# Difference Between Generative And Discriminative Classifiers

There are a few types of classical supervised machine learning algorithms: Naive Bayes, MaxEnt (also called Logistic Regression), Decision TreesHidden Markov Models (HMMs), Support Vector MachinesConditional Random Fields (CRFs), Neural Networks, and some others. The top n list may differ depending on the field they are used in.

Most of those types have a few sub-types based on the kinds of tasks they are designed for and implementation approaches they leverage, for example, Bernoulli Naive Bayes, linear-chain CRFs, etc.

Models built using four of those main algorithms — Naive Bayes, MaxEnt, HMMs, and CRFs — can be split into two groupings, generative and discriminative (also called conditional). Let’s see how they differ and how they correspond to each other.

1. Naive Bayes

Naive Bayes is one of the most basic algorithms. It produces a generative model and this model captures the joint probability p(y, x) — so having y, you can generate a random vector of x.

It makes a couple of simplifying assumptions, hence it’s “naive”. The most important one is that all input variables are conditionally independent of one another. It also assumes that the position of the variable doesn’t matter.

So, based on Bayes’ theorem, we’ll model posterior as follows:

Naive Bayes

p(x) — the probability of the feature vector across the dataset — is going to be the same for either class. So for practical reasons, we can drop it and assume that:

Naive Bayes

In any case, p(x) is extremely difficult to model, especially for named entity recognition (NER) tasks with proper names, because x will most probably never occur in the training set.

At the same time, p(y, x) = p(y) p(x|y), thus it models the joint probability.

Using the chain rule, the previous formula can be re-written as:

Naive Bayes

Naive Bayes is easy to implement and is known to perform well for certain tasks, including text classification, and may be preferred under certain conditions, for instance when the training data is scarce. However, it’s not very robust. One of the issues is, for example, “double counting” — such a model doesn’t take into account how often certain words co-occur together in the same class, for example, ‘CEO’ and ‘sales’ in ‘Business’.

User-generated content has superseded other marketing trends and fallen into the advertising feeds of brands. Today, more than 86 percent of companies use user-generated content as part of their marketing strategy.

In the year 2020, there are 3.81 million people actively using social media around the globe. That is the reason social media content matters. Whenever users look at the content on social media that is posted by an individual, then they may be influenced by their content. Perhaps, it can be used to gain more customers or followers on your social media platforms.

In addition to this, the plugin also provides more than 40 customization options to make your social stream feeds more attractive.

The customer survey provides powerful insights you need to make a better decision for your business. Moreover, it is great user-generated content that is useful for identifying unhappy consumers and those who like your product or service.

In general, surveys can be used to figure out attitudes, reactions, to evaluate customer satisfaction, estimate their opinions about different problems.

Within a few minutes, you can design and load a customer feedback survey and send it to your customers for their response. From the customer survey data, you can find your strengths, weaknesses, and get the right way to improve them to gain more customers.

1. Run Contests
A contest is a wonderful way to increase awareness about a product or service. Contest not just helps you to enhance the volume of user-generated content submissions, but they also help increase their quality. However, when you create a contest, it is important to keep things as simple as possible.

Furthermore, running contests also improve the customer-brand relationship and allows more people to participate in it. It will drive a real result for your online business. If your WordPress website has Google Analytics, then track contest page visits, referral traffic, other website traffic, and many more.

1. Review And Testimonials
Customer reviews are a popular user-generated content strategy. One research found that around 68% of customers must see at least four reviews before trusting a brand. And, approximately 40 percent of consumers will stop using a business after they read negative reviews.

Reviews are powerful as the platform they are built upon. That is the reason it is important to gather reviews from third-party review websites like Google review, Facebook review, and many more, or direct reviews on a website. It is the most vital form of feedback that can help brands grow globally and motivate audience interactions.

However, you can also invite your customers to share their unique or successful testimonials. It is a great way to display your products while inspiring others to purchase from your website.

1. Video Content
A great video is a video that is enjoyed by visitors. These different types of videos, such as 360-degree product videos, product demo videos, animated videos, and corporate videos. The Facebook study has demonstrated that users spend 3x more time watching live videos than normal videos. With the live video, you can get more user-created content.

Moreover, Instagram videos create around 3x more comments rather than Instagram photo posts. Instagram videos generally include short videos posted by real customers on Instagram with the tag of a particular brand. Brands can repost the stories as user-generated content to engage more audiences and create valid promotions on social media.

Similarly, imagine you are browsing a YouTube channel, and you look at a brand being supported by some authentic customers through a small video. So, it will catch your attention. With the videos, they can tell you about the branded products, especially the unboxing videos displaying all the inside products and how well it works for them. That type of video is enough to create a sense of desire in the consumers.
