An Optimiser is an algorithm that adjusts model parameters during training to minimise a loss function, guiding convergence towards an optimal solution. Modern optimisers such as Adam, RMSProp, and AdaGrad extend stochastic gradient descent with adaptive learning rates, momentum accumulation, and second-moment estimates, enabling faster and more stable training of deep neural networks across diverse tasks.

Academic Context
- Brief contextual overview
- The term “optimiser” broadly refers to a system, algorithm, or process designed to improve the efficiency, performance, or resource usage of a given target, whether software, hardware, or business workflow
- In computer science, optimisers are foundational in compilers, runtime environments, and performance engineering, aiming to reduce execution time, memory footprint, or energy consumption
- Key developments and current state
- Modern optimisers increasingly leverage machine learning and real-time analytics to adapt to dynamic workloads and user needs
- The field has expanded beyond traditional code optimisation to include cloud resource management, business process automation, and energy efficiency
- Academic foundations
- Rooted in algorithmic complexity theory, systems engineering, and operations research
- Influential early work includes Aho and Ullman’s compiler design principles and Knuth’s analysis of algorithms
