Treffer: Advanced Research on AI Algorithms for Supporting AI Constellation.

The following four examples of NTT's research on cutting-edge artificial intelligence (AI) algorithms to be used as basic techniques for AI Constellation--a large-scale AI collaboration technology--are introduced in this article: (i) "learning transfer," which enables the reuse of learning results; (ii) "transfer learning" that can adapt to environmental changes in imbalanced data with low labeling costs; (iii) "test-time-adaptation" for numerical-prediction models; and (iv) "sparse modeling" for analyzing a wide variety of large-scale, high-dimensional data.
