A novel data transformation approach for improved cluster performance

K Manohar, K Manohar, P Hosein - 2023 IEEE International …, 2023 - ieeexplore.ieee.org
We compare the performance of a new feature scaling approach against conventional
feature scaling techniques for clustering. Our approach creates a more well-defined cluster …

Performance evaluation and comparison of a new regression algorithm

S Gooljar, K Manohar, P Hosein - arXiv preprint arXiv:2306.09105, 2023 - arxiv.org
In recent years, Machine Learning algorithms, in particular supervised learning techniques,
have been shown to be very effective in solving regression problems. We compare the …

A centroid based vector quantization reversible data hiding technique

K Manohar, TD Kieu - Multimedia Tools and Applications, 2019 - Springer
In this paper, we propose a reversible data hiding scheme that exploits the centroid formula.
Specifically, we use it to define a centroid boundary vector and a centroid state codebook …

Improving Academic Advising by Predicting a Student's GPA given their Chosen Courses

K Manohar, P Hosein - 2023 IEEE International Conference on …, 2023 - ieeexplore.ieee.org
The academic advising process is very beneficial since many students are unaware of the
difficulties they may face when taking certain courses or combinations of courses in the …

A counter-embedding IPVO based reversible data hiding technique

K Manohar, TD Kieu - Multimedia Tools and Applications, 2021 - Springer
Improved pixel value ordering utilizes two embedding procedures. These are the maximum
and minimum embedding procedures. The maximum embedding procedure modifies a pixel …

A Strategy for the Linear Time Implementation of the SMVQ Algorithm

K Manohar, TD Kieu - IETE Technical Review, 2022 - Taylor & Francis
This paper proposes a linear time implementation of the Side Match Vector Quantization (SMVQ)
algorithm. It maps the side match distortion values between codewords and a boundary …

An SMVQ-based reversible data hiding technique exploiting side match distortion

K Manohar, TD Kieu - Multimedia Tools and Applications, 2018 - Springer
Secure online communication is a necessity in today’s digital world. This paper proposes a
novel reversible data hiding technique based on side match vector quantization (SMVQ). The …

A Linear Time Side Match Vector Quantization Implementation

K Manohar, TD Kieu - 2020 7th International Conference on …, 2020 - ieeexplore.ieee.org
Side match vector quantization (SMVQ) is slower than vector quantization (VQ). For each
SMVQ index, it generates a state codebook SCB. The N codewords from the main codebook D …

On the Prediction of Kidney Stone Formers

K Harrykissoon, S Persaud, K Manohar… - 2023 IEEE …, 2023 - ieeexplore.ieee.org
The early detection of kidney stone formers will significantly reduce treatment costs as well
as the discomfort and inconvenience experienced by patients. We collected demographic …

[PDF][PDF] A Successive Quadratic Approximation Approach for Tuning Parameters in a Previously Proposed Regression Algorithm.

P Hosein, K Manohar, K Manohar - DATA, 2023 - scitepress.org
We investigate a previously proposed regression algorithm that provides excellent performance
but requires significant computing resources for parameter optimization. We summarize …
