Due to an increase in research, more information has become available regarding the potential causes for cancer, including non-coding elements such as lncRNAs. This new knowledge can be discovered through machine learning methods that can extract new information from data such as gene expression profiles and identify new cancer-associated genes. For this work we use two different machine learning algorithms, random forests and support vector machines. The models were trained and we tested fine-tuning methods including: balancing and feature selection. The predictors with the highest metrics were: balanced RF with Boruta (AUC-ROC: 0.9696) and the balanced SVM with recursive feature elimination (AUC-ROC: 0.9710). These models were used to identify new potential lncRNA driver-like genes from protein coding expression data. The predicted candidates were then functionally annotated using disease ontologies and molecular function ontologies to determine their enrichment in cancer related processes. These processes included prostate cancer and glycosaminglycan binding, a potential tumor therapeutic target.","PeriodicalId":103662,"journal":{"name":"2019 International Conference on Computational Science and Computational Intelligence (CSCI)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122418280","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 main novelty is that the alignment vectors for each phase are taken as the outputs, and are trained directly to select the indices.

Data recovery can be a difficult topic to cover without a system or organization to the different methods of recovery. The following manuscript offers a structure for introducing data recovery in a digital forensics or information technology course and a method for evaluating the admissibility of recovered files as court evidence based on how the data were recovered. This offers both a framework for teaching data recovery and a way for discussing evidence admissibility. The five levels of destruction paradigm is a result of over a decade of teaching digital forensics in vocational and academic environments in a computer science program. The authors offer up this paradigm in hopes it will be useful to other computer science and digital forensics educators.","PeriodicalId":103662,"journal":{"name":"2019 International Conference on Computational Science and Computational Intelligence (CSCI)","volume":"79 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132531931","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}

In our previous work, the emphasis was placed on denoising the input dataset by adding colored noise before processing. In that work, the evaluation made with the empirical robustness score, resulted in a 1% improvement on average for individual noise and a 3.74% improvement on average for ensemble noise. The aim of this paper is to demonstrate the effective robustness of a well-designed radial basis function neural network in tackling adversarial examples. With the empirical robustness as a metric, the results show a 72.5% increase with Fast Gradient Sign Method (FGSM) attack on the MNIST dataset in comparison to a simple deep network and a 6.4 % increase with FGSM on the CIFAR10 dataset.","PeriodicalId":103662,"journal":{"name":"2019 International Conference on Computational Science and Computational Intelligence (CSCI)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132818978","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}

In this research, we explore the concept of statistically significant association patterns to induce an initial partition on data for deriving manifolds. Manifolds are hyperplanes embedded in low dimensions. The advantage of this novel technique is a bootstrap on data clusters that reveals statistical associations from the information-theoretic perspective. As an illustration, the proposed technique is applied to a real data set of diabetes patients. An assessment on the proposed technique is performed to investigate the effect of bootstrap based on association patterns.

A critical bottleneck in most scenarios in cloud computing is the high degree of unpredictability with respect to resource availability and network bandwidth, which may lead to low Quality of Service (like low response times), which can be improved by Load Balancing. Load balancing concerns with efficiently distributing incoming network traffic across a group of servers. This ensures no single server bears too much demand, and thus the availability of applications and websites for users is increased. Due to the huge state-space of such a problem, implementing task scheduling algorithms in load balancing can be very effective. In this paper, we propose a hybrid intelligent approach to load balancing: a Genetic Algorithm module arranges the jobs randomly, and a fuzzy logic module builds the objective function for determining busy states of servers according to their RAM and CPU task queues. The fuzzy input variables include the satisfaction degree and the start and end times of the service, and the fuzzy output is service availability. Computational experiments showed that the best solution was obtained within half of the planned execution time, which leads to higher user satisfaction degree.","PeriodicalId":103662,"journal":{"name":"2019 International Conference on Computational Science and Computational Intelligence (CSCI)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115342550","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}
