arXiv.org
Hallucinations in foundation models arise from autoregressive training objectives that prioritize token-likelihood optimization over epistemic accuracy, fostering overconfidence and poorly calibrated uncertainty.

A Foundation Theory of Evidence

SSRN Electronic Journal, 2010
This article argues that foundation, not relevance, embodies our fundamental understanding of admissible evidence. The foundation principle - only partially and somewhat obliquely stated in the Federal Rules of Evidence - is a requirement that evidence be case-specific, assertive and probably true.

Ethical Deliberation: A Foundation for Evidence-Based Practice

Seminars in Speech and Language, 2011
Infusing evidence-based practice (EBP) into the clinical setting implies that professionals use evidence that is relevant and credible, maintain their pursuit of best current knowledge, respect their clients' preferences and values, and keep these clients and their families appropriately informed about their treatment options.

Coherence, Foundations, and Evidence

1993
Abstract In this chapter, I (1) examine the contrast between foundationalism and coherentism, and (2) consider evidentialism, a special variety of foundationalism. After arguing that the central tenet of coherentism is that the sole source of warrant is coherence, I argue that coherentism is mistaken and endorse foundationalism.

Mathematical Foundations of Evidence Theory

1995
Reasoning schemes in artificial intelligence (and elsewhere) use information and knowledge, but the inference my depend on assumptions which are uncertain. In this case arguments in favour of and against hypotheses can be derived. These arguments may be weighed by their likelihoods and thereby the credibility and plausibility of different possible ...
