B. Engagement
C. Demographic

Answer

C. Demographic

Explanation

Demographic data should be omitted to avoid introducing unintended bias to an AI model. Demographic data is data that describes the characteristics of a population or a group of people, such as age, gender, race, ethnicity, income, education, or occupation. Demographic data can lead to bias if it is used to discriminate or treat people differently based on their identity or attributes. Demographic data can also reflect existing biases or stereotypes in society or culture, which can affect the fairness and ethics of AI systems.

Demographic data refers to information that describes the characteristics of a population or a subset of it, such as age, gender, race, ethnicity, income, education, occupation, and so on. Demographic data can be useful for understanding the needs, preferences, and behaviors of different groups of people, and for designing products and services that cater to them. However, demographic data can also introduce unintended bias to an AI model if it is used inappropriately or without proper safeguards.

Bias in AI is a deviation from the expected or desired outcome that harms or disadvantages some individuals or groups. Bias can arise from various sources, such as the data, the algorithms, the context, or the human factors involved in the AI system. One of the most common sources of bias is the data used to train or validate the AI model, which can reflect the existing prejudices, stereotypes, or inequalities in the real world.

If demographic data is used as an input or a feature for an AI model, it can potentially influence the model’s predictions or decisions in ways that are unfair or discriminatory for certain groups or individuals. For example, an AI model that uses demographic data to determine the eligibility of applicants for a loan, a job, or a school admission could end up favoring or disfavoring some groups based on their demographic attributes, rather than their actual qualifications or merits. This could result in negative impacts for the affected groups, such as lower opportunities, lower incomes, lower quality of life, or lower social status.

Therefore, to avoid introducing unintended bias to an AI model, demographic data should be omitted or handled with caution. Some possible strategies to mitigate the bias from demographic data include:

• Removing or masking the demographic variables or their proxies from the data, unless they are relevant or necessary for the specific task or domain
• Balancing or augmenting the data to ensure that it represents the diversity and distribution of the target population or the intended users
• Applying techniques such as regularization, adversarial learning, or fair representation learning to reduce the dependence or influence of the demographic variables on the model’s outputs
• Evaluating and testing the model’s performance and fairness across different demographic groups, using appropriate metrics and criteria
• Explaining and documenting the model’s rationale and assumptions, and disclosing the potential sources and impacts of bias to the stakeholders and users
