$β$-calibration of Language Model Confidence Scores for Generative QA

no code implementations9 Oct 2024 Putra Manggala, Atalanti Mastakouri, Elke Kirschbaum, Shiva Prasad Kasiviswanathan, Aaditya Ramdas

To use generative question-and-answering (QA) systems for decision-making and in any critical application, these systems need to provide well-calibrated confidence scores that reflect the correctness of their answers.

Estimating Joint interventional distributions from marginal interventional data

no code implementations3 Sep 2024 Sergio Hernan Garrido Mejia, Elke Kirschbaum, Armin Kekić, Atalanti Mastakouri

In this paper we show how to exploit interventional data to acquire the joint conditional distribution of all the variables using the Maximum Entropy principle.

Score matching through the roof: linear, nonlinear, and latent variables causal discovery

no code implementations26 Jul 2024 Francesco Montagna, Philipp M. Faller, Patrick Bloebaum, Elke Kirschbaum, Francesco Locatello

Causal discovery from observational data holds great promise, but existing methods rely on strong assumptions about the underlying causal structure, often requiring full observability of all relevant variables.

The PetShop Dataset -- Finding Causes of Performance Issues across Microservices

1 code implementation8 Nov 2023 Michaela Hardt, William R. Orchard, Patrick Blöbaum, Shiva Kasiviswanathan, Elke Kirschbaum

Although the machine learning and systems research communities have proposed various techniques to tackle this problem, there is currently a lack of standardized datasets for quantitative benchmarking.

Obtaining Causal Information by Merging Datasets with MAXENT

no code implementations15 Jul 2021 Sergio Hernan Garrido Mejia, Elke Kirschbaum, Dominik Janzing

Another similarly important and challenging task is to quantify the causal influence of a treatment on a target in the presence of confounders.

DISCo: Deep learning, Instance Segmentation, and Correlations for cell segmentation in calcium imaging

1 code implementation21 Aug 2019 Elke Kirschbaum, Alberto Bailoni, Fred A. Hamprecht

In order to use the data gained with calcium imaging, it is necessary to extract individual cells and their activity from the recordings.

LeMoNADe: Learned Motif and Neuronal Assembly Detection in calcium imaging videos

1 code implementation ICLR 2019 Elke Kirschbaum, Manuel Haußmann, Steffen Wolf, Hannah Jakobi, Justus Schneider, Shehabeldin Elzoheiry, Oliver Kann, Daniel Durstewitz, Fred A. Hamprecht

Neuronal assemblies, loosely defined as subsets of neurons with reoccurring spatio-temporally coordinated activation patterns, or "motifs", are thought to be building blocks of neural representations and information processing.

Sparse convolutional coding for neuronal assembly detection

1 code implementation NeurIPS 2017 Sven Peter, Elke Kirschbaum, Martin Both, Lee Campbell, Brandon Harvey, Conor Heins, Daniel Durstewitz, Ferran Diego, Fred A. Hamprecht

Cell assemblies, originally proposed by Donald Hebb (1949), are subsets of neurons firing in a temporally coordinated way that gives rise to repeated motifs supposed to underly neural representations and information processing.
