Machine learning classifiers often stumble over imbalanced datasets where classes are not equally represented. This inherent bias towards the majority class may result in low accuracy in labeling minority class. Imbalanced learning is prevalent in many real-world applications, such as medical research, network intrusio…

7 results for “ADASYN”
This paper tackles imbalanced data in binary classification problems.
problem Imbalanced data leads to skewed results in classification problems.
method Synthetic Minority Oversampling Technique (SMOTE) and Adaptive Synthetic (ADASYN) Sampling Approach.
result Synthetic data points enhance understanding of oversampling techniques.
In this paper we propose the use of Generative Adversarial Networks (GAN) to generate artificial training data for machine learning tasks. The generation of artificial training data can be extremely useful in situations such as imbalanced data sets, performing a role similar to SMOTE or ADASYN. It is also useful when t…
The study reduces a personality measurement instrument to 10 features with minimal loss of accuracy.
problem Accurately predicting personality types with minimal predictors.
method Reduced a 94-item personality survey to 10 features, using class imbalance correction methods.
result Achieved 73.81% accuracy on unseen data with only 1% loss.
Cardiovascular diseases are one of the most common causes of death in the world. Prevention, knowledge of previous cases in the family, and early detection is the best strategy to reduce this fact. Different machine learning approaches to automatic diagnostic are being proposed to this task. As in most health problems,…
