We propose a new Real-coded GA(RCGA) using the combination of two crossovers, UNDX-m and EDX. The search region of UNDX-m is biased to the inside area that the population of the RCGA covers. Because of this search bias, the GA using UNDX-m causes stagnation of its search if the cost function has a kind of structure, so called, a ridge structure or a multiple-peak structure. In order to overcome this stagnation, we propose a new crossover EDX, whose search is biased (...) toward extrapolative one. Experimental results show that RCGA with EDX can deal with both ridge-structure function whose dimension reaches more than hundreds and multiple-peak function whose optimum resides at the corner of the search area.

Translated into English for the first time, leading Japanese philosopher, Nishihira Tadashi, explores the deeply experiential philosophy of losing yourself in the reality of the present. He takes us on a tour through the history of Zen, the gatekeeper of the philosophy of no-mind D.T. Suzuki, the Noh theory of Zeami and Takuan's treatise on swordsmanship. Nishihira pulls together the threads of this genealogy of no-mind, showing the richness of the concept and its essential connection to the paradoxical task (...) of becoming fully human. (shrink)

「稽古」とはいかなる思想か。そこに秘められた「智恵」が意味するものとは。「稽古」を知の地平に解き放ち、こころとからだと世界のありかを探る、注目の書。.

Unlearning is a recurrent theme in Japan. To further understanding of what this entails, we focus on the view of learning laid out by a revered 13th century Zen-inspired playwright. For Zeami, learning involved a movement from the acquisition to unlearning of skills, punctuated by an experience of mushin, followed by creative reemergence. To deepen understandings of this unlearning model, we turn to draw comparison with recent discussions in the Western literature, focusing on Double-Loop Learning and Learning III, both inspired (...) by Bateson. Learning III, which Bateson utilized several Zen references to explicate, appears to gesture towards the alternative punctuation of learning envisaged by Zeami, although differences remain. We then shift to highlight empirical work on contemporary Japanese schooling, highlighting practices which suggest elements of a Zeami-like worldview continue to live on in Japan’s learning culture. Unlearning, when viewed as a living tradition embedded in culture, rather than merely a premodern past or future philosophical possibility, help sets the stage for a transnational, transdisciplinary dialogue on how we learn. We perform our own extended dialogue that led to this piece, a mode of engagement we view as methodological innovation, as we work to unlearn our past parochialisms. (shrink)

This essay introduces Walter Benjamin’s historical materialism to illuminate how history teachers may invoke a critique of the past and present through democratizing the production of knowledge in the classroom. Historical materialism gives students access to the means of knowledge production and entrusts them with the task of generating a critique of politics though encounters with historical objects. The rise of the alt-right, alternative facts, and fake news sites necessitates social studies methods that intervene into the fascist seductions of narrative (...) in history. A Benjaminian pedagogy emphasizes reading practices that acknowledge the political layers of history inscribed within the objects. This generates space for forms of pessimism and dialectic critiques of barbarism that students may experience with history beyond the teacher’s capacity for understanding. In the name of democracy over fascism, the article adds a political critique to students’ historical and critical thinking skills. (shrink)

「無心」は、最高のパフォーマンスをもたらす境地であり、それは憧れの対象であり続けた。達磨の禅、世阿弥の伝書、武道の教え、石田梅岩の心学、鈴木大拙の禅研究など、異なる時代、異なる文脈の中で、「無心」はど のように問われてきたのか。「無心」という言葉のもとに育まれた思考のいとなみを描き出すことで、柔軟でしなやかな心のあり方、その融通無碍な活力の深奥にせまる。.

This paper presents the Real-coded Genetic Algorithms(RCGA) which can treat with high-dimensional ill-scaled structures, what is called, k -tablet structure. The k -tablet structure is the landscape that the scale of the fitness function is different between the k -dimensional subspace and the orthogonal (n-k) -dimensional subspace. The search speed of traditional RCGAs degrades when high-dimensional k -tablet structures are included in the landscape of fitness function. In this structure, offspring generated by crossovers is likely to spread wider region than (...) the region where the parental population covers. This phenomenon causes the stagnation of the search. To resolve this problem, we propose a new crossover LUNDX- m, which uses only m -dimensional latent variables. The effectiveness of the proposal method is tested with several benchmark functions including k -tablet structures and we show that our proposal method performs better than traditional crossovers especially when the dimensionality n is higher than 100.

This paper presents a kernel density estimation method by means of real-coded crossovers. Functions of real-coded crossover operators are composed of probabilistic density estimation from parental populations and sampling from estimated models. Real-coded Genetic Algorithm (RCGA) does not explicitly estimate probabilistic distributions, however, probabilistic model estimation is implicitly included in algorithms of real-coded crossovers. Based on this understanding, we exploit the implicit estimation of probabilistic distribution of crossovers as a kernel density estimator. We also propose an application of crossover kernels (...) to Expectation-Maximization estimation (EM) of Gaussian mixtures. (shrink)

The paper explores the emergence and development of socially responsible investment (SRI) in Japan. SRI is a recent field in Japan. It is not clear which model it will follow: the European, American or its own model. Through the analysis of the historical roots of SRI, the key actors and motivations that have contributed to its diffusion, the paper provides explorative grounds to sketch the translation mechanisms of SRI in Japan and offers insight into its future path. Based on primary (...) and secondary sources of information, the paper shows that although SRI in Japan holds some similarities with the U.S. and especially with the European model, it remains unique. It highlights the importance of translation and re-interpretation in adopting a practice in a new context. SRI in Japan is still in a dynamic construction process. Although we expect it to develop further, it is difficult to depict its future shape and form. (shrink)

いま、なぜ日本の思想なのか。出発点としての問いかけ。近代において日本思想の研究が立ち上がって行く過程、日本的なるものへの問い、多様な「日本」観などを検討する。.

Today, at the close of the twentieth century, we are confronted by radical changes in the nature of intercultural relations. Those who in previous centuries were unable to venture far from their native villages are today able to visit foreign lands as a matter of course, not only as tourists but also for reasons of commerce or employment. A high degree of intercultural understanding is manifested thereby. But at the same time there arise cultural conflicts and friction. How is that (...) sort of understanding which transcends cultural frontiers possible at all? And what is the root of the different sorts of failure to achieve intercultural communication? These are pressing problems by which mankind as a whole is confronted, and they are problems which philosophers, too, are called upon to face. (shrink)
