  2. Data build tool - Wikipedia

    en.wikipedia.org/wiki/Data_build_tool

    Dbt has the goal of allowing analysts to work more like software engineers, in line with the dbt viewpoint. [11] Dbt uses YAML files to declare properties. seed is a type of reference table used in dbt for static or infrequently changed data, like for example country codes or lookup tables), which are CSV based and typically stored in a seeds ...

  3. Data model - Wikipedia

    en.wikipedia.org/wiki/Data_model

    Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.

  4. Predictive modelling - Wikipedia

    en.wikipedia.org/wiki/Predictive_modelling

    For example, a large consumer organization such as a mobile telecommunications operator will have a set of predictive models for product cross-sell, product deep-sell (or upselling) and churn. It is also now more common for such an organization to have a model of savability using an uplift model. This predicts the likelihood that a customer can ...

  5. Graphical model - Wikipedia

    en.wikipedia.org/wiki/Graphical_model

    An example of a directed, cyclic graphical model. Each arrow indicates a dependency. In this example: D depends on A, B, and C; and C depends on B and D; whereas A and B are each independent. The next figure depicts a graphical model with a cycle. This may be interpreted in terms of each variable 'depending' on the values of its parents in some ...

    en.wikipedia.org/wiki/Marsha_M._Linehan

    Marsha M. Linehan (born May 5, 1943) is an American psychologist and author. She is the creator of dialectical behavior therapy (DBT), a type of psychotherapy that combines cognitive restructuring with acceptance, mindfulness, and shaping.

  7. Constraint satisfaction problem - Wikipedia

    en.wikipedia.org/.../Constraint_satisfaction_problem

    The classic model of Constraint Satisfaction Problem defines a model of static, inflexible constraints. This rigid model is a shortcoming that makes it difficult to represent problems easily. [33] Several modifications of the basic CSP definition have been proposed to adapt the model to a wide variety of problems.

  8. NP (complexity) - Wikipedia

    en.wikipedia.org/wiki/NP_(complexity)

    Euler diagram for P, NP, NP-complete, and NP-hard set of problems. Under the assumption that P ≠ NP, the existence of problems within NP but outside both P and NP-complete was established by Ladner. [1] In computational complexity theory, NP (nondeterministic polynomial time) is a complexity class used to classify decision problems.

  9. Curse of dimensionality - Wikipedia

    en.wikipedia.org/wiki/Curse_of_dimensionality

    There is an exponential increase in volume associated with adding extra dimensions to a mathematical space.For example, 10 2 = 100 evenly spaced sample points suffice to sample a unit interval (try to visualize a "1-dimensional" cube) with no more than 10 −2 = 0.01 distance between points; an equivalent sampling of a 10-dimensional unit hypercube with a lattice that has a spacing of 10 −2 ...
