One of the major challenges for negative selection is to efficiently generate effective detectors. The experiment in the past shows that random generation fails to generate useful detectors within acceptable time duration. In this paper, we propose an antigen feedback mechanism for generating the detectors. For an unmatched antigen, we make a copy of the antigen and treat it the same as a newly...

This paper describes the design and evaluation of two features in an Intelligent Tutoring System designed to facilitate a deeper conceptual understanding of domain principles in conjunction with the development of procedural skills. The first feature described here relates to the timing of feedback. Some researchers have argued that immediate corrective feedback, as embodied in many cognitive t...

We classify all pairs (G, V ) with G a closed subgroup in a classical group G with natural module V over C, such that G and G have the same composition factors on V ⊗k for a fixed k ∈ {2, 3, 4}. In particular, we prove Larsen’s conjecture stating that for dim(V ) > 6 and k = 4 there are no such G aside from those containing the derived subgroup of G. We also find all the examples where this fai...

The goal of our work is the design and implementation of a virtual agents based interactive simulation for teaching and training health care workers in the proper procedures for hand hygiene. The health care trainee in the simulation plays the role of a health care inspector in a virtual hospital that resembles a real hospital. The interactive training simulation features a virtual instructor w...

Feedback into the broader policy debate in macroeconomic and related structural areas remains limited. However, when a more informed debate and broadening of the policy space did take place on these issues, the policy outcome was generally positive. In contrast, when controversial issues involving difficult trade-offs were avoided during the PRS process, the consequences for “downstream” polici...

BACKGROUND This article outlines procedures for the feedback of individual research data to participants. This feedback framework was developed in the context of a personalized medicine research project in Canada. Researchers in this domain have an ethical obligation to return individual research results and/or material incidental findings that are clinically significant, valid and actionable t...

Feature Selection in very-high-dimensional or small sample problems is particularly prone to computational and robustness complications. It is common to resort to feature ranking approaches only or to randomization techniques. A recent novel approach to the randomization idea in form of Dependency-Aware Feature Ranking (DAF) has shown great potential in tackling these problems well. Its origina...

We examined how feedback delay and stimulus offset timing affected declarative, rule-based and procedural, information-integration category-learning. We predicted that small feedback delays of several hundred milliseconds would lead to the best information-integration learning based on a highly regarded neurobiological model of learning in the striatum. In Experiment 1 information-integration l...

Considerable interest in the hypothesis that different cognitive tasks recruit qualitatively distinct processing systems has led to the proposal of separate explicit (declarative) and implicit (procedural) systems. A popular probabilistic category learning task known as the weather prediction task is said to be ideally suited to examine this distinction because its two versions, "observation" a...

This paper presents the framework of a scale-oriented scheme for the presentation and classification of reverse engineered sections of procedural code into objects. The aim is to develop an extensible system framework, which allows the output from a suite of data analysis tools to be visually presented to a user. The relationship between the analysis and visualisation is a progressive cycle, wh...
