What is similarity based learning?

It is the use of a pairwise relation approach between two or more objects to confer labels on unlabeled ones.

What is supervised machine training ?

It is the type of machine training which uses labelled training data to predict and output. The data acts as a "supervisor", teaching the machines how to correctly predict the output.

Applications of similarity based learning ?

Nearest neighbor approach

It uses proximity to make predictions concerning groupings of individual data points. The number of the yet to be predicted variable is known as "K". KNN functions similarly to the search for individuals with identical features. It locates unknown data points which are similar to the known.

Similarity based approach

It estimates the class label of a test sample, bearing in mind its similarities with labelled train examples. It does not require direct access to sample features. This means the sample space can be of any set, provided the similarity function has been thoroughly defined for any paired samples.

Featured vector-based approach

A feature vector in machine learning is a list of numerical and calculated values. This approach uses numerical features for object description. In other words, the objects have numerical representation which make it easy to analyse statistically.

Biomechanical Ontology

Ontology refers to the purposeful design of an artefact to enable the modelling of knowledge about a real emergent domain. It is a set of concepts within a particular script, which he says are its properties and how they are related. Ontology drives any type of data or variation to a specific task.

In ontological databases, domain specific knowledge is included. Biological characterization makes use of controlled vocabulary, for domain specific descriptions. Phenotype ontology characterises human genetics and organism databases. These phenotypes are observed and annotated under certain specific situations. It is also used to observe biological functions, anatomical locations or chemical substances.

In addition, it makes use of OWL(Web Ontology Language). It makes exclusive use of description logic, which is a first order predicate. This logic defines "Made in OWL" statements, which control domain-specific interpretation.
