Epic and Theme

Epic and Theme


What is an Epic?

An epic is a large story, an epic is usually a story that cannot be completed within one iteration or within one sprint in the scrum. An epic needs to be broken down into separate stories before working on it.

So what makes this an epic?

Well, the things that usually make a story into an epic are firstly we're early in a project and we don't have all of the information that we will end up having around this particular user story.


What is a Theme?

A theme is a collection of stories with a shared attribute. Here's an example of a theme.

SPORTS PAGE: As a sports fan I want a group of sports pages so that I can see the top 10 news stories for each sport.

The difference between an epic and a theme is that whereas an epic is simply a large story that may be broken down into further stories later, a theme actually refers to a collection of stories.

Here, in this case, we know that we're going to need many sports pages and the product owner is going to want a way to refer to all of the stories that are associated with this theme.

SPORTS PAGE: As a soccer fan I want a football fan page so that I can see the top 10 football news stories. 

And the second 

SPORTS PAGE: As a baseball fan I want a baseball home page so that I can see the top 10 baseball news stories.

How to split User stories

  • Don't meet performance constraints
    • The user should be able to load the page in less than 30 milliseconds.

  • Remove cross-cutting concerns
    • Logging
    • Common Messages
    • Security

  • Number three, separate by mixed priority
    • The user should see an advertisement for the sports channel below each new story measuring five by two inches.

Maxpooling vs minpooling vs average pooling

Image
Pooling is performed in neural networks to reduce variance and computation complexity. Many times, beginners blindly use a pooling method without knowing the reason for using it. Here is a comparison of three basic pooling methods that are widely used. The three types of pooling operations are: Max pooling: The maximum pixel value of the batch is selected. Min pooling: The minimum pixel value of the batch is selected. Average pooling: The average value of all the pixels in the batch is selected. The batch here means a group of pixels of size equal to the filter size which is decided based on the size of the image. In the following example, a filter of 9x9 is chosen. The output of the pooling method varies with the varying value of the filter size. The operations are illustrated through the following figures. Average, Max and Min pooling of size 9x9 applied on an image We cannot say that a particular pooling method is better over others generally. The choice of pooling operation is made...

Percentiles, Deciles, and Quartiles

Image
Percentiles Percentile: the value below which a percentage of data falls. Example: You are the fourth tallest person in a group of 20 80% of people are shorter than you: That means you are at the  80th percentile . If your height is 1.85m then "1.85m" is the 80th percentile height in that group. In Order Have the data  in order , so you know which values are above and below. To calculate percentiles of height: have the data in height order (sorted by height). To calculate percentiles of age: have the data in age order. And so on. Grouped Data When the data is grouped: Add up all percentages  below  the score, plus  half  the percentage  at  the score. Example: You Score a B! In the test 12% got D, 50% got C, 30% got B and 8% got A You got a B, so add up all the 12% that got D, all the 50% that got C, half of the 30% that got B, for a total percentile of 12% + 50% + 15% =  77% In other words you...

Data Warehouse Vs Data Mart

Image
What is Data Warehouse? A Data Warehouse collects and manages data from varied sources to provide meaningful business insights. It is a collection of data that is separate from the operational systems and supports the decision making of the company. In Data Warehouse, data is stored from a historical perspective. The data in the warehouse is extracted from multiple functional units. It is checked, cleansed and then integrated with the Data warehouse system. Data warehouse used a very fast computer system having large storage capacity. This tool can answer any complex queries relating to data. What is Data Mart? A data mart is a simple form of a Data Warehouse. It is focused on a single subject. Data Mart draws data from only a few sources. These sources may be central Data warehouse, internal operational systems, or external data sources. A Data Mart is an index and extraction system. It is an important subset of a data warehouse. It is subject-oriented, and it is desig...
