CLIMAX: An exploration of Classifier-Based Contrastive Explanations

1 code implementation2 Jul 2023 Praharsh Nanavati, Ranjitha Prasad

Our method, which we refer to as CLIMAX which is short for Contrastive Label-aware Influence-based Model Agnostic XAI, is based on local classifiers .

Over-The-Air Clustered Wireless Federated Learning

no code implementations7 Nov 2022 Ayush Madhan-Sohini, Divin Dominic, Nazreen Shah, Ranjitha Prasad

Privacy and bandwidth constraints have led to the use of federated learning (FL) in wireless systems, where training a machine learning (ML) model is accomplished collaboratively without sharing raw data.

DAGSurv: Directed Acyclic Graph Based Survival Analysis Using Deep Neural Networks

1 code implementation2 Nov 2021 Ansh Kumar Sharma, Rahul Kukreja, Ranjitha Prasad, Shilpa Rao

Causal structures for observational survival data provide crucial information regarding the relationships between covariates and time-to-event.

Select Wisely and Explain: Active Learning and Probabilistic Local Post-hoc Explainability

1 code implementation16 Aug 2021 Aditya Saini, Ranjitha Prasad

Albeit the tremendous performance improvements in designing complex artificial intelligence (AI) systems in data-intensive domains, the black-box nature of these systems leads to the lack of trustworthiness.

B-SMALL: A Bayesian Neural Network approach to Sparse Model-Agnostic Meta-Learning

1 code implementation1 Jan 2021 Anish Madan, Ranjitha Prasad

We demonstrate the performance of B-MAML using classification and regression tasks, and highlight that training a sparsifying BNN using MAML indeed improves the parameter footprint of the model while performing at par or even outperforming the MAML approach.

CAMTA: Causal Attention Model for Multi-touch Attribution

no code implementations21 Dec 2020 Sachin Kumar, Garima Gupta, Ranjitha Prasad, Arnab Chatterjee, Lovekesh Vig, Gautam Shroff

Advertising channels have evolved from conventional print media, billboards and radio advertising to online digital advertising (ad), where the users are exposed to a sequence of ad campaigns via social networks, display ads, search etc.

MetaCI: Meta-Learning for Causal Inference in a Heterogeneous Population

no code implementations9 Dec 2019 Ankit Sharma, Garima Gupta, Ranjitha Prasad, Arnab Chatterjee, Lovekesh Vig, Gautam Shroff

Performing inference on data obtained through observational studies is becoming extremely relevant due to the widespread availability of data in fields such as healthcare, education, retail, etc.

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

no code implementations26 Oct 2019 Srinidhi Hegde, Ranjitha Prasad, Ramya Hebbalaguppe, Vishwajith Kumar

We demonstrate that the marriage of KD and the VI techniques inherits compression properties from the KD framework, and enhances levels of sparsity from the VI approach, with minimal compromise in the model accuracy.

Lower Bounds on the Bayes Risk of the Bayesian BTL Model with Applications to Comparison Graphs

no code implementations27 Sep 2017 Mine Alsan, Ranjitha Prasad, Vincent Y. F. Tan

In particular, we employ the Bayesian BTL model which allows for meaningful prior assumptions and to cope with situations where the number of objects is large and the number of comparisons between some objects is small or even zero.
