Example Of Data Processing - 8068 Words

Data Processing Following the creation of the sample, I applied the KNN, SVM, CDA, and k-means pattern recognition algorithm treatment to every member of the sample of the CDAnalysis program and recorded whether the pattern recognition algorithm correctly identified the class of the exposure. If the pattern recognition algorithm determined the class of the exposure to be the same as the same class from which the Cyranose 320 sampled the exposure, then the classification for the exposure was correct. I recorded the correct and incorrect classifications for all exposures from the sample of two hundred exposures and calculated the proportion of the classifications that were correct. I kept this data in an excel sheet for every exposure of†¦show more content†¦The null hypotheses stated that there is no difference in the classification (or detection) of common indoor fungal contaminants for different electronic nose pattern recognition algorithms: Ï€1 = Ï€2 = Ï€3 = Ï€4. The alte rnative hypotheses stated that there is a difference in the classification (or detection) of common indoor fungal contaminants for different electronic nose pattern recognition algorithms: Ï€a ≠  Ï€b; 1 ≠¤ a, b ≠¤ 4. I established the significance level at the commonly accepted ÃŽ ± level of 0.05 and used three degrees of freedom when establishing the chi-squared statistic. The rejection of the null hypotheses would have resulted in the post hoc performance of six separate pairwise McNemar tests between combinations of two treatments to locate significant differences between the classification accuracies of specific pairs of treatments. The assumptions of McNemar tests included a dichotomous independent variable (two pattern recognition algorithms) or treatments and a dichotomous dependent variable (â€Å"correct† or â€Å"incorrect†) that were mutually exclusive (Laerd Statistics, n.d.). The McNemar test also assumed a randomized sample, which I covered in Cochran’s Q test. Assumptions Assumptions of studies were factors that were out of control but still justified by the researcher (Simon, 2011). A research assumption of this study required that the lab-grownShow MoreRelatedTps - a Transaction Processing System1462 Words   |  6 Pagesothers involve recording or retrieving data (making a booking, enrolling a student at university looking up results etc) Most individual transactions are relatively simple, but in most organisations, there are very large numbers of them - so speed and efficiency are important considerations.

But with such a huge amount of data, there come many performance challenges. If Big Data systems cannot be used to make or forecast critical business decisions, or provide insights into business values hidden under huge amounts of data at the right time, then these systems lose their relevance. This article talks about some of the critical performance considerations in a technologyRead MoreImpact Of Information On The Transport Sector Of Bangladesh Essay1296 Words   |  6 Pages30km faraway from port city Chittagong.

The primary problem is that big data cannot be uploaded and made to run the aggregation exercise through full table scans as it takes prohibitive time. Big data needs to be pre-processed before it is uploaded to the analysis box. The aim of this project is to study and research various data pre-processing techniques used in practiceRead MoreArticle On Data Mining With Big Data1734 Words   |  7 Pages(Class ID: 46) Article: Data Mining with Big Data (Paper-1) This paper addresses the complications being faced by Big Data because of increase in the volume, complexity of data and due to multiple sources, which produces large number of data sets.
