Heterogeneous graphs model spatial relationships between biological entities for breast cancer diagnosis

no code implementations16 Jul 2023 Akhila Krishna K, Ravi Kant Gupta, Nikhil Cherian Kurian, Pranav Jeevan, Amit Sethi

The heterogeneity of breast cancer presents considerable challenges for its early detection, prognosis, and treatment selection.

Robust Semi-Supervised Learning for Histopathology Images through Self-Supervision Guided Out-of-Distribution Scoring

no code implementations17 Mar 2023 Nikhil Cherian Kurian, Varsha S, Abhijit PATIL, Shashikant Khade, Amit Sethi

The outlier score derived from the OOD detector is used to modulate sample selection for the subsequent semi-SL stage, ensuring that samples conforming to the distribution of the few labeled samples are more frequently exposed to the subsequent semi-SL framework.
