To leverage the power of big data from source tasks and overcome the scarcity of the target task samples, representation learning based on multitask pretraining has become a standard approach in many applications. Each of the tasks would have one or more loss terms, and the total loss is generally a weighted average of all loss terms. …. Fig. Multi-task learning is a machine learning method in which a model learns to solve multiple tasks simultaneously. 2(b) is ordinary multitask learning, which is trained by the sum of task-specific losses, and Fig. 2(a) displays learning a single task, where individual networks learn through task-specific loss function.
