Multiclass classificationdeep learningconvolutional neural networkdata imbalancedata overlappingdata sparsenessIn educational data mining, student classification is an important and popular task by predicting final study status of each student. In the existing works, this task has been considered in many ...
In this study, we propose a sequential model for medical multiclass image classification, as depicted in Figure 1. Our approach begins by focusing on dataset quality and benchmarking, adhering to state-of-the-art (SOTA) guidelines. We carefully select seven outstanding datasets to ensure robustnes...

The activation function is softmax because it is a multiclass image classification problem. Compiling the CNN model We compile the network using categorical loss and accuracy because it involves multiples classes. model.compile(optimizer='adam', loss=keras.losses.CategoricalCrossentropy(), metrics=[...
This paper proposes a deep learning framework for multi-class fruits detection based on improved Faster R-CNN. The proposed framework includes fruits image library creation, data argumentation, improved Faster RCNN model generation, and performance evaluation. This work is a pioneer to create a ...
Finally CNNs are a great approach for text classification. However a lot of data is needed for training a good model. It would be interesting to compare this results with a typical machine learning approach. I expect that using ML for all datasets except Yelp getting similar results. If you...

The intuition behind transfer learning for image classification is that if a model is trained on a large and general enough dataset, this model will effectively serve as a generic model of the visual world. You can then take advantage of these learned feature maps without having to start from...
