With the proliferation of large pre-trained models in various domains, transfer learning has gained prominence where intermediate representations from these models can be leveraged to train better (target) task-specific models, with possibly limited labeled data. Although transfer learning can be beneficial in many applications, it can transfer undesirable information to target tasks that may severely curtail its performance in the target domain or raise ethical concerns related to privacy and/or fairness. In this paper, we propose a novel approach for suppressing the transfer of user-determined semantic concepts (viz. color, glasses, etc.) in intermediate source representations to target tasks without retraining the source model which can otherwise be expensive or even infeasible. Notably, we tackle a bigger challenge in the input data as a given intermediate source representation is biased towards the source task, thus possibly further entangling the desired concepts. We evaluate our approach qualitatively and quantitatively in the visual domain showcasing its efficacy for classification and generative source models. Finally, we provide a concept selection approach that automatically suppresses the undesirable concepts.

Exploiting Class Learnability in Noisy Data

  • Matthew Klawonn
  • Eric Heim
  • James Hendler

In many domains, collecting sufficient labeled training data for supervised machine learning requires easily accessible but noisy sources, such as crowdsourcing services or tagged Web data. Noisy labels occur frequently in data sets harvested via these means, sometimes resulting in entire classes of data on which learned classifiers generalize poorly. For real world applications, we argue that it can be beneficial to avoid training on such classes entirely. In this work, we aim to explore the classes in a given data set, and guide supervised training to spend time on a class proportional to its learnability. By focusing the training process, we aim to improve model generalization on classes with a strong signal. To that end, we develop an online algorithm that works in conjunction with classifier and training algorithm, iteratively selecting training data for the classifier based on how well it appears to generalize on each class. Testing our approach on a variety of data sets, we show our algorithm learns to focus on classes for which the model has low generalization error relative to strong baselines, yielding a classifier with good performance on learnable classes.

Computers Play Chess, Computers Play Go…Humans Play Dungeons & Dragons

  • Simon Ellis
  • James Hendler

With the AlphaGo computer program's recent win over one of the world's expert Go players, AI researchers need to explore new challenges in the game-playing arena. While there are a number of games to explore, the authors pose a true challenge for the next decade: attacking human-oriented games such as Dungeons & Dragons.

Semantic Data Representation for Improving Tensor Factorization

Predicting human activities is important for improving recommender systems or analyzing social relationships among users. Those human activities are usually represented as multi-object relationships (e. g. user’s tagging activities for items or user’s tweeting activities at some locations). Since multi-object relationships are naturally represented as a tensor, tensor factorization is becoming more important for predicting users’ possible activities. However, its prediction accuracy is weak for ambiguous and/or sparsely observed objects. Our solution, Semantic data Representation for Tensor Factorization (SRTF), tackles these problems by incorporating semantics into tensor factorization based on the following ideas: (1) It first links objects to vocabularies/taxonomies and resolves the ambiguity caused by objects that can be used for multiple purposes. (2) It next links objects to composite classes that merge classes in different kinds of vocabularies/taxonomies (e. g. classes in vocabularies for movie genres and those for directors) to avoid low prediction accuracy caused by rough-grained semantics. (3) It then lifts sparsely observed objects into their classes to solve the sparsity problem for rarely observed objects. To the best of our knowledge, this is the first study that leverages semantics to inject expert knowledge into tensor factorization. Experiments show that SRTF achieves up to 10% higher accuracy than state-of-the-art methods.

Society Online, Part 2 [Guest editors' introduction]

  • James Hendler
  • Wendy Hall

The Web is a critical global infrastructure. Since its emergence in the mid-1990s, it has exploded into hundreds of billions of pages that touch almost all aspects of modern life. Today the jobs of more and more people depend on the Web. Media, banking, and healthcare are being revolutionized by it, and governments are even considering how to run their countries with it.

Oliver G. Selfridge (1926-2008)

  • James Hendler

Oliver G. Selfridge, a leader in early artificial intelligence research, whose work extended from 1956 to 2008, recently passed away. His research in machine learning, neural networks and agent-based computing still influence AI today. He helped organize the 1956 Dartmouth summer school, which is generally seen as the origin of American AI and developed Pandemonium, an early AI program that dealt with learning and reasoning, during his more than 50-year career.

Reinventing Academic Publishing, Part 2

  • James Hendler

One possible model for scientific publishing is the overlay journal, which takes some interdisciplinary theme and provides links to papers published elsewhere. By providing links rather than republishing, the overlay journal provides a service to both the reader, by linking to many publications, and the publishers, by bringing more eyeballs to their sites.

The Dark Side of the Semantic Web

  • James Hendler

Many of the exciting and important things that are happening with the Semantic Web come from the Web side rather than the AI side. So, to many AI researchers, this part of the technology is unknown and is thus the "dark side" of the Semantic Web.

Commitment Strategies in Hierarchical Task Network Planning

  • Reiko Tsuneto
  • James Hendler

This paper compares three commitment strategies for HTN planning: (1) a strategy that delays variable bindings as much as possible; (2) a strategy in which no non-primitive task is expanded until all variable constraints are committed; and (3) a strategy that chooses between expansion and variable instantiation based on the number of branches that will be created in the search tree. Our results show that while there exist planning domains in which the first two strategies do well, the third does well over a broader range of planning domains.
