## How is the generative model used in classification?

Generative model. In application to classification, one wishes to go from an observation x to a label y (or probability distribution on labels). One can compute this directly, without using a probability distribution ( distribution-free classifier ); one can estimate the probability of a label given an observation, ( discriminative model ),…

**Which is a class of generative adversarial networks?**

One class of such models is called generative adversarial networks which are pretty useful for generating new images and are pretty interesting too. Here is the kernel with all the code along with the visualizations.

**How are generative models used in machine learning?**

Generative model. In statistical classification, including machine learning, two main approaches are called the generative approach and the discriminative approach. These compute classifiers by different approaches, differing in the degree of statistical modelling.

### Which is better discriminative model or generative model?

Despite the fact that discriminative models do not need to model the distribution of the observed variables, they cannot generally express complex relationships between the observed and target variables. They don’t necessarily perform better than generative models at classification and regression tasks.

**How is a Gan different from a generative model?**

In contrast, the generative model tries to produce convincing 1’s and 0’s by generating digits that fall close to their real counterparts in the data space. It has to model the distribution throughout the data space. GANs offer an effective way to train such rich models to resemble a real distribution.

**How is generative modeling related to discriminative modeling?**

Discriminative modeling estimates p ( y | x ) —the probability of a label y given observation x. Generative modeling estimates p ( x ) —the probability of observing observation x. If the dataset is labeled, we can also build a generative model that estimates the distribution p ( x | y ) .

#### Can a generative model be used to generate new digits?

Using the dataset of handwritten digits, you could train a generative model to generate new digits. During the training phase, you’d use some algorithm to adjust the model’s parameters to minimize a loss function and learn the probability distribution of the training set.
