Recent progress in artificial intelligence has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats that of humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking (...) machines will have to reach beyond current engineering trends in both what they learn and how they learn it. Specifically, we argue that these machines should build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; ground learning in intuitive theories of physics and psychology to support and enrich the knowledge that is learned; and harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes toward these goals that can combine the strengths of recent neural network advances with more structured cognitive models. (shrink)

Both scientists and children make important structural discoveries, yet their computational underpinnings are not well understood. Structure discovery has previously been formalized as probabilistic inference about the right structural form—where form could be a tree, ring, chain, grid, etc.. Although this approach can learn intuitive organizations, including a tree for animals and a ring for the color circle, it assumes a strong inductive bias that considers only these particular forms, and each form is explicitly provided as initial knowledge. Here we (...) introduce a new computational model of how organizing structure can be discovered, utilizing a broad hypothesis space with a preference for sparse connectivity. Given that the inductive bias is more general, the model's initial knowledge shows little qualitative resemblance to some of the discoveries it supports. As a consequence, the model can also learn complex structures for domains that lack intuitive description, as well as predict human property induction judgments without explicit structural forms. By allowing form to emerge from sparsity, our approach clarifies how both the richness and flexibility of human conceptual organization can coexist. (shrink)

We were encouraged by the broad enthusiasm for building machines that learn and think in more human-like ways. Many commentators saw our set of key ingredients as helpful, but there was disagreement regarding the origin and structure of those ingredients. Our response covers three main dimensions of this disagreement: nature versus nurture, coherent theories versus theory fragments, and symbolic versus sub-symbolic representations. These dimensions align with classic debates in artificial intelligence and cognitive science, although, rather than embracing these debates, we (...) emphasize ways of moving beyond them. Several commentators saw our set of key ingredients as incomplete and offered a wide range of additions. We agree that these additional ingredients are important in the long run and discuss prospects for incorporating them. Finally, we consider some of the ethical questions raised regarding the research program as a whole. (shrink)

Neural network models have recently made striking progress in natural language processing, but they are typically trained on orders of magnitude more language input than children receive. What can these neural networks, which are primarily distributional learners, learn from a naturalistic subset of a single child's experience? We examine this question using a recent longitudinal dataset collected from a single child, consisting of egocentric visual data paired with text transcripts. We train both language-only and vision-and-language neural networks and analyze the (...) linguistic knowledge they acquire. In parallel with findings from Jeffrey Elman's seminal work, the neural networks form emergent clusters of words corresponding to syntactic (nouns, transitive and intransitive verbs) and semantic categories (e.g., animals and clothing), based solely on one child's linguistic input. The networks also acquire sensitivity to acceptability contrasts from linguistic phenomena, such as determiner-noun agreement and argument structure. We find that incorporating visual information produces an incremental gain in predicting words in context, especially for syntactic categories that are comparatively more easily grounded, such as nouns and verbs, but the underlying linguistic representations are not fundamentally altered. Our findings demonstrate which kinds of linguistic knowledge are learnable from a snapshot of a single child's real developmental experience. (shrink)

The question of bias in methodology and terminology is a problem that faces researchers east, west, north and south; however, it faces Third World intellectuals with special keenness. For although they write in a cultural environment that has its own specific conceptual and cultural paradigms, they nevertheless encounter a foreign paradigm which attempts to impose itself upon their society and upon their very imagination and thoughts. When the term “developmental psychology” for instance is used in the West Arab scholars also (...) say “developmental psychology”, when “applied psychology” is mentioned they hurry to use the same term etc. Why not establish a new science with its own mechanisms, methodologies and points of reference to deal with epistemological biases and open up the gate of ijtihad with respect to them? This collection of papers aims to discover some of the biases latent in our terminology, methodologies, research tools, and conceptual principles, and to propose alternative ones marked by a greater degree of independence and neutrality. This is not to belittle the human value of the West’s creative contributions but to emphasize the danger of making it the ultimate point of reference and then trying to continuously play “catch up” with it.

The present study is the first to empirically test a hierarchical, positive-oriented model of self and its relationship to the second language (L2) achievement motivation, and compare it in three different cultural contexts of Japan, U.S. and Taiwan. Based on the L2 self model (Lake, 2016), three levels of constructs were developed: Global Self (i.e., Flourishing, Curiosity, and Hope); Positive L2 domain self (i.e., interested-in-L2 self, harmonious passion for L2 learning, and mastery L2 goal orientation); and L2 Motivational Variables (...) (i.e., reading, speaking and listening self-efficacy). A total of 667 students participated in this study, including 181 first-year college students in Japan, 159 high school students in Taiwan, and 327 college students in the U.S. All the participants were learning a L2 in school. Results showed that the measures of positive global self, L2 domain self, and L2 motivational self all had a stronger relationship within their respective levels, and progressively weaker relationships as level of generality/specificity became more distal. Furthermore, the relationships among measures varied in the differing cultural contexts with the Japan-based student participants relatively lower on all measures. (shrink)

Prospective follow-up studies have shown that even though some children outgrow the disorder, a childhood diagnosis of attention deficit hyperactivity disorder is clearly a risk factor for a broad range of adverse outcomes, with extremes including drug abuse and juvenile delinquency. This article considers the use of several spectrum concepts and some neuroethical issues. It provides a list of criterion symptoms with a threshold set for the number of symptoms required for categorical diagnoses of disorders. It gives a brief review (...) of some brain imaging and pharmacological treatment studies of ADHD to set the stage for a consideration of brain-specific issues related to neuroethics. Studies using reaction time tasks of cognitive control, response inhibition, and conflict have identified interindividual variance in task performance as one of the most prominent aspects of cognitive deficits related to ADHD.

In lieu of an abstract, here is a brief excerpt of the content: Classics and Complexity in Walden’s “Spring” M. D. USHER In 1843, two years before Henry Thoreau built his cabin at Walden Pond, the Fitchburg Railroad laid down tracks through the woods near the Pond for its line connecting Boston to Fitchburg. The original Fitchburg Line, at 54 miles long, was, until 2010, the longest run in the present -day MBTA Commuter Rail system. And it is one of (...) the oldest railways in New England. By 1900, fortunes swelled and the Fitchburg’s Hoosac Tunnel Line took passengers and goods westward toward Chicago. The Lake Champlain Route connected Boston to points north like Burlington, Vermont. (See Figure 1.) arion 27.1 spring/summer 2019 Figure 1 (left): Advertisement for the Hoosac Tunnel Route in The New England Magazine (Vol. 21, Issue 6, February, 1900). Figure 2 (right): Herbert Wendell Gleason. The Fitchburg Railroad and Walden Pond in winter, Concord, Mass., March 24, 1920. Courtesy Concord Free Public Library. The Railroad was literally a fixture in Thoreau’s landscape. Its tracks pass remarkably close to Walden Pond (Figure 2), and the Fitchburg Line—both its reality and the specter of it—is practically a character in his writing: “I usually go to the village along its causeway, and am, as it were, related to society by this link,” Thoreau writes in “Sounds,” a chapter of Walden that contains what must be one of the most picturesque odes (or laments) to rail travel and commerce in all of American literature: The engine’s whistle, Thoreau complains, pierces the still silence of his idyllic retreat like a screaming hawk circling a farmer’s field, its billows of steam an ominous harbinger of “this travelling demi-god, this cloud-compeller.”1 Thoreau’s frequent, customary walks into Concord along the railroad tracks took him through a heavily excavated stretch of the line known as the Deep Cut, to which he returned again and again each year in early spring, even after leaving the cabin, to observe and to record his observations. The leaf-shaped sand flows and trickling surface erosion caused by melting frost in the banks of the Deep Cut are elaborately described in Thoreau’s chapter in Walden entitled “Spring,” what Laurence Buell calls the “high point of Thoreau’s epic.”2 And yet, in spite of the universal acclaim of this passage as a literary tour de force, it has not received the full attention it deserves. What warrants fresh consideration first and foremost is “Spring”’s deep-rootedness in classical sources. Many classical influences, allusions, and a good deal of etymological word play have gone so far unnoticed. The chapter is also important because it describes, by intimation, what contemporary scientists now call emergence. Emergent phenomena are properties or behaviors that arise in systems as a result of complex, dynamic interactions amongst constituent parts, including changes to a system brought about by human interventions3—not only, e.g., climate change and wildfires, but also traffic patterns and terrorist networks; kidney function in the body; the rings of Saturn. As he tries to capture the essence of the 114 classics and complexity in WALDEN’s “spring” Deep Cut and interpret its significance, Thoreau adumbrates this concept, but also grapples ingeniously with broader issues of perennial concern—the relationship of Nature to Culture, for example, of Wilderness to Civilization, of Science to the Humanities—making “Spring” not only a probing work of eco-criticism and environmental philosophy, but of scientific reflection and poetic experiment as well. In short, Thoreau’s “Spring” is that rare work of classical reception that transmits both literary and scientific insight. Perhaps at this point, in lieu of accolades, it is best to let Thoreau start speaking for himself. What I offer in the following pages is a commentary on the Deep Cut passage from “Spring.” Classical references and aspects of systems theory will be explained and contextualized as they emerge, as it were, from Thoreau’s text. The whole chapter corresponds to pages 289–308 in Cramer’s edition of Walden—26 paragraphs all told, of which only the relevant ones are printed and annotated here.

The solution to the problem posed by the presentation of the giant turbot to Domitian is put forward by Montanus, a gourmet well qualified to adjudicate in such matters: one bite was sufficient for him to distinguish between oysters from Circeii, the Lucrine, or Richborough . The text reads.

Hydrological landscapes played a significant role in the elaboration of Gaston Bachelard’s and Martin Heidegger’s historical epistemologies. More specifically, both philosophers relied on hydroelectric landscapes to explore nonlinear time and profound epistemological shifts in the history of knowledge. The landscapes they invoke are composed of hydroelectric dams, thunderstorms, and related landmarks like mountains, rivers, and lakes. Together, these varied yet connected elements offer rich environmental and conceptual terrains that I revisit to situate human knowledge formation within a much older natural (...) history, and to lay the groundwork for a deep time theory of knowledge. Such theories promote timefulness and geological consciousness by establishing less anthropocentric historical narratives – or what Dipesh Chakrabarty calls “planetary history” – on more suitable epistemological grounds.

Water quality control helps in the estimation of water bodies and detects the span of pollutants and their effect on the neighboring environment. This is why the water quality of the northern part of Lake Manzala has been studied here from January to March, 2016. This study aims to model and create a program for linear and nonlinear regression of the water elements in Lake Manzala to assess and predict the water quality. Water samples have been extracted from (...) various depths, and physio-chemical properties and heavy metal concentrations have been evaluated. This study has proposed a new algorithm for predicting water quality called “Algorithm of Estimation Regression Model”. On the contrary, in renewable energy applications, statistical modeling and forecasting the solar radiation remains a significant issue with detect to reinforce power management. A new proposed method for forecasting the average Monthly Global Solar Energy in Queensland, Australia, is called, Converting Data Set into Markov Model. It was used to obtain Markov transition probability matrices for three and six states of the solar energy. The proposed forecasting method yielded accurate results with minimal error. (shrink)

The Second Conference of the International Society for the Study of Time was held at Hotel Mt. Fuji, near Lake Yamanaka, Japan, on July I to 7,1973. The present volume is the proceedings at that Con ference and constitutes the second volume in The Study of Time series. * At the closing session of our First Conference in Oberwolfach, Germany, in 1969, I was honored by being elected to the Presidency of the Society, following Dr. J. G. Whitrow, our (...) fIrst President. My mandate was to organize a Second Conference, consistent with the aim of the Society, which is the holding of interdisciplinary conferences for the presentation and discussion of papers on various as pects of time. Several participants expressed to me their wish to have a second conference held in Japan so as to emphasize the international and intercultural dedication of this Society. Dr. Fraser carefully evaluated this and many other suggestions, weighed the possible conference sites and our chances of raising the necessary funds to convene a meeting at such sites, and concurred with my conclusions that we should go ahead with the plans for a Japanese meeting. For the difficult and complicated task of raising funds and organizing a conference in Japan, I had to select and rely heavily on somebody both capable and reliable and also living in Japan. Thus, I asked the Reverend Michael Mutsuo Yanase, S. J. (shrink)

George Greenough was one of the influential group of early nineteenth-century English geologists who rejected both Hutton's and Werner's attempts to propound all-embracing geological theories, and followed a deliberately empirical approach. He travelled through Scotland in 1805, studying geological phenomena in the light of both the Plutonist and the Neptunist theories, and generally concluded that neither was entirely satisfactory as an explanation of the observable facts. He was also the first to suggest that the ‘Parallel Roads’ of Glen Roy were (...) the successive beach-levels of a former lake: this theory was later attacked by Darwin but ultimately vindicated by Agassiz's glacial theory. The more important geological passages from Greenough's MS. journal of the tour are reproduced and discussed in this paper. They illustrate some of the scientific problems that were involved in accepting either Hutton's or Werner's theory entire. (shrink)

Harmful algal blooms in Lake Erie’s western basin are caused in large part by nutrient loss from agricultural production. While use of nutrient management practices is encouraged to reduce agricultural nutrient loss and its consequent environmental impacts, such practices are not universally adopted. This study aims to better understand the factors that influence western Lake Erie basin farmers’ risk perceptions associated with agricultural nutrient loss, and thus further our knowledge of how adoption of nutrient management practices may be (...) increased. We propose a conceptual model to explain the relationships that we hypothesize to influence farmers’ risk perceptions associated with agricultural nutrient loss. Specifically, we consider the roles that farmer conservation identity, farmers’ perceived sufficiency of their nutrient management practices, and land vulnerability to nutrient loss play in influencing risk perceptions. We find that many of the hypothesized relationships are not statistically significant, and that risk perception associated with nutrient loss is primarily driven by farmers’ conservation identities. While farmers’ perceived sufficiency of their nutrient management practices plays some role in governing risk perceptions, we do not observe the hypothesized relationship between land vulnerability to nutrient loss and perceived sufficiency of nutrient management practices.

The title of my paper may look odd. If one is questioned “What is a dog?”, everyone could give a more or less valid answer. But to the question “What is not a dog?”, there can be innumerable answers which may be correct, but mostly quite unhelpful. Provisionally, what I intend to do under this title is to consider what we should not hold time to be. Through the history of ideas we meet various opinions and theories concerning what time (...) is. But it seems to me that most of them are not adequate enough, though each has its reason and often profound import as well. So I would like here to make a proposal for reconsidering how time appears in our life and thinking. (shrink)

The article develops and extends the theory of Glenn Kessler (Frege, Mill and the foundations of arithmetic, Journal of Philosophy 77, 1980) that a (cardinal) number is a relation between a heap and a unit-making property that structures the heap. For example, the relation between some swan body mass and "being a swan on the lake" could be 4.
