Fifth International Workshop on Experimental Economics and Machine Learning (EEML 2019)

Workshop concentrates on an interdisciplinary approach to modelling human behavior incorporating data mining and expert knowledge from behavioral sciences. Data analysis results extracted from clean data of laboratory experiments will be compared with noisy industrial datasets from the web e.g. Insights from behavioral sciences will help data scientists. Behavior scientists will see new inspirations to research from industrial data science. Market leaders in Big Data, as Microsoft, Facebook, and Google, have already realized the importance of experimental economics know-how for their business. 

In Experimental Economics, although financial rewards restrict subjects preferences in experiments, exclusive application of analytical game theory is not enough to explain the collected data. It calls for the development and evaluation of more sophisticated models. The more data is used for evaluation, the more statistical significance can be achieved. Since large amounts of behavioral data are required to scan for regularities, along with automated agents needed to simulate and intervene in human interactions, Machine Learning is the tool of choice for research in Experimental Economics. This workshop is aimed at bringing together researchers from both Data Analysis and Economics in order to achieve mutually beneficial results.

Title: Field Experimentation in Marketing Research
Abstract: Despite increasing efforts to encourage the adoption of field experiments in marketing research (e.g., Campbell 1969; Cialdini 1980; Li et al. 2015), the majority of scholars continue to rely primarily on laboratory studies (Cialdini 2009). For example, of the 50 articles published in Journal of Marketing Research in 2013, only three (6%) were based on field experiments. The goal of this article is to motivate a methodological shift in marketing research and increase the proportion of empirical findings obtained using field experiments. The author begins by making a case for field experiments and offers a description of their defining features. She then demonstrates the unique value that field experiments can offer and concludes with a discussion of key considerations that researchers should be mindful of when designing, planning, and running field experiments.

Dr. Gneezy's research has been published in leading academic journals, including Science, PNAS, the Journal of Marketing Research, Marketing Science, the Journal of Personality and Social Psychology, and the Journal of Consumer Research, and was featured by top media outlets such as The Wall Street Journal, The New York Times, Scientific American, The Huffington Post, and The Atlantic.

Her research addresses a wide variety of questions pertaining to consumer behavior such as behavioral pricing, prosocial behavior & charitable giving, social preferences (e.g., promise accounting, negative reciprocity, fairness), and factors affecting individuals’ quality of life. In her research, Dr. Gneezy collaborates with both small (e.g., a local winery) and large (e.g., Disney) firms and organizations, allowing her to conduct field experiments and test her predictions in “the wild.”

She is the co-founder and faculty director of the Rady School of Management’s US-Israel on Innovation & Economic Sustainability (USIC), and the Center for Social Innovation & Impact (CSII).

Vasily A. Leksin, Unit Leader in Recommender Systems, AVITO.ru, Moscow
Title: Recommender Systems for online classified advertisements
Abstract: I’ll tell about our journey from simple linear models to neural networks in the development of Recommender Systems in Avito and the current recommendations architecture. I will share successes and failures in building a highly loaded Recommendation Systems. We will discuss the gap between the latest scientific approaches and methods applicable in production systems and why we claim that the “keep it simple” principle works well in production systems.

Since 2013 Vasily Leksin has been working at AVITO.ru. Up to 2016, Vasily held a position of Lead Analyst. He was responsible for building and leading Antifraud team. Since 2016 Vasily performs as a Unit Leader in Recommender Systems. The team of talented Data Science professionals, Vasily leads, took 3’d place of 112 at RecSys Challenge 2018. Recommender systems generate significant share (roughly 30%) of Avito app buyers activity now.

He graduated in 2007 as a “Master of Applied Mathematics and Physics” at the “Moscow Institute of Physics and Technology” (Russia, Moscow). In 2012 he obtained his degree of “Candidate of Physico-Mathematical Sciences” (the equivalent of PhD) at the “Dorodnicyn Computing Centre of RAS”, Ph.D. thesis: "Stochastic models in customer environment analysis".

The most recent Vasily’s scientific publications in a field of recommender systems are:

• A hybrid two-stage recommender system for automatic playlist continuation which has been published in RECSYS CHALLENGE'18: PROCEEDINGS OF THE ACM RECOMMENDER SYSTEMS CHALLENGE 2018
• Combination of Content-Based User Profiling and Local Collective Embeddings for Job Recommendation. V. Leksin, A. Ostapets, M. Kamenshikov, D. Khodakov, V. Rubtsov. Published in: CEUR Workshop Proceeding, Vol. 1968, No. Experimental Economics and Machine Learning, 2017
