Item Deep transfer learning optimization techniques for medical image classification: a review.(2022) Kariuki, Paul Wahome; Gikunda,Patrick Kinyua; Wandeto, John mwangiMedical image classification is a complex and challenging task due to the heterogeneous nature of medical data. Deep transfer learning has emerged as a promising technique for medical image classification, allowing the leveraging of knowledge from pre-trained models learned from large-scale datasets, resulting in improved performance with minimal training and overcoming the disadvantage of small data sets. This paper concisely overviews cutting-edge deep transfer learning optimization approaches for medical image classification. The study covers convolutional neural networks and transfer learning techniques, including relation-based, feature-based, parameter-based, and instance-based transfer learning. Classical classifiers such as Resnet, VGG, Alexnet, Googlenet, and Inception are examined, and their performance on medical image classification tasks is compared. The paper also discusses optimization techniques, such as batch normalization, regularization, and weight initialization, as well as data augmentation and kernel mathematical formulations. The study concludes by identifying challenges when using deep transfer learning for medical image classification and proposing potential future approaches for this field.Item THE CHIEF MAU MAU IDEOLOGUE: GAKAARA WA WANJAU’S CONTRIBUTION TO POLITICAL CONSCIOUSNESS OF THE AGIKUYU, 1940 – 2001(Karatina University, 2022) WAIRIMU, WAITHANWA LUCYItem GROWTH PERFORMANCE OF RABBITFISH (Siganus sutor) REARED IN INTERTIDAL BRACKISH WATER EARTHEN PONDS USING HAPA NETS(Karatina University, 2022) Okemwa, M.

O.Item “The Quest for Quality in University Education in the Post COVID-19 Era: Do Anti-plagiarism Tools Still Matter?” (2022-06) Kavulya, Joseph M.; Kiilu, Vincent Bob; Kyengo, Bernadetta N.Plagiarism is a major global challenge to quality assurance in higher education. Various efforts have been made to overcome the menace including the use of anti-plagiarism tools. At the same time, many questions have been raised about the efficacy of the current generation of tools in detecting, preventing plagiarism, and guaranteeing the quality of education. This paper examines the limitations of plagiarism detection tools in enhancing quality in academic outcomes and proposes measures for improvement. The paper argues that while anti-plagiarism software has a role in preventing plagiarism in academic writing and academic integrity, they are not the panacea to the plagiarism pandemic, especially in the COVID-19 era. It proposes that there is a need to reform methods of assessment and implement forward-looking policies to address the underlying causes of plagiarism, provide students with appropriate information literacy skills training, and above all cultivate a culture of academic integrity in higher education institutions (HEIs).Item OER & Creative Commons Licenses(Karatina University, 2022-10) Murumba, Joan WakasaItem Climate Justice – Environmental issues(Karatina University, 2022-10) Mwangi, James KinyanjuiItem Citation and Referencing(Karatina University, 2022-10) Wamahiga, GeorgeItem Open Access Publishing(Karatina University, 2022-10) Anduvare, Everlyn M'mboneItem Research Publishing and Visibility(Karatina University, 2022-10-25) Otuoma, PeterItem Institutional Repositories: An Introduction(Karatina University, 2022-10-26) Kiilu, Vincent BobItem INFLUENCE OF FOOD DISTRIBUTION SYSTEMS AND MARKET ACCESSIBILTY ON FOOD SECURITY IN SEMI-ARID THARAKA SUB COUNTY, KENYA(Karatina University, 2022-12) KIBETU, DICKSON KINOTIItem Influence of internal quality assurance practices on students’ academic performance in public secondary schools in Kieni East and Kieni West Sub counties, Nyeri County, Kenya(Karatina University, 2022-12) Kagochi, Ednah NjeriItem AT THE PERIPHERY IN MAU MAU DISCOURSE: A CASE OF THE MBEERE OF EMBU COUNTY, KENYA, 1952-2014(Karatina University, 2022-12) Waiganjo, BensonItem Influence of Work Environment Factors on Transfer of Training for Public Secondary School Principals in Nyeri County, Kenya(Karatina University, 2022-12) Mburu, Frasiah WangariItem Research impact: ORCID and Google Scholar Profiles(Karatina University, 2023-03-24) Agava, Stanislaus LitsaliaItem Citation and Referencing(Karatina University, 2023-03-24) Murumba, Joan WakasaItem Publishing: Identifying Credible Journals(Karatina University, 2023-03-24) Anduvare, Everlyn M.Item On and off-campus Access to Karatina University E-resources(Karatina University, 2023-03-24) Kiilu, Vincent BobItem Plagiarism Check(Karatina University, 2023-03-24) Wamahiga, George M.Item Thesis Formatting Guidelines(Karatina University, 2023-03-24) Wamahiga, George M.
