In this paper, a regional vocabulary-based application-oriented Neural Machine Translation (NMT) model is proposed over the data set of emails used at the University for communication over a period of three years. A state-of-the-art Sequence-to-Sequence Neural Network for ML → EN (Malay to English) and EN → ML (English to Malay) translations is compared with Google Translate using Gated Recurrent Unit Recurrent Neural Network machine translation model with attention decoder. The low BLEU score of Google Translation in comparison to our model indicates that the application based regional models are better. The low BLEU score of English to Malay of our model and Google Translation indicates that the Malay Language has complex language features corresponding to English.","PeriodicalId":294293,"journal":{"name":"2020 2nd Symposium on Signal Processing Systems","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133854331","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}

Firstly, the characteristics of the image in slam are analyzed and the image preprocessing is carried out to reduce the gray mutation. Secondly, in order to meet the real-time requirements, the feature descriptors of sift are simplified to improve the speed. Using the continuity of slam image, the method of pixel neighborhood matching reduces the time of feature matching and reduces the error matching rate of repeated texture. GPU is used to implement the Improved SIFT feature algorithm. Finally, the simulation results show that the trajectory accuracy is improved by more than 35% and the image processing time is about 12ms. At the same time, the system accuracy is improved.","PeriodicalId":294293,"journal":{"name":"2020 2nd Symposium on Signal Processing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115254350","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}

Specifically, we build a novel framework for the joint extraction model of opinion target and target-oriented opinion words feedback, which aims to extract the opinion target and corresponding opinion words. In order to accomplish the TOWE task more effectively, we proposed an IO-LSTM+Transformer structure, termed IOT, which has excellent performance in domain-specific datasets when combined with the BERT pre-training model. To validate the effectiveness of our model, we develop a pipeline model for comparison. Experiment results show that our model can extract the pair of opinion target and opinion words from the sentence more effectively than the pipeline model.

Automatic segmentation of esophagus and esophageal tumor from computed tomography (CT) images is a challenging problem, which can assist in the diagnosis of esophageal cancer. In this paper, DB M-Net is proposed for the segmentation of esophagus and esophageal tumor from CT images, which combines M-Net modified from U-Net with an approximate function for binarization called differentiable binarization (DB). We construct the multi-scale input layers and the multi-level output layers in the network to facilitate features fusion, and DB is performed to enhance the robustness. Fewer parameters are applied in our DB M-Net but the network achieves a better performance.

The effective detection the location of breast cancer from the ultrasound images can assist doctors in diagnosing breast cancer. Diverse morphology, blurred edges, and small amount of data causes great difficulty in the detection of breast cancer. Deep learning is very advantageous when facing these problems. However, the problems of training on small sample datasets and the imbalance of positive and negative samples are problems that need to be solved. In order to improve the accuracy of ultrasound breast cancer detection, a small sample breast cancer detection method based on data augmentation and corner pooling is proposed in this paper. In this method, we propose a way for solving over-fitting of small samples and solving the imbalance problem of positive and negative samples. Data augmentation module based on geometric and noise transformation is proposed to solve the problem of small samples, and detection module based on focal loss and corner pooling is proposed to solve the problem of imbalance samples. The experiment found that the method used in this paper has more advantages than the mainstream methods in difficult to distinguish samples.

In this paper, we use single-modality, transcribed text data, for depression detection. We proposed a decision fusion model which combines Bert text embedding of interview transcript and key phrases recognition. Text embedding module is composed of Bert embedding model and LSTM network. Key phrases recognition module recognizes words such as “depression”, “cannot sleep” that are believed to be valuable in improving the recognition accuracy.

Firstly, we apply Multi-task Cascaded Convolutional Networks for eye detection, which is light and fast. Then we propose Weighted FCN and Hough Transform to segment the iris, even if the iris is partially occlusive. Finally, we design a calibration scheme to correct the iris radius in the real world.

Medical treatment and mental supports are considering factors in rehabilitation process for opioid addicts. In this process families and friends play an important role in supporting and help the addict to stay clean. However, they may not know the best action to take due to lack of knowledge or certainty. Therefore, there are situations that addicts tend to use social media as a question/answering platform to seek answer for an inquiry. Unfortunately, It is often difficult to search over pages or different forums for a quick answer and it can be time-consuming, confusing and ultimately frustrating for the addicts. Hence, We propose a novel chatbot that is integrated with state-of-the-art deep learning techniques to retrieve an instant answer for a user’s query from Reddit social media. Our experiment illustrates that the chatbot provides answers in scenarios that there is no exact matched question in the discussion forums but there are questions with semantic similarities to the user query. Consequently, we illustrate real use cases where our chatbot retrieves responses from Reddit social media forums.","PeriodicalId":294293,"journal":{"name":"2020 2nd Symposium on Signal Processing Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131736868","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}

So, how to filter noise and purify web news content to improve the accuracy of web news classification has become a challenging problem. In this paper, we proposed a web news classification method via fusing noise detection, BERT-based semantic similarity noise filtering and convolutional neural network (NF-CNN) to solve the problem.
