Knowledge-processing technology can be used to aid engineering design. This paper presents the application of an id3 algorithm in knowledge acquisition for the tolerance design of injection-molded parts. The overall structure of a knowledge-based system for tolerance design is briefly illustrated. After a classification of factors that influence tolerance has been made, some key attributes for collecting knowledge cases are studied through fuzzy representation and processing. The detailed procedure of utilizing an id3 algorithm for tolerance-related knowledge acquisition is introduced, including calculating the information gain measure (entropy) and generating the final decision tree. The method can be easily applied to other engineering areas and the result has great value in practice. The advantages and disadvantages of this method are discussed in Section 5.

Data mining techniques play an important role in clinical decision making, which provides physicians with accurate, reliable and quick predictions through building different models. This paper presents an improved classification approach for the prediction of diseases based on the classical Iterative Dichotomiser 3 (id3) algorithm. The improved id3 algorithm overcomes multi-value bias problem when selecting test/split attributes, solves the issue of numeric attribute discretization and stores the classifier model in the form of rules by using a heuristic strategy for easy understanding and memory savings. Experiment results show that the improved id3 algorithm is superior to the current four classification algorithms (J48, Decision Stump, Random Tree and classical id3) in terms of accuracy, stability and minor error rate.

In this paper, we assume that a single pedestrian is a single blob, and define the representative properties of blobs to selection between merge and split of blobs. And we collect attribute information of the blob and make decision tree by using the id3 algorithm. Next, we experimented for dividing the decision tree by directing the status of merge and split, as a result, it is possible to generate a pedestrian trajectory of the individual.

Globally, the second most common cause of death for female cancer patients is breast cancer. In the United States, about 11,000 females aged below 40 are diagnosed with invasive breast cancer each year. Early detection of breast cancer is the foundation for preventing the progression of the disease, and the diagnosis can be conducted using intelligent systems for quicker detection. Based on the FUZZYDBD method and bootstrap aggregation (bagging) technique, the Bagging fuzzy-id3 algorithm (BFid3) was proposed for this study. This method combined the techniques of the fuzzy system, id3 algorithm and bagging. For BFid3's data fuzzification, the automatic fuzzy database definition method, known as the FUZZYDBD method, would assist in developing the fuzzy database. One of the weaknesses of the id3 algorithm is its incapability to handle continuous data. The problem was resolved via the linguistic variable replacement and data fuzzification in the BFid3. Meanwhile, this paper's implementation of the bagging technique improved the generalization ability and reduced overfitting. Additionally, BFid3 was verified through an extensive comparison with several existing methods to investigate the competency of the proposed method. The study identified that BFid3 was proficient in breast cancer classification.

For the problems of large computational complexity and splitting attribute selection inclining to choose the attribute which has many values in id3 algorithm, this paper presents an improved algorithm based on the Information Entropy and Attribute Weights. In the improved algorithm, it has been combined with the Taylor's theorem and Attribute Similarity theorem to simplify the calculation of Entropy and determine the attribute importance weights, and an amended information gain is accomplished as the attribute selection criteria. The results of experiment comparison proved that the algorithm can improve the speed of classification, significantly improve the accuracy of rules, and derive more practical rules for applications.
