Self-supervised learning (SSL) has been widely applied in the pretraining phase of models. Among these SSL methods, the various data augmentation used in contrastive learning for constructing positive and negative sample pairs conveniently contribute to alleviating the issue of data scarcity in few-shot learning (FSL) tasks. Therefore, many approaches have introduced contrastive learning into FSL tasks. However, most of these methods only utilize the global embedding information of the entire image, making it challenging to capture and fully leverage the local visual information and structural details of image samples. To address this, we proposes a novel Spatial Reconstruction Contrastive Pretext Task (SRCPT) to enhance the FSL training objective. By constructing a two-branch network, the model can use local patches of the image for feature map reconstruction and employ spatial reconstruction weights to create a contrastive learning objective. The enhanced FSL objective of SRCPT encourages the model to capture more transferable spatial structures and local feature information, enabling the model to adapt well to new categories even with a few samples. Extensive experiments demonstrate that our proposed SRCPT method achieves state-of-the-art performance in three popular benchmark datasets across three types of few-shot image classification tasks.

In this paper, we develop a method to monitor the emotional state of students and teachers during the study process based on facial expressions using machinelearning and deep learning techniques. We describe the implementation of the created emotion detection model into the learning process as a web application to determine the emotional state of students and teachers in a digital learning environment in near real-time. Several training methods and models were examined using Python and Keras Tensorflow library and the results were compared against the classifiers SupportVector machine, Random Forest, and Convolutional Neural Networks (CNN). The average recognition rate of the best model is about 96% and the proposed system is able to recognize emotions in near real-time.

Esophageal cancer (EC) is a significant health concern worldwide, and predicting its metastatic progression is essential for planning effective treatments. Histopathological intervention is the gold standard for diagnosing Esophageal Cancer Metastasis (ECM). However, we introduced a noninvasive, data-driven approach utilizing different machinelearning (ML) algorithms on clinical data from TCGA to predict the risk of ECM. Among these algorithms, CatBoost stands out, achieving a 73% accuracy and a 75% area under the curve (AUC) using 5-fold cross-validation with a standard deviation of 4% among 5-folds. We visualized feature importance graphs and feature correlations to explain the decision-making of ML models. Our findings highlight associations between height, weight, age, alcohol consumption, the number of packs smoked, tumor location, and the risk of metastasis in EC patients. This approach offers a promising way to enhance EC metastasis prediction while minimizing invasive procedures.
