This page contains information about the members and collaborators with the DSRS group, along with students doing exciting R&D projects with us.

Our Lab is part of a larger research group: Bristol’s Intelligent Systems Lab. Our research aims at investigating how multi-criteria and consensus decision making, information fusion, uncertainty handling and intelligent techniques can help supporting contemporary complex decision scenarios. Major questions currently being addressed include: (i) how to support consensual decision-making among large groups of participants, (ii) how to intelligently fuse disparate social and contextual data to improve personalization services via RecSys (Recommender Systems), and (iii) exploring novel applications of RecSys and decision support under uncertainty, such as: management sciences, tourism, academic recruitment and human-machine decision making.

Iván is a Lecturer – Assistant Professor – in Data Science and AI with the Department of Computer Science at UoB. He is also a Turing Fellow with the Alan Turing Institute, and an ACM Professional Member. His main research interests and current activities revolve around the following topics/problems:

  • Recommender Systems: Multi-View Data Fusion Strategies, Group Recommender Systems and Applications (tourism, leisure, smart cities, digital health…)
  • Decision Making under Uncertainty (predominantly of fuzzy and linguistic nature).
  • Multi-Criteria, Collective and Consensus-driven Decision Making.
  • Intelligent Decision Support Systems
  • Preference Modelling and Intelligent Aggregation Methods.
  • Collaborative Planning and Decision-Making with Autonomous Intelligent Systems.
  • Applications of Fuzzy Decision Making and Aggregation (autonomous systems, cyber-security, energy planning, …)

    Hello visitor! My name is Ercan, a PhD candidate at the University of Bristol. My main research area is investigating intelligent fusion techniques and context-aware recommender systems to provide personalised recommendation for tourists spending their leisure time in smart cities. My academic supervisor is Dr Ivan Palomares Carrascosa who is a great supporter of my work that blends a lot of experience both from his side and my side in the freshly established DSRS research group.

    Digital devices have always been my toys since my childhood. Whenever I saw a problem with them, I would spent hours to find a solution. This motivated me to become a Software Engineer to tackle up-to-date problems in both industry and academia. I worked for 3 years in the industry and now pursuing a career in academia.

    My educational background includes two bachelor degrees(Computer Education and Instructional Technologies, a double major in Software Engineering) at the Bahçeşehir University, in Turkey. I spent 6 months at EPITA , Paris as an exchange student. Finally, I received an MSc in Adv Computer Science at the University of Essex before I started my PhD.

    My name is James Neve, a PhD candidate at the University of Bristol in the DSRS Group, specialising in Reciprocal Recommender Systems. I have a BSc and MA in Computer Science from the University of Cambridge. Other research interests include decision systems and practical applications of machine learning, especially in the online dating field.

    Between graduating and starting my PhD, I spent 6 years in Japan working as a software developer, most recently for Eureka, part of Match Group and developer of the largest online dating service in Japan, Pairs. I am fluent in Japanese (JLPT N1 – highest level qualification) and experienced in writing large-scale applications in Go, Scala, Ruby, PHP and Python, setting up AWS architecture with Terraform and Packer and various database technologies including SQL, NoSQL and cache services such as Redis and Memcached.

    I am interested in Japanese language and culture. I also play bass guitar, know a lot about heavy metal music and I’m interested in powerlifting and strongman.

Hello! If you are reading this, it is because you are curious about me (or probably you have clicked wrongly). I am a PhD candidate at the University of Bristol in the Decision Support and Recommender Systems research Group. A lifelong interest in technology led me to study and earn a bachelor’s degree in Computer Engineering. Afterwards, I completed a master’s degree in Science and Computer Engineering, focused in Artificial Intelligence by National Autonomous University of Mexico (UNAM).
My research fields are Evolutionary Computing (mainly Genetic Algorithms and Genetic Programming) and Machine Learning (supervised learning). I have applied these techniques to solve problems related to logistic processes. For instance, I developed a computacional entity which is capable of finding a way to arrange merchandise in a transport vehicle considering restrictions such as product weight, physical dimensions of the vehicle and product compatibilities. Furthermore, I have worked in a project which consisted in using the output of the project mentioned previously to train a learning algorithm which objective consists in suggesting a set of ways to arrange products in a transport vehicle.
Although it seems I cannot do anything different related to computers, I like to make music; I play drums and when it is possible, I like running and I like reading; Science Fiction is my favorite genre. Moreover, I am vegetarian.

My research interests are concerned with decision analysis under uncertainty and soft aggregation processes – broadly falling into the area of computational mathematics. My major foci are: i) fuzzy set theory and higher order fuzzy sets such as intuitionistic fuzzy set, type-2 fuzzy set, hesitant fuzzy set, neutrosophic set, bipolar fuzzy set, conflicting bifuzzy set and imprecise probability theory such as Dempster-Shafer theory of evidence; ii) decision analysis models under multidimensional aspect such as additive and multiplicative preference relation models, outranking relation models, cardinal-based decision models; iii) aggregation operators for information fusion involving dependency and independency among data or arguments. The classical arithmetic means and ordered weighted average are among the independency type of aggregation operators. This also holds for the weighted and the generalized versions of these operators. Moreovthe er, dependency type of aggregation operators is based on fuzzy measure such as choquet integral and sugeno integral. The integration of the above-mentioned techniques can produce more sophisticated decision-making models that deal with complex decision analysis of real-world problem. Current research interest is on the inclusion of human perception in decision analysis, including the consideration of human behaviour or preference between two extreme cases; pessimistic to optimistic points of view. My current contribution is on the integration of soft aggregation processes based on majority concept for the multi-expert decision-making models. Ordered weighted average and its variants as well as the concept of fuzzy set theory play their role in expanding and generalizing the classical models. Recently, the developed models have been applied and tested in the financial analysis domain.
