Abstract: Multi-Task Learning (MTL) is a neural network design paradigm that aims to improve generalization while simultaneously solving multiple tasks. It has obtained success in many application areas such as Natural Language Processing and Computer Vision. In an MTL neural network, there are shared task branches and task-specific branches. However, automatically deciding on the best locations and sizes of those branches as a result of the domain tasks remains an open question. With the aim of shedding light to the above question, we designed a sequence of experiments involving single-task networks, multi-task networks, and networks created with a neural architecture search (NAS) strategy. In addition, we proposed a competitive neural network architecture for a challenging use case: the ICAO photograph conformance checking for issuing of passports. We obtained the best results using a handcrafted MTL network, whose effectiveness is close to state-of-the-art methods. Furthermore, our experime nts and analysis pave the way to develop a technique to automatically create branches and group similar tasks into an MTL network. (More)
