Introduction to Data Science

Data Science is an interdisciplinary topic that combines Statistics, Computer Science, and Machine Learning techniques to extract insights from Structured and Unstructured Data. Data Science is one of the decade’s fastest-growing, most complex, and well-paying careers. Upon understanding its importance, numerous Data Science Companies have emerged to provide Data-Driven solutions across industries.

Key Components of Data Science

A majority of the top Data Science Companies follow a similar pattern to proceed in a Data Science Project. The key components in any Data Science Project are: 

  • Step 1: Data Exploration 
  • Step 2: Data Modelling 
  • Step 3: Testing the Model 
  • Step 4: Deploying Models

Step 1: Data Exploration 

Data Exploration is the most crucial phase as it takes the most time for all the Data Science Companies. Data Exploration takes up around 70% of the complete project duration. Since Data is the most important component of Data Science, Data is rarely available in a well-formatted way. The Data often contains a significant amount of noise. The term “noise” refers to a large amount of unnecessary Data. 

This process entails Data Sampling and Transformation, during which evaluation of Observations (Rows) and Features (Columns) are done and Statistical methods are used to reduce noise. This stage is also used to evaluate the relationship between Distinct Features in the Dataset; “relationship” means whether the Features are dependent or independent of one another, and whether or not there are missing values in Data. All the Data Science Companies spend most of their time in Data Exploration.

Step 2: Data Modelling

So far, the Data has been prepared and is ready to go. This is the second step taken by Data Science Companies, in which Machine Learning Algorithms come into the picture. This is where the Data is fitted into the model. The Model is chosen based on the type of Data selected and the business requirement to be fulfilled. For example, the model chosen for proposing an article to a consumer will be different from the model necessary for estimating the number of articles sold on a given day. 

Step 3: Testing the Model

This is the following step, and it is critical to the model’s success. The model is tested with Test Data to ensure that it is accurate and has other desirable properties, and necessary changes are made to the model to achieve the intended result. If we do not achieve the requisite precision, we can return to Step 2 (Data Modelling), choose an alternative model, and then repeat Step 3 and then select the model that produces the best results for the business. This is a very important step for Data Science Companies as the accuracy of the model is found at this stage.

Step 4: Deploying Models

The model which provides the best result based on test findings is completed and deployed in the production environment whenever the desired result is achieved through proper testing as per the business needs.

Key Skills Required in Data Science

Data Science Companies - key skills

All Data Science Companies expect the ideal candidate to know some skills. Below, are the skills one should know before applying to any Data Science Organization:

  • Statistics and Probability
  • Programming Skills
  • Data Visualization Skills
  • Machine Learning and Deep Learning
  • Communication Skills

1) Statistics and Probability 

Data Science is built on the foundations of Statistics and Probability. Probability Theory is quite useful in formulating predictions. Data Science relies heavily on Estimations and Projections. We make Estimations for further examination with the use of Statistical approaches. As a result, Statistical approaches are heavily reliant on Probability Theory. Statistics and Probability are solely based on Data.

2) Programming Skills

Python is the most prevalent coding language required in the Data Science profession, however other programming languages such as R, Perl, C/C++, SQL, and Java are also used. Data Scientists can use these programming languages to arrange Unstructured Data Collections.

3) Data Visualization Skills

People skim and skip the most essential stories in the newspaper, but the ones that people read are mostly Sketches. It is a human concept to see something and have it registered in one’s mind. The complete Dataset, which may number in the hundreds of pages, can be reduced to two or three Graphs or Plots. To create Graphs, one must first visualize the Data Patterns. Microsoft Excel is a fantastic program that generates the appropriate Charts and Graphs based on our requirements. Tableau, Metabase, and Power BI are some examples of other Data Visualisation and Business Intelligence tools.

4) Machine Learning and Deep Learning 

Machine Learning is a must-have ability for any Data Scientist. Predictive Models are created using Machine Learning. For example, if you want to forecast how many clients you’ll have in the upcoming month based on the previous month’s Data, you’ll need to employ Machine Learning techniques. The Data Science Companies are always trying to improve the accuracy of Machine Learning and Deep Learning Models they build. 

5) Communication Skills

You must communicate your findings to a group of Teammates or Senior Management. Communication allows us to rise above what everyone is fighting for. Being a competent communicator allows you to convey ideas and identify any Data Contradictions. In a Project, in Data Science Companies presentation skills are crucial for showcasing Data Discoveries and planning the future.

Understanding the Need for Data Science

All Data Science Companies understand the need for Data Science and try to provide their services across all industries. Below are the two main needs which non-Data-driven companies should look upon:

  • Historical Data: With Data Science housing strong tools, it assists us in extracting insights from past Data. It aids in the optimization of the business, hiring the right people, and the generation of more money, as Data Science enables you to make better business decisions in the future.
  • Business Strategy: Data Science Companies can better create and advertise their products by narrowing down their target market. Consumers can use Data Science to find better products, especially on E-Commerce websites that use a Data-driven recommendation engine.
