A neural network model of hippocampal contributions to category learning

open access: yeseLife, 2023
In addition to its critical role in encoding individual episodes, the hippocampus is capable of extracting regularities across experiences. This ability is central to category learning, and a growing literature indicates that the hippocampus indeed makes

Accessible Model Categories [PDF]

open access: yesApplied Categorical Structures, 2015
We prove that a weak factorization system on a locally presentable category is accessible if and only if it is small generated in the sense of R. Garner. Moreover, we discuss an analogy of Smith's theorem for accessible model categories.

The Flow Matrix Offers a Straightforward Alternative to the Problematic Markov Matrix

open access: yesLand, 2023
The Flow matrix is a novel method to describe and extrapolate transitions among categories. The Flow matrix extrapolates a constant transition size per unit of time on a time continuum with a maximum of one incident per observation during the ...

On the Left Properness of the Model Category of Permutative Categories

open access: yesAxioms, 2023
In this paper, we introduce a notion of free cofibrations of permutative categories. We show that each cofibration of permutative categories is a retract of a free cofibration.

Categories and range effects in human spatial memory

open access: yesFrontiers in Psychology, 2010
After learning a particular target stimulus, such as a location, humans’ judgements of whether a particular stimulus is the target or not is affected by the range of stimuli presented on tests.

Polynomial Columns-Parameter Symmetry Model and its Decomposition for Square Contingency Tables

open access: yesStatistica, 2021
This study proposes a polynomial columns-parameter symmetry model for square contingency tables with the same row and column ordinal classifications. In the proposed model, the odds for all i < j that an observation will fall in row category i and column

Sheafifiable homotopy model categories [PDF]

open access: yesMathematical Proceedings of the Cambridge Philosophical Society, 2000
If a Quillen model category can be specified using a certain logical syntax (intuitively, ``is algebraic/combinatorial enough''), so that it can be defined in any category of sheaves, then the satisfaction of Quillen's axioms over any site is a purely formal consequence of their being satisfied over the category of sets.
