The existing Shapley value based frameworks for data valuation in machine learning are computationally expensive as they require considerable amount of repeated training of the model to obtain the Shapley value. In this paper, we introduce an efficient data valuation framework EcoVal, to estimate the value of data for machine learning models in a fast and practical manner. Instead of directly working with individual data sample, we determine the value of a cluster of similar data points. This value is further propagated amongst all the member cluster points. We show that the overall data value can be determined by estimating the intrinsic and extrinsic value of each data. This is enabled by formulating the performance of a model as a production function, a concept which is popularly used to estimate the amount of output based on factors like labor and capital in a traditional free economic market. We provide a formal proof of our valuation technique and elucidate the principles and mechanisms that enable its accelerated performance. We demonstrate the real-world applicability of our method by showcasing its effectiveness for both in-distribution and out-of-sample data. This work addresses one of the core challenges of efficient data valuation at scale in machine learning models.  \n1 Introduction  \nData valuation is a pivotal concern in modern machine learning (ML) and data analytics, where the quality and worth of data have profound implications for decision-making, model performance, and data marketplace. Quantifying the worth of data plays an important role in data pricing and regulation compliance [1, 2], removing low-value/noisy data from the training set [3, 4], and incentivizing data sharing by personal data monetization [5, 6, 7, 8] . In a ML framework, the quality of data determines the effectiveness of the final model. Therefore, identifying high and low value data through data valuation would yield s","cbCair2RLxZo2lD6","https://ap.wps.com/l/cbCair2RLxZo2lD6","pdf",3807187,1,15,"English","en",105,"# Abstract\n# Introduction\n## Data valuation in machine learning\n## Background: Shapley value for data valuation\n## Motivation: computational cost of existing methods","[{\"question\":\"Why are Shapley value-based data valuation methods expensive in practice?\",\"answer\":\"They require repeated training runs to estimate contributions, typically leading to quadratic-scale computational cost in the number of data points.\"},{\"question\":\"What core idea does EcoVal use to estimate data value efficiently?\",\"answer\":\"EcoVal estimates value at the level of clusters of similar data points instead of individual samples, then propagates cluster value to all points within the cluster.\"},{\"question\":\"How does EcoVal determine overall data value?\",\"answer\":\"It decomposes value into intrinsic and extrinsic components by formulating model performance as a production function, supported by formal proof and practical validation.\"}]","EcoVal -
