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)

Discovering the underlying mathematical expressions describing a dataset is a core challenge for artificial intelligence. This is the problem of symbolic regression. Despite recent advances in training neural networks to solve complex tasks, deep learning approaches to symbolic regression are underexplored. We propose a framework that leverages deep learning for symbolic regression via a simple idea: use a large model to search the space of small models. Specifically, we use a recurrent neural network to emit a distribution over tractable mathematical (...) expressions and employ a novel risk-seeking policy gradient to train the network to generate better-fitting expressions. Our algorithm outperforms several baseline methods (including Eureqa, the gold standard for symbolic regression) in its ability to exactly recover symbolic expressions on a series of benchmark problems, both with and without added noise. More broadly, our contributions include a framework that can be applied to optimize hierarchical, variable-length objects under a blackbox performance metric, with the ability to incorporate constraints in situ, and a risk-seeking policy gradient formulation that optimizes for best-case performance instead of expected performance.

BackgroundEthics is the science of moral and ethical rules recognised in human life and attempts to verify what is morally right and wrong. Healthcare ethics is seen as an integrated part of the daily activities of health facilities. Healthcare professionals’ standardisation and uniformity in healthcare ethics are urgent and basic requirements. Therefore, this study aimed to assess the practice of the code of ethics and associated factors among health professionals in Central Gondar Zone public hospitals, Northwest Ethiopia, 2021.MethodsA facility-based cross-sectional (...) study design with a mixed method was conducted on 631 health professionals from Central Gondar Zone public hospitals. For the quantitative part, pre-tested self-administered questionnaires were used, and for the qualitative part, key informant interviews with a semi-structured questionnaire were used. Variables with a p value of < 0.2 in binary logistic regression entered into a multivariable logistic regression, then p value < 0.05 and AOR were used to declare statistically significant variables in quantitative data. A thematic content analysis was used for qualitative data analysis.ResultsThis study revealed that only 286 health professionals had good practice of the code of ethics. Good ethical knowledge, favourable attitude, and satisfaction of health professionals with their jobs were significantly associated with the practice of health care ethics.ConclusionsHealth professionals' overall level of practice of health care ethics in the Central Gondar Zone public hospitals was poor. This necessitates practical training, ongoing follow-up, availing of necessary medical equipment, a smooth working environment, and modification of the recognition system for health professionals.

In his ‘The Identity Objection to the future‐like‐ours argument’ (Bioethics, 2019, 33: 287–293), Brill argues that Marquis's 'future of value' account of the wrong of abortion is still vulnerable to the identity objection—the claim that the foetus and the later person are not numerically identical, so the later person's valuable experiences are not the foetus's future experiences—even if it is conceded that the future organism, as well as the person, has experiences. This is because the organism has these experiences in (...) a different way from the person. The person has them directly, and the organism has them only derivatively. This implies, he maintains, that the organism cannot be deprived of those experiences in a way that is wrong. Only the person can be deprived in this morally relevant way. But, I argue, if the organism genuinely has those experiences, it is not at all clear why its being deprived of them would be permissible. I argue that the reason why Brill can claim that having those experiences derivatively makes this moral difference is because the sense in which the organism has experiences is not a genuine sense. But that is a problem for this theory of personal identity, not for Marquis's account of the wrong of abortion. I also argue that supposing that one cannot morally harm the human organism has various implausible implications, which cast doubt on the idea that having experiences derivatively means that the organism is not morally harmed by being deprived of them.

I defend the buck-passing account of value from Dancy's critique.

_Kant, Duty and Moral Worth _is a fascinating and original examination of Kant's account of moral worth. The complex debate at the heart of Kant's philosophy is over whether Kant said moral actions have worth only if they are carried out from duty, or whether actions carried out from mixed motives can be good. Philip Stratton-Lake offers a unique account of acting from duty, which utilizes the distinction between primary and secondary motives. He maintains that the moral law should (...) not be understood as a normative moral reason but as playing a transcendental role. Thus a Kantian account of moral worth is one where the virtuous agent may be responsive to concrete particular considerations, whilst preserving an essential role for universal moral principles. _Kant, Duty and Moral Worth _is a lucid examination of Kant's moral thought that will appeal to Kant scholars and anyone interested in moral theory.

Ethical Intuitionism was the dominant moral theory in Britain for much of the 18th, 19th and the first third of the twentieth century. However, during the middle decades of the twentieth century ethical intuitionism came to be regarded as utterly untenable. It was thought to be either empty, or metaphysically and epistemologically extravagant, or both. This hostility led to a neglect of the central intuitionist texts, and encouraged the growth of a caricature of intuitionism that could easily be rejected before (...) moving on to 'more serious' philosophical theories. More recently, however, this hostility towards ethical intuitionism has subsided. A wide range of moral philosophers, from Aristotelians, to rule-consequentialists, to expressivists, Kantians and deontologists, are beginning to look to the ethical intuitionists's work as a positive resource. It is, therefore, a good time to get clear on what it was that intuitionists said, and re-evaluate their contribution to our understanding of morality. This volume is the first serious engagement with ethical intuitionism in the light of contemporary developments in ethical theory. It contains essays by eminent moral philosophers working in very different traditions whose aim is to clarify and assess ethical intuitionism. Issues addressed include whether the plurality of basic principles intuitionists adhere to can be grounded in some more fundamental principle; the autonomy of ethics and self-evidence; moral realism and internalism; and the open question argument and naturalism.

The Right and the Good, a classic of twentieth-century philosophy by the great scholar Sir David Ross, is now presented in a new edition with a substantial introduction by Philip Stratton-Lake, a leading expert on Ross. Ross's book is the pinnacle of ethical intuitionism, which was the dominant moral theory in British philosophy for much of the nineteenth and early twentieth century. Intuitionism is now enjoying a considerable revival, and Stratton-Lake provides the context for a proper understanding of (...) Ross's great work today. (shrink)

According to ethical intuitionists, basic moral propositions are self-evident. Robert Audi has made significant progress articulating and defending this view, claiming that an adequate understanding of a self-evident proposition justifies rather than compels belief. It is argued here that understanding a proposition cannot justify belief in it, and that intuition, suitably understood, provides the right sort of justification. An alternative account is offered of self-evidence based on intuition rather than understanding, and it is concluded that once we have an adequate (...) understanding of a self-evident proposition, we can see that it does no distinctive epistemic work. It merely reports that intuition is doing some significant epistemic work. Since the very idea of self-evident moral propositions is so controversial, and self-evidence does no significant epistemic work, ethical intuitionists should drop this notion from their moral epistemology. All they need are intuitive propositions and our intuition of these. (shrink)

This article aims to explore the attitudes and behaviors of persons with intellectual and developmental disabilities related to their information privacy when using information technology. Six persons with IDD were recruited to participate to a series of 3 semistructured focus groups. Data were analyzed following a hybrid thematic analysis approach. Only 2 participants reported using IT every day. However, they all perceived IT use benefits, such as an increased autonomy. Participants demonstrated awareness of privacy concerns, but not in situations involving (...) the use of technology; their awareness is not transferred to the abstract context of IT use. Privacy breaches were revealed to be a major risk for persons with IDD, who did not seem to understand how their personal information was used. Most protection mechanisms and tools reported were those suggested and implemented by caregivers and close relatives who had a great influence on the participants’ attitudes and behaviors toward IT and privacy. Our findings suggest that when using IT, persons with IDD often experience the consequences of a trade-off between autonomy and privacy. Further research and action is needed to support persons with IDD to understand and balance the benefits of IT use and the inherent threats to information privacy. (shrink)

In this paper I argue that the best form of deontology is one understood in terms of prima facie duties. I outline how these duties are to be understood and show how they offer a plausible and elegant connection between the reason why we ought to do certain acts, the normative reasons we have to do these acts, the reason why moral agents will do them, and the reasons certain people have to resent someone who does not do them. I (...) then argue that this form of deontology makes it harder to unify a pluralistic ethics under a single consequentialist principle in a plausible way, and illustrate this with reference to Rob Shaver's consequentialist arguments.

Here I argue that the best form of deontology is an ethic of prima facie duties, and that this form of deontology is especially resistant to any form of reduction to a single principle.

_ Source: _Page Count 18 Bart Streumer argues that all normative properties are descriptive properties. His first argument is based on the principle that necessarily coextensive predicates ascribe the same property, and the claim that there is a descriptive predicate that is necessarily coextensive with normative predicates. From this Streumer concludes that normative properties are identical with descriptive properties. I argue that, even if we accept, this conclusion does not follow. Normative properties could only be descriptive properties if there is (...) some descriptive way in which all instances of normative properties are similar. But Streumer does not show that, and the prospects for doing so are, I believe, not good. His second argument rests on the premise that the nature of normative properties cannot depend on which first order normative theory is true. I argue that this premise is false, and that the argument for it does not sit comfortably with. (shrink)

Ethical intuitionists are often criticised on the ground that their view makes it possible for an agent to believe that she ought to ? whilst lacking any motive to ?-that is, on the ground that it involves, or implies a form of externalism. I begin by distinguishing this form of externalism (what I call 'belief externalism') from two other forms of ethical externalism-moral externalism, and reasons externalism. I then consider various reasons why one might think that ethical intuitionism is defective (...) in so far as it involves, or implies belief externalism, and argue that these objections are unpersuasive.

The buck-passing account of value involves a positive and a negative claim. The positive claim is that to be good is to have reasons for a pro-attitude. The negative claim is that goodness itself is not a reason for a pro-attitude. Unlike Scanlon, Parfit rejects the negative claim. He maintains that goodness is reason-providing, but that the reason provided is not an additional reason, additional, that is, to the reason provided by the good-making property. I consider various ways in which (...) this may be understood and reject all of them. So I conclude that buck-passers cannot reject the negative claim. (shrink)

According to one formulation of Scanlon’s contractualist principle, certain acts are wrong if they are permitted by principles that are reasonably rejectable because they permit such acts. According to the redundancy objection, if a principle is reasonably rejectable because it permits actions which have feature F, such actions are wrong simply in virtue of having F and not because their having F makes principles permitting them reasonably rejectable. Consequently Scanlon’s contractualist principle adds nothing to the reasons we have not to (...) act wrongly and is redundant. (shrink)
