Cross-project Defect Prediction Using A Connectivity-based Unsupervised Class...Feng Zhang
Defect prediction on projects with limited historical data has attracted great interest from both researchers and practitioners. Cross-project defect prediction has been the main area of progress by reusing classifiers from other projects. However, existing approaches require some degree of homogeneity (e.g., a similar distribution of metric values) between the training projects and the target project. Satisfying the homogeneity requirement often requires significant effort (currently a very active area of research).
An unsupervised classifier does not require any training data, therefore the heterogeneity challenge is no longer an issue. In this paper, we examine two types of unsupervised classifiers: a) distance-based classifiers (e.g., k-means); and b) connectivity-based classifiers. While distance-based unsupervised classifiers have been previously used in the defect prediction literature with disappointing performance, connectivity-based classifiers have never been explored before in our community.
We compare the performance of unsupervised classifiers versus supervised classifiers using data from 26 projects from three publicly available datasets (i.e., AEEEM, NASA, and PROMISE). In the cross-project setting, our proposed connectivity-based classifier (via spectral clustering) ranks as one of the top classifiers among five widely-used supervised classifiers (i.e., random forest, naive Bayes, logistic regression, decision tree, and logistic model tree) and five unsupervised classifiers (i.e., k-means, partition around medoids, fuzzy C-means, neural-gas, and spectral clustering). In the within-project setting (i.e., models are built and applied on the same project), our spectral classifier ranks in the second tier, while only random forest ranks in the first tier. Hence, connectivity-based unsupervised classifiers offer a viable solution for cross and within project defect predictions.

Homily: The Solemnity of the Most Holy Trinity Sunday 2024.docxJames Knipper
Countless volumes have been written trying to explain the mystery of three persons in one true God, leaving us to resort to metaphors such as the three-leaf clover to try to comprehend the Divinity. Many of us grew up with the quintessential pyramidal Trinity structure of God at the top and Son and Spirit in opposite corners. But what if we looked at this ‘mystery’ from a different perspective? What if we shifted our language of God as a being towards the concept of God as love? What if we focused more on the relationship within the Trinity versus the persons of the Trinity? What if stopped looking at God as a noun…and instead considered God as a verb? Check it out…

The Book of Joshua is the sixth book in the Hebrew Bible and the Old Testament, and is the first book of the Deuteronomistic history, the story of Israel from the conquest of Canaan to the Babylonian exile.
In Jude 17-23 Jude shifts from piling up examples of false teachers from the Old Testament to a series of practical exhortations that flow from apostolic instruction. He preserves for us what may well have been part of the apostolic catechism for the first generation of Christ-followers. In these instructions Jude exhorts the believer to deal with 3 different groups of people: scoffers who are "devoid of the Spirit", believers who have come under the influence of scoffers and believers who are so entrenched in false teaching that they need rescue and pose some real spiritual risk for the rescuer. In all of this Jude emphasizes Jesus' call to rescue straying sheep, leaving the 99 safely behind and pursuing the 1.
