Sensitivity means probability that the algorithms can correctly predict non malignancy and specificity means probability to correctly predict malignancy. Predictive data mining is the most common type of data mining and one that has the most direct business applications. Mi- lovic et al. Confusion Matrix for both training and validation data is shown in Table [5]. In the case of categorical variables, N-1 neurons are used to represent the N categories of the variable.

The second tool used is WEKA3.

Lift and gain values are especially use- ful when a model is being used to target prioritize marketing efforts. The other measures used by the tool to evaluate the model are as fol- lows:. Early carcinomas are presumably asymptotic and en- suing signs are regularly misjudged in light of the fact that they imitate numerous benevolent lesions and the distress is negligible. It is a Java based open source tool cre- ated by researchers at the University of Waikato in New Zea- land [11].

The first criteria on which both the tools are evaluated are receiver operating characteristic ROC.

Oral tumor presenting with nodal metastases would appear to have a less favorable prognosis [25]. The DTREG can be used to predict values for future ob- servations and also has full support for time series analysis. Therefore, the dtrey of oral cancer is primarily that of pathogenesis, diag- nosis ctreg management of squamous cell carcinoma originat- ing from oral muscular surface [24].

Clas- sification technique is used for analysis, category weights are distributed over entire data file, misclassification costs are equal and variable weights are also equal.

ROC is a graph that demon- strates the performance of a binary classifier model. Section 5 presents the experimental results of both the tools and section 6 compares the performance of the tools. Most oral sores are benign, yet many have a manifestation that may be effectively befuddled with threatening lesions and some are considered pre- malignant because they have been statistically correlated with subsequently cancerous changes [23].

What are they talking about? Computational Linguistics, 22 2pp. Number of layers is 3 input, hidden and output.

It is a robust measure in comparison to simple percent agreement calculation since kappa dtreh takes into ac- count the agreement occurring by chance [28][29]. Sensitivity means probability that the algorithms can correctly predict non malignancy and specificity means probability to correctly predict malignancy.

The performance of data mining tool DTREG is evaluated on the basis model estimation criteria which are presented as follows:. It is a statistical drteg for qualitative categorical items re- garding inter-rater agreement or inter-annotator agreement [27].

The probability threshold report generated by the tool pro- vides information about how different probability thresholds would affect target category assignments. It is a frequently used measure of the differences between val- ues predicted by a model and the values actually observed. The network dtreeg shown above is a full-connected, three layered, feed forward, perceptron neural network.

Abstract — The objective of the paper is to compare two data mining tools on the basis of various estimation criteria. Multilayer perceptron model is implemented with the help of two different tools and subse- quently the performance of the tools is compared.

The basic idea of lift and gain is to sort the predicted target values in decreasing order of purity on some target cat- egory and then compare the proportion of cases with the cate- gory in each bin with the overall proportion. Usually the category with the highest probability is selected as the predicted category. The age-adjusted rates of oral tumor differ from over 20 for everypopulation in India, to 10 for everyin the U.

The results of these methods may possibly offer clinical medicine structure and build the model for medical issues that can provide extraordinarily benefit to healthcare industry In this paper, we attempt to apply data mining to oral can- cer database as it was estimated to be 8th most common can- cer worldwide inwith approximatenew cases anddeaths.

It takes the total absolute error and normalizes it by dividing by the total absolute error of the simple predictor. Mi- lovic et al. Confusion Matrix for both training and validation data is shown in Table [5].

Professional consultation is thus often delayed, increasing the chance for local spread and regional metastases. The variation in incidence and pattern of oral cancer is due to regional differences in the prevalence of risk factors. Hidden layer and Output layer activation function used in dgreg model is Logistic.
