DATA BIAS

Understanding Data Bias

Many data sources used for training machine learning (ML) models are user-generated, often leading to bias and imbalance. Data imbalance means that certain groups, features, or categories are underrepresented in the dataset. As a result, the ML model may exhibit:

1. Bias in Decision-Making: Models tend to favour overrepresented classes or groups, leading to unfair outcomes, particularly for minority groups.
2. Poor Generalisation: The model struggles to generalize beyond the dominant patterns in the training data, reducing its effectiveness in real-world applications.
3. Amplification of Social Inequalities: Biases present in training data can be perpetuated or magnified, adversely impacting decision-making in critical areas like hiring, lending, or healthcare.

It is crucial to understand bias sources so that it can be mitigated effectively. Here are some data biases:

• Historical Bias
• Sampling Bias
• Representation Bias
• Cognitive Bias

Tackling data bias requires a systematic, proactive approach. You can get started with these resources:
