Search model

Each of these two QSAR model searches led to pools of several thousands of statistically valid linear equations, expressing the estimate of the Cox2 pICso value as linear combinations of molecular descriptors selected by a Genetic Algorithm (GA) [57,...

Object Relational Database. A relational database in which data can be collected and combined with methods to fit an object oriented model. Searching in the database is conducted in the context of the objects and their methods, rather than the raw data fields and stored procedures. There is usually considerable overhead in building, maintaining, and using an object relational database, so this type of organization has not so far been widely used in chemical or biological databases. 

A variable selection method proposed to decrease the huge number of models that must be evaluated by all subset model searching. 

In most production system models, search and control are the essential mechanisms that govern the actions taken by the models. Winston (1977) very succinctly describes these two mechanisms. He explains that search has to do with how the system interacts with its external environment and control has to do with how it utilizes its internal components (1977, p. 155). Thus, one has strategies for search and decisions about control. From their descriptions, one sees that Newell s models are primarily concerned with search strategies, because they focus on searching the problem spaces, whereas Anderson s model emphasizes control, because it focuses on decisions of pattern matching. 

On the other hand, several investigators (6, 7) have taken another approach, based on pattern recognition. These dichotomous models search for agreement between dependent variables i.e., whether a chemical entity or substructure can be associated with a particular toxic property. For example, certain N-nitrosamine groups are associated with tumors in animals. Since this consideration is not dependent on a relationship between the endpoint and the dose, the quantitative term is dropped from QSAR and the effort simply named SAR. This approach is best expressed by the dependent equation ... 

Rl, 1, 8 specifies that motif number one is a palindrome. The first eight conserved positions will be combined with the reverse complements of the last eight positions to form the palindromic model. When using a palindromic model, searching for sites on the reverse complement of the input sequence data should be disabled... 

Sampling assumes that relationships and features appearing in the whole data set will be tractable as long as they are sufficiently represented in the sample. This makes it an ideal tool for model searching and building. However, it is not suited in situations in...

Some results of the use of the ESI approach for liquid-liquid equilibrium data evaluation are presented to demonstrate this possibility for chemical model search. All calculations were performed with EXLET 92 program [71], accomplished with complete statistical analysis of residuals and several advanced minimizing routines in addition to pit mapping of LETAGROP.

Fast-forward to today. When 1 recently bought a car, 1 did all the research online over the course of a few weeks. 1 was able to compeire models, search reviews, read forums, and see what my friends had to say. I was able to pick the exact model 1 wanted, with the exact features. And I was able to figure out exactly what 1 should pay for it. 1 negotiated the price cind the financing online. The first — and only time — 1 actually spoke with a dealer was to sign the paperwork and take delivery.
