A fifth challenge of deep learning is that it involves human factors, which means that it can be influenced by the human behavior, cognition, and emotions of the developers, users, and attackers of the models. For example, human factors can introduce biases, errors, or conflicts into the models and their outputs, and affect their quality and reliability. Moreover, human factors can create ethical, social, or psychological issues that can affect the trust, acceptance, and satisfaction of the users and the stakeholders of the models. For example, some users may feel uncomfortable, insecure, or threatened by the models and their capabilities, and some stakeholders may have different or conflicting expectations, interests, or values regarding the models and their outcomes. To address this challenge, cybersecurity professionals need to consider the human factors that can impact the models and their applications, and to involve the users and the stakeholders in the design, development, and evaluation of the models, and to ensure that they respect the human dignity, rights, and preferences of the users and the stakeholders.
