Ep 16 | Explainable AI - A Specific Use Case and General Principles w. Akash Parvatikar (HistoWiz)
Description
Back in 2021, Akash Parvatikar Co-authored a paper titled - 'Prototypical models for classifying high-risk atypical breast lesions'. The premise was that some breast lesions are particularly challenging to classify, leading to different pathologists making different diagnoses based on the same information. The paper aimed to reduce this variability by providing a consistent computational method.
A key contribution of this work is that the AI model can explain its recommendations in a way that is useful for clinical practice. This is important because doctors need to understand why an AI system has made a particular diagnosis to trust and act on its recommendations.
In this episode, Akash discusses his work in relation to xAI in diagnosing breast cancer. He discusses the model he developed, which outperformed baseline models in detecting high-risk breast lesions. Akash emphasizes the importance of xAI in building trust and transparency in clinical decision-making tools and explains how his model incorporates explainability through feature detection and contribution scores.
Akash emphasizes the need for explanations to be provided frequently to end users, as it plays a crucial role in building trust in AI systems. He also highlights the importance of involving domain experts in the development of AI models.
