(1) Latency-Memory Optimized Splitting of Convolution Neural Networks for Resource Constrained Edge Devices


With the increasing reliance of users on smart devices, bringing essential computation at the edge has become
a crucial requirement for any type of business. Many such computations utilize Convolution Neural Networks (CNNs) to
perform AI tasks, having high resource and computation requirements, that are infeasible for edge devices. Splitting the
CNN architecture to perform part of the computation on edge and remaining on the cloud is an area of research that has
seen increasing interest in the field. In this work, we assert that running CNNs between an edge device and the cloud is synonymous with solving a resource-constrained optimization problem that minimizes the latency and maximizes resource utilization at
the edge. We formulate a multi-objective optimization problem and propose the LMOS algorithm to achieve a Pareto efficient
solution. Experiments done on real-world edge devices show that LMOS ensures feasible execution of different CNN models at the
edge and also improves upon existing state-of-the-art approaches.

(2) Federated Learning in a Faulty Edge Ecosystem: Analysis, Mitigation and Applications


Federated Learning deviates from the norm of ”send data to model” to ”send model to data”. When used in an
edge ecosystem, numerous heterogeneous edge devices collecting data through different means and connected through different
network channels get involved in the training process. Failure of edge devices in such an ecosystem due to device fault or
network issues is highly likely. In this work, we first analyse the impact of the number of edge devices on an FL model and
provide a strategy to select an optimal number of devices that would contribute to the model. We observe the impact of
data distribution on the number of optimal devices. We then investigate how the edge ecosystem behaves when the selected
devices fail and provide a mitigation strategy to ensure a robust Federated Learning technique. Finally, we design a real-world
application to highlight the impact of the designed mitigation strategy.
