Manual processing and summarization of large volumes of textual data is a very difficult, expensive, time-consuming, and impossible process for human users. Text summarization systems are divided into extractive and abstract categories. In the extractive summarization method, the final summary of a text document is extracted from the important sentences of the same document without any kind of change. In this method, it is possible to repeat a series of sentences repeatedly and interfere with pronouns. But in the abstract summarization method, the final summary of a textual document is extracted from the meaning of the sentences and words of the same document or other documents. Many of the performed works have used extraction methods or abstracts to summarize the collection of web documents, each of which has advantages and disadvantages in the results obtained in terms of similarity or size. In this research, by developing a crawler, extracting the popular text posts from the Instagram social network, suitable pre-processing, and combining the set of extractive and abstract algorithms, the researcher showed how to use each of the abstract algorithms. and used extraction as a supplement to increase the accuracy and accuracy of another algorithm. Observations made on 820 popular text posts on the Instagram social network show the accuracy (80%) of the proposed system.","PeriodicalId":109390,"journal":{"name":"2023 6th International Conference on Pattern Recognition and Image Analysis (IPRIA)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125002503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since there is no reference image, this is a challenging and unresolved issue. Convolutional neural networks (CNNs) have gained popularity in recent years and have outperformed many traditional techniques in the field of image processing. In order to overcome overfitting, a large percentage of deep learning based IQA methods work with tiny image patches and assess the quality of the entire image based on the average scores of patches. Patch extraction is one of the most crucial elements of CNN-based methods in quality assessment problems. Assuming that visual perception in humans is well suited to extract structural details from a scene, we analyzed the effect of feeding informative and structural patches to the quality framework. In this paper, a method for structural patch extraction is presented, which is based on the variance values of each patch. The obtained results show that the presented method has an acceptable improvement compared to the random patch selection. The proposed model has also performed well in cross-dataset experiments on common distortions, indicating the model's high generalizability. Additionally, the test was run on the flipped images, and the outcomes are satisfactory.","PeriodicalId":109390,"journal":{"name":"2023 6th International Conference on Pattern Recognition and Image Analysis (IPRIA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132382640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to constantly identify and assess scientific outputs in order to learn more about the situation. One of the methods used for evaluating scientific research activities is scientometrics, which has many applications in describing, explaining and predicting the scientific status of researchers and research centers in various national and international fields. It also provides efficient methods for monitoring and ranking organizations, researchers, journals and countries. On the other hand, in recent years, the use of various scientometric techniques, including co-word analysis, co-authorship network and scientific network, has been of great help in discovering the direction of researchers' production in scientific domain and its hidden and overt dimensions. One of the most popular areas since the COVID-19 epidemic started, has been research the use of artificial intelligence and especially machine learning techniques in the prediction, diagnosis and treatment of this disease. In this regard, 2659 documents from the PubMed citation database since the start of the COVID-19 epidemic have been reviewed.

This assessment should mimic human judgments. Considering the complexity of the human visual system, it is challenging to model human perception. On the other hand, the recent low-level vision task approaches, mostly based on supervised deep learning, require an appropriate loss for the backward pass. The per-pixel loss, such as MSE and MAE, between the output of the network and the ground-truth images were among the first choices. More complicated and common similarity measures in which the error is computed in a hand-designed feature space are also employed. Furthermore, Deep Perceptual Similarity (DPS) metrics, where the similarity is measured in the deep feature space, also have promising results. This feature can be selected from a pre-trained or optimized model for the task at hand. Recently many studies have been conducted to thoroughly investigate DPS. In this research, we provide an in-depth analysis of the pros and cons of DPS in assessing the full reference quality assessment. In addition, to compare different similarity measures, we propose a metric which aggregates various desired factors. Based on our experiment, it can be concluded that perceptual similarity is not directly related to classification accuracy. It is discovered that the outliers mostly contain high-frequency elements.

Thus, the development of a feasible approach for high-performance emotion recognition might enhance human-computer interaction. Deep learning methods have enhanced the performance of emotion recognition systems in comparison to other current methods. In this paper, a multimodal deep convolutional neural network (CNN) and bidirectional long short-term memory (BiLSTM) network are proposed, which fuses the audio and visual cues in a deep model. The spatial and temporal features extracted from video frames are fused with short-term Fourier transform (STFT) extracted from audio signals. Finally, a Softmax classifier is used to classify inputs into seven groups: anger, disgust, fear, happiness, sadness, surprise, and neutral mode. The proposed model is evaluated on Surrey Audio-Visual Expressed Emotion (SAVEE) database with an accuracy of 95.48%.

It is usually possible to detect respiratory diseases early by listening to the lung sounds with a stethoscope. In reality, lung sound analysis is a time-consuming and difficult task that depends on medical skills and recognition experience. Recent advances in automatic respiratory sound recognition and classification have attracted more attention. The outbreak of COVID-19 throughout the world and the high patient numbers have placed a great deal of pressure on medical professionals. A smart algorithm is therefore a necessity to provide a faster and more accurate detection of lung infections by automatically processing the sounds of the lungs. This paper proposes two new lung sound feature extraction, maximum entropy Gabor filter bank (MAGFB), and maximum entropy Mel filter bank (MAMFB). The classification is performed by a deep neural convolution network (DCNN) by using 50% of data for training the classifier. The filter banks have been substituted, instead of the convolutional layers. Experiments were conducted on the ICBHI 2017 Challenge dataset (with eight classes). The proposed method has a better performance compared to famous methods such as MFCC and Wavelet transform. Particularly, the performance of the second method is significant.
