Algorithmic rules

The main purpose of this paper is to identify mainstream views to develop students thinking ability. For each view, we provide a process of researching, discovering, setting up and implementing algorithmic rules, quasi-algorithmic rules by giving out examples.

In this paper we present two parallel algorithms for mining association rules that are well suited for distributed memory parallel computers. The algorithms are developed based on FP-growth method. The first algorithm is a task parallel formulation using a static load balancing technique. The second algorithm improves upon the first algorithm by dynamically balancing the load when the static task assignment leads to load imbalance.

This paper proposes a method for mining fuzzy association rules using compressed database. We also use the approach of Hedge Algebra (HA) to build the membership function for attributes instead of using the normal way of fuzzy set theory. This approach allows us to explore fuzzy association rules through a relatively simple algorithm which is faster in terms of time, but it still brings association rules which are as good as the classical algorithms for mining association rules.

This paper describes a model of syntactical analysis. It shows first how a context-free grammar formalism can be modified in order to reduce the number of rules required by a natural language, and second, how this formalism can be extended to the handling of some non-contextfree phenomena. The description of the algorithm is also given.

The purpose of this paper is to examine the oft-repeated assertion regarding the efficiency of a "simple parsing algorithm" combinable with a variety of different grammars written in the form of appropriate tables of rules.

Problems of machine translation have been investigated in the Soviet Union since 1955.1 A number of groups are carrying out theoretical and experimental work in the area of machine translation. In the Institute of Precision Mechanics and Computer Technology of the Academy of Sciences of the USSR (ITM and VT) dictionaries and codes of rules (algorithms) have been compiled for machine translation from English, Chinese, and Japanese into Russian; and a GermanRussian algorithm is being worked out.

Cannot stop malicious packets from getting into an edge network Authentication? Can determine whether an incoming IP packet comes from a trusted user However, not all host computers have resources to run authentication algorithms Host computers managed by different users with different skill levels.

Given a set of transactions, find rules that will predict the occurrence of an item based on the occurrences of other items in the transaction. Given a set of transactions T, the goal of association rule mining is to find all rules having support ≥ minsup threshold confidence ≥ minconf threshold Brute-force approach: List all possible association rules Compute the support and confidence for each rule Prune rules that fail the minsup and minconf thresholds  Computationally prohibitive!...

Given a connected, undirected graph, a spanning tree of that graph is a subgraph that is a tree and connects all the vertices together. A single graph can have many different spanning trees. We can also assign a weight to each edge, which is a number representing how unfavorable it is, and use this to assign a weight to a spanning tree by computing the sum of the weights of the edges in that spanning tree.
