Demystifying Deep Learning Decisions in Leukemia Diagnostics Using Explainable AI
This study proposes an AI pipeline integrating CNNs and transfer learning with XAI (LIME and Grad-Cam) for leukemia diagnostics. It aims for high accuracy and transparent rationales, addressing the variability and cost of conventional methods. A large unified benchmark (66,550 images) covering various leukemia types (ALL, AML, CLL, CML) and healthy controls was curated. The models were fine-tuned and evaluated on accuracy and F1-score, benchmarking against literature.

Case Study: Enhancing ALL Subtype Classification
In a critical scenario involving the differentiation of ALL subtypes (Benign, Early, Pre, Pro), our AI pipeline demonstrated exceptional performance and clarity.
Challenge: Accurate and timely subtyping of ALL is crucial for personalized treatment but is challenging due to subtle morphological variations and inter-observer variability among pathologists.
Solution: DenseNet121 and MobileNetV2 models, fine-tuned with MixUp augmentation, were employed to classify ALL subtypes. XAI methods (LIME and Grad-CAM) were integrated to provide visual explanations of the model's decisions.
Outcome: The models achieved state-of-the-art accuracy with DenseNet121 showing near-ceiling performance on the ALL-subtype dataset. XAI visualizations consistently highlighted key nuclear and cytoplasmic features relevant to each subtype, providing strong interpretability and corroborating clinical findings, thus building trust for adoption in diagnostic workflows.
