Data Science applications

 If you are a certified data scientist, you probably have encountered some of these issues before. If you are a beginner, these use cases will help you learn different data science ideas that can be applied across the industry. Data science challenges are not evolving as quickly as possible for most organizations. Use cases will grow through many competitors depending on your planning needs and expectations. It is crucial to provide insights into current use cases so that they can be condensed and applied to new use cases. You'll occasionally encounter scenarios that haven't been written about in articles or studied at institutions. The allure of data science is that it is scalable and applicable to many issues while requiring relatively little effort.

 1. Credit Card Fraud Detection

We'd create a supervised model to classify it as either fraud or not fraud in this situation. In an ideal world, you'd have many samples of what noise looks like in your data.

 2. Customer Segmentation

Unsupervised learning would be preferred over classification to employ clustering in this circumstance. K-Means is a traditional clustering algorithm. This task is unsupervised because you don't possess labels and don't know what to group. However, you'd like to uncover patterns of novel combinations based on their shared points.

 3. Customer Churn Prediction

A family of machine learning techniques could help with this problem. This query is similar to the one used to detect credit card fraud. We want to collect customer information with a specific label, such as churn or no-churn.

 4. Sales Forecasting

Forecasting transactions is perhaps the most diverse of the three use cases discussed so far. We can apply deep learning to anticipate future commodities purchases in this example. The LSTM algorithm was utilized. LSTM stands for Long Short-Term Memory.

Data Science vs. Business Analytics


Key Differences Between Data Science and Business Analysis:

Here are some of the key differences between data scientists and business analysts.

1. Data science is the science of studying data using statistics, algorithms and technologies, and business analysis is the statistical study of business data.

2. Data science is a relatively recent development in analytics, but business analytics has existed since the late 19th century.

3 Data science requires a lot of programming skills, but business analysis doesn't require a lot of programming.

4. Data science is an important subset of business analysis. Therefore, anyone with data science skills can do business analysis, but not vice versa.

5. Taking data science one step ahead of business analysis is a luxury. However, business analysis is needed for companies to understand how it works and gain insights.

6. Analytical Data Science results cannot be used for everyday business decision making, but business analysis is essential for critical administrative decision making.

7. Data science does not answer obvious questions. Questions are almost common. However, business analysis mainly answers very specific questions about finance and business.

8. Data science can answer questions that can be used for business analysis, but not the other way around.

9. Data science uses both structured and unstructured data, while business analytics primarily uses structured data.

10. Data science has the potential to make a big leap, especially with the advent of machine learning and artificial intelligence, while business analysis is still slow.

11. Unlike business analysts, data scientists don't come across a lot of dirty data.

12. In contrast to business analysis, data science relies heavily on data availability.

13. Investing in data science The cost of is high and business analysis is low.

14. Data science can keep up with today's data. Data is growing and diverging into many data types. Data scientists have the necessary skills to handle it. However, commercial analysts do not own it.


Data Science and Business Analytics Comparison Table

Below is the comparison table between Data Scientist and Business Analytics.

Comparison base

Data Science

Business Analytics

Coining of Term

In 2008, DJ Patil and Jeff Hammerbacher from LinkedIn and Facebook, respectively, invented the term Data Scientist.

Since Frederick Winslow Taylor's implementation in the late 1800s, business analytics has been in use.

Concept

Data inference, algorithm development, and data-driven systems are all interdisciplinary fields.

To derive insights from business data, statistical principles are used.

Statistics

Following the creation and coding of algorithms, statistics is used at the end of the analysis.

The entire investigation is based on statistical principles.
