Fog computing promises to enable machine learning tasks scale large amounts of data by distributing processing across connected devices. Two key challenges achieving this are (i) heterogeneity in devices' compute resources and (ii) topology constraints on which devices can communicate. We the first address these developing a network-aware distributed optimization methodology where process for task locally send their learnt parameters server aggregation at certain time intervals.

The emergence of the paradigm Internet Things (IoT) has necessitated development machine-to-machine (M2M) protocols geared towards wireless sensor network interfacing to and implementing machine learning algorithms over cloud. This paper discusses viability MQ Telemetry Transport (MQTT) protocol for such applications. introduces MQTT along with its merits demerits suitability IoT Then it outlines an implementation a typical application involving ubiquitous sensing, M2M communication, cloud...
Federated learning (FL) is a popular solution for distributed machine (ML). While FL has traditionally been studied supervised ML tasks, in many applications, it impractical to assume availability of labeled data across devices. To this end, we develop Cooperative unsupervised Contrastive Learning (CF-CL) facilitate edge devices with unlabeled datasets. CF-CL employs local device cooperation where either explicit (i.e., raw data) or implicit embeddings) information exchanged through...
Augmenting federated learning (FL) with direct device-to-device (D2D) communications can help improve conver-gence speed and reduce model bias through rapid local information exchange. However, data privacy concerns, device trust issues, unreliable wireless channels each pose challenges to determining an effective yet resource efficient D2D structure. In this paper, we develop a decentralized reinforcement (RL) methodology for graph discovery that promotes communication of non-sensitive...

One of the main challenges decentralized machine learning paradigms such as Federated Learning (FL) is presence local non-i.i.d. datasets. Device-to-device transfers (D2D) between distributed devices has been shown to be an effective tool for dealing with this problem and robust stragglers. In unsupervised case, however, it not obvious how data exchanges should take place due absence labels. paper, we propose approach create optimal graph transfer using Reinforcement Learning. The goal form...
