Neural networks are a popular and powerful tool in machine learning. However, they can be notoriously difficult to interpret, leading to concerns about their use in high-stakes decision-making contexts, such as healthcare or criminal justice.

Explainability in Neural Networks

Explainability in neural networks refers to the ability to understand and justify the decisions made by the network.

Layer-wise Relevance Propagation

One approach to achieving explainability in neural networks is layer-wise relevance propagation (LRP). LRP assigns relevance scores to each input feature, indicating how important it was in the network's decision. This can help identify which features are driving the network's decision and provide insight into the underlying logic of the network.

Attention Mechanisms

Another approach to achieving explainability in neural networks is through the use of attention mechanisms. Attention mechanisms give a weight to each input feature, indicating how important it is for the network's decision. This is useful for understanding which features the network is focusing on and can provide insight into the decision-making process.

Overall, explainability in neural networks is an important area of research, with many potential applications in areas such as healthcare, criminal justice, and finance. It is important to continue to develop new methods for achieving explainability in neural networks to address concerns about their use in high-stakes decision-making contexts.
