Problem reduction

In computability theory and computational complexity theory, a reduction is an algorithm for transforming one problem into another problem. A sufficiently efficient reduction from one problem to another may be used to show that the second problem is at least as difficult as the first. Intuitively, problem A is reducible … Visa mer There are two main situations where we need to use reductions: • First, we find ourselves trying to solve a problem that is similar to a problem we've already solved. In these cases, often a quick way of solving … Visa mer A reduction is a preordering, that is a reflexive and transitive relation, on P(N)×P(N), where P(N) is the power set of the natural numbers. Visa mer • To show that a decision problem P is undecidable we must find a reduction from a decision problem which is already known to be undecidable to P. That reduction function must be a Visa mer As described in the example above, there are two main types of reductions used in computational complexity, the many-one reduction and … Visa mer • Gadget (computer science) • Many-one reduction • Parsimonious reduction Visa mer Webb13 juni 2024 · The most well-known dimensionality-reduction technique are ones that implement the linear transformation, such as: · Principal component analysis (PCA). PCA, an unsupervised machine learning algorithm, reduces the dimensions of a dataset whilst retaining as much information as possible.
