Structurally corrected invariant-preserving neural networks for conservative dynamical systems: a statistically validated approach

open access: yesScientific Journal of King Faisal University: Basic and Applied Sciences
In this paper a structural correction in neural network architecture for the long-time integration of conservative dynamical systems is used to overcome uncontrolled invariant drift existing in standard physics-informed formulations.

Direct and Indirect Effects of IQ, Parental Help, Effort, and Mathematics Self-Concept on Mathematics Achievement

open access: yesEurope's Journal of Psychology, 2012
This study examined the structural relationships among cognitive constructs (intelligence and achievement) and affective constructs (perceived parental help, effort and self-concept). It was proposed that the relationships are not invariant across gender.

ML-MIFD: Multi-Level Multimodal Invariant Feature Descriptor [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Existing cross-modal feature descriptors are typically limited to single-level local statistics, leading to insufficient structural representation and degraded matching performance under nonlinear radiometric differences and strong noise. To address this

Visual Odometry Based on Structural Matching of Local Invariant Features Using Stereo Camera Sensor

open access: yesSensors, 2011
This paper describes a novel sensor system to estimate the motion of a stereo camera. Local invariant image features are matched between pairs of frames and linked into image trajectories at video rate, providing the so-called visual odometry, i.e ...
