Abstract:Sarcasm is a state of speech in which the speaker says something that is externally unfriendly with a purpose of abusing/deriding the listener and/or a third person. Since sarcasm detection is mainly based on the context of utterances or sentences, it is hard to design a model to proficiently detect sarcasm in the domain of natural language processing (NLP). Despite the fact that various methods for detecting sarcasm have been created utilizing statistical machine learning and rule-based approaches, they are u… Show more
“…The proposed model employs pre-processing, pre-training, and classification phases, utilizing three sentence-based techniques to provide the final categorization of sarcastic or non-sarcastic comments. Kavitha et al [19] developed a novel deep learningbased sarcasm detection classification model (DLE-SDC) that involves a pre-processing stage, Glove-based word vector representation, a combination of convolutional neural network and recurrent neural network (CNN-RNN) based classification, and an algorithm for teaching and learning based optimization (TLBO) for hyperparameter tuning. The model is validated using a benchmark dataset and evaluated based on precision, recall, accuracy, and F1 score.…”

“…Sarcasm [14][15][16][17][18], a statement conveying the as it can invert the true sentiment of a statement. Despite being a popular research topic, sarcasm detection [19][20][21][22][23][24][25][26] is crucial as sentiment analysis can misinterpret sarcastic sentences, leading to inaccurate sentiment classifications. The difficulty lies in the nuanced nature of human emotions and expressions conveyed through text, making automatic sarcasm detection a challenging task within natural language processing (NLP) [27,28].…”

“…CNN with recurrent neural network (CNN-RNN) technique is utilized to detect and classify sarcasm [28]. In order to boost the detection outcomes of the CNN+RNN technique, a hyperparameter tuning process utilizing a teaching and learning-based optimization (TLBO) algorithm is employed in such a way that the classification performance gets increased.…”
Identifying an optimal basis for a linear programming problem is a challenging learning task. Traditionally, an optimal basis is obtained via the iterative simplex method which improves from the current basic feasible solution to the adjacent one until it reaches optimal. The obtained result is the value of the optimal solution and the corresponding optimal basis. Even though learning the optimal value is hard but learning the optimal basis is possible via deep learning. This paper presents the primal-optimal-binding LPNet that learns from massive linear programming problems of various sizes casting as all-unit-rowexcept-first-unit-column matrices. During the training step, these matrices are fed to the special row-column convolutional layer followed by the state-of-the-art deep learning architecture and sent to two fully connected layers. The result is the probability vector of non-negativity constraints and the original linear programming constraints at the optimal basis. The experiment shows that this LPNet achieves 99% accuracy of predicting a single binding optimal constraint on unseen test problems and Netlib problems. It identifies correctly 80% LP problems having all optimal binding constraints and faster than cplex solution time.
