UniRecSys: A Unified Framework for Personalized, Group, Package, and Package-to-Group Recommendations

no code implementations8 Aug 2023 Adamya Shyam, Vikas Kumar, Venkateswara Rao Kagita, Arun K Pujari

We consider two prominent CF techniques, namely Regularized Matrix Factorization and Maximum Margin Matrix factorization, as the baseline models and demonstrate their customization to various recommendation tasks.

Conformal Group Recommender System

no code implementations22 Jul 2023 Venkateswara Rao Kagita, Anshuman Singh, Vikas Kumar, Pavan Kalyan Reddy Neerudu, Arun K Pujari, Rohit Kumar Bondugula

The traditional models of group recommendation are designed to act like a black box with a strict focus on improving recommendation accuracy, and most often, they place the onus on the users to interpret recommendations.

Data augmentation and refinement for recommender system: A semi-supervised approach using maximum margin matrix factorization

no code implementations22 Jun 2023 Shamal Shaikh, Venkateswara Rao Kagita, Vikas Kumar, Arun K Pujari

We exploit the inherent characteristics of CF algorithms to assess the confidence level of individual ratings and propose a semi-supervised approach for rating augmentation based on self-training.

Transfer of codebook latent factors for cross-domain recommendation with non-overlapping data

no code implementations26 Mar 2022 Sowmini Devi Veeramachaneni, Arun K Pujari, Vineet Padmanabhan, Vikas Kumar

In this paper, we come up with a novel transfer learning approach for cross-domain recommendation, wherein the cluster-level rating pattern(codebook) of the source domain is obtained via a co-clustering technique.

Inductive Conformal Recommender System

no code implementations18 Sep 2021 Venkateswara Rao Kagita, Arun K Pujari, Vineet Padmanabhan, Vikas Kumar

The conformal recommender system uses the experience of a user to output a set of recommendations, each associated with a precise confidence value.

Committee Selection with Attribute Level Preferences

no code implementations29 Jan 2019 Venkateswara Rao Kagita, Arun K Pujari, Vineet Padmanabhan, Vikas Kumar

We describe a greedy approach for attribute aggregation that satisfies the first three properties, but not the fourth, i. e., compound justified representation, which we prove to be NP-complete.
