ESA☆: A generic framework for semi-supervised inductive learning

چکیده
Semi-supervised learning is crucial in many applications where accessing class labels unaffordable or costly. The most promising approaches are graph-based but they transductive and do not provide a generalized model working on inductive scenarios. To address this problem, we propose generic framework, ESA☆, for semi-supervised based three components: an ensemble of autoencoders providing new data representation that leverages the knowledge supplied by reduced amount available labels; step helps augmenting training set with pseudo-labeled instances and, finally, classifier trained labeled instances. Additionally, also introduce two variants our framework adopting different pseudo-labeling strategies: first, ESALP, confidence-aware label propagation algorithm, while second, ESAGAT, graph convolutional attention network. experimental results show outperforms state-of-the-art methods.

A multiple kernel framework for inductive semi-supervised SVM learning
We investigate the benefit of combining both cluster assumption and manifold assumption underlying most of the semi-supervised algorithms using the flexibility and the efficiency of multiple kernel learning. The multiple kernel version of Transductive SVM (a cluster assumption based approach) is proposed and it is solved based on DC (Difference of Convex functions) programming. Promising result...

متن کاملA novel semi-supervised learning framework for hyperspectral image classification
In this paper, we propose a novel semi-supervised learning classification framework using box-based smooth ordering and Multiple 1D-embedding-based interpolation method in Ref. 25 for hyperspectral images. Due to the lack of labeled samples, conventional supervised approaches cannot generally perform efficient enough. On the other hand, obtaining labeled samples for hyperspectral image classifi...
