Predicting Question-Answering Performance of Large Language Models through Semantic Consistency

no code implementations2 Nov 2023 Ella Rabinovich, Samuel Ackerman, Orna Raz, Eitan Farchi, Ateret Anaby-Tavor

Semantic consistency of a language model is broadly defined as the model's ability to produce semantically-equivalent outputs, given semantically-equivalent inputs.

Characterizing how 'distributional' NLP corpora distance metrics are

1 code implementation23 Oct 2023 Samuel Ackerman, George Kour, Eitan Farchi

We quantify this quality by constructing a Known-Similarity Corpora set from two paraphrase corpora and calculating the distance between paired corpora from it.

Data Drift Monitoring for Log Anomaly Detection Pipelines

no code implementations17 Oct 2023 Dipak Wani, Samuel Ackerman, Eitan Farchi, Xiaotong Liu, Hau-wen Chang, Sarasi Lalithsena

Logs enable the monitoring of infrastructure status and the performance of associated applications.

Reliable and Interpretable Drift Detection in Streams of Short Texts

no code implementations28 May 2023 Ella Rabinovich, Matan Vetzler, Samuel Ackerman, Ateret Anaby-Tavor

Data drift is the change in model input data that is one of the key factors leading to machine learning models performance degradation over time.

Automatic Generation of Attention Rules For Containment of Machine Learning Model Errors

no code implementations14 May 2023 Samuel Ackerman, Axel Bendavid, Eitan Farchi, Orna Raz

The approach we propose is to separate the observations that are the most likely to be predicted incorrectly into 'attention sets'.

Measuring the Measuring Tools: An Automatic Evaluation of Semantic Metrics for Text Corpora

2 code implementations29 Nov 2022 George Kour, Samuel Ackerman, Orna Raz, Eitan Farchi, Boaz Carmeli, Ateret Anaby-Tavor

The ability to compare the semantic similarity between text corpora is important in a variety of natural language processing applications.

Theory and Practice of Quality Assurance for Machine Learning Systems An Experiment Driven Approach

no code implementations2 Jan 2022 Samuel Ackerman, Guy Barash, Eitan Farchi, Orna Raz, Onn Shehory

The crafting of machine learning (ML) based systems requires statistical control throughout its life cycle.

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.

Using sequential drift detection to test the API economy

no code implementations9 Nov 2021 Samuel Ackerman, Parijat Dube, Eitan Farchi

It is thus desirable to monitor the usage patterns and identify when the system is used in a way that was never used before.

Detecting model drift using polynomial relations

no code implementations24 Oct 2021 Eliran Roffe, Samuel Ackerman, Orna Raz, Eitan Farchi

We thus use a set of learned strong polynomial relations to identify drift.

Towards API Testing Across Cloud and Edge

no code implementations6 Sep 2021 Samuel Ackerman, Sanjib Choudhury, Nirmit Desai, Eitan Farchi, Dan Gisolfi, Andrew Hicks, Saritha Route, Diptikalyan Saha

API economy is driving the digital transformation of business applications across the hybrid Cloud and edge environments.

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.

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.

Sequential Drift Detection in Deep Learning Classifiers

no code implementations31 Jul 2020 Samuel Ackerman, Parijat Dube, Eitan Farchi

We utilize neural network embeddings to detect data drift by formulating the drift detection within an appropriate sequential decision framework.
