## What is cost sensitive SVM?

This modification of SVM that weighs the margin proportional to the class importance is often referred to as weighted SVM, or cost-sensitive SVM.

**Are neural networks computationally expensive?**

Computationally Expensive. Usually, neural networks are also more computationally expensive than traditional algorithms. State of the art deep learning algorithms, which realize successful training of really deep neural networks, can take several weeks to train completely from scratch.

### What is the difference between SVM and SVR?

Those who are in Machine Learning or Data Science are quite familiar with the term SVM or Support Vector Machine. But SVR is a bit different from SVM. As the name suggest the SVR is an regression algorithm , so we can use SVR for working with continuous Values instead of Classification which is SVM.

**Is SVM faster than neural networks?**

We know that neural networks require significantly more time to train over a given dataset, with comparison to SVMs. Since, in this case, time is of the essence, our best bet is to use a support vector machine.

#### What is cost sensitive classification?

Cost-Sensitive Learning is a type of learning that takes the misclassification costs (and possibly other types of cost) into consideration. The goal of this type of learning is to minimize the total cost.

**Which neural network model is computationally expensive?**

Training deep neural networks

Training deep neural networks can be very computationally expensive. Very deep networks trained on millions of examples may take days, weeks, and sometimes months to train.

## What is cost in neural network?

The cost function of a neural network will be the sum of errors in each layer. This is done by finding the error at each layer first and then summing the individual error to get the total error.

**What are some of the advantages of using Support Vector Machine?**

Advantages of support vector machine :

- Support vector machine works comparably well when there is an understandable margin of dissociation between classes.
- It is more productive in high dimensional spaces.
- It is effective in instances where the number of dimensions is larger than the number of specimens.

### Is SVM still popular?

Popularity of these methods It is true that SVMs are not so popular as they used to be: this can be checked by googling for research papers or implementations for SVMs vs Random Forests or Deep Learning methods. Still, they are useful in some practical settings, specially in the linear case.

**What is cost-sensitive in machine learning?**

Cost-Sensitive Learning is a type of learning that takes the misclassification costs (and possibly other types of cost) into consideration. The goal of this type of learning is to minimize the total cost. — Cost-Sensitive Learning, Encyclopedia of Machine Learning, 2010.

#### Is logistic regression sensitive to imbalanced data?

Logistic regression does not support imbalanced classification directly. Instead, the training algorithm used to fit the logistic regression model must be modified to take the skewed distribution into account.

**What is the disadvantage of neural network?**

Disadvantages include its “black box” nature, greater computational burden, proneness to overfitting, and the empirical nature of model development. An overview of the features of neural networks and logistic regression is presented, and the advantages and disadvantages of using this modeling technique are discussed.

## What is the biggest problem with neural networks?

The very most disadvantage of a neural network is its black box nature. Because it has the ability to approximate any function, study its structure but don’t give any insights on the structure of the function being approximated.
