Currently,the improvement in AI is mainly related to deep learning techniques that are employed for the classification,identification,and quantification of patterns in clinical images.The deep learning models show more remarkable performance than the traditional methods for medical image processing tasks,such as skin cancer,colorectal cancer,brain tumour,cardiac disease,Breast cancer(BrC),and a few more.The manual diagnosis of medical issues always requires an expert and is also expensive.Therefore,developing some computer diagnosis techniques based on deep learning is essential.Breast cancer is the most frequently diagnosed cancer in females with a rapidly growing percentage.It is estimated that patients with BrC will rise to 70%in the next 20 years.If diagnosed at a later stage,the survival rate of patients with BrC is shallow.Hence,early detection is essential,increasing the survival rate to 50%.A new framework for BrC classification is presented that utilises deep learning and feature optimization.The significant steps of the presented framework include(i)hybrid contrast enhancement of acquired images,(ii)data augmentation to facilitate better learning of the Convolutional Neural Network(CNN)model,(iii)a pre‐trained ResNet‐101 model is utilised and modified according to selected dataset classes,(iv)deep transfer learning based model training for feature extraction,(v)the fusion of features using the proposed highly corrected function‐controlled canonical correlation analysis approach,and(vi)optimal feature selection using the modified Satin Bowerbird Optimization controlled Newton Raphson algorithm that finally classified using 10 machine learning classifiers.The experiments of the proposed framework have been carried out using the most critical and publicly available dataset,such as CBISDDSM,and obtained the best accuracy of 94.5%along with improved computation time.The comparison depicts that the presented method surpasses the current state‐ofthe‐art approaches. 展开更多

The main objective of this work was the construction of a Multidisciplinary Learning Object as a tool for teaching, enabling the use of information and communication technologies for use by teachers acting in elementary school, based on Discourse Analysis, Theory Cybernetic-systemic, the Multiple Intelligences and Collaborative Learning. All of them are informed by Foucault, Pecheux, Bakhtin, Gardner, Levy, and others. The theoretical contribution is justified to the extent that the student is above all a being inserted into a user company tool created by it over time, to act on the world. Theoretical principles underlying the construction of learning objects as tools for teaching are related to teaching and learning. The developed learning object establishes the link between the fields of pedagogy and usability, the step by step construction of each of them and their purposes, characteristics, and all detailed in the development of research. The construction of the learning object follows the steps of a methodological construction for the development of a computerized product, followed by a systematic planning and the design and construction. 展开更多

However, problems of varieties have also occurred along its way. People never stop thinking of better strategies either in designing online course wares or tutorials to help smooth the learning process. My experience as a tutor is that interaction of affective domain and higher levels of cognitive domain of Bloom's Taxonomy plays an important role in face-to-face tutorials of online English learning. 展开更多

Basic foreign language teaching for language majors plays a significant role in the process of foreign language teaching and is also a crucial stage in the training of foreign language talents. During the stage teachers should learn about students' learning motives and the beginners' psychological state to rouse students' interest and mobilize their initiatives so that students can change from passive learning to active learning. The teaching effects will thereby be substantially enhanced. 展开更多

The purpose of this project is to reach more students in food, agricultural, and environmental sciences with a globalized undergraduate curriculum, by providing contextually-rich reusable learning objects (RLOs) and authentic case studies that address multidisciplinary issues. Reusable learning objects (RLOs) are self--contained, digital learning activities that range in length from 2 to 15 minutes. RLOs can contain a wide array of media, including text, web sites, charts, maps, models, PowerPoint presentations, photos, case studies, simulations, video clips, audio clips, and assessments, Food and agricultural sciences faculty at the University of Florida, the University of Georgia, and Texas A&M University have been selected to be part of a Faculty Learning Community that Will work together in curriculum and RLO development, and will participate in an international study experience funded by this project. For each experience, a group of approximately ten faculty and three project team members will spend roughly two weeks in a Latin American/Caribbean basin country. Various social science data collection processes and evaluation strategies will be the focus of the presentation. The use of preflective and reflective instruments to measure initial attitudes or beliefs about the context-rich multidisciplinary experience and expected gains from participating in the curricula development will be demonstrated. 展开更多

With intensive training, human can achieve impressive behavioral improvement on various perceptual tasks. This phenomenon, termed perceptual learning, has long been considered as a hallmark of the plasticity of sensory neural system. Not surprisingly, high-level vision, such as object perception, can also be improved by perceptual learning. Here we review recent psychophysical, electrophysiological, and neuroimaging studies investigating the effects of training on object selective cortex, such as monkey inferior temporal cortex and human lateral occipital area. Evidences show that learning leads to an increase in object selectivity at the single neuron level and/or the neuronal population level. These findings indicate that high-level visual cortex in humans is highly plastic and visual experience can strongly shape neural functions of these areas. At the end of the review, we discuss several important future directions in this area. 展开更多
