Choice Models and Permutation Invariance: Demand Estimation in Differentiated Products Markets

no code implementations13 Jul 2023 Amandeep Singh, Ye Liu, Hema Yoganarasimhan

We demonstrate how non-parametric estimators like neural nets can easily approximate such functionals and overcome the curse of dimensionality that is inherent in the non-parametric estimation of choice functions.

Interpretable Anomaly Detection in Cellular Networks by Learning Concepts in Variational Autoencoders

no code implementations28 Jun 2023 Amandeep Singh, Michael Weber, Markus Lange-Hegermann

This paper addresses the challenges of detecting anomalies in cellular networks in an interpretable way and proposes a new approach using variational autoencoders (VAEs) that learn interpretable representations of the latent space for each Key Performance Indicator (KPI) in the dataset.

Can LLMs Capture Human Preferences?

no code implementations4 May 2023 Ali Goli, Amandeep Singh

We explore the viability of Large Language Models (LLMs), specifically OpenAI's GPT-3. 5 and GPT-4, in emulating human survey respondents and eliciting preferences, with a focus on intertemporal choices.

no code implementations16 Nov 2022 Jingwen Zhang, Yifang Chen, Amandeep Singh

To this end, in this paper, we consider the problem of online learning in linear stochastic contextual bandit problems with endogenous covariates.

User-friendly Comparison of Similarity Algorithms on Wikidata

1 code implementation11 Aug 2021 Filip Ilievski, Pedro Szekely, Gleb Satyukov, Amandeep Singh

While the similarity between two concept words has been evaluated and studied for decades, much less attention has been devoted to algorithms that can compute the similarity of nodes in very large knowledge graphs, like Wikidata.

Sparse-Push: Communication- & Energy-Efficient Decentralized Distributed Learning over Directed & Time-Varying Graphs with non-IID Datasets

no code implementations10 Feb 2021 Sai Aparna Aketi, Amandeep Singh, Jan Rabaey

Current deep learning (DL) systems rely on a centralized computing paradigm which limits the amount of available training data, increases system latency, and adds privacy and security constraints.

Causal Gradient Boosting: Boosted Instrumental Variable Regression

no code implementations15 Jan 2021 Edvard Bakhitov, Amandeep Singh

In this paper, we propose an alternative algorithm called boostIV that builds on the traditional gradient boosting algorithm and corrects for the endogeneity bias.
