Station-keeping
Station-keeping is the maintenance of a satellite's assigned orbital position against natural perturbations: geostationary satellites burn propellant to stay within a control box of about ±0.1° in longitude and inclination.
Stationary wavelet transform
The stationary wavelet transform (SWT), also called the undecimated wavelet transform, is a variant of the discrete wavelet transform that omits downsampling, restoring translation invariance and improving denoising.

Statistical classification
Statistical classification, also called pattern classification, is the machine learning task of predicting which class an example belongs to, using methods such as logistic regression and support vector machines.
Statistical energy analysis
Statistical energy analysis (SEA) is a vibro-acoustics method predicting high-frequency vibration and sound by balancing energy between coupled subsystems, used on aerospace vehicles and other large lightweight structures.
Statistical learning theory
Statistical learning theory, also known as statistical machine learning, is the mathematical framework studying when algorithms trained on finite samples perform well on new, unseen data.
Statistical machine translation
Statistical machine translation is an approach to machine translation that selects the most probable translation using probability models estimated from large collections of parallel text rather than hand-written rules.
Statistical relational learning
Statistical relational learning (SRL) is a branch of machine learning that combines probabilistic models with logical representations to learn and reason over structured, linked data such as networks and databases.
Statistical shape model
A statistical shape model is a computational method representing the variability of anatomical or object shapes, used to segment structures in medical images via a mean shape and principal modes of variation.
Statistical static timing analysis
Statistical static timing analysis (SSTA) is a method for verifying digital circuit timing that models gate and interconnect delays as probability distributions instead of worst-case numbers.
