• Abstract summary: We identify two major related research fields, domain shift and concept drift. In this review, we regroup domain shift and concept drift into a single research problem, namely the data change problem. We propose a three-phase problem categorization scheme to link the key ideas in the two technical fields.

• Abstract: Recent artificial intelligence (AI) technologies show remarkable evolution in various academic fields and industries. However, in the real world, dynamic data lead to principal challenges for deploying AI models. An unexpected data change brings about severe performance degradation in AI models. We identify two major related research fields, domain shift and concept drift according to the setting of the data change. Although these two popular research fields aim to solve distribution shift and non-stationary data stream problems, the underlying properties remain similar which also encourages similar technical approaches. In this review, we regroup domain shift and concept drift into a single research problem, namely the data change problem, with a systematic overview of state-of-the-art methods in the two research fields. We propose a three-phase problem categorization scheme to link the key ideas in the two technical fields. We thus provide a novel scope for researchers to explore contemporary technical strategies, learn industrial applications, and identify future directions for addressing data change challenges.

  We develop a new learning paradigm named INTERN. By learning with supervisory signals from multiple sources in multiple stages, the model being trained will develop strong generalizability. In most cases, our models, adapted with only 10% of the training data in the target domain, outperform the counterparts trained with the full set of data.

  Lack of vision and clear objectives, a biased emphasis on technical issues, a low level of maturity for ad-hoc projects are among these challenges. Few methodologies offer a complete guideline across team, project and data & information management. We propose a conceptual framework containing general characteristics that a methodology for managing data science projects with a holistic point of view should have.
