Beam search
| Глоссарий по искусственному интеллекту |
Many search problems (e.g., a chess program or a planning program) can be represented by a search tree. a beam search evaluates the tree similarly to a breadth-first search, progressing level by level down the tree but only follows a best subset of nodes down the tree, prunpage 28 ing branches that do not have high scores based on their current state. a beam search that follows the best current node is also termed a best first search. see also: best first algorithm, breadth-first search.

Beam, английский
- Poutre;balancier
- Structural member, other than a triangulated frame, which supports load primarily by its internal resistance to bending.
- A structural member transversely supporting a load. a structural member carrying building loads (weight) from one support to another. sometimes called a "girder".
- The maximum breadth or the greatest width of a ship
- The width of a vessel at the widest point, or a point alongside the ship at the midpoint of its length.
- The width of a ship. also called breadth.
- A collection of rays that may be parallel, convergent, or divergent.
- A structural member supporting a load applied transversely
- A group of parallel rays of light.

- A transverse structural member that stiffens and supports a portion of the deck.
- The widest part of a boat.
- A cylinder of wood or metal, usually with a circular flange on each end, on which warp yarns are wound for slashing, weaving, and warp knitting.

Beam angle, английский
If you`re into reading light-performance data, beam angle is the point at which the intensity of a source drops to 50% of maximum (center reading) measured in degrees of the full angle. simply: how wide?
Beam angle (rt), английский

Binning, английский
Many learning algorithms only work on attributes that take on a small number of values. the process of converting a continuous attribute, or a ordered discrete attribute with many values into a discrete varipage 33 able with a small number of values is called binning. the range of the continuous attribute is partitioned into a number of bins, and each case continuous attribute is classified into a bin. a new attribute is constructed which consists of the bin number associated with value of the continuous attribute. there are many algorithms to perform binning. two of the most common include equi-length bins, where all the bins are the same size, and equiprobable bins, where each bin gets the same number of cases. see also: polya tree.
Constraint propagation, английский
Many systems have a series of constraints on the values or properties. if these can be represented by a network of relationships, the systems can propagate the local constraints throughout the system to achieve global consistency. generally, when a stable system is updated with new data or a query, the constraints can be iteratively fired to cascade through the system until the values of the system reach a stable state. see also: relaxation procedures.
