IMPLEMENTATION OF GAIN RATIO AND K-NEAREST NEIGHBOR FOR CLASSIFICATION OF STUDENT PERFORMANCE

open access: yesPilar Nusa Mandiri, 2020
Predicting student performance is very useful in analyzing weak students and providing support to students who face difficulties. However, the work done by educators has not been effective enough in identifying factors that affect student performance ...

Approximate $k$-Nearest Neighbor Graph on Moving Points [PDF]

open access: yesTransactions on Combinatorics, 2023
In this paper, we introduce an approximation for the $k$-nearest neighbor graph ($k$-NNG) on a point set $P$ in $\mathbb{R}^d$. For any given $\varepsilon>0$, we construct a graph, that we call the \emph{approximate $k$-NNG}, where the edge with the $i ...

k-Nearest Neighbor Learning with Graph Neural Networks

open access: yesMathematics, 2021
k-nearest neighbor (kNN) is a widely used learning algorithm for supervised learning tasks. In practice, the main challenge when using kNN is its high sensitivity to its hyperparameter setting, including the number of nearest neighbors k, the distance ...

A generalized fuzzy k-nearest neighbor regression model based on Minkowski distance

open access: yesGranular Computing, 2021
The fuzzy k-nearest neighbor (FKNN) algorithm, one of the most well-known and effective supervised learning techniques, has often been used in data classification problems but rarely in regression settings. This paper introduces a new, more general fuzzy

A new locally adaptive K-nearest centroid neighbor classification based on the average distance

open access: yesConnection Science, 2022
The classification performance of a k-nearest neighbour (KNN) method is dependent on the choice of the k neighbours of a query. However, it is difficult to optimise the performance of KNN by choosing appropriate neighbours and an appropriate value of k ...

Sparse Coefficient-Based ${k}$ -Nearest Neighbor Classification

open access: yesIEEE Access, 2017
K-nearest neighbor rule (KNN) and sparse representation (SR) are widely used algorithms in pattern classification. In this paper, we propose two new nearest neighbor classification methods, in which the novel weighted voting methods are developed for ...
