At a young age, many of us have looked up to the night sky wondering what lies beyond the limits of what can be seen from Earth. In earlier centuries, all that was known to man was the Earth, its satellite, which is the moon, the sun, and the stars that sparkled in the night sky. As time progressed, astronomers began discovering more planets, which then expanded into discovering that earth is a part of one of the many solar systems within our own galaxy, and eventually we discovered billions of other

2000). At the beginning, all of the documents are in one partition. Then the following procedure will be repeated K 1 times to obtain K clusters. Initially the partition to be broken is selected. In the standard algorithm the partition with maximal cardinality is chosen, but in this research the one with maximal intra scatter has been selected as a low quality cluster. Intra

B. Descriptive techniques - Clustering- It involves identifying clusters and grouping similar objects together in each cluster. The main focus is on evaluating and implementing Partitioned (K-means) algorithms, other clustering methods include Hierarchical (CURE, BIRCH), Grid – based (STING, WaveCluster), Model-based (Cobweb), and Density based (DBSCAN). Author [31] presented work to enhance the performance of one of the most well-known pop ular clustering algorithms (K-mean) to produce near-optimal

In cluster sampling, instead of selecting all the subjects from the entire population right off, the researcher must take several steps in order to gather his or her sample population. First, the researcher must select various groups or clusters, and then from each cluster, the researcher begins to choose the individual subjects by either simple random or systematic random sampling. The researcher can even opt to include the entire cluster and not just a subset from it depending on the design study

Sampling According to Schutt (2008), sampling is defined as a subset of population used in a study to be a representation of the population as a whole. My final project is a pre-hire assessment which analyzes potential risky pattern behaviors and emotions in the work place. One of the most important considerations related to sampling that will need to be addressed in my final project is defining the population that will be taking the assessment. According to Frankfort-Nachmias and Nachmias (2008)

During our data collection, the original method of random assignment we planned to use was not plausible, since it required all 60 of our subjects at a time and we had two days of data collection. Instead, we changed our method slightly and gathered people in groups of four and assigned each person a number from the random number generator in our calculator. If it was an even number they received gum and if it was an odd number they did not. Some ways there could have been a potential bias is if

Recruitment and use of children in war is one of the six grave violations against children in situations of conflict. Currently, there are over 300,000 child soldiers being exploited in battle, while six million have been gravely injured or are now permanently disabled. Additionally, there are about 20 million boys and girls that have been displaced and are refugees in surrounding countries due to the gross violations of conflict and human rights. The role of children in armed conflict is not restricted

Question 1. 1.1 Types of interview: • Telephone interview • Face-to-face interview • Panel interview • Group interview • Sequential interview • Lunch/dinner interview • Formal/informal interview  Telephone interview: Regularly companies ask for a phone interview before welcoming you in for a face-to-face interview so as to show sign of improvement comprehension of the kind of applicant you are.  Face-to-face interview: In face to face interview done by you and one of company employee or two

that will find the clusters in the huge data is a big task. As a result we are using practical categorical representative named Node Importance Representative (NIR). It represent clusters by measuring the importance of each attribute value in the clusters. Based on this we propose Drift Concept Detection (DCD). 1.3 DRIFT CONCEPT DETECTION (DCD) In DCD, the incoming categorical data points at the present sliding window are first allocated into the corresponding proper cluster at the last clustering
