k-Nearest Neighbour Classifiers
Perhaps the most straightforward classifier in the arsenal or machine learning techniques is the Nearest Neighbour Classifier – classification is achieved by identifying the nearest neighbours to a query example and using those neighbours to determine the class of the query. This approach to classification is of particular importance today because issues of poor run-time performance is not such...
متن کاملIntroduction to k Nearest Neighbour Classification and Condensed Nearest Neighbour Data Reduction
Suppose a bank has a database of people’s details and their credit rating. These details would probably be the person’s financial characteristics such as how much they earn, whether they own or rent a house, and so on, and would be used to calculate the person’s credit rating. However, the process for calculating the credit rating from the person’s details is quite expensive, so the bank would ...
متن کاملAn empirical analysis of the probabilistic K-nearest neighbour classifier
The probabilistic nearest neighbour (PNN) method for pattern recognition was introduced to overcome a number of perceived shortcomings of the nearest neighbour (NN) classifiers namely the lack of any probabilistic semantics when making predictions of class membership. In addition the NN method possesses no inherent principled framework for inferring the number of neighbours, K, nor indeed assoc...

متن کاملExtending the K-Nearest Neighbour Classification Algorithm to Symbolic Objects
Riassunto: L’analisi di dati simbolici generalizza alcuni metodi statistici standard al caso di oggetti simbolici (SO). Questi oggetti, informalmente definiti “dati aggregati”, poiché sintetizzano le informazioni relative ad un gruppo di individui, possono essere confrontati al fine di individuare dei cluster, di classificarli o ordinarli in base al loro grado di generalizzazione. L’articolo pr...
