a. Supervised Learning:
One of the most common forms of machine learning, supervised learning, aims to train the different algorithms to describe input data. It allows the algorithms to present the input data in such a manner that it can produce outputs effectively and without making many errors.
The learning problems in Supervised learning include problems like classification and regression. The different classified outputs used in these problems account for different categories, putting numerical value for the problems.
You can notice the different applications of supervised learning around recognizing speech, faces, objects, handwriting, or gestures.
b. Unsupervised Learning
Unlike supervised learning, where the platform uses labeled data to train the applications, unsupervised learning uses unlabeled data for its training. More of a trial and error method, the unsupervised learning method is a reliable means to showcase different unknown data features and patterns, allowing categorization. Broadly categorized as association problems and clustering, this form of learning allows AI to ask questions the right way.
By framing the right question to be asked, this platform allows the program to model several data organizations to highlight anomalies. Further, the association over this type of learning could be applied to know more about tendencies based on newly discovered relationships among variables over a vast database.
c. Semi-supervised Learning (SSL)
Semi-supervised learning falls in between unsupervised and supervised learning. This method of learning is used by AI when it requires solving balance around different approaches. In several cases using this learning method, the reference data needed to find a solution is available, but it is somewhere either accurate or incomplete. This is where SSL comes to play as it can easily access reference data and imply the use of unsupervised learning techniques to find the nearest possible solution.
Interestingly, SSL uses both labeled & unlabelled data. This way, AI can easily implement the function of both the data set to be able to find relationships, patterns, and structures. It is also used in reducing human biases in the process.
d. Reinforcement Learning
A form of the dynamic learning process, Reinforcement learning allows the systems to train algorithms with the use of punishment and reward systems. The reinforcement learning algorithm finds solutions by interacting with the individual components of the environment. The language uses rewards by executing operations correctly and penalties in a situation where it cannot execute operations nicely.
This way, the algorithm learns without being taught by any human and uses the least menial intervention in learning. Usually consisting of three components: agent, environment, and actions. This learning process focuses on maximizing the reward and diminishing the penalty to learn well.
