Abstract: Broadly speaking, the present techniques generally relate to a method for training a machine learning, ML, model to perform semantic image segmentation, and to a computer-implemented method and apparatus for performing semantic image segmentation using a trained machine learning, ML, model. The training method enables a semantic image segmentation ML model that is able to make predictions faster, without significant loss in accuracy. The training method also enables the ML model to be implemented on apparatus with different hardware specifications, i.e. different computational power and memory, for example.

Abstract: Broadly speaking, the present techniques generally relates to methods, systems and apparatuses for training a machine learning (ML) model using federated learning. In particular, a method for training a machine learning (ML) model using federated learning performed by a plurality of client devices, the method comprising determining a computation capability of each client device, associating each client device with a value defining how much of each neural network layer of the ML model is to be included in a submodel to be trained by the each client device, based on the determined computation capability and generating a submodel of the ML model by using the value associated with the each client device to perform ordered pruning of at least one neural network layer of the ML model, is provided.

Abstract: Broadly speaking, the present techniques relate to methods and systems for dynamically distributing the execution of a neural network across multiple computing resources in order to satisfy various criteria associated with implementing the neural network. For example, the distribution may be performed to spread the processing load across multiple device, which may enable the neural network computation to be performed quicker than if performed by a single device and more cost-effectively than if the computation was performed entirely by a cloud server.

Abstract: Disclosed is an electronic apparatus. The electronic apparatus includes a memory storing at least one instruction, and a processor coupled to the memory and configured to control the electronic apparatus, the processor configured to identify one of a plurality of exit points included in a neural network based on at least one constraint in at least one of processing or the electronic apparatus, process the input data via the neural network and obtain processing results output from the identified exit point as output data.
