Classifier Data Quality: A Geometric Complexity Based Method for Automated Baseline And Insights Generation

no code implementations22 Dec 2021 George Kour, Marcel Zalmanovici, Orna Raz, Samuel Ackerman, Ateret Anaby-Tavor

Testing Machine Learning (ML) models and AI-Infused Applications (AIIAs), or systems that contain ML models, is highly challenging.

Automatically detecting data drift in machine learning classifiers

no code implementations10 Nov 2021 Samuel Ackerman, Orna Raz, Marcel Zalmanovici, Aviad Zlotnick

The assumption underlying statistical ML resulting in theoretical or empirical performance guarantees is that the distribution of the training data is representative of the production data distribution.

Density-based interpretable hypercube region partitioning for mixed numeric and categorical data

no code implementations11 Oct 2021 Samuel Ackerman, Eitan Farchi, Orna Raz, Marcel Zalmanovici, Maya Zohar

A user may want to know where in the feature space observations are concentrated, and where it is sparse or empty.

FreaAI: Automated extraction of data slices to test machine learning models

no code implementations12 Aug 2021 Samuel Ackerman, Orna Raz, Marcel Zalmanovici

In this paper we show the feasibility of automatically extracting feature models that result in explainable data slices over which the ML solution under-performs.

BIG-bench Machine Learning

Detection of data drift and outliers affecting machine learning model performance over time

no code implementations16 Dec 2020 Samuel Ackerman, Eitan Farchi, Orna Raz, Marcel Zalmanovici, Parijat Dube

Drift is distribution change between the training and deployment data, which is concerning if model performance changes.
