Brave Induction
This paper considers the following induction problem. Given the background knowledge B and an observation O, find a hypothesis H such that a consistent theory B ∧ H has a minimal model satisfying O. We call this type of induction brave induction. Brave induction is different from explanatory induction in ILP, which requires that O is satisfied in every model of B ∧ H. Brave induction is useful ...
متن کاملHonest Computability and Complexity
Computations manipulate representations of objects, most often strings of symbols taken from some finite alphabet, rather than the objects themselves. Numbers, for example, are usually denoted by sequences of decimal, or binary, or unary digits. In logic, one therefore distinguishes between numbers n, which reside in an ideal Platonic world, and numerals ⌜n⌝, their symbolic representation as (f...
متن کاملDora the Brave.
I f you notice any particularly fidgety journal editors this month don’t worry—this is merely a symptom of the imminent release of the next round of the dreaded, dreadful Journal Impact Factors (JIFs). Editors are concerned, because the JIF directly impacts their journal, as it influences if researchers choose it to publish their research. JIF has a number of flaws, but one entirely outside an ...
متن کاملEntropy? Honest!
Here we deconstruct, and then in a reasoned way reconstruct, the concept of “entropy of a system”, paying particular attention to where the randomness may be coming from. We start with the core concept of entropy as a count associated with a description; this count (traditionally expressed in logarithmic form for a number of good reasons) is in essence the number of possibilities—specific insta...
متن کاملHonest universality.
We extend the notion of universality of a function, due to Turing, to arbitrary (countable) effective domains, taking care to disallow any cheating on the part of the representations used. Then, we can be certain that effective universal functions cannot simulate non-effective functions.
