How VADER is your AI? Towards a definition of artificial intelligence systems appropriate for regulation

no code implementations7 Feb 2024 Leonardo C. T. Bezerra, Alexander E. I. Brownlee, Luana Ferraz Alvarenga, Renan Cipriano Moioli, Thais Vasconcelos Batista

Our online, publicly-available VADER framework scores the coverage of premises that should underlie AI definitions for regulation, which aim to (i) reproduce principles observed in other successful technology regulations, and (ii) include all AI techniques and approaches while excluding non-AI works.

Detection of a facemask in real-time using deep learning methods: Prevention of Covid 19

no code implementations28 Jan 2024 Gautam Siddharth Kashyap, Jatin Sohlot, Ayesha Siddiqui, Ramsha Siddiqui, Karan Malik, Samar Wazir, Alexander E. I. Brownlee

By the end of April 2021, the world has recorded 144, 358, 956 confirmed cases of novel-coronavirus disease (Covid-19) including 3, 066, 113 deaths according to the world health organization (WHO).

From Simulations to Reality: Enhancing Multi-Robot Exploration for Urban Search and Rescue

no code implementations28 Nov 2023 Gautam Siddharth Kashyap, Deepkashi Mahajan, Orchid Chetia Phukan, Ankit Kumar, Alexander E. I. Brownlee, Jiechao Gao

In this study, we present a novel hybrid algorithm, combining Levy Flight (LF) and Particle Swarm Optimization (PSO) (LF-PSO), tailored for efficient multi-robot exploration in unknown environments with limited communication and no global positioning information.

Enhancing Genetic Improvement Mutations Using Large Language Models

no code implementations18 Oct 2023 Alexander E. I. Brownlee, James Callan, Karine Even-Mendoza, Alina Geiger, Carol Hanna, Justyna Petke, Federica Sarro, Dominik Sobania

We find that the number of patches passing unit tests is up to 75% higher with LLM-based edits than with standard Insert edits.

Roulette-Wheel Selection-Based PSO Algorithm for Solving the Vehicle Routing Problem with Time Windows

no code implementations4 Jun 2023 Gautam Siddharth Kashyap, Alexander E. I. Brownlee, Orchid Chetia Phukan, Karan Malik, Samar Wazir

The well-known Vehicle Routing Problem with Time Windows (VRPTW) aims to reduce the cost of moving goods between several destinations while accommodating constraints like set time windows for certain locations and vehicle capacity.

Towards Explainable Metaheuristic: Mining Surrogate Fitness Models for Importance of Variables

no code implementations31 May 2022 Manjinder Singh, Alexander E. I. Brownlee, David Cairns

Through mining the surrogate model we can build a picture of the learning process of a GA, and thus an explanation of the solution presented by the GA.

Metaheuristics "In the Large"

no code implementations19 Nov 2020 Jerry Swan, Steven Adriaensen, Alexander E. I. Brownlee, Kevin Hammond, Colin G. Johnson, Ahmed Kheiri, Faustyna Krawiec, J. J. Merelo, Leandro L. Minku, Ender Özcan, Gisele L. Pappa, Pablo García-Sánchez, Kenneth Sörensen, Stefan Voß, Markus Wagner, David R. White

We describe our vision and report on progress, showing how the adoption of common protocols for all metaheuristics can help liberate the potential of the field, easing the exploration of the design space of metaheuristics.
