Over the last decade, there has been a considerable increase in popularity of online education. As result, learning or e-learning industry flourished, providing benefits to students, learners, educators, and education experts. Despite advantages e-learning, it also its drawbacks. While enables students access materials at their convenience from any location, one significant challenges is lack monitoring level attention during sessions. It challenging ascertain whether student actively engaged process. To address this issue, we have proposed decision support system (DSS) based on wearable physiological sensor signals (i.e., Electroencephalogram (EEG) signals) that can inform instructor attentive. For developing DSS, recorded an EEG-based dataset using neurosky device, 100 individuals participated study. The state divided into two categories: attentive inattentive. In paper, machine techniques are employed integrate which predict, analyze, validate student's inattention throughout session. findings show Support Vector Machine (SVM) approach most efficient method for prediction, achieving accuracy 91.68% compared logistic regression ridge regression. Additionally, examined frequency bands were predicting state, with beta alpha waves being identified as key contributors attention. further evaluate data, use K-means Hierarchical algorithms cluster data points. effectively identifies ideal representative inattentive state. Thus, EEG reveal real-time sessions, promising valuable tool E-Learning Environment.

Abstract Subsistence farmers and global food security depend on sufficient production, which aligns with the UN's “Zero Hunger,” “Climate Action,” “Responsible Consumption Production” sustainable development goals. In addition to already available methods for early disease detection classification facing overfitting fine feature extraction complexities during training process, how signs of green attacks can be identified or classified remains uncertain. Most pests symptoms are seen in plant leaves fruits, yet their diagnosis by experts laboratory is expensive, tedious, labor-intensive, time-consuming. Notably, diseases appropriately detected timely prevented a hotspot paradigm smart, agriculture unknown. recent years, deep transfer learning has demonstrated tremendous advances recognition accuracy object image systems since these frameworks utilize previously acquired knowledge solve similar problems more effectively quickly. Therefore, this research, we introduce two (PDDNet) models fusion (AE) lead voting ensemble (LVE) integrated nine pre-trained convolutional neural networks (CNNs) fine-tuned efficient identification classification.
