Yujie Lin, Pengjie Ren, Zhumin Chen, Zhaochun Ren, Jun Ma, and I published “Explainable Fashion Recommendation with Joint Outfit Matching and Comment Generation” on arXiv. Most previous work on fashion recommendation focuses on designing visual features to enhance recommendations. Existing work neglects user comments of fashion items, which have been proved effective in generating explanations…
Five more vacancies for fully funded PhD students
We just opened five more vacancies for PhD students. The general area is AI for Retail, and the positions are part of the new AIRLab. Areas range from recommendation to federated search and conversational search to replenishment. Deadline: July 16, 2018. Please visit this page for all the details.
Three more papers on arXiv
We’ve just put three more papers on arXiv. Earlier in June, Sapna Negi, Paul Buitelaar, and I put “Open Domain Suggestion Mining: Problem Definition and Datasets” on arXiv. In the paper we propose a formal definition for the task of suggestion mining in the context of a wide range of open domain applications. Human perception…
Another IR vacancy
We just opened another vacancy, for a PhD student to work on dataset search. Come and join us to work in the area of AI & IR, together with great colleagues at Elsevier, VU Amsterdam and KNAW. See https://t.co/um5ldIQAZg for more details.

Hello World: Innovation Center for Artificial Intelligence
Yesterday, ICAI, the national Innovation Center for Artificial Intelligence, was launched. ICAI is a national initiative focused on joint technology development between academia and industry in the area of artificial intelligence. Artificial intelligence (AI) has become a key technology that is rapidly becoming a disruptor for all economic sectors. Given the impact, AI also generates…
Now on arXiv: Finding influential training samples for gradient boosted decision trees
Boris Sharchilev, Yury Ustinovsky, Pavel Serdyukov, and I have released a new pre-print on “finding influential training samples for gradient boosted decision trees” on arXiv. In the paper we address the problem of finding influential training samples for a particular case of tree ensemble-based models, e.g., Random Forest (RF) or Gradient Boosted Decision Trees (GBDT)….
Now on arXiv: Optimizing interactive systems with data-driven objectives
Ziming Li, Artem Grotov, Julia Kiseleva, Harrie Oosterhuis and I have just released a new preprint on “optimizing interactive systems with data-driven objectives” on arXiv. Effective optimization is essential for interactive systems to provide a satisfactory user experience. However, it is often challenging to find an objective to optimize for. Generally, such objectives are manually…
ICLR 2018 paper on Deep Learning with Logged Bandit Feedback online now
“Deep Learning with Logged Bandit Feedback” by Thorsten Joachims, Adith Swaminathan and Maarten de Rijke, to be published at ICLR 2018, is available online. In the paper we propose a new output layer for deep neural networks that permits the use of logged contextual bandit feedback for training. Such contextual bandit feedback can be available…
