Introduction
Let us start this with a simple exercise, the kind of which every data scientist faces regularly:
You have been appointed as a store manager for our worst performing store. What are the possible factors / changes you would make in your store?
Take a few minutes to think over this. Once you have written at least a few factors, let’s move ahead.
So, how was the exercise? Was it easy or difficult? How sure are you that you have written all possible factors as part of this thought capture?
If you are not sure that you have captured most of the factors or your list looks like a simple to do list without any framework or structure, this article should help you tremendously.
The art of Structured thinking
Everyone has the ability to think simultaneously in all directions. But, the ability to think and ideate in a structured manner is what makes a data scientist special.
Structured thinking is a process of putting a framework to an unstructured problem. Having a structure not only helps an analyst understand the problem at a macro level, it also helps by identifying areas which require deeper understanding. Structured Thinking allows us to map our ideas in structured fashion, thereby enabling us to identify which areas need the most attention.
Sadly, people don’t realize the importance of structured thinking or go back to their unstructured instincts as soon as they face an unstructured problem. When I give the problem mentioned above to people, more than 70% of them don’t put a structure to it.
In this article, I’ve listed down some amazing mind mapping tools useful for a data scientists. These tools provide an excellent way of generating ideas in a creative way. These tools will enhance your breadth of thinking and your ability to comprehend and retain more information. Once you have gone through this article, you can bring these tools in your work flow process.
Note: Majority of the tools listed below can be availed for FREE. Links for access / download are provided. This article is not meant to promote any tool commercially.
What are Mind Mapping Tools ?
I too had this question when I first heard about these tools.
So, the existence of these tools derive from the concept of ‘mind-mapping’. Mind Mapping isn’t a new concept. It’s been used for centuries now. Basically, it’s a form of creative thinking.
Mind mapping is a process of creating mind maps used to convey ideas and concepts in a visual form. Mind maps are nothing but a visual representation of your thinking in a ‘structured manner’. Sometimes, you might find yourself in a situation where you find it immensely difficult to convince people with your idea. Be it your manger, boss or an investor. Has it happened with you?
Such situations occur when you idea fails to establish a visual impact in the mind of people at other end. That’s where mind mapping tools comes to your rescue. These tools use different colors, tree structures, pictures, animations to ensure that an idea is presented in the most comprehensible form.
What’s in it for a data scientist ?
Good question!
Among all the analysts, the idea of using mind mapping tool would appeal the most to people who are an ardent user of tree based algorithms such as decision trees, random forest, boosting etc.
Actually, mind maps follows a tree based structured, visual representation of ideas. When I first created one, I felt like as if I am creating tree nodes and terminal leaves of my ideas.
These tools can help you in following ways:
- It will allow you to implement structured thinking in your day to day tasks.
- It will be easier for you to explain your ideas, strategies to the clients, managers or your boss.
- You can move away from the cliche powerpoint presentations and use this creative form of information.
- Since our brain processes images / pictures faster than text, your mind maps would be much faster to comprehend by people.
- The tree and stem structure would help you analyze and gain insight on complex subjects quickly.
- You can redesign, modify the entire chain of ideas in one go.
- Prolonged use of this tool can certainly enhance your problem solving and memorization power.
In short, a data scientist will be accomplish more in less time using this creatively fast approach.
How to create a Mind Map ? – Practice Time!
Creating mindmaps is easy. You can draw it even using a pen and paper. The general methodology is as follows: Write the main idea in the center. Draw branches from the center such they are connected with one another with final outputs shown towards the end.
Let’s create a mind map based on a data science problem.
I’ve taken the problem from Big Mart Sales Prediction III. The task is to predict the sales of products.
We’ll create a mind map for hypothesis generation. Hypothesis generation helps us to understand the problem in detail by brainstorming possible factors which can impact the outcome. It is done by understanding the problem statement thoroughly and before looking at the data.
You can read the problem statement after login at the competition page. Below is a simple mind map I’ve created representing the possible factors which can affect product sales. I’ve used coggle tool (listed below).
Let’s understand it.
So, I’ve thought of possible factors on four levels: Store Level, Product Level, Customer Level and Macro Level. Let me quickly explain each factor:
Store Level Hypotheses :
- City type: Stores located in urban or Tier 1 cities should have higher sales because of the higher income levels of people there.
- Population Density: Stores located in densely populated areas should have higher sales because of more demand.
- Store Capacity: Stores which are very big in size should have higher sales as they act like one-stop-shops and people would prefer getting everything from one place
- Competitors: Stores having similar establishments nearby should have less sales because of more competition.
- Marketing: Stores which have a good marketing division should have higher sales as it will be able to attract customers through the right offers and advertising.
- Location: Stores located within popular marketplaces should have higher sales because of better access to customers.
- Ambiance: Stores which are well-maintained and managed by polite and humble people are expected to have higher footfall and thus higher sales.
Product Level Hypotheses:
- Brand: Branded products should have higher sales because of higher trust in the customer.
- Packaging: Products with good packaging can attract customers and sell more.
- Utility: Daily use products should have a higher tendency to sell as compared to the specific use products.
- Display Area: Products which are given bigger shelves in the store are likely to catch attention first and sell more.
- Visibility in Store: The location of product in a store will impact sales. Ones which are right at entrance will catch the eye of customer first rather than the ones in back.
- Advertising: Better advertising of products in the store will should higher sales in most cases.
- Promotional Offers: Products accompanied with attractive offers and discounts will sell more.
Customer Level Hypotheses
- Customer Behavior: Stores keeping the right set of products to meet the local needs of customers will have higher sales.
- Job Profile: Customer working at executive levels would have higher chances of purchasing high amount products as compared to customers working at entry or mid senior level.
- Family Size: More the number of family members, more amount will be spent by a customer to buy products
- Annual Income: Higher the annual income of a customer, customer is more likely to buy high cost products.
- Past Purchase History: Availablity of this information can help us to determine the frequency of a product being purchased by a user.
Macro Level Hypotheses
- Environment: If the environment is declared safe by government, customer would be more likely to purchase products without worrying if it’s environment friendly or not.
- Economic Growth: If the current economy shows a consistent growth, per capita income will rise, therefore buying power of customers will increase.
Mind you, this is not an exhaustive list. These are just some basic 21 hypothesis I have made, but you can think further and create some of your own. After this step, I’ll download the data and proceed with data analysis and predictive modeling stages.
I’m sure, after this activity you would have understood that the importance of a mind map lies in representing one’s thoughts in a better manner (as shown above).
Homework: Create a mind map of hypothesis on Loan Prediction Problem III. Share your mind maps on our twitter or facebook page. Best entry will receive a special gift hamper from AV.
