In a dataset with highly unbalanced classes, if the classifier always "predicts" the most common class without performing any analysis of the features, it will still have a high accuracy rate, obviously illusory. 解决办法 解决样本不平衡的问题,有两个大的方向是可以解决的。一个是under-sampling,另...
Applications of NNs for regression analysis and outcome prediction based on small datasets remain scarce and thus require further exploration [2], [9], [10]. For the purposes of this study, we define small data as a dataset with less than ten observations (samples) per predictor variable. ...
MedMNIST Classification Decathlon: A Lightweight AutoML Benchmark for Medical Image Analysis(ISBI'21) Key Features Diverse: It covers diverse data modalities, dataset scales (from 100 to 100,000), and tasks (binary/multi-class, multi-label, and ordinal regression). It is as diverse as the VDD...
The logistic regression and neuralnetwork methods with sensitivity analysis have been evaluated for the effectiveness of theclassification. The classification accuracy is used to measure the performance of both themodels. From the experimental results it is confirmed that the neural network model with...

The 95 threshold (95 percentile) is used to end the heatwave drastically if the temperature drops below this threshold. The chosen method was recently demonstrated to be the most effective in detecting and characterizing heat waves for building resilience analysis57. The current work builds on the...
CART uses Gini impurity (an information-theoretic measure corresponding to Tsallis entropy) as a metric, solving the problem that ID3 not handle the regression task. DT has an intuitive classification strategy, is interpretable and simple to implement, and often allows for better generalization ...
The GBD project also did a meta-analysis and regression of available epidemiological studies, resulting in 1000 splined meta-regression estimates for 385 integer exposure levels ranging from 0 μg/m3 to 2500 μg/m3.27 To convert these regression estimates to RR estimates for use in our health ...
