What are the most important problems in face recognition?

Answer:

The biggest challenge in face recognition task is to perform it with a certain level of reliability and vulnerability.

1. Reliability

As far as face recognition is mainly focused on identifying a person, every solution based on this technology must have explicit requirements to the quality of algorithms behind it so the mistake is that big as it is acceptable considering the purpose of the solution.

It can't have 70% in accuracy metric if it is responsible for granting access to personal information, and at the same time it could be fine if its task is to count average number of visitors in the store.

2. Vulnerability

We need to know what are weak spots in our algorithms: whether it is performance or instability of deep neural network models to strategic noise.

It is crucial to have close collaboration between business and technical specialists to find out all insecure&vulnerable cases, anticipate level of troubles that might happen due to them and eliminate or decrease impact of any of those issues
