unsupervised Learning. |
| Output is predicted by the Supervised Learning. | Hidden patterns in the data can be found using the unsupervised learning model. |
| Labeled data is used to train supervised learning algorithms. | Unlabeled data is used to train unsupervised learning algorithms. |
| Accurate results are produced using a supervised learning model. | The accuracy of results produced are less in unsupervised learning models. |
| Training the model to predict output when a new data is provided is the objective of Supervised Learning. | Finding useful insights, hidden patterns from the unknown dataset is the objective of the unsupervised learning. |
| Supervised Learning includes various algorithms such as Bayesian Logic, Decision Tree, Logistic Regression, Linear Regression, Multi-class Classification, Support Vector Machine etc. | Unsupervised Learning includes various algorithms like KNN, Apriori Algorithm, and Clustering. |
| To assess whether right output is being predicted, direct feedback is accepted by the Supervised Learning Model. | No feedback will be taken by the unsupervised learning model. |
| In Supervised Learning, for right prediction of output, the model has to be trained for each data, hence Supervised Learning does not have close resemblance to Artificial Intelligence. | Unsupervised Learning has more resemblance to Artificial Intelligence, as it keeps learning new things with more experience. |
| Number of classes are known in Supervised Learning. | Number of classes are not known in Unsupervised Learning |
| In scenarios where one is aware of output and input data, supervised learning can be used. | In the scenarios where one is not aware of output data, but is only aware of the input data then Unsupervised Learning could be used. |
| Computational Complexity is very complex in Supervised Learning compared to Unsupervised Learning | There is less computational complexity in Unsupervised Learning when compared to Supervised Learning. |
| Supervised Learning will use off-line analysis | Unsupervised Learning uses Real time analysis of data. |
| Some of the applications of Supervised Learning are Spam detection, handwriting detection, pattern recognition, speech recognition etc. | Some of the applications of Unsupervised Learning are detecting fraudulent transactions, data preprocessing etc. |
