Sayeda  \na School of Engineering, EPFL, CH-1015, Lausanne, Switzerland  \nAbstract  \nThis paper studies the probability of error associated with the social machine learning framework, which involves an independent training phase followed by a cooperative decision-making phase over a graph. This framework addresses the problem of classifying a stream of unlabeled data in a distributed manner. In this work, we examine the classification task with limited observations during the decision-making phase, which requires a non-asymptotic performance analysis. We establish a condition for consistent training and derive an upper bound on the probability of error for classification. The results clarify the dependence on the statistical properties of the data and the combination policy used over the graph. They also establish the exponential decay of the probability of error with respect to the number of unlabeled samples.  \nKeywords: Social machine learning, probability of error, classification, non-asymptotic analysis  \n1. Introduction  \nSocial learning is a useful paradigm for addressing decision-making tasks involving a group of agents. Practical applications arise in various scenarios, such as detection and object recognition using autonomous robots, as well as statistical inference and learning across multiple processors [2] . In this paper, we focus on the social machine learning (SML) framework introduced in [3], which is a data-driven cooperative decisionmaking paradigm. The main motivation for the introduction of this framework is to address a critical limitation of traditional social learning solutions [4–11] . These solutions allow a group of agents to interact over a graph to arrive at consensus decisions about a hypothesis of interest. However, a limiting assumption in all these studies is the requirement that the likelihood models for data generation are known beforehand. The SML strategy removes this requirement, thus opening up the door for solving classification tasks in a distributed manner with performance guarantees by relying solely on a data-driven implementation.  \n⋆ A preliminary short conference version of this work was previously published in [1] .  \n∗ Corresponding author  \nEmail addresses: [ping.hu@epfl.ch](ping.hu@epfl.ch) (Ping Hu), [virginia.bordignon@epfl.ch](virginia.bordignon@epfl.ch) (Virginia Bordignon),  \n[mert.kayaalp@epfl.ch](mert.kayaalp@epfl.ch) (Mert Kayaalp), [ali.sayed@epfl.ch](ali.sayed@epfl.ch) (Ali H.

The neighboring set Nk of agent k is marked by the area highlighted in gray.  \nThe SML strategy involves two learning phases, as depicted in Fig. 1. In the training phase on the left, each agent trains a classifier independently using a finite set of labeled samples within a supervised learning framework (such as logistic regression, neural networks, or other convenient frameworks) . The purpose of this phase is to learn some discriminative information that allows agents to distinguish different hypotheses. The output of each trained classifier is used to form a local decision statistic for inference in ","cbCailPLfvd6i3do","https://ap.wps.com/l/cbCailPLfvd6i3do","pdf",2274067,1,36,"English","en",105,"# Introduction\n## SML framework and motivation\n## Two-phase learning: training and prediction\n## Performance guarantees and problem setting","[{\"question\":\"What are the two learning phases in the social machine learning (SML) framework?\",\"answer\":\"SML uses an independent training phase followed by a cooperative prediction phase over a graph.
