Proactive assessment of computer-network vulnerability to unknown future attacks is an important but unsolved computer security problem where AI techniques have significant impact potential. In this paper, we investigate the use of reinforcement learning (RL) for proactive security in the context of denial-of-service (DoS) attacks in peer-to-peer (P2P) networks. Such a tool would be useful for ...

Given the increasing number of students registering to MOOCs for free, course instructors who want to go beyond automated evaluation have no choice but to use peer assessment. Despite the increasing use of peer evaluation, very little is known regarding the factors that influence assessors’ engagement in the process. Based on two editions of Introduction to Project Management, the first French ...

Learning analytics should go beyond data analysis and include approaches and algorithms that are meaningful for learner performance and that can be interpreted by teacher and related to learning outcomes. Assessment analytics has been lagging behind other research in learning analytics. This holds true especially for peer-assessment analytics. In this paper we present a mathematical model for p...

This work presents a novel method for modeling collaborative learning as multi-issue agent negotiation using fuzzy constraints. Agent negotiation is an iterative process, through which, the proposed method aggregates student marks to reduce personal bias. In the framework, students define individual fuzzy membership functions based on their evaluation concepts and agents facilitate student-stud...

Reputation assessment is particularly needed in peer-to-peer systems because peers can have conflicting interests and their autonomy is amplified by the inherent decentralization of the environment. However, the lack of centralization makes it more difficult to perform reputation assessment. Existing reputation systems tackle the reputation assessment process in an ad-hoc manner. In this thesis...

Peer bias is recognised as a primary factor in negative student perceptions of peer assessment strategies. This study trialled the use of classroom response systems, widely known as clickers, in small seminar classes in order to actively engage students in their subject’s assessment process while providing the anonymity that would lessen the impact of peer pressure. Focus group reflection on th...

The use of peer assessment through a multisource feedback process has gained recognition as a reliable and valid method to assess the characteristics of professionals and trainees. A total of 168 first-year medical students completed a 15-item questionnaire to self-assess their professional work habits and interpersonal abilities. Each student was expected to identify 8 first-year classmates to...
