A Cloud-based Machine Learning Pipeline for the Efficient Extraction of Insights from Customer Reviews
Robert Lakatos, Gergo Bogacsovics, Balazs Harangi +5
The efficiency of natural language processing has improved dramatically with the advent of machine learning models, particularly neural network-based solutions. However, some tasks…
A stochastic approach to handle knapsack problems in the creation of ensembles
Andras Hajdu, Gyorgy Terdik, Attila Tiba +1
Ensemble-based methods are highly popular approaches that increase the accuracy of a decision by aggregating the opinions of individual voters. The common point is to maximize accu…
Efficient Learning of Model Weights via Changing Features During Training
Marcell Beregi-Kovács, Ágnes Baran, András Hajdu
In this paper, we propose a machine learning model, which dynamically changes the features during training. Our main motivation is to update the model in a small content during the…
Optimizing Majority Voting Based Systems Under a Resource Constraint for Multiclass Problems
Attila Tiba, Andras Hajdu, Gyorgy Terdik +1
Ensemble-based approaches are very effective in various fields in raising the accuracy of its individual members, when some voting rule is applied for aggregating the individual de…
High Performance Computing in Medical Image Analysis HuSSaR
Laszlo Kovacs, Roland Kovacs, Andras Hajdu
In our former works we have made serious efforts to improve the performance of medical image analysis methods with using ensemble-based systems. In this paper, we present a novel h…
Finding well approximating lattices for a finite set of points
A. Hajdu, L. Hajdu, R. Tijdeman
In this paper we address the problem of finding well approximating lattices for a given finite set of points in . More precisely, we search for $ǒ,\v{d_1}, \dots…
A Two-phase Decision Support Framework for the Automatic Screening of Digital Fundus Images
Balint Antal, Andras Hajdu, Zsuzsanna Maros-Szabo +3
In this paper we give a brief review on the present status of automated detection systems describe for the screening of diabetic retinopathy. We further detail an enhanced detectio…
An Ensemble-based System for Microaneurysm Detection and Diabetic Retinopathy Grading
Balint Antal, Andras Hajdu
Reliable microaneurysm detection in digital fundus images is still an open issue in medical image processing. We propose an ensemble-based framework to improve microaneurysm detect…
An ensemble-based system for automatic screening of diabetic retinopathy
Balint Antal, Andras Hajdu
In this paper, an ensemble-based method for the screening of diabetic retinopathy (DR) is proposed. This approach is based on features extracted from the output of several retinal…
An Unsupervised Ensemble-based Markov Random Field Approach to Microscope Cell Image Segmentation
Balint Antal, Bence Remenyik, Andras Hajdu
In this paper, we propose an approach to the unsupervised segmentation of images using Markov Random Field. The proposed approach is based on the idea of Bit Plane Slicing. We use…
Approximations of the Euclidean distance by chamfer distances
Andras Hajdu, Lajos Hajdu, Robert Tijdeman
Chamfer distances play an important role in the theory of distance transforms. Though the determination of the exact Euclidean distance transform is also a well investigated area,…
