deep learning review paper

This structure makes them convenient for dealing with sequences and lists, and thus one of their common uses is modeling text. This process continues, each layer building something more complex from the input received from the previous layer. This section presents an overview of the main datasets used for EDM in the reviewed papers, as well as other datasets developed for specific studies. In the first case, big data facilitates DL algorithms to generalize well. The Hybrid Imaging System Laboratory (HISLab) from the Smart Medical Information Research Center published a manuscript entitled “Review of deep learning for photoacoustic imaging” based on all the research using deep learning to solve various problems in photoacoustic imaging in recent years. The “deep” in DL refers to the multiple transformation layers and levels of representation that lie between the network inputs and outputs. Instructors could use this information to personalize and prioritize intervention for academically at-risk students. This writing summarizes and reviews the most intriguing paper on deep learning: Intriguing properties of neural networks. In order to perform a systematic review, the following scientific repositories were accessed: ACM Digital Library (, Google Scholar (, and IEEE Xplore ( Dataset: MNIST, ImageNet (AlexNet), 10M images sampled from Youtube (QuocNet). For instance, in an image classification task, the DL model can take pixel values in the input layer and assign labels to the objects in the image in the output layer. These hyperparameters refer to the number of hidden layers (depth) and the number of hidden units (width) in the network. LeCoRe combined both content-based and collaborative filtering techniques in its phases. To avoid this drawback, there are a number of techniques to automatically pick the best hyperparameters (such as grid search). Premal J Patel, 3Prof. In 2009, a new EDM survey was presented by Baker and Yacef [6]. Basic structure of a neural network. Another key factor in the development of DL has been the emergence of software frameworks like TensorFlow, Theano, Keras, and PyTorch, which have allowed researches to focus in the structure of the models rather than in low-level implementation details (see Section 5.5). The summary provided in Section 5.4 can give a hint of the starting point and suitable ranges of values for these hyperparameters in the development of new architectures. The Deep Review. Each neuron is connected to many others and the links between them can increment or inhibit the activation state of the adjacent neurons. In fact, it has been applied to all the EDM tasks covered by DL approaches: predicting students performance [21, 24, 53]; detecting undesirable student behaviors by predicting students dropout [28], predicting dialogue acts [33], modeling student behavior in learning platforms [29], and predicting engagement intensity [35]; generating recommendations [39]; and evaluation by doing stealth assessment [44], improving casual estimates from A/B tests [46], and automating essay scoring [41]. It is specialized in the development of CNNs for image-processing tasks. Machine learning, especially its subfield of Deep Learning, had many amazing advances in the recent years, and important research papers may lead to breakthroughs in technology that get used by billio ns of people. The first EDM survey identified in the literature was developed in 2007 by Romero and Ventura [3], which was further improved in 2010 [4] and 2013 [5]. This dataset was used in [29, 53]. By applying an imperceptible non-random perturbation to a test image, it is possible to arbitrarily change the network’s prediction. Dropout. This paper … The dataset consists of 5,000 unique learners and 49,202 unique course contents, resulting in a total of 2,140,476 enrollments. 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).

Besides providing a general introduction, all these topics will be characterized within the EDM domain, relating them to the papers reviewed. DCR finds most relevant review/s from a repository of common reviews generated using historical peer reviews. The second part of the section describes the main datasets used in the field, also grouped by the task addressed. Taking into account the current DL techniques applied to EDM, there are many open paths to explore new approaches to this field, such as the use or transfer learning for initialization of the neural networks (only used in [36]), the use of reinforcement learning [99], a promising learning technique that reduces the need for training data, and the application of architectures such as MN, DBN, and generative adversarial networks (GAN), in tasks where language or image generation are required [100]. In order for the network to learn, it is necessary to find the weights of each layer that provides the best mapping between the input examples and the corresponding objective outputs. In [34] the assumption was that if educational videos are not engaging, then students tend to lose interest in the course content. With respect to the number of units per hidden layer, the most common value in the papers reviewed is 200 [10, 11, 14, 15, 17–19, 49], followed by 100 [22, 40, 50], 64 [33, 35], 128 [21, 27], and 256 [26, 34]. In many applications, the sigmoid function is used as the activation function in these neurons. In this respect, more training data means almost always better DL models. Most approaches are application specific with no clear way to select, design or implement an architecture. The most repeated values are 0.2 [11, 27, 34] and 0.5 [19, 23, 41], followed by 0.3 [29, 36]. Unlike LSTMs, a RNN may leave out important information from the beginning while trying to process a paragraph of text to do predictions. Each circular node represents a neuron. EDM leverages e-learning platforms such as Learning Management Systems (LMS), Intelligent Tutoring Systems (ITS), and, in the last years, Massive Open Online Courses (MOOC), to obtain rich and multimodal information from student’s learning activities in educational settings. The inspection of individual units makes the implicit assumption that the units of the last feature layer form a distinguished basis which is particularly useful for extracting semantic information. Word embeddings are used in the area of natural language processing to map words (or phrases) to vectors of real numbers. (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. References [12, 30] used a corpus of programming exercises ( that contains 1,263,360 code submissions about multiple concepts such as loops, if-else statements and nested statements. A. Graves, “Generating sequences with recurrent neural networks,” 2013, D. Wang and E. Nyberg, “A long short-term memory model for answer sentence selection in question answering,” in, A. Ullah, J. Ahmad, K. Muhammad, M. Sajjad, and S. W. Baik, “Action recognition in video sequences using deep bi-directional lstm with cnn features,”. The taxonomy comprises thirteen tasks:(i)Predicting student performance: the objective is to estimate a value or variable describing the students’ performance or the achievement of learning outcomes. How can we train them? Any machine learning algorithm tries to assign inputs (e.g., an image) to target outputs (e.g., the “cat” label) by observing many input and output examples. A Review Paper on Machine Learning Based Recommendation System 1Bhumika Bhatt, 2Prof. (x)Generating recommendation: the objective is to make recommendations to any stakeholders, although the main focus is usually on helping students. J. Mao, W. Xu, Y. Yang, J. Wang, and A. L. Yuille, “Deep captioning with multimodal recurrent neural networks (m-rnn),” 2014, S. Venugopalan, M. Rohrbach, J. Donahue, R. Mooney, T. Darrell, and K. Saenko, “Sequence to sequence - Video to text,” in, P. Smolensky, “Information processing in dynamical systems: Foundations of harmony theory,” in, G. E. Hinton, “Deep belief networks,”. A series of works were published afterwards that were for [11–13, 19] or against [14–18] the claims in this paper. This function provides flexibility to neural networks, allowing to estimate complex nonlinear relations in the data and providing a normalization effect on the neuron output (e.g., bounding the resulting value between 0 and 1). This technique adds a fraction of the previous weight update to the current weight. At that time, I concluded that this daily activity of paper-reading is crucial to keep my mind active and abreast of the latest advancement in the field of deep learning. Report two counter-intuitive properties of deep learning neural networks. Weight Update. This information is used to adjust the weights of each connection in the network in order to reduce the error. The details about the DL implementation on each paper are described in Section 5. The training algorithm (e.g., BPTT) optimizes these weights based on the resulting network output error. In this case, the dataset contained information about the degree of success of 524 students answering several tests about probability. In general, networks with more hidden layers can learn more complex functions. Table 3 summarizes the works in EDM studied in this article (first column), the architectures implemented (second column), the baseline methods employed (third column), the evaluation measures used to compare DL approaches and baseline methods (fourth), and the performance achieved by DL methods in that comparison (fifth). FNNs are applicable to many areas where classical machine learning techniques have been applied, although major success have been achieved in computer vision [63] and speech recognition applications [64]. Our study of 25 years of artificial-intelligence research suggests the era of deep learning may come to an end. DL is undoubtedly the most trending research area in the field of artificial intelligence nowadays. In DL architectures, usually dozens or even hundreds of hidden layers are used, which can automatically learn as the model is trained with data. The use of machine learning (ML) has been increasing rapidly in the medical imaging field, including computer-aided diagnosis (CAD), radiomics, and medical image analysis. The main problem for the first task is that there is not a single “correct” sequence of learning items to recommend to a student, and this recommendation largely depends on the background knowledge, abilities, and goals of the learner. In this paper, we present a network and training strategy that relies … It was used by [36] for automatic eye gaze following in the classroom. Another issue of RNNs is that they require a high performance hardware to train and run the models. There is no analytical approach to setting these two parameters and choosing the best configuration for a task is sometimes a matter of trial and error. Finally, in the evaluation task different frameworks were built to help teachers in the grading process, primarily focused on automatic essay scoring and short answer grading. The problem in this case would be the impossibility to manually structure the large amount of data that comes from sources such as expert communities and educational blogs. Using a simple optimization procedure, the authors are able to find adversarial examples, which are obtained by imperceptibly small perturbations to a correctly classified input image, so that it is no longer classified correctly.

In [41] the authors followed a DL approach to identify the best feature representation to learn the relation between an essay and its assigned score. The output layer provides the predictions of the model. The use of deep layers of convolution, pooling and classification, has facilitated the emergence of new applications of CNN. Different machine learning techniques have been applied over time to analyze this data, but it has been in recent years that the use of Deep Learning techniques has emerged in the field of EDM. Reference [44] introduced a temporal analytics framework for stealth assessment that analyzed students’ problem-solving strategies in a game-based learning environment. Proves that the individual units has no semantic meaning: Reasonings that Deep NN is not stable to small perturbation on its input: Your email address will not be published. Whereas shallow neural networks (with a single hidden layer) can in theory approximate any function (according to the universal approximation theorem [93]) many empirical results in different tasks and domains demonstrate that adding more hidden layers improves the performance of the network. The following sections describe the foundations of neural networks, training process, main architectures, hyperparameter tuning, and frameworks for developing DL models. There are different RNN architectures (see LSTM in the next section). In this section, the most popular architectures, their common tasks, and their use in EDM will be described. Detecting undesirable student behaviors: the focus here is on detecting undesirable student behavior, such as low motivation, erroneous actions, cheating, or dropping out. The rest of the paper is organized as follows. Many research fields have benefited from applying these technologies, and EDM is not an exception. One way to do this initialization is assigning random values, although this method can potentially lead to two issues: vanishing gradient (the weight update is minor and the optimization of the loss function is slow) and exploding gradient (oscillating around the minima). Reference [34] also developed a multimedia corpus for the analysis of liveliness of educational videos. This makes the training process difficult in several ways: this architecture cannot be stacked into very deep models and cannot keep track of long-term dependencies. Their paper titled, “A Deep Neural Network Model to Predict Criminality Using Image Processing” was supposed to … Our review begins with a brief introduction on the history of deep learning and its representative tool, namely, the convolutional neural network. Experimental results demonstrated the effectiveness of the method proposed. Posted by Mohamad Ivan Fanany Printed version This writing summarizes and reviews the most intriguing paper on deep learning: Intriguing properties of neural networks. Their contribution to the activation of neurons in the next layer is temporally removed on the forward pass and weight updates are not applied to the neuron on the backward pass [97]. The authors obtained inconclusive results regarding the benefits of using embeddings with respect to traditional n-grams. The result of this function indicates how well is working the model for the specified examples. Some of these datasets are related to how students learn (for example, the success of students developing different types of exercises) and others to how student interact with digital learning platforms (e.g., clickstream or eye-tracking data in MOOCs). One of the main disadvantages of RNNs is the issue of vanishing gradients, where the magnitude of the gradients (values used to update the neural network weights) gets exponentially smaller (vanish) as the network back propagates, resulting in a very slow learning of the weights in the lower layers of the RNN. Copyright © 2019 Antonio Hernández-Blanco et al. Based on the analyzed work, we suggest that deep learning approaches could be automatic eye gaze following for classroom observation video analysis,” in, A. It was the most widely used library for DL before the arrival of other competitors such as Tensorflow, Caffe, and PyTorch. For each possible score in the rubric, student responses graded with the same score were collected and used as the grading criteria. A recent study is described in [8]. Authored by Alex Krizhevsky, Ilya Sutskever, and Geoffrey Hinton, and titled ImageNet Classification with Deep Convolutional Networks, this paper is regarded as one of the most influential papers in the field. Reference [25] proposed a model to categorize students into high, medium and low, to determine their learning capabilities and help them to improve their study techniques. 2019, Article ID 1306039, 22 pages, 2019., 1Technical University of the North, Ecuador. In the task of predicting student performance, a large sample of the papers analyzed were devoted to compare the performance of BKT (probabilistic) and DKT (deep learning) models, resulting in an interesting discussion between traditional and deep learning approaches (see Section 5.3.4). Results showed an improvement with respect to other approaches requiring feature engineering. The paper developed a hybrid model of Deep Convolutional Neural Nets and Conditional Neural Fields. The most widely used activation functions are sigmoid, tanh (hyperbolic tangent), and ReLU (Rectified Linear Unit). In the later, the authors analyzed more than 300 studies carried out before 2010, identifying eleven categories or tasks in EDM: analysis and visualization of data, providing feedback for supporting instructors, recommendations for students, predicting student’s performance, student modeling detecting undesirable student behaviors, grouping students, social network analysis, developing concept maps, constructing coursewares, and planning and scheduling. A thorough study of DL techniques were also provided in this work, starting with an introduction to the field, an analysis of the types of DL architectures used in every task, a review of the most common hyperparameter configurations, and a list of the existing frameworks to help in the development of DL models. The first part of this section shows taxonomy of the tasks addressed by EDM systems. The latest advances in deep learning technologies provide new effective paradigms to obtain end-to-end learning models from complex data. EDM is concerned with developing, researching, and applying machine learning, data mining, and statistical methods to detect patterns in large collections of educational data that would otherwise be impossible to analyze [1]. The following subsections present each task and the works related in more detail. Finally, for the specific analysis of sociomoral reasoning maturity, [37] developed a corpus of 691 texts in French manually coded by experts, stating the level of maturity in a range from 5 (highest) to 1 (lowest). J. Whitehill, K. Mohan, D. Seaton, Y. Rosen, and D. Tingley, “Delving deeper into MOOC student dropout prediction,” 2017, W. Xing and D. Du, “Dropout Prediction in MOOCs: Using Deep Learning for Personalized Intervention,”, W. Min, J. Nevertheless, these results are not exempt from controversy. Nevertheless, a general advice with deep neural networks is to take many small steps (smaller batch sizes and learning rates) instead of fewer larger ones, although this is a design trade-off that requires experimentation. In the last years, different surveys have focus in different aspects of EDM systems. Other relevant frameworks for DL, not used in any of the presented works, are Caffe2 (, Deeplearning4j (, MXNet (url, Microsoft Cognitive Toolkit (, and Chainer ( This type of neural network has been used for image recognition, information retrieval and natural language understanding, among other tasks. The one that started it all (Though some may say that Yann LeCun’s paper in 1998 was the real pioneering publication). “Specific” means that the dataset has been created for a specific study, and “General” means that it has been used in different publications. Most approaches are application specific with no clear way to select, design or implement an architecture. Most of the papers reviewed used SGD in the training phase [10, 18–20, 22, 27, 31–33, 36, 40, 41, 49, 50]. The most-cited papers in EDM between 1995 and 2005 were listed, discussing their influence on the EDM community. Reference [40] proposed a DL-based automated grading model. Among those analyzed, learning rate, batch size, and the stopping criteria (number of epochs) are considered to be critical to model performance. A DL model was implemented to provide predictions based on the top features identified. This process is difficult and time-consuming since the correct choice of features is fundamental to the performance of the system [57]. In fact, there were a specific competition for this task called ASAP ( whose dataset has been used in different works [21, 40, 54]. One of the challenges that has gained more attention in this area is knowledge tracing. Given a question and a set of candidate answers, the task is to identify … These data was extracted from the Cognitive Algebra Tutor system during 2005 and 2006 [51]. The application of data mining techniques to educational environments has been an active research field in the last few decades, gaining much popularity in recent times thanks to the availability of online datasets and learning systems. Regarding DL architectures, LSTMs have been the most used approach, both in terms of frequency of use (59% of the papers used it) and variety of tasks covered, since it was applied in the four EDM tasks addressed by the works analyzed. The second relevant aspect of this work is the study of existing datasets used by DL models in educational contexts. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The baseline methods are SVD (Singular Value Decomposition), Slope One, K-NN (K-Nearest Neighbors), Majority class, RF (Random Forest), SVM (Support Vector Machine), N-grams, Random guess, LinReg (Linear Regression), DT (Decision Tree), NB (Naïve Bayes), LogReg (Logistic Regression), HMM (Hidden Markov Model), IOHMM (Input Output HMM), BKT (Bayesian Knowledge Tracing), IBKT (Intervention BKT), PFA (Principal Factor Analysis), Majority voting, CRF (Computational Random Fields), LSA (Latent Semantic Analysis), LDA (Latent Dirichlet Allocation), SVR (Support Vector Regression), BLRR (Bayesian Linear Ridge Regression), AdaBoost, GTB (Gradient Tree Boosting), GNB (Gaussian Naïve Bayes), IRT (Item Response Theory), TIRT (Temporal IRT), and HIRT (Hierarchical IRT). The third hyperparameter mentioned, the number of epochs, must also be properly adjusted to avoid the problem of overfitting. The paper provides a systematic review on the application of deep learning in SHM. DL models include hyperparameters, which are variables set before optimizing the parameters (weights and bias) of the models. There are different ways to determine the number of epochs employed to train the algorithms. To these end, a DL-based dialogue act classifier that utilizes these three data sources was implemented. Batch sizes used in the works reviewed include 10 [31, 38], 32 [19, 27, 33, 41], 48 [25], 100 [10, 11, 18], 500 [37], and 512 [23]. It includes additional information such as clickstream data about answers to quiz questions, play/pause/rewind events on lecture videos, and reading and writing to the discussion form.
