AUCReshaping: improved sensitivity at high-specificity

open access: yesScientific Reports, 2023
The evaluation of deep-learning (DL) systems typically relies on the Area under the Receiver-Operating-Curve (AU-ROC) as a performance metric. However, AU-ROC, in its holistic form, does not sufficiently consider performance within specific ranges of ...

Palladium-catalysed formation of vicinal all-carbon quaternary centres via propargylation

open access: yesNature Communications, 2016
Formation of vicinal, quaternary stereocentres is challenging, but such products are commonly encountered in nature. Here, the authors report a palladium catalysed process to form vicinal quaternary carbons via propargylation, including in enantiopure ...

Redundant neural vision systems: competing for collision recognition roles [PDF]

open access: yes, 2013
Ability to detect collisions is vital for future robots that interact with humans in complex visual environments. Lobula giant movement detectors (LGMD) and directional selective neurons (DSNs) are two types of identified neurons found in the visual ...

Strongly Refuting Random CSPs Below the Spectral Threshold

open access: yes, 2016
Random constraint satisfaction problems (CSPs) are known to exhibit threshold phenomena: given a uniformly random instance of a CSP with $n$ variables and $m$ clauses, there is a value of $m = \Omega(n)$ beyond which the CSP will be unsatisfiable with ...

Face recognition technologies for evidential evaluation of video traces [PDF]

open access: yes, 2017
Human recognition from video traces is an important task in forensic investigations and evidence evaluations. Compared with other biometric traits, face is one of the most popularly used modalities for human recognition due to the fact that its ...

A framework for forensic face recognition based on recognition performance calibrated for the quality of image pairs [PDF]

open access: yes, 2012
Recently, it has been shown that performance of a face recognition system depends on the quality of both face images participating in the recognition process: the reference and the test image. In the context of forensic face recognition, this observation

Sparse self-attention aggregation networks for neural sequence slice interpolation

open access: yesBioData Mining, 2021
Background Microscopic imaging is a crucial technology for visualizing neural and tissue structures. Large-area defects inevitably occur during the imaging process of electron microscope (EM) serial slices, which lead to reduced registration and semantic

Exploring Misclassification Information for Fine-Grained Image Classification

open access: yesSensors, 2021
Fine-grained image classification is a hot topic that has been widely studied recently. Many fine-grained image classification methods ignore misclassification information, which is important to improve classification accuracy.

Rapid Interactive and Intuitive Segmentation of 3D Medical Images Using Radial Basis Function Interpolation

open access: yesJournal of Imaging, 2017
Segmentation is one of the most important parts of medical image analysis. Manual segmentation is very cumbersome, time-consuming, and prone to inter-observer variability. Fully automatic segmentation approaches require a large amount of labeled training

Monocular SLAM Supported Object Recognition [PDF]

open access: yes, 2015
In this work, we develop a monocular SLAM-aware object recognition system that is able to achieve considerably stronger recognition performance, as compared to classical object recognition systems that function on a frame-by-frame basis. By incorporating
