This paper aims to propose an improved learning algorithm for feature selection, termed as binary superior tracking artificial bee colony with dynamic Cauchy mutation. To enhance exploitation capacity, a binary learning strategy is proposed to enable each bee to learn from the superior individuals in each dimension. A dynamic Cauchy mutation is introduced to diversify the population distribution. Ten datasets from UCI repository are adopted as test problems, and the average results of cross-validation of BSTABC-DCM are compared with other seven (...) popular swarm intelligence metaheuristics. Experimental results demonstrate that BSTABC-DCM could obtain the optimal classification accuracy and select the best representative features for the UCI problems. (shrink)

Poverty alleviation by consumption is a powerful way to help the poor people get rid of poverty, which plays a significant role in China's rural revitalization. However, the achievement of poverty alleviation by consumption mostly depends on government procurement, and the enthusiasm of customers to participate is low, facing the severe challenge of poor sustainability. Helping the poor is the most common motivation for customers to buy poverty-alleviation agricultural products. However, as the negative events of poverty alleviation such as “tragic (...) marketing” constantly appear in news reports, customers' trust in sellers has been seriously damaged. The psychological protection system for fear of being cheated hinders customers' purchase intention. Therefore, we believed that trust is an important factor in enhancing customers' purchase intention of PAAP. Customers buy PAAP mainly through online channels, and institution-based trust is the most important way to generate trust in online channels. Thus, this study investigated the institutional mechanisms that affect customers' trust in the sellers of PAAP and discussed the influence of trust on the online purchase intention of PAAP. Data were obtained through a questionnaire survey and tested empirically. The results showed that the effectiveness of the user feedback mechanism, platform supervision mechanism, product traceability mechanism, and product certification mechanism can enhance customers' purchase intention by enhancing their trust. Individual trust tendency positively regulated the relationship between the effectiveness of institutional mechanisms and consumer trust. The conclusion can not only provide new theoretical guidance for the practice of poverty alleviation by consumption in China but also offer new ideas for the poverty alleviation undertakings in other countries.

For unmanned aerial vehicle, object detection at different scales is an important component for the visual recognition. Recent advances in convolutional neural networks have demonstrated that attention mechanism remarkably enhances multiscale representation of CNNs. However, most existing multiscale feature representation methods simply employ several attention blocks in the attention mechanism to adaptively recalibrate the feature response, which overlooks the context information at a multiscale level. To solve this problem, a multiscale feature filtering network is proposed in this paper for image (...) recognition system in the UAV. A novel building block, namely, multiscale feature filtering module, is proposed for ResNet-like backbones and it allows feature-selective learning for multiscale context information across multiparallel branches. These branches employ multiple atrous convolutions at different scales, respectively, and further adaptively generate channel-wise feature responses by emphasizing channel-wise dependencies. Experimental results on CIFAR100 and Tiny ImageNet datasets reflect that the MFFNet achieves very competitive results in comparison with previous baseline models. Further ablation experiments verify that the MFFNet can achieve consistent performance gains in image classification and object detection tasks. (shrink)

自己思考過後找到的答案，往往跟自己有關。 這個屬於自己的答案，當然比別人給的更特別，更好。__褚士瑩 褚士瑩師事法國哲學老師奧斯卡‧柏尼菲，從這一位「非典型」老師身上經歷了前所未有的思考練習與震撼教育。 世界上這麼多東西可以學，為什麼一定要學哲學？而且值得學的老師那麼多，為什麼偏偏是奧斯卡？ 褚士瑩形容奧斯卡是「搶走禮物的聖誕老人」，甚至因為幫忙安排諮商行程，竟然收到律師函，成為被告上法庭…… 但是褚士瑩卻在學習哲學思考的過程中，變成一個被「挑戰」問題時超開心，被「質疑」問題時興奮無比的人。 問，為什麼人生不能想做什麼就做什麼？ 問，為什麼學思考，就等於學做人？ 問，為什麼被挑戰、被質疑，反而會高興？ 問，為什麼謹慎小心不好？ 問，為什麼有錢人不會成為物質的奴隸？ 問，為什麼我不能幫爸媽安排他們的人生？ 問，為什麼要學習「享受」問題，而不是「解決」問題？ 人生階段百百問，但是如果我們開始動腦思考，其實就已經踏入改變自己的第一步。 《我為什麼去法國上哲學課？》實踐篇最大的特點在於，本書將強調如何使用思考的技巧，幫助我們每一天的生活。而最好的方法就是從觀察開始，任何生活裡的小事，都可以去問「為什麼會這樣？」「為什麼會有這個現象？」 不論是跟人一句短短的對話，還是我們聽到的一句話，都可以觀察自己的反應與情緒。 如此一來「每一件事情都可以想，世界上沒有任何一件不可以想的事情，從此以後我沒有任何一個時刻是無聊的，因為就算聽到很無聊的話，也可以觀察這個人為什麼會說這麼無聊的話？他真的相信說的這些話嗎？如果他不相信 ，為什麼他覺得他要說呢？」 本書也等於透過實例舉證，讓讀者像是親臨「哲學諮商」的實境，在每一個生活上會產生的問題，如人與人之間的溝通、對未來的徬徨與抉擇、金錢的價值觀，最重要的是釐清複雜的人際關係，學習相處與成長。當我們將問題透 過「哲學思考」來一層一層推理，最終我們都回到最原始的關鍵上，那就是：「我是一個 什麼樣的人？」「我認識我自己嗎？」「我了解自己嗎？」「我愛自己嗎？」 本書特色 工作無法趁心如意，對未來茫然不知方向，到底該轉職？還是繼續忍耐熬？ 你其實想大吼：人生難道不能想做什麼就做什麼嗎？ 越想完美經營人脈，越抓不到重點，你有沒有想過自己對「人際關係」很貪心？ 好了，現在下決心脫離舒適圈，好像自由高飛了， 但你也許在「更保守的國外」原地踏步繞圈圈…… 以上問號絕對不是「跟著感覺走」就能夠得到答案，也不是別人的答案，可以先偷來用。 你如何找到屬於自己的路？ 哲學思考實踐→尋找適合自己的思考方法 ★用第三者的角度來看自己。 ★學習享受問題，而不是解決問題。 ★善用「刪去法」知道自己不要什麼。 ★「跟著感覺走」不是真思考。 ★人生充滿未知，請不要過度準備。 ★把每一個意外，都當成一個禮物。 ★不斷練習，養成有紀律的思考習慣。.

We study a joint pricing and inventory control problem for perishables with positive lead time in a finite horizon periodic-review system. Unlike most studies considering a continuous density function of demand, in our paper the customer demand depends on the price of current period and arrives according to a homogeneous Poisson process. We consider both backlogging and lost-sales cases, and our goal is to find a simultaneously ordering and pricing policy to maximize the expected discounted profit over the planning horizon. (...) When there is no fixed ordering cost involved, we design a deep reinforcement learning algorithm to obtain a near-optimal ordering policy and show that there are some monotonicity properties in the learned policy. We also show that our deep reinforcement learning algorithm achieves a better performance than tabular-based Q-learning algorithms. When a fixed ordering cost is involved, we show that our deep reinforcement learning algorithm is effective and efficient, under which the problem of “curse of dimension” is circumvented. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Teaching the Trinity:Scripture and Performance of the Psychological Analogy in Aquinas's Summa TheologiaeZane E. ChuTeaching the Trinity, for St. Thomas Aquinas, takes its point of departure from Sacred Scripture. He makes this explicit at the outset of the Trinitarian treatise in the Summa theologiae, citing Christ's words at John 8:42, "from God I proceeded," and affirming, "divine Scripture in the things of divinity, uses words that pertain to procession."1 (...) The order of teaching then continues through speculative effort to give an account of the scriptural witness to the distinction of persons in God, in order to return to the same Scripture with a deeper grasp of its meaning.2Aquinas is a master of the sacred page, and his basic pedagogy for theology involves the "exercises of Sacred Scripture" of reading, disputing, and preaching.3 Recent scholarship draws attention to his reading of Scripture [End Page 1149] expressed in biblical commentaries as foundational for his teaching and as an interpretive context for his summative works.4 My purpose is to illustrate this basic pedagogy in the Trinitarian treatise of the Summa theologiae, taking the Lectura super Ioannem as an interpretive context for the analogies of word and love—the psychological analogy—for the Trinity. Most scholarly discussion of the psychological analogy elaborates on its theoretical aspects, with some attention to its scriptural foundation.5 I wish to show the priority of Scripture in Aquinas's employment of this analogy in three respects, namely, its foundation in exegesis, performative aspects, and orientation toward preaching.My investigation focuses on question 27 of the prima pars alongside pertinent sections of the Super Ioannem. I argue that citations from the Gospel of John (8:42, 15:26, and 14:16) in the sed contras of articles 1 and 3 function to ground the psychological analogy in scriptural exegesis and to prompt its performance. Turning to the corresponding commentary shows Aquinas leading the student to knowledge of Christ as divine Word and to love of him from the Holy Spirit that both leads to and follows upon such knowledge. This provokes an affective experience of loving Christ in knowing his divinity that is an actual performance of the psychological analogy. The magisterial responses then use this affective experience as a basis to facilitate a grasp of the analogy, the articulation of which is a further guided performance that reflects on this experience. Aquinas teaches the Trinity by exercising the student both affectively and intellectually in its scriptural foundation for a deeper grasp that prepares for preaching. I develop my argument in three [End Page 1150] main steps. First, I specify the place of Scripture in Aquinas's teaching and review the composition of the Trinitarian treatise. Then, I examine the first four articles of question 27 and corresponding sections of the Super Ioannem, in the order of the analogies of word and of love. Lastly, I consider Aquinas's treatment of the Holy Spirit's proper name of Love and subsequent preaching to illustrate Scripture as a point of arrival through performance of the psychological analogy.The Place of Scripture in Aquinas's TeachingFor Aquinas, Scripture is placed within his broader practice of sacra doctrina or holy teaching, attention to which assists in demonstrating how the Johannine citations ground the psychological analogy in Scripture and prompt its performance. Sacra doctrina has a primarily pastoral orientation, namely, to form Dominicans for preaching and hearing confessions.6 Though more speculative than practical, sacra doctrina as speculation or contemplation of the truth of Christian faith contained in Scripture is to be handed on to others.7 This requires training in the scriptural exercises of reading and disputing as preparation for preaching. These may be taken as "spiritual exercises" that engage not only thought, but also affectivity in service of personal transformation for the preacher's way of life.8 Aquinas's practice of sacra doctrina begins with reading Scripture as expressed in biblical commentaries, and develops in the Summa theologiae, which accesses Scripture through citations to offer a summative grasp of the truth contained therein. Here, I review the formal aspects of Aquinas's teaching from Scripture in these texts... (shrink)

This study examines the role of codes of ethics in reducing the extent to which managers act opportunistically in reporting earnings. Corporate codes of ethics, by clarifying the boundaries of ethical corporate behaviors and making relevant social norms more salient, have the potential to deter managers from engaging in opportunistic financial reporting practices. In a sample of international companies, we find that the quality of corporate codes of ethics is associated with higher earnings quality, i.e., lower discretionary accruals. Our results (...) are confirmed for a subsample of firms more likely to be engaging in opportunistic reporting behavior, i.e., firms that just meet or beat analysts’ forecasts. Further, codes of ethics play a greater role in reducing earnings management for firms in countries with weaker investor protection mechanisms. Our results suggest that corporate codes of ethics can be a viable alternative to country-level investor protection mechanisms in curbing aggressive reporting behaviors. (shrink)
