How is Naive Bayes a Linear Classifier? - Cross Validated
Mar 18, 2015 · As we can see, the decision boundary is non-linear. Is it trying to say that the parameters (conditional probabilities) are a linear combination in the log space rather than …
classification - Why is logistic regression a linear classifier ...
Transforming "a linear combination of the input into a non-linear output" is a basic part of the definition of a Linear Classifier. That reduces this question to the second part, which amounts …
Why KNN is a non linear classifier - Cross Validated
A classifier is linear if its decision boundary on the feature space is a linear function: positive and negative examples are separated by an hyperplane. This is what a SVM does by definition …
What is the relation between Linear Classifier and Linear Decission ...
Jul 6, 2021 · I have seen so many examples , like for SVM classifier, we transform the data to higher dimension and get the hyperplane in feature space but in input space it has non linear …
Linear regression for multi-class classification - Cross Validated
Oct 7, 2019 · Linear regression can be used for binary classification where it competes with logistic regression. While the fitted values from linear regression are not restricted to lie …
How does a simple logistic regression model achieve a 92% ...
Sep 11, 2019 · It seems baffling to me how multi-class logistic regression produces such a high accuracy with entirely linear features (no polynomial features). As an example, given any pixel …
Why not approach classification through regression?
Although many would argue that linear regression is not right for classification, it may still work. To gain some intuition, I included linear regression (used as classifier) into scikit-learn's classifier …
Overfitting with Linear Classifiers - Cross Validated
Oct 6, 2015 · Today our professor stated in class that "overfitting with linear classifiers is not possible". I hold that to be wrong, since even linear classifiers can be sensitive to outliers in …
