Market basket data
| Глоссарий по искусственному интеллекту |
A common problem in data mining deals with a type of data known as market basket data. this is data where each record consists of a list of items that were purchased simultaneously or otherwise naturally grouped. the typical example would be purchase records from a retail store although the techniques could be applied in many other diverse problems (e.g., medical symptoms). this label is commonly used when the purpose of the analysis is to discover association rules or dependency rules. the former are simply rules that state if item a is in the "basket," then item b is also in the basket, with two measures, the support (the percentage of cases that have both a & b) and the confidence (the percentage of cases with b among those that have a). the latter are a generalization of association rules that are covered elsewhere. see also: association rules, dependence rule.

Association, английский
- Ассоциация, объединение, союз
- Two variables are associated if some of the variability of one can be accounted for by the other. in a scatterplot of the two variables, if the scatter in the values of the variable plotted on the vertical axis is smaller in narrow ranges of the variable plotted on the horizontal axis (i.e., in vertical "slices") than it is overall, the two variables are associated. the correlation coefficient is a measure of linear association, which is a special case of association in which large values of one variable tend to occur with large values of the other, and small values of one tend to occur with small values of the other (positive association), or in which large values of one tend to occur with small values of the other, and vice versa (negative association).

- In psychology, the cognitive connection between two or more concepts or ideas such that the presence of one tends to evoke the others. in sociology, the process by which people become allied to one another and form groups as the result of such alliances. in statistics, the cooccurance of two or more events with a probability above what would be expected by chance. dissociation is the logical complement of the statistical concept of association.
- A relationship between peer objects.
- In performancepoint planning business modeler, the relationship between a source model and a destination model for the purpose of manipulating the arrangement of interpretive data and aggregating the corresponding numerical measurements.
- The definition of a relationship between entity types.
- The link between a collection and a deployment.
- The mapping of a file extension (for example, .mp3) or protocol (for example, http) to a programmatic identifier (progid). this mapping is stored in the registry as a per-user setting with a per-computer fallback. applications that participate in the default programs system set the association mapping for the file extension or protocol to point to the progid keys that they own.
- The state of being totally connected to, or experiencing, an event, mental or external. the opposite is dissociation (sometimes, disassociation), which is being an objective observer.

Dependence, английский

- The fact of needing the support of something or someone such as a carer, nurse or doctor, or of being addicted to a drug
- Зависимость
- A set of attributes is said to be dependent if the state of a subset of the attributes affects the (distribution of) the state of the remaining attributes. for two variables, the attributes x and y are dependent if pr(x y) pr(x)pr(y), where pr(.) is a probability measure. if the converse holds (pr(x y)= pr(x)pr(y)), then the attributes are said to be independent.
- The state in which one entity relies upon specific hardware, software, or specific events for its own definition or functionality.

Sparse data problem, английский
A common problem for statistical and other empirical learning techniques is the sparse data problem. if the learning is limited to simple frequency counts of "events" in the training sets, the model will always behave poorly on new input that introduces related but "new" events. the more detailed the original model becomes, the more data required to learn (estimate) the various parts of the model; therefore, the amount of data supporting any one part becomes increasingly sparser. practically speaking, this simply means that the input data can rarely cover all possible cases. one approach for dealing with this problem is use of theoretical knowledge to add structure to the empirical model or the use of smoothing techniques to "fill in" the missing data.
Object oriented language, английский
A computer language that treats data and data structures as objects, and which can send and receive messages or commands, and act upon those. this differs from traditional procedural languages, where the results are obtained through a series of procedures that is applied to the data.
