Belief and Credence: Why the Attitude-Type Matters
In this paper, I argue that the relationship between belief and credence is a central question in epistemology. This is because the belief-credence relationship has significant implications for a number of current epistemological issues. I focus on five controversies: permissivism, disagreement, pragmatic encroachment, doxastic voluntarism, and the relationship between doxastic attitudes and prudential rationality. I argue that each debate is constrained in particular ways, depending on whether the relevant attitude is belief or credence. This means that epistemologists should pay attention to whether they are framing questions in terms of belief or in terms of credence and the success or failure of a reductionist project in the belief-credence realm has significant implications for epistemology generally
Credence for Epistemic Discourse
Many recent theories of epistemic discourse exploit an informational notion of consequence, i.e. a notion that defines entailment as preservation of support by an information state. This paper investigates how informational consequence fits with probabilistic reasoning. I raise two problems. First, all informational inferences that are not also classical inferences are, intuitively, probabilistically invalid. Second, all these inferences can be exploited, in a systematic way, to generate triviality results. The informational theorist is left with two options, both of them radical: they can either deny that epistemic modal claims have probability at all, or they can move to a nonstandard probability theory
Autonomy Operating System for UAVs: Pilot-in-a-Box
The Autonomy Operating System (AOS) is an open flight software platform with Artificial Intelligence for smart UAVs. It is built to be extendable with new apps, similar to smartphones, to enable an expanding set of missions and capabilities. AOS has as its foundations NASAs core flight executive and core flight software (cFEcFS). Pilot-in-a-Box (PIB) is an expanding collection of interacting AOS apps that provide the knowledge and intelligence onboard a UAV to safely and autonomously fly in the National Air Space, eventually without a remote human ground crew. Longer-term, the goal of PIB is to provide the capability for pilotless air vehicles such as air taxis that will be key for new transportation concepts such as mobility-on-demand. PIB provides the procedural knowledge, situational awareness, and anticipatory planning (thinking ahead of the plane) that comprises pilot competencies. These competencies together with a natural language interface will enable Pilot-in-a-Box to dialogue directly with Air Traffic Management from takeoff through landing. This paper describes the overall AOS architecture, Artificial Intelligence reasoning engines, Pilot-in-a-box competencies, and selected experimental flight tests to date
An Efficient Java-Based Solver for Abstract Argumentation Frameworks: jArgSemSAT
Dung’s argumentation frameworks are adopted in a variety of applications, from
argument-mining, to intelligence analysis and legal reasoning. Despite this broad spectrum
of already existing applications, the mostly adopted solver—in virtue of its
simplicity—is far from being comparable to the current state-of-the-art solvers. On the
other hand, most of the current state-of-the-art solvers are far too complicated to be
deployed in real-world settings. In this paper we provide and extensive description of
jArgSemSAT, a Java re-implementation of ArgSemSAT. ArgSemSAT represents the best
single solver for argumentation semantics with the highest level of computational complexity.
We show that jArgSemSAT can be easily integrated in existing argumentation
systems (1) as an off-the-shelf, standalone, library; (2) as a Tweety compatible library;
and (3) as a fast and robust web service freely available on the Web. Our large experimental
analysis shows that—despite being written in Java—jArgSemSAT would have
scored in most of the cases among the three bests solvers for the two semantics with
highest computational complexity—Stable and Preferred—in the last competition on
computational models of argumentation
