  "content": "<p>Hello Isabelle</p>\r\n<p>I was wondering what approach is relevant to this problem. Assume that we have solved the problem of action segmentation. What we then have is a master dataset which consists of multiple data sets (one per user) each with a limited amount of data (~150 labeled\r\n data points per user. I have considered all the segmented action videos). The aim is to learn a classifier for each of these small datasets such that every new classifier learns from the entire data set or from the previous classifiers. In the end we have\r\n a system that can churn out a classifier given just one data point per label for a new classifier.</p>\r\n<p>Have I summarized the problem correctly? I am not aware of what Machine Learning frameworks are there to address this kind of a problem. The closest is Transfer Learning. Can you please give me some hints on how you would approach this problem and what Machine\r\n learning frameworks might be applied to solve this problem. I am not interested in the competetion as much as in the Machine Learning framework. Thank you for providing the data and also answering all the questions so far.</p>\r\n<p>Regards</p>\r\n<p>Hemanth</p>",
