Intracranial Hemorrhage is a common brain injury that leads to a high mortality rate without prompt recognition. To address these issues, computer-aid diagnosis tools are rapidly being developed along with neural-network-based techniques to provide fast, reliable analysis and achieve accurate diagnosis decisions based on medical images. One of the most interesting applications in computer-aid diagnosis is Image Registration due to its practical features in clinical diagnosis and treatment planning. In this study, we present the non-rigid image registration for the 3D Computed Tomography image dataset of the Intracranial Hemorrhage Brain. By utilizing the affine transformation and a neural network model, we aim to predict the deformation vector field, map the real-world-collected dataset to the reference space and overcome the shifting data problem between the data analysis experiment on standard and real-world medical image analysis. Our test results gave that good registration performance is obtained in a very short time by using a neural network model, and the affine transformation significantly improves the real-world image registration. In addition, according to the distance from the hematoma area change ratio to the brain area change ratio, the characteristics of the major structure are determined to be preserved.

Predicting Wearing-Off of Parkinson's Disease Patients Using a Wrist-Worn Fitness Tracker and a Smartphone: A Case Study Reviewed International journal

John Noel Victorino, Yuko Shibata, Sozo Inoue, Tom Shibata

Applied Sciences, MDPI 11 ( 16 ) 2 - 2 2021.08

Language：English Publishing type：Research paper (scientific journal)

Parkinson's disease (PD) patients experience varying symptoms related to their illness. Therefore, each patient needs a tailored treatment program from their doctors. One approach is the use of anti-PD medicines. However, a “wearing-off" phenomenon occurs when these medicines lose their effect. As a result, patients start to experience the symptoms again until their next medicine intake. In the long term, the duration of “wearing-off" begins to shorten. Thus, patients and doctors have to work together to manage PD symptoms effectively. This study aims to develop a prediction model that can determine the “wearing-off" of anti-PD medicine. We used fitness tracker data and self-reported symptoms from a smartphone application in a real-world environment. Two participants wore the fitness tracker for a month while reporting any symptoms using the Wearing-Off Questionnaire (WoQ-9) on a smartphone application. Then, we processed and combined the datasets for each participant's models. Our analysis produced prediction models for each participant. The average balanced accuracy with the best hyperparameters was at 70.071.7% for participant 1 and 76.176.9% for participant 2, suggesting that our approach would be helpful to manage the “wearing-off" of anti-PD medicine, motor fluctuations of PD patients, and customized treatment for PD patients.

Nattaya Mairittha, Tittaya Mairittha, Sozo Inoue

Proc. of ACM on Interactive, Mobile, Wearable and Ubiquitous Technologies, Article 142, 5 ( 0 ) 3 - 2 2021.03

Language：English Publishing type：Research paper (scientific journal)

In this study, we propose novel gamified active learning and inaccuracy detection for crowdsourced data labeling for an activity recognition system using mobile sensing (CrowdAct). First, we exploit active learning to address the lack of accurate information. Second, we present the integration of gamification into active learning to overcome the lack of motivation and sustained engagement. Finally, we introduce an inaccuracy detection algorithm to minimize inaccurate data. To demonstrate the capability and feasibility of the proposed model in realistic settings, we developed and deployed the CrowdAct system to a crowdsourcing platform. For our experimental setup, we recruited 120 diverse workers. Additionally, we gathered 6,549 activity labels from 19 activity classes by using smartphone sensors and user engagement information. We empirically evaluated the quality of CrowdAct by comparing it with a baseline using techniques such as machine learning and descriptive and inferential statistics. Our results indicate that CrowdAct was effective in improving activity accuracy recognition, increasing worker engagement, and reducing inaccurate data in crowdsourced data labeling. Based on our findings, we highlight critical and promising future research directions regarding the design of efficient activity data collection with crowdsourcing.

Elderly person are increasing all over the world. Smart nursing facilities
are required to support them for their good health.Especially in Japan, it is essential to
have automated nursing facilities center to support the relentlessly increasing elderly
person all over the country.As long as elderly people are increasing, the demand for
nursing care services are also increasing day by day.There is a shortage of nurse
to support this vast elderly people.In order to resolve the shortage of nurse, it is
important to reduce the work load for nurse.There are some research to simplify the
care recording process.The main approach is activity recognition or the development
of new apps. However, we aimed for automatic generation of the care records of near
future. So in this paper, we evaluate the accuracy of the automatic generation of
care records using care record data from real nursing facility to simplify the task of
making care records.We made two machine learning models to estimate the "target
patient" and the "recorded value" of care records.And we evaluated the classification
result from the data collected by the care record app.We used two months of data we
collected from Japanese nursing facility for the evaluation.We can achieve, average
F1-score of 'target patient' estimation is 74% and the average F1-score of 'detail of

Language：English Publishing type：Research paper (scientific journal)

One of the biggest challenges of activity data collection is the need to rely on users and keep them engaged to continually provide labels. Recent breakthroughs in mobile platforms have proven effective in bringing deep neural networks powered intelligence into mobile devices. This study proposes a novel on-device personalization for data labeling for an activity recognition system using mobile sensing. The key idea behind this system is that estimated activities personalized for a specific individual user can be used as feedback to motivate user contribution and improve data labeling quality. First, we exploited fine-tuning using a Deep Recurrent Neural Network to address the lack of sufficient training data and minimize the need for training deep learning on mobile devices from scratch. Second, we utilized a model pruning technique to reduce the computation cost of on-device personalization without affecting the accuracy. Finally, we built a robust activity data labeling system by integrating the two techniques outlined above, allowing the mobile application to create a personalized experience for the user. To demonstrate the proposed model's capability and feasibility, we developed and deployed the proposed system to realistic settings. For our experimental setup, we gathered more than 16,800 activity windows from 12 activity classes using smartphone sensors. We empirically evaluated the proposed quality by comparing it with a baseline using machine learning. Our results indicate that the proposed system effectively improved activity accuracy recognition for individual users and reduced cost and latency for inference for mobile devices. Based on our findings, we highlight critical and promising future research directions regarding the design of efficient activity data collection with on-device personalization.

Technology can help and provide support to people with dementia to ensure their safety during daily
activities. In this paper, we summarize information about activity recognition for people living with
dementia. This paper aims to understand the uses and types of applications, the types of sensors/systems,
methods, and data used within the scope of human activity recognition to monitor, detect symptoms, or
help people with dementia. To this end, 447 abstracts were collected from a Scopus database, which
yielded 127 relevant papers and 102 papers that were considered in detail based on the four categories of
assessment (application, system/sensors, methods, and data). This paper shows the trend that smart
environment technology is most widely used for monitoring people with dementia, wherein machine
learning techniques as a method for activity recognition to achieve the results of testing or implementing
the system. We conclude that combining sensor devices and the addition of smartphone devices in one
system is suitable for implementation because it can be used as an identity such that it distinguishes the
object under study with other objects. During the monitoring process, prevention can be achieved
simultaneously by adding a warning alarm in the smartphone when people with dementia perform
abnormal activities, and the results need to be further analyzed to get the best pattern of activities for
people with dementia. Next, the type of application that was initially designed for monitoring can be
developed into an assistant for people with dementia.

In data collection of the human physiological and psychological conditions
for mental healthcare (e.g., work engagement), measurement methods using
environment-installed sensors and questionnaire surveys have been often
used. However, these approaches are not practical in continuous data
collection, due to the large burden for people. Recently, in association
with advancing sensing technology with IoTs, sensing by small sensors and
wearable devices has become possible easily. In this paper, we
aim to establish a simple and general sensing method based on a mobile
application for measuring physiological and psychological state of office
workers and environmental state. Through the experiment for 2-3 weeks
involving 60 office workers of four Japanese companies by using our
application, we succeeded to create a dataset of physiological,
environment, and mental state. This paper explains the developed mobile

Language：English Publishing type：Research paper (scientific journal)

The integration of digital voice assistants in nursing residences is becoming increasingly important to facilitate nursing productivity with documentation. A key idea behind this system is training natural language understanding (NLU) modules that enable the machine to classify the purpose of the user utterance (intent) and extract pieces of valuable information present in the utterance (entity). One of the main obstacles when creating robust NLU is the lack of sufficient labeled data, which generally relies on human labeling. This process is cost-intensive and time-consuming, particularly in the high-level nursing care domain, which requires abstract knowledge. In this paper, we propose an automatic dialogue labeling framework of NLU tasks, specifically for nursing record systems. First, we apply data augmentation techniques to create a collection of variant sample utterances. The individual evaluation result strongly shows a stratification rate, with regard to both fluency and accuracy in utterances. We also investigate the possibility of applying deep generative models for our augmented dataset. The preliminary character-based model based on long short-term memory (LSTM) obtains an accuracy of 90% and generates various reasonable texts with BLEU scores of 0.76. Secondly, we introduce an idea for intent and entity labeling by using feature embeddings and semantic similarity-based clustering. We also empirically evaluate different embedding methods for learning good representations that are most suitable to use with our data and clustering tasks. Experimental results show that fastText embeddings produce strong performances both for intent labeling and on entity labeling, which achieves an accuracy level of 0.79 and 0.78 f1-scores and 0.67 and 0.61 silhouette scores, respectively.

To understand the biology of health, and how molecular dysfunction leads to disease, knowledge of the human cell is essential. The protein is the core unit of the human body made from trillions of cells, forming the body's various tissues. These tissues come together to create human organs. It is essential to understand the Spatio-temporal distribution of proteins in cells and to investigate human RNA-sequencing for human genes characterization. For this, it requires a massive amount of annotated data. However, due to many considerations like the high cost of data sample collection, lack of data sample availability, and lawful clauses for patient privacy, the majority of medical data is out of reach for general public research. In this study, we propose a new dual deep generative method for synthesizing human cell protein images by using the Generative Adversarial Network technique. Specifically, for that, we pair original cell protein images with their respective Cell-protein-tree. These pairs are then used to learn the mapping from a binary cell protein to a new cell protein image. For this purpose, we use an image-to-image translation technique based on adversarial learning. The generated cell protein images are expected to preserve the structural and visual quality of the training images. Visual and quantitative analysis of the experimental results demonstrates that the synthesized data are preserving the desired quality while maintaining the different forms of original data. Contribution-We have proposed a new dual deep generative model for synthesizing cell protein data.

One of the most important aspects of professional athleticism and rehabilitation is muscle activation. Although sport tracking technologies are advancing
rapidly, existing technologies and devices for detecting muscle performance are still
out of common users' hands, due to their complexity, invasive nature and high cost.
However, sensor equipped devices are getting widely available, which opens the
door to alternative solutions using software. In this work we explore the possibility
of using accelerometer data for muscle performance in a weightlifting exercise. By
investigating a predefined common weightlifting exercise, we exploited a correlation between the acceleration and the lifted weights using a simple RBF prediction
method, in a real experiment where data obtained from three participants. The obtained results show that the weight could be predicted in acceptable accuracy for
each individual, based on acceleration data.

Characterizing Word Embeddings for Zero-Shot Sensor-Based Human Activity Recognition Reviewed International journal

Moe Matsuki, Paula Lago, Sozo Inoue

MDPI Sensors 19 ( 22 ) 1 - 26 2019.11

Language：English Publishing type：Research paper (scientific journal)

In this paper, we address Zero-shot learning for sensor activity recognition using word embeddings. The goal of Zero-shot learning is to estimate an unknown activity class (i.e., an activity that does not exist in a given training dataset) by learning to recognize components of activities expressed in semantic vectors. The existing zero-shot methods use mainly 2 kinds of representation as semantic vectors, attribute vector and embedding word vector. However, few zero-shot activity recognition methods based on embedding vector have been studied; especially for sensor-based activity recognition, no such studies exist, to the best of our knowledge. In this paper, we compare and thoroughly evaluate the Zero-shot method with different semantic vectors: (1) attribute vector, (2) embedding vector, and (3) expanded embedding vector and analyze their correlation to performance. Our results indicate that the performance of the three spaces is similar but the use of word embedding leads to a more efficient method, since this type of semantic vector can be generated automatically. Moreover, our suggested method achieved higher accuracy than attribute-vector methods, in cases when there exist similar information in both the given sensor data and in the semantic vector; the results of this study help select suitable classes and sensor data to build a training dataset.

介護施設紹介コールセンターの記録データをアンサンブル学習を用いて傾向分析や将来予測を行い，「コールセンター」「介護施設」「相談者と入居者」の三者にとって有用な知見を取得する．介護分野における問題に対して，現場のデータを分析し問題解決に有用な知見を得る研究は多くあるが，それらは入居後の問題解決に向けたデータ分析がほとんどである．本研究では，介護施設入居前の分析も重要と考え，入居前の相談を受け付けるコールセンターの記録データを分析する．分析方法は，アンサンブル学習を用いて，説明変数の属性値を2値化し，属性の重要度と目的変数に対する正負の相関を同時に可視化した．記録データは，相談者1名に対し1行，「性別」や「介護度」のような属性を列とした，7,685行106列の行列データである．分析の結果，記録に欠損が多い人は成約に行かないことや，交通手段が見学に行くかどうかの重要な要因であること，「見学するかどうか」は機械学習による精度が96．8%であること，入居決定の決め手は「介護サービス」ではなく，「きれいさ」や「印象」，「距離」であることなど，10件ほどの知見を取得した．

本論文は，複数介護施設における事故報告書を使用して，テキストマイニングおよび機械学習により事故の起こりうる状況を分析した結果について述べる．

まず，テキストデータと多変量データが混合したデータに対して，テキストマイニングおよびランダムフォレスト法を組み合わせて，事故の結果に対して影響する要因を抽出する方法を提案した．

まずテキストデータについては分かち書きを行い単語文書行列を構成し，単語についてクラスタリングを行った結果を元の多変量データと結合し，事故の結果として目的変数を設定しランダムフォレスト法￥new{を2段階で適用しながら重要な単語クラスタ及び重要な単語と属性}を抽出し，決定木によって可視化するという手法である．

この手法を，介護施設から得られた5,189件の事故事例について適用したところ，

原因不明のあざの発見のされ方や，転倒・ずり落ちから打撲につながるような行動，誤嚥につながる状況，無断外出につながる行動といった幾つかのパターンを抽出できた．

本研究では,看護師の業務分析のため,33 日間に渡り看護師の業務行動データを収集する実験を行い,業務中の看護師の行動の激しさおよび,業務時間に影響を与える要因について分析を行った.データ収集実験では,38 人の看護師を被験者に設定して,装着型の小型センサ端末を装着した状態で業務を行ってもらい,加速度データおよび看護師間の対面情報,看護師業務情報を収集した.また,赤外線を用いた情報通信機器によって看護師の位置情報も同時に収集した.本稿では,看護師業務中の行動の激しさを目的変数,看護師業務毎の回数,対面回数,場所毎の訪問回数などを説明変数に設定して,決定木 (回帰木) を用いた要因分析を行った.その結果,他の看護師との対面回数が多く,病室に何度も訪れている看護師や,リハビリ介助業務や行動介助業務などの患者の介助に関わる業務を行う看護師ほど,行動の激しさが大きくなるという結果を得た.また,業務時間が業務効率に直結していると考え,各業務時間の長さに影響を及ぼす要因について回帰分析によって調べた.その後,単回帰分析により有意水準 5%で有意となった説明変数の業務だけを抽出し,その業務に対して決定木を用いた要因分析を行った.単回帰分析の結果, 14 の業務において有意な結果が得られた.また,決定木による要因分析の結果,ほとんどの業務において他の看護師との対面人数が業務時間に影響を与えていることがわかった.また,食事介助業務中に特定の場所に訪れる看護師ほど業務時間が長くなるという結果を得た.

Language：Japanese Publishing type：Research paper (bulletin of university, research institution)

平成20年度，九州大学附属図書館において，機関リポジトリを永続的に運用するために必要な人材育成を目的とした講習会が開催された．これは，国立情報学研究所の委託事業によるもので，事業連携大学をはじめとして，北は北海道，南は沖縄からの参加者もあり，学内外から毎回約20名の受講者が参加した．受講者は，html言語やPHP言語等を題材にシステムに関する概念やwebシステム開発の基礎知識と技術を学んだ．全3回，各回2日間(約10時間)，講義を受け，演習・発表を行い，次回に向けての宿題も課せられた．また，個人のスキルアップのみでなく，講習会後は受講者が主軸となり，講習会の内容を波及させていったことが今回の講習会の特徴である．
