Overview
This project utilizes advanced machine learning techniques to optimize the data science curriculum, ensuring it aligns with current industry demands. The primary goal is to update and enhance course offerings to prepare aspiring data scientists with relevant and practical skills. By analyzing over 1,000 job postings from the United States, this project identifies the most in-demand skills in the data science field and integrates them into an educational framework.
Objectives
- Align Curriculum with Market Demands: Ensure the educational content is relevant and practical for data science professionals.
- Identify Essential Skills: Categorize technical and soft skills essential for data scientists, derived from real job postings.
- Optimize Learning Modules: Utilize machine learning to segment the data science skills into clearly defined clusters, forming the basis of the curriculum modules.
Methodology
- Data Collection and Cleaning
The dataset includes over 1,000 job postings focused on roles like Data Scientists and Data Engineers. Techniques like web scraping were used to gather and clean the data, ensuring a high-quality dataset for analysis.
