For an online delivery platform, accurate physical locations of merchants are essential for delivery scheduling. It is challenging to maintain tens of thousands of merchant locations accurately because of potential errors introduced by merchants for profits (e.g., potential fraud). In practice, a platform periodically sends a dedicated crew to survey limited locations due to high workforce costs, leaving many potential location errors. In this paper, we design and implement ALWAES, a system that automatically identifies and corrects location errors based on fundamental tradeoffs of five measurement strategies from manual, physical, and virtual data collection infrastructures for online delivery platforms. ALWAES explores delivery data already collected by platform infrastructures to measure the travel time of couriers between merchants and verify all merchants' locations by cross-validation automatically. We explore tradeoffs between performance and cost of different measurement approaches. By comparing with the manually-collected ground truth, the experimental results show that ALWAES outperforms three other baselines by 32.2%, 41.8%, and 47.2%, respectively. More importantly, ALWAES saves 3,846 hours of the delivery time of 35,005 orders in a month and finds new erroneous locations that initially were not in the ground truth but are verified by our field study later, accounting for 3% of all merchants with erroneous locations.

Wasl al-Fiqh bi al-Hadith integrates jurisprudence and hadith so that it enables fiqh experts to rely on hadith in formulating their rulings while hadith experts can derive a more accurate interpretation. Among others, this concept is applied at Aceh traditional dayah as the oldest Islamic educational institution in the Malay Archipelago which Acehness put their respect as the reference in Islamic rulings and teaching. This field study took place at Dayah Mudi Mesra, Samalanga, Aceh, due to its long-established reputation and great influence among Acehnese. The study aims to shed some light on the concept of wasl al-Fiqh bi al-Hadith according to some Islamic scholars, analyze the concept as perceived by the traditional Dayah of Aceh, and portray the polemic on Friday prayer ritual as prescribed by the traditional Dayah. The study employs qualitative data collection instruments consisting of library data, interviews, observations, and documentation. Inductive, deductive, and comparative methods were used for data analysis. The study found that implementation of this concept at the Dayah has been synonymous with the exclusive adoption of Shafi’i school as it heavily relies on several Shafi’i books or opinions of Shafi’i scholars as primary references.(Wasl al-Fiqh bi al-Hadith memadukan kajian fiqh dan hadis sehingga ahli fiqh dapat berpedoman kepada hadis dalam merumuskan aturan-aturan hukum sementara ahli hadis dapat mengetahui makna sebuah hadis dengan lebih akurat. Konsep ini salah satunya diterapkan di Dayah Tradisional Aceh, sebuah lembaga kajian Islam tertua di Kepulauan Melayu yang disegani dan menjadi rujukan dalam hal aturan serta ajaran Islam di masyarakat setempat. Kajian ini merupakan studi lapangan yang bertempat di Dayah Mudi Mesra Samalanga Aceh karena pengaruhnya yang sudah lama dan berakar kuat bagi masyarakat Aceh. Ia bertujuan mendalami konsep wasl al-fiqh bi al-hadith menurut para cendekiawan Muslim, mengkaji pemahaman akan konsep wasl al-fiqh bi al-hadith di kalangan Dayah tersebut dan memotret polemik soal pelaksanaan Salat Jumat di dalamnya. Kajian ini merupakan studi kualitatif dengan pengumpulan data secara pustaka, wawancara, observasi, dan dokumentasi. Sementara itu, analisis data dilakukan secara induktif, deduktif, dan komparatif. Hasil penelitian ini menunjukkan bahwa implementasi konsep tersebut sebenarnya tidak lebih dari adopsi eksklusif terhadap madzhab Syafi’i karena ketergantungan yang demikian kuat pada buku-buku madzhab Syafi’i serta pandangan ulama-ulama Syafi’iyyah sebagai referensi utama)

  Penelitian ini merupakan studi lapangan yang menjelaskan masalah pokok tentang budaya lipas pada masyarakat mandar majene ditinjau dari pendidikan islam. Tujuan dari penelitian ini Antara lain untuk mengetahui konsep lipas dalam masyarakat mandar majene, faktor dilakukannya lipas dan implikasi lipas dalam pendidikan islam. Metode yang digunakan dalam penelitian adalah metode pengumpulan dara yang terdiri dari observasi dan wawancara. Peneliti terjun langsung ke lapangan dan mewawancarai langsung orang-orang yang dianggap paham dan dapat dipercaya dalam masalah lipas di daerah Majene. Hasil yang diperoleh dalam penelitian ini adalah Budaya lipas masyarakat mandar majene ini muncul sebagai hukuman moral bagi anggota keluarga yang melanggar tradisi. Lipas pada masyarakat mandar majene dipengaruhi oleh beberapa faktor seperti: sipaindongang (kawin lari), Battang Bule (hamil diluar nikah), siala tania sambona (menikah dengan bukan sederajatnya), siala to poppoang (kawin dengan orang yang punya penyakit poppo’), siala to tandissang rumbu apinna (menikah dengan orang yang tidak dikenal asal usulnya). Lipas merupakan sanksi moral yang diberikan kepada anggota keluarga yang melakukan perbuatan tercela atau perbuatan yang bertentangan dengan tradisi dan jika dilihat dari pemahaman pendidikan Islam sebenarnya islam tidak pernah melarang budaya positif dalam kehidupan masyarakat. Justru Islam dapat melestarikan budaya melalui proses kehidupan yang dilandasi dengan nilai-nilai ajaran Alquran dan al-Hadis.   This research is a field study that explains the main problem of cockroach culture in the Mandar Majene community in terms of Islamic education. The purpose of this study, among others, to determine the concept of cockroach in human society, the factors of knowing cockroaches and the interaction of cockroaches in Islamic education. The method used in this research is data collection method which consists of observation and interviews. Researchers went directly to the field and directly interviewed people who were considered to be knowledgeable and trustworthy in the problem of cockroaches in the Majene area. The results obtained in this study are the cockroach culture of the Majene mandar community appears as a moral punishment for family members who violate traditions. Lipas in the Mandar Majene community is influenced by several factors such as: sipaindongang (elopement), Battang Bule (pregnant out of wedlock), siala tania sambona (married to someone who is not equal), siala to poppoang (married with someone who has Poppo'), unlucky to tandissang rumbu apinna (married to a person whose origin is unknown). Lipas is a moral sanction given to family members who commit disgraceful acts or actions that are contrary to tradition and when viewed from the understanding of Islamic education, it has never prohibited positive culture in people's lives. Islam can occur through a life process that is based on the values ​​of the teachings of the Quran and al-Hadith.

Background Model building is a crucial part of omics based biomedical research to transfer classifications and obtain insights into underlying mechanisms. Feature selection is often based on minimizing error between model predictions and given classification (maximizing accuracy). Human ratings/classifications, however, might be error prone, with discordance rates between experts of 5–15%. We therefore evaluate if a feature pre-filtering step might improve identification of features associated with true underlying groups. Methods Data was simulated for up to 100 samples and up to 10,000 features, 10% of which were associated with the ground truth comprising 2–10 normally distributed populations. Binary and semi-quantitative ratings with varying error probabilities were used as classification. For feature preselection standard cross-validation (V2) was compared to a novel heuristic (V1) applying univariate testing, multiplicity adjustment and cross-validation on switched dependent (classification) and independent (features) variables. Preselected features were used to train logistic regression/linear models (backward selection, AIC). Predictions were compared against the ground truth (ROC, multiclass-ROC). As use case, multiple feature selection/classification methods were benchmarked against the novel heuristic to identify prognostically different G-CIMP negative glioblastoma tumors from the TCGA-GBM 450 k methylation array data cohort, starting from a fuzzy umap based rough and erroneous separation. Results V1 yielded higher median AUC ranks for two true groups (ground truth), with smaller differences for true graduated differences (3–10 groups). Lower fractions of models were successfully fit with V1. Median AUCs for binary classification and two true groups were 0.91 (range: 0.54–1.00) for V1 (Benjamini-Hochberg) and 0.70 (0.28–1.00) for V2, 13% (n = 616) of V2 models showed AUCs < = 50% for 25 samples and 100 features. For larger numbers of features and samples, median AUCs were 0.75 (range 0.59–1.00) for V1 and 0.54 (range 0.32–0.75) for V2. In the TCGA-GBM data, modelBuildR allowed best prognostic separation of patients with highest median overall survival difference (7.51 months) followed a difference of 6.04 months for a random forest based method. Conclusions The proposed heuristic is beneficial for the retrieval of features associated with two true groups classified with errors. We provide the R package modelBuildR to simplify (comparative) evaluation/application of the proposed heuristic (http://github.com/mknoll/modelBuildR).

Researchers worldwide use remotely sensed imagery in their projects, in both the social and natural sciences. However, users often encounter difficulties working with satellite images and aerial photographs, as image interpretation requires specific experience and skills. The best way to acquire these skills is to go into the field, identify your location in an overhead image, observe the landscape, and find corresponding features in the overhead image. In many cases, personal observations could be substituted by using terrestrial photographs taken from the ground with conventional cameras. This chapter discusses the value of terrestrial photographs as a substitute for field observations, elaborates on issues of data collection, and presents results of experimental estimation of the effectiveness of the use of terrestrial ground truth photographs for interpretation of remotely sensed imagery. The chapter introduces the concept of GeoTruth – a web-based collaborative framework for collection, storing and distribution of ground truth terrestrial photographs and corresponding metadata.

Weak-label learning deals with the problem where each training example is associated with multiple ground-truth labels simultaneously but only partially provided. This circumstance is frequently encountered when the number of classes is very large or when there exists a large ambiguity between class labels, and significantly influences the performance of multi-label learning. In this paper, we propose LCForest, which is the first tree ensemble based deep learning method for weak-label learning. Rather than formulating the problem as a regularized framework, we employ the recently proposed cascade forest structure, which processes information layer-by-layer, and endow it with the ability of exploiting from weak-label data by a concise and highly efficient label complement structure. Specifically, in each layer, the label vector of each instance from testing-fold is modified with the predictions of random forests trained with the corresponding training-fold. Since the ground-truth label matrix is inaccessible, we can not estimate the performance via cross-validation directly. In order to control the growth of cascade forest, we adopt label frequency estimation and the complement flag mechanism. Experiments show that the proposed LCForest method compares favorably against the existing state-of-the-art multi-label and weak-label learning methods.

As research in smart homes and activity recognition is increasing, it is of ever increasing importance to have benchmarks systems and data upon which researchers can compare methods. While synthetic data can be useful for certain method developments, real data sets that are open and shared are equally as important. This paper presents the E-care@home system, its installation in a real home setting, and a series of data sets that were collected using the E-care@home system. Our first contribution, the E-care@home system, is a collection of software modules for data collection, labeling, and various reasoning tasks such as activity recognition, person counting, and configuration planning. It supports a heterogeneous set of sensors that can be extended easily and connects collected sensor data to higher-level Artificial Intelligence (AI) reasoning modules. Our second contribution is a series of open data sets which can be used to recognize activities of daily living. In addition to these data sets, we describe the technical infrastructure that we have developed to collect the data and the physical environment. Each data set is annotated with ground-truth information, making it relevant for researchers interested in benchmarking different algorithms for activity recognition.
