deep learning review paper

In general, a CNN is formed by an structure that contains three different types of layers: a convolutional layer that extracts features from the input (usually an image); a reduction (pooling) layer, which reduces the dimensionality of the extracted features through down-sampling while retaining the most important information (usually max pooling is applied [69]); and a fully connected classification layer, which provides the final result at the end of the network. Then, we focus on typical generic object detection architectures along with some … 5. There is a lack of end-to-end learning solutions and appropriate benchmarking mechanisms. In this paper, we provide a review of deep learning-based object detection frameworks. The rest of this article is organized as follows: Section 2 presents and compares previous surveys in the field of EDM; Section 3 describes the process carried out to retrieve the papers reviewed in this study, including a quantitative analysis of the papers gathered; Section 4 describes the main tasks in EDM, identifies the existing literature in each task, and describes the main datasets employed in the field; Section 5 presents the key concepts of DL, the main architectures, configurations, and frameworks, summarizing the characteristics (in terms of DL technologies) of the work done in EDM; Section 6 presents a discussion about the information compiled during this review work; finally, conclusions are presented in Section 7. The type of hidden layers defines the different neural network architectures, such as CNN, RNN, or LSTM (see Section 5.3). The research field of Educational Data Mining (EDM) focuses on the application of techniques and methods of data mining in educational environments. I review deep supervised learning (also recapitulating the history of backpropagation), unsupervised learning, reinforcement learning & evolutionary computation, and indirect search for short programs encoding deep and large networks. Based on the results of previous studies, the authors found that specific EDM techniques could offer the best means of solving certain learning problems, offering student-focused strategies and tools for educational institutions. The architectures include MLP (Multilayer Perceptron), LSTM (Long Short-Term Memory), WE (Word Embeddings), CNN (Convolutional Neural Networks) and variants (VGG16 and AlexNet), FNN (Feedforward Neural Networks), RNN (Recurrent Neural Networks), autoencoder, BLSTM (Bidirectional LSTM), and MN (Memory Networks). Networks without hidden layers are quiet limited in the patterns they can learn, and introducing more layers of linear units does not overcome this limitation. About The Paper. Regarding educational platforms, [26, 27] compiled several datasets with information about 30,000 students in Udacity (https://www.udacity.com). This can never occur with smooth classifiers by their definition. In order to perform a systematic review, the following scientific repositories were accessed: ACM Digital Library (https://dl.acm.org/), Google Scholar (https://scholar.google.es/), and IEEE Xplore (https://ieeexplore.ieee.org/). The largest dataset for the analysis of student dropout was presented in [31]. This paper analyzes and summarizes the latest progress and future research directions of deep learning. In this study, we provide a comprehensive review of deep learning-based recommendation approaches to enlighten and … This allowed expanding the number of relevant papers retrieved. Two datasets from the papers reviewed fall in the category of generating recommendation sequences for learning. Another issue of RNNs is that they require a high performance hardware to train and run the models. There are different RNN architectures (see LSTM in the next section). Using a batch size lower than the number of all samples has some benefits, such as requiring less memory (the network is trained using fewer samples in each propagation) and training faster (weights are updated after each propagation). Motivations: Deep neural networks are highly expressive models that have recently achieved state of the art performance on speech and visual recognition tasks. Other popular datasets are KDD Cup 2010 and the datasets available at DataShop repository. (xiii)Scientific inquiry: mostly targeted on researchers as the end users, but developed or tested theories can be used afterwards in other applications with different stakeholders. As deep neural networks are both time-consuming to train and prone to overfitting, a team at Microsoft introduced a residual learning framework to improve the training of networks that are substantially deeper than those used previously. The perturbed examples are termed as “adversarial examples”. The frameworks chosen for this task in the EDM field are word2vec [29, 45] and Glove (https://nlp.stanford.edu/projects/glove/) [40, 43]. This paper introduces PyTorch Geometric, a library for deep learning on irregularly structured input data such as graphs, point clouds, and manifolds, built upon PyTorch.
