Open-world Machine Learning: Applications, Challenges, and Opportunities [article]

Jitendra Parmar, Satyendra Singh Chouhan, Santosh Singh Rathore
2021 arXiv   pre-print
Traditional machine learning especially supervised learning follows the assumptions of closed-world learning i.e., for each testing class a training class is available.  ...  Moreover, traditional machine learning is static learning which is not appropriate for an active environment where the perspective and sources, and/or volume of data are changing rapidly.  ...  NNO is a combination of two open-space risks for model combination and open-space risk for threshold space.  ...

Gray-box optimization and factorized distribution algorithms: where two worlds collide [article]

Roberto Santana
2017 arXiv   pre-print
The paper also elaborates on some of the questions that arise when extending the use of problem structure in EAs, such as the question of evolvability, high cardinality of the variables and large definition  ...  Finally, emergent approaches that exploit neural models to capture the problem structure are covered.  ...  Both the process of identifying those building blocks (learning), and the process of combining them by sampling, are two essential ingredients of the automatic method for problem decomposition as implemented  ...

GB-CENT

Qian Zhao, Yue Shi, Liangjie Hong
2017 Proceedings of the 26th International Conference on World Wide Web - WWW '17  
Since in real-world applications we usually have both abundant numerical features and categorical features with large cardinality (e.g. geolocations, IDs, tags etc.), we design a new model, called GB-CENT  ...  Latent factor models and decision tree based models are widely used in tasks of prediction, ranking and recommendation.  ...  [8] on combining wide and deep learning in recommender systems.  ...

Holistic aggregates in a networked world

Graham Cormode, Minos Garofalakis, S. Muthukrishnan, Rajeev Rastogi
2005 Proceedings of the 2005 ACM SIGMOD international conference on Management of data - SIGMOD '05  
In a nutshell, our algorithms employ a combination of local tracking at remote sites and simple prediction models for local site behavior in order to produce highly communication-and space-efficient solutions  ...  While traditional database systems optimize for performance on one-shot queries, emerging large-scale monitoring applications require continuous tracking of complex aggregates and data-distribution summaries  ...  , or even more sophisticated machine-learning techniques (e.g., linear or higher-order regression).  ...

The MVTec Anomaly Detection Dataset: A Comprehensive Real-World Dataset for Unsupervised Anomaly Detection

Paul Bergmann, Kilian Batzner, Michael Fauser, David Sattlegger, Carsten Steger
2021 International Journal of Computer Vision  
This benchmark indicates that methods that leverage descriptors of pretrained networks outperform all other approaches and deep-learning-based generative models show considerable room for improvement.  ...  We highlight the advantages and disadvantages of multiple performance metrics as well as threshold estimation techniques.  ...  For the more traditional methods, i.e., the Variation Model and the Texture Inspection Model, we use optimized implementations of the HALCON machine vision library that entirely run on the CPU and achieve  ...
