Recent Advances in Open Set Recognition: A Survey
Geng, Chuanxing, Huang, Sheng-jun, Chen, Songcan
In real-world recognition/classification tasks, limited by various objective factors, it is usually difficult to collect training samples to exhaust all classes when training a recognizer or classifier. A more realistic scenario is open set recognition (OSR), where incomplete knowledge of the world exists at training time, and unknown classes can be submitted to an algorithm during testing, requiring the classifiers not only to accurately classify the seen classes, but also to effectively deal with the unseen ones. This paper provides a comprehensive survey of existing open set recognition techniques covering various aspects ranging from related definitions, representations of models, datasets, experiment setup and evaluation metrics. Furthermore, we briefly analyze the relationships between OSR and its related tasks including zero-shot, one-shot (few-shot) recognition/learning techniques, classification with reject option, and so forth. Additionally, we also overview the open world recognition which can be seen as a natural extension of OSR. Importantly, we highlight the limitations of existing approaches and point out some promising subsequent research directions in this field.
The business LMS โ from basic requirement to learning ecosystem MATRIX Blog
Learning management systems are not new to corporate learning; they have been around for quite some time and each year more and more are released. What an LMS basically does is host, distribute, record and report on all learning that goes on within an organization. Apart from that, there are many more additional features that companies ask for and expect today. Probably the most difficult one to incorporate is tracking all informal learning and using the information to provide highly personalized learning. The LMS is the critical component to the entire e-learning program, acting both as the foundation (by incorporating all the modules) and as the engine (by providing the environment in which learners can access them and suggesting various topics based on curriculum and personal interest).
Miyazaki finds solution to IT labor crunch thousands of kilometers away
MIYAZAKI โ Like many of Japan's smaller cities, Miyazaki has been hit by a growing labor crunch, a trend highlighted by the mere 56.8 percent of high school graduates that chose to remain in the prefecture to work -- the third worst among the country's 47 prefectures. In the hard-hit information technology sector, the city has been encouraging firms to run businesses there to help energize the area, said Tsugunobu Ogino, president of KJS Co., a Miyazaki-based IT firm that makes e-learning systems. "But they are struggling to find engineers, since many move to Tokyo," he said. Now, the city in the southern Kyushu region may have found an unexpected solution, one thousands of kilometers away: Bangladesh. The South Asian nation faces a scenario that is almost the complete inverse of Japan -- there are simply not enough jobs for its ample working population.

On Training Recurrent Neural Networks for Lifelong Learning
Sodhani, Shagun, Chandar, Sarath, Bengio, Yoshua
Lifelong Machine Learning considers systems that can learn many tasks (from one or more domains) over a lifetime (Thrun, 1998; Silver et al., 2013). This has several names and manifestations in the literature: incremental learning (Solomonoff, 1989), continual learning (Ring, 1997), explanation-based learning (Thrun, 1996, 2012), never ending learning (Carlson et al., 2010), etc. The underlying idea motivating these efforts is the following: Lifelong learning systems would be more effective at learning and retaining knowledge across different tasks. By using the prior knowledge and exploiting similarity acrosstasks, they would be able to obtain better priors for the task at hand. Lifelong learning techniques are very important for training intelligent autonomous agents that would need to operate and make decisions over extended periods of time. These characteristics arespecially important in the industrial setups where the deployed machine learning models are being updated frequently with new incoming data whose distribution neednot match the data on which the model was originally trained. Lifelong learning is an extremely challenging task for the machine learning models because of two primary reasons: 1. Catastrophic Forgetting: As the model is trained on a new task (or a new data/task distribution), it is likely to forget the knowledge it acquired from the previous tasks (or data distributions). This phenomenon is also known as the catastrophic interference (McCloskey and Cohen, 1989).
The Barbados 2018 List of Open Issues in Continual Learning
Schaul, Tom, van Hasselt, Hado, Modayil, Joseph, White, Martha, White, Adam, Bacon, Pierre-Luc, Harb, Jean, Mourad, Shibl, Bellemare, Marc, Precup, Doina
We want to make progress toward artificial general intelligence, namely general-purpose agents that autonomously learn how to competently act in complex environments. The purpose of this report is to sketch a research outline, share some of the most important open issues we are facing, and stimulate further discussion in the community. The content is based on some of our discussions during a weeklong workshop held in Barbados in February 2018. We adopt the reinforcement learning (RL) formulation, where an agent interacts sequentially with an environment, and the agent is provided a reward signal that unambiguously defines success. We want to explicitly consider some of the most challenging dimensions for a developing intelligence.

In this tutorial, I assume that you're already familiar with Scikit-learn, Pandas, NumPy, and SciPy. These packages are important prerequisites for this tutorial. Deep learning is a subfield of machine learning with algorithms inspired by the working of the human brain.
Knowledge Tracing Machines: Factorization Machines for Knowledge Tracing
Vie, Jill-Jรชnn, Kashima, Hisashi
Knowledge tracing is a sequence prediction problem where the goal is to predict the outcomes of students over questions as they are interacting with a learning platform. By tracking the evolution of the knowledge of some student, one can optimize instruction. Existing methods are either based on temporal latent variable models, or factor analysis with temporal features. We here show that factorization machines (FMs), a model for regression or classification, encompasses several existing models in the educational literature as special cases, notably additive factor model, performance factor model, and multidimensional item response theory. We show, using several real datasets of tens of thousands of users and items, that FMs can estimate student knowledge accurately and fast even when student data is sparsely observed, and handle side information such as multiple knowledge components and number of attempts at item or skill level. Our approach allows to fit student models of higher dimension than existing models, and provides a testbed to try new combinations of features in order to improve existing models.
