How can you increase the accuracy of multiclass classification?
How to improve accuracy of random forest multiclass classification model?
- Tuning the hyperparameters ( I am using tuned hyperparameters after doing GridSearchCV)
- Normalizing the dataset and then running my models.
- Tried different classification methods : OneVsRestClassifier, RandomForestClassification, SVM, KNN and LDA.
When do you have a multi class classification problem?
Multi-class classification is when you have a classification problem with multiple classes, specifically 3 or more classes. Many classifications are binary by design, therefore the additional nomenclature of multi-class classification was defined to describe algorithms capable of classifying datasets with more than 2 classes.
How is multiclass classification used in machine learning?
Many classifications are binary by design, therefore the additional nomenclature of multi-class classification was defined to describe algorithms capable of classifying datasets with more than 2 classes. Learn more… How to apply Helmert Coding in a real Machine Learning model?
How does multiclass classification with imbalanced dataset work?
Multi-class classification makes the assumption that each sample is assigned to one and only one label: a fruit can be either an apple or a pear but not both at the same time. Imbalanced Dataset: Imbalanced data typically refers to a problem with classification problems where the classes are not represented equally.
How to model multi class classification using neural networks?
When modeling multi-class classification problems using neural networks, it is good practice to reshape the output attribute from a vector that contains values for each class value to be a matrix with a boolean for each class value and whether or not a given instance has that class value or not.
