What is unawareness (to a sensitive attribute)

Machine learning algorithms are becoming increasingly popular in various applications ranging from speech recognition to image classification. These algorithms are designed to identify patterns and make predictions that improve over time. However, one significant problem with machine learning is the potential to reveal sensitive information.

Sensitive attributes refer to any data point that can potentially discriminate against an individual or group’s identity, such as race, gender, religion, sexual orientation, etc. In machine learning algorithms, there is always the potential for these sensitive attributes to be inadvertently leaked, and this is known as unawareness.

Unawareness in machine learning can occur in two ways: direct and indirect. Direct unawareness happens when the algorithm explicitly uses sensitive information to make decisions. For example, an algorithm designed to provide personalized mortgage rates may use information such as the applicant’s race or gender to determine their eligibility for a specific rate. This type of discrimination is unethical and illegal, but it’s become a well-known problem in machine learning.

Indirect unawareness occurs when the algorithm uses seemingly unrelated data points to discriminate against sensitive information. For example, a credit scoring algorithm may use factors such as income, age or education level to provide a lower credit score to minority groups. The algorithm itself doesn’t include any reference to race or ethnicity explicitly, but it’s indirectly associated with it.

Machine learning algorithms are only as unbiased as the data they are trained on, and if the data set is not properly cleaned, aware or unintentional bias can creep into the system. If there are not enough minorities in the training data set, for example, the algorithm may not learn how to make decisions that account for these groups’ unique needs. This is commonly known as the cold start problem in machine learning and can lead to the algorithm being unaware of certain attributes.

The unawareness problem can occur in any type of machine learning algorithm, but there are ways to prevent it. One potential solution is to ensure the training data set is diverse and representative of all groups. Another approach is to create more transparent algorithms that explicitly prevent the use of sensitive information in the decision-making process. Disclosing how the algorithm works can also help eliminate implicit bias, as it provides a way to test the algorithm for bias and increase awareness of potential issues.

In conclusion, unawareness of sensitive attributes in machine learning is an ongoing concern that society must address. As more companies, government organizations, and individuals use machine learning to make decisions, it’s essential to understand the potential ethical implications of the technology. By building transparent, unbiased algorithms and ensuring that data sets are diverse, we can begin to address the problem of unawareness and create a more equitable society.
