Multiple Instance Learning using Bag Distribution Parameters
No full textIn pattern recognition and data analysis, objects or events are often represented by a feature vector with a fixed length. For some applications this is a severe limitation, and extensions have been proposed. One approach is Multiple-Instance Learning (MIL). Here, objects are represented by a collection of feature vectors (called a bag) and a bag is labeled positive, when at least one feature vector is member of a concept. In some situations it is not suitable to assume the presence of a concept, and the distribution of all the feature vectors in a bag is required to classify the bag. In this paper we propose a simple bag classification scheme using the parameters of the fitted distributions. Experiments show sometimes surprisingly good performances with respect to other state-of-the-art approaches.Intelligent SystemsElectrical Engineering, Mathematics and Computer Scienc

On M-Type Bag Structures
No full textIn this paper, the author introduces a structure called M-type bag structure which can be defined on a non-empty set associated with an indiscernibilty relation. It can be observed that an M-type bag structure represents a bag if the indiscernibility relation be defined in such a way that any two elements of the set are indiscernible under a given set of criteria that considers the values of some predefined attribute set. This paper further studies some algebraic properties of M-type bag structures
Mixed Bag
No full textThis lyric essay explores the relationship of environmental grief to grief triggered by the pandemic, political polarization, misogyny, and aging. As the author examines the impact of single-use plastic bags before and during COVID, she reflects on the plastic bag scene in the film American Beauty, and she grapples with her mother’s transition to assisted living. Also on the author’s mind are Katy Perry’s song “Firework,” the two most recent presidential elections, Ursula K. Le Guin’s “Carrier Bag Theory of Fiction,” and the impossibility of grasping the devastation caused by plastic pollution and COVID. The author hopes her essay offers company to others like herself who struggle with grief and who wonder how we can move forward
What’s in the Bag?
No full textThe Ross-Littlewood paradox describes a process of repeatedly adding and then removing chips from a bag. During the process, the size of the bag grows at each step; but at the end of the process, the bag is mysteriously found to be empty. This paper explores some new questions about which sets of chips could remain in the bag at the end of the process as well as some stochastic question not pursued in Ross\u27 work. The results presented in this paper were all proven by undergraduate students at the author\u27s institution as the students learned to work with quantifiers, uncountable sets, perfect subsets of the real line, probability, recurrence relations, and measure theory for the first time

No full textTowards spill-free in-bag morcellation: a health failure mode and effects analysis
No full textBackground: To assess potential risks of new surgical procedures and devices before their introduction into daily practice, a prospective risk inventory (PRI) is a required step. This study assesses the applicability of the Health Failure Mode and Effects Analysis (HFMEA) as part of a PRI of new technology in minimally invasive gynecologic surgery. Methods: A reference case was defined of a patient with presumed benign leiomyoma undergoing a laparoscopic hysterectomy or myomectomy including in-bag power morcellation; however, pathology defined a stage I uterine leiomyosarcoma. Using in-bag morcellation as a template, a HFMEA was performed. All steps of the in-bag morcellation technique were identified. Next, the possible hazards of these steps were explored and possible measures to control these hazards were discussed. Results: Five main steps of the morcellation process were identified. For retrieval bags without openings to accommodate instruments inside the bag, 120 risks were identified. Of these risks, 67 should be eliminated. For containment bags with openings 131 risks were identified of which 68 should be eliminated. Of the 10 causes most at risk to cause spillage, two can be eliminated by using appropriate bag materials. Myomectomy appears to be more at risk for residual tissue spillage compared to total hysterectomy. Conclusion: The HFMEA has provided important new insights regarding potential weaknesses of the in-bag morcellation technique, particularly with respect to hazardous steps in the morcellation process as well as requirements that bags should meet. As such, this study has shown HFMEA to be a valuable method that identifies and quantifies potential hazards of new technology.Medical Instruments & Bio-Inspired Technolog
Low-energy pion scattering in the cloudy-bag model
No full textBy applying a unitary transformation to the Lagrangian density of the cloudy-bag model, the author obtains a generalisation of the Weinberg effective Lagrangian for pion-nucleon scattering. The new Lagrangian incorporates the Weinberg-Tomozawa result for s-wave pion scattering from any hadronic bag in a very simple but elegant fashion.A W Thoma
On IC-Bag Based Systems
No full textIn this paper, we discuss the notion of IC-Bags as introduced by the author and some issues related to the systems development techniques associated with different phases Of IC-Bag based systems. We consider the situations where the hesitation factor associated with’ the count function is able to play a crucial role in defining the knowledge-base and the requirement specifications
Study on consumption value of luxury-bag consumption pattern
No full textThe issue of consumption pattern of luxury-bag has been concerned for a long time. The early researches of consumption pattern of luxury-bag, scholars studied on single consumption pattern of luxury-bag, it means, there is no research of many consumption patterns of luxury-bag in one time. So the author wants to compare the different consumption patterns of luxury-bag in consumption value, expecting that understanding the influencing factors between different consumers of purchasing patterns.
There are two purposes in the research, 1. Make the radar charts in different consumption patterns of luxury-bag, and then according to the results give the suggestions of marketing. 2.Compare the different consumption patterns of luxury-bag in a single consumption
value. By collecting and analyzing questionnaires, the results are that consumers with different patterns have different consumption value; people who purchase new luxury-bag have similar consumption value to people who purchase second-hand luxury-bag; people who purchase counterfeits pay much attention to social value; people who rent the luxury-bag pay much attention to condition value
