Rare Data Science Skills You Need to Become a Data ScientistÂ
The following are the rare skills you need to have to become a data scientist:
Model VisualizationÂ
Data scientists used to work alone without any dependencies on others. They used to create the models showing up the predictions on the historic dataset using Data science skills. These used to be passed to the C-level executives in the company to understand the predictions and make appropriate business decisions.Â
Now, companies want to understand the data science outputs in detail. It is a must for data scientists to explain what the model does, how it works and why they choose that target column to make predictions.Â
You can work with the visualization team to show the predictions visually in the form of a bar or pie chart with Data science skills. For instance, you have come up with a model that can predict the churn of telecom companies. Instead of showing the code to them, it is good to show the bar charts that explain the model and the predictions.Â
You can segment the customers and find out the areas where they have a high chance of increasing the number of customers. The model is transparent and easier for even non-technical savvy to understand. It is one of the great Data Science Skills to explain the model through the code you have written, but you need to use flowchart tools to explain the decision tree while explaining the code to a non-data scientist or a non-coder.Â

Feature Engineering
It is the most important Data Science Skills and tool the aspiring data scientist should have. You can learn a bit about this in the data science course. However, you need to identify the features that can have an impact on creating a precise model.Â
In addition, you can use this model to make predictions accurately. The data scientists give high priority to model algorithms. They use the best algorithms to create models using historical data.Â
Priority should be given to features in the data. When you identify the correlated features to the target feature, you can make a powerful model. With feature engineering, you can select, modify, and create features that boost the performance of ML models.Â
For instance, when you are developing a model to predict real-estate prices in different locations, it is necessary to take features like bedrooms, square feet, and location into consideration. These all factors decide the pricing. Using feature engineering, these features are considered for price prediction. You must calculate the closest transportation station or come up with a feature that can show the property’s age. You can combine these features with new ones. The new features you must consider are crime rate, ratings of schools and amenities around.Â
It is one of the rare Data science skills that every data scientist should have to become successful in this area of job. They are technically sound, but they also need to have domain knowledge. This helps them predict better, creating effective ML models.Â
You have to have the right data in hand and transform this data into an informative piece. Using this informative piece, you can test and train the models. The machine learning courses impart extensive knowledge of feature engineering to students. Learning this one of the most in-demand data science skills will be an add-on for every student.Â
They can excel in this area and can build models that give accurate predictions on any data. You also have to work on the real-time data to use your feature engineering strategies. This helps you strengthen your skills.Â
Learn About Data GovernanceÂ
Data governance is a must for data scientists. When you are provided with the patient data and asked to come up with a model that can predict the patients who are at risk of some diseases. Then the biggest challenge that every data scientist faces is developing effective models. However, not just this the model should also be ethical and sustainable.Â
You have to make sure that the data you gathered for modeling is compliant with HIPAA and GDPR rules. However, you have to meet this compliance in case you are taking the data from the locations where these rules are stringent. You need to know whether you have the authority to use this data legally. In case you have that authority, you must keep this anonymous. It is a must for you to take consent from patients.
Apart from these Data Science Skills, you should also do the documentation of the code, data transformations you have used and models you have generated. This helps even a non-expert user to understand what you have done on that dataset. You must have traceability to stay compliant for future audits too.Â
Ethics
If you are a data scientist, you must be familiar with data scientist skills and responsibilities. Apart from knowing how to create models, you should also be ethical. The models you create from the data should not evoke biases among other groups. Your models should treat all segments in the dataset equally. There is a big company which has come up with the recruitment model.Â
Using this model, the HR team can pick the potential candidates from a group of resumes and start to conduct interviews for them. The models are trained on the resumes of candidates. All these are male-dominated. The model they have developed is favoring male hires.Â
All the resumes it picked are males instead of data science skills and tools. Therefore, this model is completely unethical.
The data scientist is a good decision-maker. The decisions a data scientist makes will have a huge impact on people. You cannot be ignorant. Whenever you are creating a model from the dataset with Data science skills, you must perform data transformations and segmentations properly.Â
Without which a lot of repercussions arise. You have to think a lot about which transforms to apply and which data to pick. This helps you bring up a model that is useful for all.

Marketing
You should know how to market your skills. The better you market your achievements, projects and skills, the faster you get the job. When your data science skills resume looks rich, companies will shortlist you for interviews. They will consider allowing you to prove it.Â
This is all possible only when you have good marketing skills. If you sell your resume, you can attract the interviewer and grab a high-paying job. In data science, you should be able to explain what models you have built and be able to explain those clearly. No matter how good the model is, if you do not have good convincing and marketing skills all efforts go into vain. For instance, if you have come up with a model that can predict equipment failure. This model helps you to do frequent maintenance to avoid equipment failure in manufacturing plants.Â
Using this model, you can save a lot of money in avoiding the equipment to have increased downtime. In case you cannot explain this to the C-level executives, the model you developed won’t be of any use.Â
Having good soft skills for data scientist lets people explain the model clearly. You must be good at convincing and impressing the interviewers.Â
Having skills required for data scientist fresher also helps you to let people know how useful the model you developed is. You can prepare a presentation and highlight how your model can save a huge amount of the company’s money.Â
The model you develop should also improve productivity and should give long-term benefits. All these should be explained in the presentation without missing any point. If you can’t sell your achievements no one can better do it for you.Â
It is one among the rare Data science skills that is not taught anywhere but should be inculcated by yourself. Many data scientists lack this. In case you have this, you can make a difference in the company and in winning the interview.Â
The data scientists just work towards building an accurate model and fail to explain how it works. The real advantage of the market can be taken only when you market yourself. There are courses available to learn marketing yourself.Â
