Question-36: What do you mean by Topic Modeling?
Answer: This is also an example of un-supervised learning. Like you want to group all the research papers based on their respective area, which are not known in advance. You use Topic modeling, in which you find the related words in each individual document and then group them together. So that they can be segmented on devised group once they are processed by your Model.
Question-37: In Graph Analytics, what vertices and edges represent?
Answer: In graph analytics vertices represents the objects and edges represent relationships among the objects. For example, Objects can be human being in the social networking and edges represent relationships between two human beings. Once you take a look of properties for the vertices and edges, you can better understand the relationship between objects.
Question-38: Can you use graph analytics for fraud detection between transactions?
Answer: Yes, we can. Let’s assume we already have historical data like phone numbers, addresses, email ids etc. from historical fraud transactions. Now you want to catch any new fraud or suspicious transactions. You can build a model which can capture the transactions between two fraud phone numbers or contacts. Which can be possibly a fraud transaction on newer way.
Question-39: Can you give another example; how can you use say that a particular relationship is suspicious?
Answer: Lets assume you have a graph with the created with your data. And on average you found that each individual vertex has 8-10 edges. But there are 2 nodes/vertex in entire graph has only 1 edge. Then you can consider that relationship as a suspect.
Question-40: Can we use to determine the influencer in social graph using graph analytics?
Answer: Yes, it is possible. Let’s assume you have social graph created and you can classify individual as an influencer based on its edges count or other properties. And this can be used as a classifier to check an individual an influencer or not. If individual is an influencer then companies can use that influencer to advertise their brands.
