Users are dissatisfied with services. Since the service is not tailor-made for a user, it is natural for dissatisfaction to arise. The problem is, that even if users are dissatisfied, they often do not have the means to resolve their dissatisfaction. The user cannot alter the source code of the service, nor can they force the service provider to change. The user has no choice but to remain dissatisfied or quit the service. User-side realization offers proactive solutions to this problem by providing general algorithms to deal with common problems on the user's side. These algorithms run on the user's side and solve the problems without having the service provider change the service itself.

Google recently released research about a tool called Similar Medical Images Like Yours (SMILY) that uses concept vectors to enhance searching for medical images. The research uses embeddings for image-based search and allows users to influence the search through the interactive refinement of concepts. Google released two papers in succession. The first paper, "Similar image search for histopathology: SMILY" focused on the deep neural network architecture that was used to create the embeddings necessary to find similar images. The second paper, "Human-Centered Tools for Coping with Imperfect Algorithms During Medical Decision-Making," focused on human interaction aspects necessary to improve the usage of the tool created in the first paper.
