CONVERGENCE of HUMANS and MACHINES project at the Faculty of Information Technology and Communication Sciences is looking for a Doctoral Researcher to work on the topic of Fairness and Explanations in Recommendations.

Convergence is the trailblazing doctoral field, aiming at bringing together expertise of natural sciences & engineering (ENG) and social sciences & humanities (SSH) in multidisciplinary union. As many as 16 doctoral research projects are related to the following developments: affective computing, gamification, augmented reality, cybernetics, ubiquitous connectivity, dispersed computing, AI & machine learning, and robotics & machine perception. Each student will be supervised by two leading senior faculty members (and, sometimes, a PostDoc or company/organization representative). The main supervisor and the co-supervisor are from different research fields: ENG and SSH. Check the end of the position description for the supervisory team details.

Convergence has 16 funded doctoral positions. The applicant may only apply for up to 3 positions within Convergence. If you are unsure if this (#14) is the correct one – please, check the website with the list of Convergence positions. Make your selection first and only apply the ones that are suitable for your background.

Project background

Convergence is a new research field that brings together academics from Social Sciences & Humanities and Technology & Engineering to train the next generation of Doctoral Expertise and address future challenges and opportunities of multidisciplinary Convergence of Humans and Machines. Convergence is funded by the Jane and Aatos Erkko Foundation.

Convergence is based on the premise that, on the one hand, people are increasingly integrated with technology and our culture and practices are increasingly dictated by information technology. On the other hand, machines are becoming more alive, creative, and dynamic. In other words, human and machine are converging. The project has emerged from the need to redefine and renegotiate the roles of human and machine in society and from the need of cross-disciplinary collaboration understand this rising area.

Job description

We are looking for a Doctoral Researcher in the area of AI & Machine Learning: Fairness, Bias, Explanations, Recommender Systems. To pursue the research towards “Fairness and Explanations in Recommendations” field.

Successful candidates will pursue a doctoral degree at Tampere University. Full-time doctoral studies are expected to be completed in four years.

An applicant may only apply for maximum 3 Convergence positions from this list. This position number is 14.

Short description:

Recommender systems (RS) is a category of AI systems that assist humans in making decisions, from harmless everyday life dilemmas to seemingly innocuous choices but with long-term, hidden consequences, up to more critical decisions. The prevalence of recommender systems in our lives gives rise to concerns about their trustworthiness. One mechanism to increase trust in recommendations is through explanations of the inner working of the system. Another means is to ensure the system exhibits desirable ethical traits, such as being non-discriminatory, diversity-aware, bias-free, which we collectively refer to as aspects of fairness. It is vital that the human user remains in the loop, able to interact with and control the behavior of the system in an accessible manner.

This doctoral research project focuses on studying and developing novel explainability methods that promote fairness and transparency in RS. We wish the student to focus on methods to (i) provide explanations capable of conveying fairness aspects, (ii) audit the system to examine fairness and discover latent source of bias via explanations, (iii) semi-automatically intervene to ensure system fairness, and (iv) interact with users to facilitate the above scenarios. The overall vision is to enable different stakeholders, such as RS providers, users (consumers, suppliers), and auditors, to query, understand, and fix sources of bias in RS, in an accessible, understandable, and transparent manner.

Tentative Research problems/questions:

Possible objectives of this doctoral position may include, but are not limited to, the following:

Objective 1. Fairness-aware explainability. The goal is to increase trust by providing fairness-specific explanations on the results of RS, as well as adaptively model the explanations to better convey the message to different user roles and groups.

Objective 2. Fairness correction. The goal is to provide the tools for unfairness discovery, assessment and correction, assisted via explainability and user interaction. An appropriate explanation engine might provide additional insight, indicating thus a bias in data. We envisage a system that effectively navigates the space of possible explanations to semi-automatically detect violations of fairness, that could not be manually recognized. Further, such a system decides on the appropriate fairness intervention approach based on fairness-aware explanations.

Objective 3. Interactive explanations. The goal is to design interactive methods for users to control, refine, adjust the explanation received, via means of follow-up explanations, and changes to fairness notions. A variety of visualization instruments will be developed, to satisfy different user roles and groups, while human-in-the-loop interaction will be supported towards optimizing the fairness and explainability processes.

Requirements

The applicant needs to have a Master's degree in Computer Science or a related field and have demonstrated (during your studies towards the Master's degree or otherwise) the competence and motivation to pursue postgraduate studies. Please be prepared to provide proof of your merits when requested.

    Summary in Finnish

    Tampereen yliopisto ja Tampereen ammattikorkeakoulu muodostavat yhdessä Suomen toiseksi suurimman monitieteisen, innostavan ja vaikuttavan tutkimus- ja oppimisyhteisön. Korkeakouluyhteisömme osaamiskärjet ovat tekniikka, terveys ja yhteiskunta. Lue lisää: www. tuni.fi

    ITC on käynnistänyt uuden monitieteisen tutkimussuunnan Ihmiset ja teknologiat -tohtoriohjelmaan (DPHAT) sijoittuvan CONVERGENCE – Ihmisen ja koneen konvergenssi -tutkimusalan puitteissa.

    Maailma on täyttymässä erilaisista koneista, autonomisista ajoneuvoista, reaaliaikaisista käännöstyökaluista, puettavasta teknologiasta ja muista laitteista, joissa ihmisen ja koneen välinen raja on katoamassa. Ihmisen ja koneen konvergenssi -ohjelman päätavoitteena onkin tutkia tulevaisuutta, jossa tietoa, asiantuntemusta ja taitoja voidaan siirtää reaaliajassa ja jossa tekoälyyn perustuvat toimijat ymmärtävät ja aistivat ihmistä reagoiden tähän ennakoiden ja eettisesti. Kehitys näyttää johtavan modernin ihmisen ja koneiden yhteistoimintaan ja rinnakkaiseloon eli konvergenssiin, joka tuo mukanaan täysin uusia tutkimusongelmia.

    Näiden haasteiden ratkaisemiseksi ITC-tiedekunta rekrytoi 16 palkkapaikallista väitöskirjatutkijaa. Jokaista opiskelijaa ohjaa pääohjaaja ja sivuohjaaja, jotka ovat eri aloilta (toinen yhteiskunta- ja humanistisista tieteistä ja toinen tekniikan alalta).

    Luodaan uutta eri alueet yhdistävää osaamista yhdessä!

    Tehtävänkuvaus

    Väitöskirjatutkija (Reiluus ja Selitykset Suosituksissa)

    Tämä tohtorin tutkimusprojekti pyrkii edistämään tutkimusta selitettävyyden, reiluuden ja käyttäjävuorovaikutuksen leikkauksessa suositusjärjestelmien alueella. Projekti suunnittelee menetelmiä, jotka (1) antavat selityksiä, jotka pystyvät välittämään reiluusominaisuuksia, (2) auditoivat järjestelmän reiluuden tarkastelua varten ja löytävät latentteja biaksen lähteitä selitysten kautta, ja (3) vuorovaikuttavat käyttäjien kanssa edistääkseen ja ohjatakseen edellämainittuja skenaarioita. Projekti kattaa eri sidosryhmien tarpeet, kuten suositusten kuluttajien, suositettavien aineistonäytteiden tuottajat/tuojat, ja järjestelmien omistajat, joilla voi olla vaihteleva kokemus ja asiantuntemus järjestelmästä ja allaolevista tekoälyteknologioista.
