Machine learning with big labeled data has been actively investigated and its effectiveness has been demonstrated. However, in many application domains, it is difficult or even it is not possible to collect a large amount of labeled data. In the Imperfect Information Learning Team, for various machine learning tasks including supervised learning, unsupervised learning, and reinforcement learning, we develop novel algorithms that allow accurate learning from weakly-supervised data including partially labeled, high-dimensional, non-i.i.d., and extremely noisy data. We also elucidate their theoretical properties and apply them to various real-world applications ranging from fundamental science to business. The successful candidate is expected to develop algorithms of weakly-supervised learning, analyze theoretical properties, and perform experiments individually. Supervising interns and part-time students as well as supporting industry projects are also expected.
- must have a Ph.D. or expect to receive a Ph.D. before the date of employment in machine learning, computer science, statistics or a related field.
- must be proactive, cooperative, flexible, and able to respond according to the circumstances.
- must also have good communication skills and be able to cooperate with the relevant personnel within/outside of the laboratory to fulfill the tasks.
