Kermit Roosevelt
Kermit Roosevelt (1889-1943), second son of President Theodore Roosevelt, was an author, explorer, and soldier who served in both British and U.S. armies in two world wars, founded the Roosevelt Steamship Company, and died by suicide in Alaska in 1943; distinct from his son Kermit Roosevelt Jr., the CIA officer.
Kermit Roosevelt Jr.
Kermit Roosevelt Jr. (1916–2000), called Kim, grandson of Theodore Roosevelt, was the CIA Near East division chief who ran Operation TPAJAX on the ground, overthrowing Mosaddeq in Iran in August 1953, later writing the controversial memoir Countercoup.
Kermit the Frog
Kermit the Frog, the Muppet created by Jim Henson in 1955 on Sam and Friends, originally lizard-like with ping-pong ball eyes; became a frog, starred on Sesame Street and The Muppet Show, sang Bein' Green.
Kermit V. Lipez
Kermit V. Lipez, also known as Kermit Victor Lipez, is an American jurist serving as a senior judge of the First Circuit since 2011, appointed by President Clinton in 1998.
Kermit Washington
Kermit Washington was an NBA power forward who played for the Lakers; he is known for being an All-Star and for his 1977 punch against Rudy Tomjanovich.
Kern County child abuse cases
Kern County child abuse cases: 1980s Bakersfield child molestation "ring" prosecutions led by DA Ed Jagels, built on coercive child interviews; most convictions reversed, defendants exonerated, county later paid settlements.
Kern County, California
Kern County, California: county at the southern Central Valley and Mojave Desert, seat Bakersfield, founded 1866. Over 70 percent of state oil output, a top-five US farm county, population about 927,000.
Kern Island Canal
The Kern Island Canal is an irrigation canal in Kern County, California, diverting Kern River water south of Bakersfield to farmland on the former Kern Lake bed.
Kern River
Kern River: about 165-mile southern Sierra Nevada river flowing from near Mount Whitney to Bakersfield; only major Sierra river draining south; subject of Lux v. Haggin and Isabella Dam.
Kern River Gas Pipeline
The Kern River pipeline is an interstate natural gas pipeline running about 1,700 miles from southwestern Wyoming through Utah and Nevada to California, in service since 1992.
Kern River Oil Field
The Kern River Oil Field is a giant heavy-oil field east of Bakersfield, California, discovered in 1899, with more than 2.2 billion barrels produced largely by steam flooding since 1964.
Kernavė Archaeological Site (Cultural Reserve of Kernavė)
Kernavė Archaeological Site (Cultural Reserve of Kernavė) is a UNESCO World Heritage site in the Neris valley near Vilnius, preserving about 10,000 years of settlement, hill forts, and a medieval town.
Kernel (algebra)
The kernel (also called the kernel of a homomorphism) in algebra is the set of elements a homomorphism sends to zero, a submodule measuring injectivity.
Kernel (image processing)
A kernel in image processing is a small matrix of coefficients slid across an image and combined with its pixels by convolution to produce each output pixel of the filtered result.
Kernel (linear algebra)
The kernel of a linear map, also called its null space, is the set of all domain vectors the map sends to zero; it is a linear subspace of the domain.
Kernel (operating system)
The kernel, also called the operating system kernel, is the core program of an operating system that runs in privileged hardware mode, controlling memory, devices, and program isolation.
Kernel (statistics)
In statistics, a kernel is a weighting function used to build nonparametric estimates from data, introduced for density estimation by Rosenblatt in 1956; the word also names Markov transition kernels.
Kernel association test
A kernel association test is a set-based statistical test in genetics that regresses a trait on many variants in a genomic region at once; SKAT is the best known.
Kernel clustering
Kernel clustering is a family of clustering methods that groups data points by pairwise similarity with a kernel function, capturing non-linearly separable clusters that plain k-means misses.
Kernel density estimation
Kernel density estimation, or Parzen windowing, is a nonparametric statistical method for estimating the probability density function of a distribution from data by placing a smooth kernel around each observed point.
Kernel method
Kernel methods, also called kernel machines, are machine learning algorithms that operate on a matrix of pairwise similarities, letting linear algorithms handle nonlinear patterns in high-dimensional feature spaces.
Kernel panic
A kernel panic is the action an operating system kernel takes on an unrecoverable internal error: it prints a diagnostic message, then halts or reboots the machine.
Kernel PCA
Kernel PCA, or kernel principal component analysis, is a nonlinear extension of PCA that uses the kernel trick, introduced by Schölkopf, Smola, and Müller in 1998.
Kernel principal component analysis
Kernel principal component analysis (kernel PCA) is a nonlinear dimensionality reduction method that performs PCA in a high-dimensional kernel-defined feature space, introduced by Schölkopf, Smola, and Müller in 1998.
Kernel regression
Kernel regression is a nonparametric method for estimating a regression function from data without a fixed parametric form, using weighted averages such as the Nadaraya–Watson estimator.
Kernel ridge regression
Kernel ridge regression (KRR) is a nonlinear regression method that combines ridge regression with the kernel trick, yielding a closed-form predictor used in molecular property prediction and genomic prediction.
Kernel trick
The kernel trick is a machine learning technique that lets algorithms operate in high-dimensional feature spaces by replacing inner products with a kernel function, as in support vector machines.
Kernel-based Virtual Machine
Kernel-based Virtual Machine, or KVM, is a virtualization module built into the Linux kernel that turns the kernel into a hypervisor, included in mainline Linux since kernel version 2.6.20.
Kernel-level anti-cheat
Kernel-level anti-cheat is game-security software that runs as a signed driver in the operating system kernel, adopted because cheats had moved into the kernel themselves; major systems include Riot Vanguard, Easy Anti-Cheat, and BattlEye.
Kernelization
Kernelization is a framework in parameterized complexity theory for analyzing provably efficient and provably effective data reduction for NP-hard problems, originating in the early 1990s.
