In this paper, we modify the posteriors generated at the output layer of LSTM according to the manner of articulation detection. The modified posteriors are given to the conventional decoding graph to minimize the false substitutions and insertions.

{"title":"Predicting Secondary Equity Offerings (SEOs) Using Machine Learning","authors":"Linlin Cui, Jianhua Chen, Wentao Wu","doi":"10.1109/ICMLA.2018.00198","DOIUrl":"https://doi.org/10.1109/ICMLA.2018.00198","url":null,"abstract":"This paper explores the application of machine learning techniques in finance to predict if a publicly-traded firm will issue a Seasoned Equity Offering (SEO) by analyzing the firm's 10-Q filing documents with Security and Exchange Commissions (SEC). Specifically, using the information content in the Management Discussion and Analysis section (MD&A) of 10-Q filings, we train five different algorithms, including Logistic Regression (LR), Support Vector Classification (SVC), Multinomial Naïve Bayes (NB), Artificial Neural Network (ANN) and Random Forest (RF). Two types of features, unigrams and phrases are considered. Term frequency-inverse document (TF-IDF) scores are used as independent variables in these models. Experimental results show that the accuracy of phrases-only models has a range of 0-2% improvement for LR, NB, and RF compared with unigrams-only models. The accuracy of phrase-only model for SVC is close to that of unigrams-only model. The 74.53% accuracy of unigrams-only model for SVC classifier performs the best among all tested classifiers. The precision of all models varies between 60% and 75%, while the recall varies between 55% and 85%. Further, we tune model parameters of one linear model (LR) and one non-linear model (RF) to see how these parameters will impact the models' performance. Finally, we apply RF to find the most important features on prediction and find that \"merger\" is the most important feature in both unigrams-only model and phrases-only model. We conclude that text mining with SEC financial document filings could be an effective tool to predict important corporate events such as SEO.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"25 3 1","pages":"1219-1224"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79714174","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}

Making use of such data to help physicians to evaluate the mortality risk of in-hospital patients provides an invaluable source of information that can ultimately help with improving healthcare services. In particular, quick and accurate predictions of mortality can be valuable for physicians who are making decisions about interventions. In this work we introduce the use of a predictive Deep Learning model to help evaluate the mortality risk for in-hospital patients. Stacked Denoising Autoencoder (SDA) has been trained using a unique time-stamped dataset (King Abdullah International Research Center – KAIMRC) which is naturally imbalanced.

It is still the epileptic patients' hope to find an effective way of preventing seizures to improve the quality of their lives. In this paper, using an innovative mixing of unsupervised and supervised deep learning techniques, we propose a novel epileptic seizure prediction system using electroencephalogram (EEG) recordings from the human brains. The proposed system is built upon classifying between the interictal and the preictal brain states. The proposed system uses two-dimensional deep convolutional autoencoder for learning the best discriminative spatial features from the multichannel unlabeled raw EEG recordings. A Bidirectional Long Short-Term Memory recurrent neural network is used for classification based on the temporal information. To help achieve faster learning and reliable convergence for our system, the transfer learning technique is used for initializing the weights for the patient-specific networks. Within, up to one hour of prediction window, our system achieved an average sensitivity of 94.6% and average low false prediction alarm rate of 0.04FP/h which makes it one of the most efficient among state-of-the-art methods.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"17 1","pages":"1186-1191"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87288418","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}

Shan, Yaodong Du, Ming Zhang","doi":"10.1109/ICMLA.2018.00179","DOIUrl":"https://doi.org/10.1109/ICMLA.2018.00179","url":null,"abstract":"Breast cancer is one of the deadliest cancers that cause women death globally. Ultrasound imaging is one of the commonly used diagnostic tools for detection and classification of breast abnormalities. In the past decades, computer-aided diagnosis (CAD) systems have been developed to improve the accuracy of diagnosis made by radiologists. In particular, automatic breast ultrasound (BUS) image segmentation is a critical step for cancer diagnosis using CAD. However, accurate tumor segmentation is still a challenge as a result of various ultrasound artifacts. This paper developed a novel segmentation framework based on deep learning architecture u-net, for breast ultrasound imaging. U-net is a convolutional neural network architecture designed for biology image segmentation with limited training data. It was originally proposed for neuronal structure segmentation in microscopy images. In our work, we modified and improved the method for BUS image segmentation. On a database of 221 BUS images, we first applied pre-processing techniques including contrast enhancement and speckle reduction to improve the image quality. Then the u-net model was trained and tested through two-fold cross-validation. In order to increase the size of training set, data augmentation strategies including rotation and elastic deformation were applied. Finally, a post-processing step that removed noisy region(s) from the segmentation result finalized the whole method. The area error metrics, dice coefficient, and similarity rate were calculated to evaluate the performance on the testing sets. We compared our method with another two fully automatic segmentation methods on the same dataset. Our method outperformed the other two significantly with the dice coefficient = 0.825 and similarity rate = 0.698. Experiment results showed that the modified u-net method is more robust and accurate in breast tumor segmentation for ultrasound images.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"11 1","pages":"1103-1108"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85251957","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}

Although, there are few proposed models for predicting productivity, there is no consistent conclusion regarding which model is the superior. Therefore, instead of building a new productivity prediction model, this paper presents a new ensemble construction mechanism applied for software project productivity prediction. Ensemble is an effective technique when performance of base models is poor. We proposed a weighted mean method to aggregate predicted productivities based on average of errors produced by training model. The obtained results show that the using ensemble is a good alternative approach when accuracies of base models are not consistently accurate over different datasets, and when models behave diversely.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"25 1","pages":"1427-1431"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90666364","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}

We collected all clinical trial data from the National Cancer Institute website, and applied word2vec to learn word embeddings for eligibility criteria. Criteria encoded with word embeddings were then fed into a multi-layer convolution neural network (CNN) for classification. To overcome the challenge of non-existing class labels, we designed an active learning algorithm that uses uncertainty cluster sampling to navigate the dataset and strategically propagate obtained labels to expand the training set for CNN. Experimental results show that word2vec successfully learns meaningful embeddings in criteria data, and the active deep learning approach reports a significant lower error rate in classification than the baseline k-nearest neighbor method.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"1 1","pages":"305-310"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89557533","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 has been shown that single-agent RL can be accelerated within a cooperative multi-agent scenario with information sharing, however the speedup depends on how well the agents' information can be used together. We demonstrate in this paper that state-space partitioning among agents can be realized by reward design without hard coded rules. The partitioning-associated reward directs agents to focus on different partitions and thus share information more efficiently. This approach has two advantages: (1) agents' actions are not diminished and remain relatively independent from one another; (2) it can be used to accelerate learning in both structured state domains (where partitions can be pre-determined) and arbitrarily-structured state domains (where partitions may be developed dynamically by agent teams as they explore the environment). Finally, we validate the method's efficacy by comparing it to previous related work in a simplified soccer domain.","PeriodicalId":6533,"journal":{"name":"2018 17th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"55 1","pages":"293-298"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76646298","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}
