In this paper, a novel efficient algorithm is presented for locating and tracking object parts in low resolution videos using Lowe's SIFT keypoints with a nearest neighbor object detection approach. Our interest lies in using this information as one step in the process of automatically programming service, household, or personal robots to perform the skills that are being taught in easily obtainable instructional videos. In the reported experiments, the system looked for 14 parts of inanimate and animate objects in 40 (...) natural outdoor scenes. The scenes were frames from a low-resolution instructional video on cleaning golf clubs containing 2,405 frames of 180 by 240 pixels. The system was trained using 39 frames that were half-way between the test frames. Despite the low resolution quality of the instructional video and occluded training samples, the system achieved a recall of 49% with a precision of 71% and an F1 of 0.58, which is better than that achieved by less demanding applications. In order to verify that the reported results were not dependent on the specific video, the proposed technique was applied to another video and the results are reported. (shrink)

The Institute on Religion in the Age of Science (IRAS) asked Ted Peters, an eminent theologian and bioethicist who was at the forefront of the cloning and stem cell debates in the past few decades, and myself, a molecular biologist, to invite scholars from various fields to brainstorm the religious and ethical implications of the CRISPR revolution. We invited keynote speakers, whose talks will be covered here, as well as other speakers and poster presentations. The conference also hosted question and (...) answer sessions, chaplain sessions, and discussions throughout the week at the beautiful Star Island in the summer of 2019. The purpose of this paper is to highlight and sample the discussions and presentations from that conference. I will organize them into three broad topics: CRISPR in science, ethics, and religion. For readers unfamiliar with CRISPR technology, this overview can also serve as an introduction to the field, and a stepping stone for future ideas for CRISPR discussions. (shrink)

Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) has been the buzzword for genome editing in the past few years, especially with the birth of Lulu and Nana, twin girls who were genetically edited using the CRISPR/Cas system. To discuss this, a group of scientists, theologians, and ethicists gathered at the 2019 Institute on Religion in the Age of Science (IRAS) conference to discuss the implications of CRISPR gene editing. It became quickly apparent through our discussions that this CRISPR revolution will (...) impact not only human medicine, but any application that involves DNA in every organism from bacteria to plants and animals. Moreover, there are multiple stakeholders in this technology—not only the scientific community, but also the business, legal, and religious communities, to name a few. As a scientist myself, I am providing a brief overview of the scientific hopes and concerns about this powerful technology. (shrink)

In a distributed multi-agent system, an idle agent may be available to assist other agents in the system. An agent architecture called intent recognition is proposed in this article to accomplish this with minimal communication. To assist other agents in the system, an agent performing recognition observes the tasks other agents are performing. Unlike the much-studied field of plan recognition, the overall intent of an agent is recognized instead of a specific plan. The observing agent may use capabilities that it (...) has not observed. In this study, the key research question is: What are intent-recognition systems and how can these be used to have agents autonomously assist each other effectively and efficiently? A conceptual framework is proposed to address this question. An implementation of the conceptual framework is tested and evaluated. A set of metrics, including task time and number of communications, is used to compare the performance of plan recognition and intent recognition. This research shows that under certain conditions, an intent-recognition system is more efficient than a plan recognition system. (shrink)

This article presents the design and development of a genetic algorithm to generate long-range transmit codes with low autocorrelation side lobes for radar to minimize target profile estimation error. The GA described in this work has a parallel processing design and has been used to generate codes with multiple constellations for various code lengths with low estimated error of a radar target profile.

To assist in the evaluation process when determining architectures for new robots and intelligent systems equipped with artificial emotions, it is beneficial to understand the systems that have been built previously. Other surveys have classified these systems on the basis of their technological features. In this survey paper, we present a classification system based on a model similar to that used in psychology and philosophy for theories of emotion. This makes possible a connection to thousands of years of discourse on (...) the topic of emotion. Five theories of emotion are described based on an emotion theory model proposed by Power and Dalgleish. The paper provides classifications using a model of 10 new questions, for 14 major research projects that describe implementations or designs for systems that use artificial emotions for either robotics or general artificial intelligence. We also analyze the trends in the usage of various theories and complexity changes over time. (shrink)

Human skin detection is an essential phase in face detection and face recognition when using color images. Skin detection is very challenging because of the differences in illumination, differences in photos taken using an assortment of cameras with their own characteristics, range of skin colors due to different ethnicities, and other variations. Numerous methods have been used for human skin color detection, including the Gaussian model, rule-based methods, and artificial neural networks. In this article, we introduce a novel technique of (...) using the neural network to enhance the capabilities of skin detection. Several different entities were used as inputs of a neural network, and the pros and cons of different color spaces are discussed. Also, a vector was used as the input to the neural network that contains information from three different color spaces. The comparison of the proposed technique with existing methods in this domain illustrates the effectiveness and accuracy of the proposed approach. Tests were done on two databases, and the results show that the neural network has better precision and accuracy rate, as well as comparable recall and specificity, compared with other methods.

Amblyopia, or lazy eye, is a neurological vision disorder that studies have shown to affect two to five percent of the population. Current methods of treatment produce the best visual outcome, if the condition is identified early in the patient's life. Several early screening procedures are aimed at finding the condition while the patient is a child, including an automated vision screening system. This paper aims to use artificial intelligence techniques to automatically identify children who are at risk for developing (...) the amblyopic condition and should therefore be referred to a specialist, i.e., pediatric ophthalmologist. Three techniques, namely, decision tree learning, random forest, and artificial neural network, are studied in this paper in terms of their effectiveness, using metrics of sensitivity, specificity, and accuracy. The features used by the techniques are extracted from images of patient eyes and are based on the color information. The efficacy of pixel color data is investigated with respect to the measurement of the rate of change of the color in the iris and pupil, i.e., color slope features. A 10-fold stratified cross validation procedure is used to compare the effectiveness of the three AI techniques in this medical application domain. (shrink)

Mula sa iisang lahi ang Pilipinas at Malaysia sang-ayon sa pag-aaral na may kinalaman sa paksaing Austronesyo. May mahabang kasaysayan ng ugnayan ang dalawang bansang ito, di lámang sa ekonomikong aspekto, kundi lalo’t higit sa kultural na batayan, at isa na rito ang paggamit ng mga simbolo sa pagbabatik/pagtatatu na nakaugat pa sa relihiyon ng pag-aanito sa mundong Austronesyo. Bagamat naging parehong kolonya ang dalawang bansa ng mga Kanluranin na nagpalawak di lámang ng kapangyarihan kundi maging ng merkado, hindi tuluyang (...) naalis/nakalimutan ang kalinangang nakaugat sa mga bansang ito. Sa kasalukuyan, nagpapatúloy pa rin ang iláng tradisyonal na pang-araw-araw na búhay ng ilang bahagi ng mga bansang ito gaya ng pagbabatik. Nariyan pa rin ang pagpupukpok o tapping process sa pagbabatik na sa kasalukuyan ay dinarayo pa sa kabundukan ng Cordillera ng mga tagasiyudad upang makapagpatatu kay Whang Od. Gayundin, mayroon pa ring kahalintulad na ganitong paraan ng pagbabatik sa Malaysia, sa kaso halimbawa ng mga Iban, Kayan at Dayak. Hindi kataka-taka sa kasalukuyan na kahit nariyan pa rin ang tradisyonal na paraan ng pagbabatik, naghahalinhinan ang tradisyonal at modernong pagbabatik sa mga bansang ito na ang pinakanag-uugnay ay ang mga simbolismong nakaugat sa kanilang malalim na kasaysayan.

In this book, the contributors examine how various religious traditions engage with transhumanism and its vision for the future.

Les Prolegomenes a la Philosophie de Platon sont un manuel d'ecole neoplatonicien. Il s'inspire d'un modele dont Proclus a du etre l'auteur, mais l'origine de ce texte est presque surement alexandrine et doit dater de la premiere moitie du Vle siecle. Cette oeuvre est essentielle pour comprendre comment etait diffuse l'enseignement platonicien, et pour mieux saisir le mouvement des idees de l'Antiquite finissante. Dans une importante introduction, L. O. Westerink a retrace l'histoire de l'ecole d'Alexandrie et celle du genre litteraire (...) de ces introductions a Platon et a Aristote. (shrink)

Purpose. To examine the existential anthropology of G. Marcel and E. Minkowski, in order to demonstrate the necessity of distinguishing the universal-spiritual, as human in human being, apart from the individual-existential in him, and to reveal the hierarchical correlation of biosocial, existential and spiritual spheres in personality. Theoretical basis. Within existential philosophy the author differentiates two separate traditions and proceeds from the insufficiency of the distinction of existential sphere, proposed by phenomenological tradition, showing the necessity of its correlation with the (...) spiritual sphere as a sphere of humanity, proposed by non-phenomenological tradition of G. Marcel and E. Minkowski. Originality. The author presents the anthropological conception of G. Marcel and E. Minkowski, in which human personality is understood as unity of individual-existential and universal-spiritual, which requires a special trans-empirical field of culture, which contains senses, images and symbols of humanity. Also, the author presents the recent developments of existential thinkers in distinguishing existential and spiritual dimensions, both not reducible to the physical and social dimensions. Conclusions. In both existential traditions, the specifically human was founded as a trans-biological and trans-social phenomenon, which appears as indefinable and non-predetermined. But in first tradition, humanity is understood as an existence, as a unique individuality, "project", variant of humanity, equivalent to other variants, and universal is understood as a community of human condition in the world. While in the second tradition, the universal is understood as spiritual. Thus, horizontal level of our private existence, as the process of movement from birth to death, is supplemented by vertical of human, universal ideals and images. Humanity appears as a task, on the way to which human being transcends beyond the limits of his individual "self" to the "super-individual", through inclusion into spiritual community, into universal culture.
