The prior SVMs worked with linearly separable data. If we would like to separate non-linear data, we can change how we project the linear separator onto the data. This is done by changing the kernel in the SVM loss function. In this article, we introduce how to change kernels and separate non-linear separable data.

We will motivate the usage of kernels in support vector machines. In the linear SVM section, we solved the soft margin with a specific loss function. A different approach to this method is to solve what is called the dual of the optimization problem. It can be shown that the dual for the linear SVM problem is given by the following formula:

Here, the variable in the model will be the b vector. Ideally, this vector will be quite sparse, only taking on values near 1 and -1 for the corresponding support vectors of our dataset. Our data point vectors are indicated by_ xi _and our targets ( 1 or -1 ) are represented by _yi _.

The kernel in the preceding equations is the dot product,_ xi.xj,_, which gives us the linear kernel. This kernel is a square matrix filled with the _i,j _dot products of the data points.

Instead of just doing the dot product between data points, we can expand them with more complicated functions into higher dimensions, in which the classes may be linearly separable. This may seem needlessly complicated, but if we select a function, k, that has the property where:

Xfinity, the tradename of Comcast Cable Communications, LLC, is the first rate supplier of Internet, satellite TV, phone, and remote administrations in the United States. Presented in 2010, previously these administrations were given under the Comcast brand umbrella. Xfinity makes a universe of mind boggling amusement and innovation benefits that joins a great many individuals to the encounters and minutes that issue them the most. Since Xfinity is the greatest supplier of link administrations and home Internet in the United States, it isn’t amazing that the organization gets a ton of investigating and inquiry goal demands on its telephone based Xfinity Customer Service.

Deep Learning is one of the most in demand skills on the market and TensorFlow is the most popular DL Framework. One of the best ways in my opinion to show that you are comfortable with DL fundaments is taking this TensorFlow Developer Certificate. I completed mine last week and now I am giving tips to those who want to validate your DL skills and I hope you love Memes!

**Do the DeepLearning.AI TensorFlow Developer Professional Certificate Course on Coursera Laurence Moroney and by Andrew Ng.**

**2. Do the course questions in parallel in PyCharm.**

In this tutorial, we will provide you an example of how you can build a powerful neural network model to classify images of **cats **and **dogs** using transfer learning by considering as base model a pre-trained model trained on ImageNet and then we will train additional new layers for our cats and dogs classification model.

We will work with a sample of 600 images from the Dogs vs Cats dataset, which was used for a 2013 Kaggle competition.
