Data Science is the process of extracting valuable knowledge from large volumes of data. Data scientists work on automating analysis and creating models that provide useful insights automatically. They collect data, analyze it, and sometimes build decision-making systems, such as recommendation engines.
What is Big Data?
Big data refers to enormous datasets gathered from various sources, such as purchases, social media, or telecommunications. These data are analyzed to derive useful insights, such as consumer preferences or to optimize business processes.
Careers in Big Data:
→ Data Scientists create models for data analysis, build machine learning systems, and automate decision-making processes. They need a strong mathematical background and skills in working with neural networks.
→ Data Engineers handle data collection, processing, and storage to ensure its reliability and usability. They write scripts, work with databases, and manage APIs.
→ Data Analysts analyze data to answer specific business questions, create visual reports, and help make informed decisions. They often use visualization tools like Tableau.
Neural Networks and Machine Learning
Neural networks are an important tool for data scientists. They are trained to recognize patterns and make predictions based on large datasets.
Machine learning involves training neural networks to produce accurate results.
Key Skills to Start Working with Big Data:
- Mathematics (linear algebra, probability theory, statistics)
- Machine Learning (using TensorFlow, PyTorch)
- Programming (Python and R)
- Data Collection (working with APIs and data scraping)
- Data Visualization (presenting data in a comprehensible way)
