Support-vector machine | SVMs belong to a family of generalized linear classifiers and can be interpreted as an extension of the perceptron. They can also be considered a special case of Tikhonov regularization. A special property is that they simultaneously minimize the empirical classification error and maximize the geometric margin; hence t... | wikipedia |
Attachment disorder | In the absence of officially recognized diagnostic criteria, and beyond the ambit of the discourse on a broader set of criteria discussed above, the term attachment disorder has been increasingly used by some clinicians to refer to a broader set of children whose behavior may be affected by lack of a primary attachment... | wikipedia |

Behavioural ecology | Sexual conflict, in some form or another, may very well be inherent in the ways most animals reproduce. Females invest more in offspring prior to mating, due to the differences in gametes in species that exhibit anisogamy, and often invest more in offspring after mating. This unequal investment leads, on one hand, to i... | wikipedia |

Inclusion-exclusion principle | Given finite sets A and B, how many surjective functions (onto functions) are there from A to B? Without any loss of generality we may take A = {1, ..., k} and B = {1, ..., n}, since only the cardinalities of the sets matter. By using S as the set of all functions from A to B, and defining, for each i in B, the propert... | wikipedia |
Euclidean Algorithm | Another inefficient approach is to find the prime factors of one or both numbers. As noted above, the GCD equals the product of the prime factors shared by the two numbers a and b. Present methods for prime factorization are also inefficient; many modern cryptography systems even rely on that inefficiency.The binary GC... | wikipedia |
Parenting style | Although research on attachment theory has focused on infancy and early childhood, research has shown that the relationship between teens and their parents can be affected depending on whether they have a secure or insecure attachment between them. A parent's interaction with their child during infancy creates an inter... | wikipedia |
Homozygous dominant | When the red homozygous flower is paired with the white homozygous flower, the result yields a pink snapdragon flower. The pink snapdragon is the result of incomplete dominance.

Quantitative trait | After the conclusion of the Human Genome Project in 2001, it seemed that the sequencing and mapping of many individuals would soon allow for a complete understanding of traits’ genetic architectures. However, variants discovered through genome-wide association studies (GWASs) accounted for only a small percentage of pr... | wikipedia |
Spurious solution | The reason is that x is actually not in general the positive square root of x2. If x is negative, the positive square root of x2 is -x. If the step is taken correctly, it leads instead to the equation: x 2 = 4 . {\displaystyle {\sqrt {x^{2}}}={\sqrt {4}}.} | wikipedia |
Distinct degree factorization | In mathematics and computer algebra the factorization of a polynomial consists of decomposing it into a product of irreducible factors. This decomposition is theoretically possible and is unique for polynomials with coefficients in any field, but rather strong restrictions on the field of the coefficients are needed to... | wikipedia |
Population Ecology | An important concept in population ecology is the r/K selection theory. For example, if an animal has the choice of producing one or a few offspring, or to put a lot of effort or little effort in offspring -- these are all examples of trade-offs. In order for species to thrive, they must choose what is best for them, l... | wikipedia |
Ecology | Many kinds of insects and invasive species exhibit r-selected characteristics.

Humans and elephants are examples of species exhibiting K-selected characteristi... | wikipedia |
Kotzig transformations | In graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex. They were first discussed by Leonhard Euler while solv... | wikipedia |
Plant genetics | In plant breeding, people create hybrids between plant species for economic and aesthetic reasons.
