The progress can only be measured with clearly defined milestones. The input is the effort spent from the beginning of the project till the completion of a milestone. The productivity is the ratio of the earned value divided by the milestone cost. The calculation shows the shifts in ...
The chapter also reviews the diagnostic accuracy of classification measured by ROC-curves, and presents application examples based on statistical classification methods.

The proportion of accurately anticipated positive events out of all actual positive instances is measured by a recall. It is beneficial when the objective is to reduce false negatives. The ratio of true positives to the sum of true positives and false negatives is used to determine recall. F1 ...
Probability is measured as a value between 0.0 and 1.0, such that the total probability for all possible classes is 1.0. So for example, if the probability of a patient having diabetes is 0.7, then there's a corresponding probability of 0.3 that the patient isn't diabetic....
Speed (in the single node setting) is determined by computational complexity but also if the algo/implementation can use multiple processor cores. Accuracy is measured by AUC. The interpretability of models is not of concern in this project. In summary, we are focusing on which algos/...
This technique is applicable to small datasets and therefore requires fewer computational resources while increasing the classification accuracy as compared to CNNs models built from scratch. Transfer learning is a two-step process. An accurate data representation is first learned by training a model ...
The neural network presented in this chapter measured error using mean squared error. Some research evidence suggests an alternative measure, called cross entropy error, can generate more accurate neural network models. In my opinion, the research supporting the superiority of cross entropy error over...
However, the biomarker measurement is often limited by the sensitivity of the given assay, resulting in data that are censored at either the lower or the upper limit of detection. Inappropriate handling of censored data may affect the classification accuracy of biomarker and hinder the evaluation ...
of classifier’s solutions. Success of classification problem solutions is measured withclassification accuracy. It can also be used forrelational problemsunder the assumption that the relation membership is a two-class problem. Classification accuracy is defined as arelative frequencyof correct ...
uses the updating approach of weights. Faults are also propagated backward using this method. This method is constrained by local minima solutions. This study solves the problem by employing an effective modified technique that improves accuracy and is used in a variety of future prediction ...
