On the Convergence of Continual Federated Learning Using Incrementally Aggregated Gradients

AISTATS 2025poster

The holy grail of machine learning is to enable Continual Federated Learning (CFL) to enhance the efficiency, privacy, and scalability of AI systems while learning from streaming data. The primary challenge of a CFL system is to overcome global catastrophic forgetting, wherein the accuracy of the gl…

Importance Sampling Based Federated Unsupervised Representation Learning

ICASSP 2024accepted

The use of AI has led to the era of pervasive intelligence, marked by a proliferation of smart devices in our daily lives. Federated Learning (FL) enables machine learning at the edge without having to share user-specific private data with an untrusted third party. Conventional FL techniques are sup…

Deep Survival Analysis and Counterfactual Inference Using Balanced Representations

ICASSP 2023accepted

Clinical decision making and diagnosis in healthcare is enabled by learning causal relationships among entities. In order to answer the question, ’Will changing the treatment regimen lead to quicker recovery of a patient?’ requires predicting counterfactuals using survival analysis. We seek to relia…

Variational Student: Learning Compact and Sparser Networks In Knowledge Distillation Framework

ICASSP 2020accepted

The holy grail in deep neural network research is porting the memory- and computation-intensive network models on embedded platforms with a minimal compromise in model accuracy. To this end, we propose Variational Student where we reap the benefits of compressibility of the knowledge distillation fr…

Sparse signal recovery in the presence of colored noise and rank-deficient noise covariance matrix: An SBL approach

ICASSP 2015accepted

In this work, we address the recovery of sparse and compressible vectors in the presence of colored noise possibly with a rank-deficient noise covariance matrix, from overcomplete noisy linear measurements. We exploit the structure of the noise covariance matrix in a Bayesian framework. In particula…
