It takes countless hours of manual labour to achieve an aesthetically pleasing font one frequently encounters in digital media. Inter-letter spacing defines the texture and the feel of a typeface and when done accurately yields an aesthetically balanced and an appealing typeface. Nevertheless, setting spacing in a typeface is a tedious and a time consuming task. Hence this paper presents an exploratory study investigating the potential of Neural Networks (NN) to fully automate the typeface spacing process. Even though the NN models investigated in this study yielded up to an accuracy of 47% when compared with typefaces spaced by the type designers, the visual differences were subtle. Thus, we conclude that neural models can indeed be used to model the typeface spacing problem. As one of the first attempts to apply neural models in this particular problem domain, this study lays the foundation to future research and studies.","PeriodicalId":6636,"journal":{"name":"2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"16 1","pages":"769-773"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81505453","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}

A Thoracolumbosacral orthosis (TLSO) is a type of brace used to control the lateral curvature of the spine in scoliosis. It is a nonsurgical treatment with the goal of preventing curve progression in patients with idiopathic scoliosis. To successfully monitor compliance with brace treatment, we designed and developed a wearable multi-modal sensor solution is embedded into the patient’s brace. The custom designed hardware consists of a sensor board, a force sensor, an accelerometer and a gyroscope. The force sensor collects the force being exerted on the patient’s back, while the accelerometer and gyroscope generate cues to determine the patient’s activities and lifestyle. In this paper, we propose a novel data-mining method to identify patient activities and evaluate the effectiveness of the brace treatment pervasively based on fusion of continuous force and inertial motion recordings. Our aim is to design a context-aware remote monitoring system for ubiquitous evaluation and enhancement of brace treatment compliance of adolescent idiopathic scoliosis patients. We investigated experimental scenario in which, the patient performs a series of pre-defined activities at home during day long segments of brace wear, during pervasive sensor data recordings. The experimental results demonstrated that we achieved an overall accuracy of a 100% for semi-supervised activity detection. The level of tightness of brace-fit reduced gradually over a period of 4 weeks by 33%.","PeriodicalId":6636,"journal":{"name":"2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"76 1","pages":"580-585"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91261523","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}

Such variations are suppressed using feature extraction and Machine Learning (ML) techniques for improving the performance, but also reduce the adversary’s effort in breaking the system (security strength) using forged data. Typically for BAS design, performance and security strength are evaluated in isolation using experimental analysis. This research provides an analytical approach to evaluate the BAS performance and strength, and their trade-off, by modeling the biometric data, and studying the effect of feature extraction and ML configurations on processing the data.

The patient waiting experience remains one of the most vexing challenges facing healthcare. At our comprehensive cancer centre, waiting periods that arise throughout a patient’s course of treatment are generally difficult for staff to predict and only rough estimates are typically provided based on personal experience. To the patient, waiting times feel long and are seemingly unpredictable. Delays for treatment at our centre depend on the durations of preceding patients scheduled in the queue. To that end, we have incorporated the treatment records of all previously-treated patients into a machine learning framework in order to predict treatment durations to infer an overall waiting time. We found that the Random Forest Regression model provides the best predictions for daily fractionated radiotherapy treatment durations. Using this model, we achieved a median residual (actual minus predicted duration) of 0.25 minutes and a standard deviation residual of 6.1 minutes to retrospective treatment data. Waiting times are derived by summing the predicted durations. The main features that generated the best fit model (from most to least significant) are: Allocated appointment time, radiotherapy fraction number, median past duration of treatments, the number of treatment fields, and previous treatment duration.","PeriodicalId":6636,"journal":{"name":"2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"51 1","pages":"1024-1029"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72829418","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}

For the modeling, the component based modeling and the state-oriented modeling approaches have been integrated. First the track components and the control component are identified. The interaction of identified components, satisfying the safety requirements, is also defined in the high level architecture. Finally, state-oriented modeling approach has been adopted to design the detailed model of crossing region. Further, this paper uses the coverability tree to verify the specifications of crossing regions. By taking the crossing point as center, a circular region is introduced for safety purpose.

However, robust, interpretable machine learning tools are lacking, threatening extraction of scientific insight and discovery. Nonnegative Matrix Factorization (NMF) algorithms decompose an m × n nonnegative data matrix A into a k × n basis matrix H and an m × k weight matrix W, such that A ≈ WH, where k is the desired rank. In this paper, we present a novel two stage algorithm, UoI-NMF_cluster for NMF, which is based on three innovations: (i) completely separate bases learning from weight estimation, (ii) learn bases by clustering NMF results across bootstrap resamples of the data, and (iii) use the recently introduced Union of Intersections (UoI) framework to estimate ultra-sparse weights that maximize data reconstruction accuracy. We deploy our algorithm on various synthetic and scientific data to illustrate its performance, with a focus on neuroscience data. Compared to other NMF algorithms, UoI-NMF_cluster yields: a) more accurate parts-based decompositions of noisy data, b) a sparse and accurate weight matrix, and c) high accuracy reconstructions of the de-noised data. Together, these improvements enhance the performance and interpretability of NMF application to noisy data, and suggest similar approaches may benefit other matrix decomposition algorithms.","PeriodicalId":6636,"journal":{"name":"2017 16th IEEE International Conference on Machine Learning and Applications (ICMLA)","volume":"6 1","pages":"241-248"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82272011","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 paper, we analyze blood glucose-level sensors and propose a machine learning algorithm that detects intentional and inadvertent data modification intrusions for this type of sensors. The proposed algorithm uses Otsu’s Thresholding Method and other statistical measures to create features that estimate boundaries, averages, deviations and patterns of sensor data.
