We aim at the semantic segmentation in the endoscopy surgery scenario because semantic segmentation is the first step for a computer to grasp what shows up in the vision of an endoscope. However, modern Deep Learning algorithms need myriads of training data. Since data of the endoscopy surgery scene is relatively scarce, the performance of existing algorithms is thus rather limited. Therefore, we tried to solve the problem of training a semantic segmentation network with few data in this work. We propose a proof-of-concept system offering the ability to enlarge the dataset and improve the performance. The system aims to synthesize a pair of training data in a single pass and provides a sufficient amount of data to train a network. We evaluated our method using the dataset provided by MICCAI 2018 Robotic Scene Segmentation Sub-Challenge. Our method yielded 11.79% mIoU improvement in recognizing anatomical objects and 2.2% mIoU in recognizing surgical instruments. Recognizing anatomical objects accurately would definitely benefit CAS. Preliminary results suggest our method helps the classifier become more robust and accurate even if not having large amount of data.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130903970","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}

To solve this problem and improve the efficiency of recommendation systems, we propose a new content-based CF approach based on item similarity. We apply the model in the movie domain and extract features such as genres, directors, actors, and plots of the movies. We use the Jaccard coefficient index to covert the extracted features such as genres, directors, actors to the vectors while the plot feature is converted to the semantic vectors. Then, the similarity of the movies is calculated by soft cosine measure based on vectorized features. We apply the word embedding model (i.e., Word2Vec) for representing the plots feature as semantic vectors instead of using traditional models such as a binary bag of words and a TF-IDF vector space. Experiment results show the superiority of the proposed system in terms of accuracy, precision, recall, and F1 scores in cold-start conditions compared to the baseline systems.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130423259","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}

The conversation can be divided into homogeneous segments using a typical SCD system or speaker diarization system in which the segments are partitioned according to a speaker identity. When the d-vectors are used to identify or verify the speakers with deep neural network model, they are often considered insufficient to train model for detecting the speaker changes by using only acoustic information. There are few dedicated datasets for system training, so the progress of the SCD study is slow and the performance is poor. Therefore, we presented data augmentation method based on TIMIT dataset to suit for the system, and we also proposed several methods to represent d-vectors for SCD systems and their preliminary results. In the proposed data augmentation method, the boundary information of speakers is transformed into probability according to the offset in a given frame and collected in the segment. To model the boundaries of the speakers, we concatenate two random speech sentences dedicated to speech recognition system. The preliminary experimental results, specifically recall percentage, shows the possibility of the proposed approaches. In the future, we will add linguistic information to the proposed classification system, or improve the system to use hybrid system of d-vector and frame vectors, or convolutional networks.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133299049","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}

Analysis of genome sequences, especially variant calling, is exceedingly computationally intensive, as it demands large storage capacity, computing power, and high-speed network to reduce the processing time. In the case of DeepVariant, an open-source software package which employs a deep neural network (DNN) to calls genetic variants, it took four hours to complete the analysis on a workstation with a high-performance GPU device to accelerate the DNN. Therefore, we profiled the performance of DeepVariant and refactored the code to reduce the time and cost of the NGS pipeline with a series of code optimization works. As a result, our distributed version of DeepVariant can finish the same job within 8 minutes on 8 dual-CPU nodes and 8 GPUs, which outperforms commercial versions in the market.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123425916","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}

Conventional compression techniques require human expert to setup parameters to explore the design space and iterative based pruning requires heavy training which is sub-optimal and time consuming. Given a CNN model, we propose deep reinforcement learning [8] DQN based automated compression which effectively turned off kernels on each layer by observing its significance. Observing accuracy, compression ratio and convergence rate, proposed DQN model can automatically re- activate the healthiest kernels back to train it again to regain accuracy which greatly ameliorate the model compression quality. Based on experiments on MNIST [3] dataset, our method can compress convolution layers for VGG-like [10] model up to 60% with 0.5% increase in test accuracy within less than a half the number of initial amount of training (speed-up up to 2.5×), state- of-the-art results of dropping 80% of kernels (compressed 86% parameters) with increase in accuracy by 0.14%. Further dropping 84% of kernels (compressed 94% parameters) with the loss of 0.4% accuracy. The first proposed Auto-AEC (Accuracy-Ensured Compression) model can compress the network by preserving original accuracy or increase in accuracy of the model, whereas, the second proposed Auto-CECA (Compression-Ensured Considering the Accuracy) model can compress to the maximum by preserving original accuracy or minimal drop of accuracy. We further analyze effectiveness of kernels on different layers based on how our model explores and exploits in various stages of training.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"186 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132584112","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}

Those benefits help to narrow down the space for searching and speed up the process for matching for applications such as automatic fingerprint identification systems (AFIS). However, achieving high prediction accuracy without human intervention (such as preprocessing and hand-crafted feature extraction) is currently and potentially a challenge. Therefore, this paper presents a deep learning method to automatically and conveniently estimate gender from fingerprint-images. In particular, the VGG-19, ResNet-50 and EfficientNet-B3 model were exploited to train from scratch. The raw images of fingerprints were fed into the networks for end-to-end learning.

Our experimental results showed that by comparing between those state-of-the-art models (VGG-19, ResNet-50 and EfficientNet-B3), EfficientNet-B3 model achieved the best accuracy of 97.89%, 69.86% and 63.05% for training, validating, and testing, respectively.","PeriodicalId":326100,"journal":{"name":"Proceedings of the International Conference on Research in Adaptive and Convergent Systems","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131822569","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}
