Automated essay scoring using efficient transformer-based language models
Christopher M Ormerod, Akanksha Malhotra, Amir Jafari
Automated Essay Scoring (AES) is a cross-disciplinary effort involving Education, Linguistics, and Natural Language Processing (NLP). The efficacy of an NLP model in AES tests it a…
Language models and Automated Essay Scoring
Pedro Uria Rodriguez, Amir Jafari, Christopher M. Ormerod
In this paper, we present a new comparative study on automatic essay scoring (AES). The current state-of-the-art natural language processing (NLP) neural network architectures are…
Neural network approach to classifying alarming student responses to online assessment
Christopher M. Ormerod, Amy E. Harris
Automated scoring engines are increasingly being used to score the free-form text responses that students give to questions. Such engines are not designed to appropriately deal wit…
An elliptic Garnier system
Christopher M. Ormerod, Eric M. Rains
We present a linear system of difference equations whose entries are expressed in terms of theta functions. This linear system is singular at points for , which a…
A symmetric difference-differential Lax pair for Painlevé VI
Christopher M. Ormerod, Eric M. Rains
We present a Lax pair for the sixth Painlevé equation arising as a continuous isomonodromic deformation of a system of linear difference equations with an additional symmetry struc…
Commutation Relations and Discrete Garnier Systems
Christopher M. Ormerod, Eric M. Rains
We present four classes of nonlinear systems which may be considered discrete analogues of the Garnier system. These systems arise as discrete isomonodromic deformations of systems…
