Learning to Receive Help: Intervention-Aware Concept Embedding Models

1 code implementation NeurIPS 2023 Mateo Espinosa Zarlenga, Katherine M. Collins, Krishnamurthy Dvijotham, Adrian Weller, Zohreh Shams, Mateja Jamnik

To address this, we propose Intervention-aware Concept Embedding models (IntCEMs), a novel CBM-based architecture and training paradigm that improves a model's receptiveness to test-time interventions.

Gene Expression Patterns of CsZCD and Apocarotenoid Accumulation during Saffron Stigma Development

no code implementations15 Sep 2023 Zohreh Shams

A noteworthy observation was that CsZCD's expression was three times that of the CsTUB gene.

CGXplain: Rule-Based Deep Neural Network Explanations Using Dual Linear Programs

1 code implementation11 Apr 2023 Konstantin Hemker, Zohreh Shams, Mateja Jamnik

Rule-based surrogate models are an effective and interpretable way to approximate a Deep Neural Network's (DNN) decision boundaries, allowing humans to easily understand deep learning models.

Towards Robust Metrics for Concept Representation Evaluation

1 code implementation25 Jan 2023 Mateo Espinosa Zarlenga, Pietro Barbiero, Zohreh Shams, Dmitry Kazhdan, Umang Bhatt, Adrian Weller, Mateja Jamnik

In this paper, we show that such metrics are not appropriate for concept learning and propose novel metrics for evaluating the purity of concept representations in both approaches.

Efficient Decompositional Rule Extraction for Deep Neural Networks

1 code implementation24 Nov 2021 Mateo Espinosa Zarlenga, Zohreh Shams, Mateja Jamnik

In recent years, there has been significant work on increasing both interpretability and debuggability of a Deep Neural Network (DNN) by extracting a rule-based model that approximates its decision boundary.

On The Quality Assurance Of Concept-Based Representations

no code implementations29 Sep 2021 Mateo Espinosa Zarlenga, Pietro Barbiero, Zohreh Shams, Dmitry Kazhdan, Umang Bhatt, Mateja Jamnik

Recent work on Explainable AI has focused on concept-based explanations, where deep learning models are explained in terms of high-level units of information, referred to as concepts.

Incorporating network based protein complex discovery into automated model construction

no code implementations29 Sep 2020 Paul Scherer, Maja Trȩbacz, Nikola Simidjievski, Zohreh Shams, Helena Andres Terre, Pietro Liò, Mateja Jamnik

We propose a method for gene expression based analysis of cancer phenotypes incorporating network biology knowledge through unsupervised construction of computational graphs.

Practical Reasoning with Norms for Autonomous Software Agents (Full Edition)

no code implementations28 Jan 2017 Zohreh Shams, Marina De Vos, Julian Padget, Wamberto W. Vasconcelos

Autonomous software agents operating in dynamic environments need to constantly reason about actions in pursuit of their goals, while taking into consideration norms which might be imposed on those actions.
