3. Deep Learning (DL)
Definition: Deep Learning is a subset of ML that uses neural networks to process complex data and make decisions like a human brain.
Examples of Deep Learning in Real Life:
- Image Recognition: Google Photos identifies people in pictures.
- Speech-to-Text: YouTube automatically generates subtitles.
- Autonomous Vehicles: Self-driving cars process video feeds in real-time.
Ongoing Projects in Deep Learning:
- OpenAI Codex: AI that writes code.
- Google Brain: AI for natural language understanding.
- Meta AI: Improving deepfake detection.
4. Data Science
Definition: Data Science involves extracting insights from large amounts of data using statistics, ML, and data visualization.
Examples of Data Science in Real Life:
- Healthcare Analytics: Predicting disease outbreaks.
- E-commerce: Understanding customer behavior to improve sales.
- Finance: Risk assessment in loans.
Ongoing Projects in Data Science:
- IBM Watson Analytics: AI-driven data analysis.
- Google’s BigQuery: Handling massive datasets.
- NASA Earth Data Analysis: Climate pattern studies.
5. Big Data
Definition: Big Data refers to extremely large datasets that traditional databases can’t handle efficiently.
Examples of Big Data in Real Life:
- Social Media Data: Facebook processes petabytes of data daily.
- Stock Market Analysis: Predicting trends using past data.
- Weather Forecasting: Analyzing climate patterns.
Ongoing Projects in Big Data:
- Hadoop & Apache Spark: Open-source big data frameworks.
- Google Cloud Bigtable: Managing structured data at scale.
- Amazon Redshift: Cloud-based data warehousing.
6. Data Analytics
Definition: Data Analytics focuses on interpreting historical data to make better business decisions.
Examples of Data Analytics in Real Life:
- Retail: Identifying best-selling products.
- Sports Analytics: Improving player performance using data.
- Marketing: Understanding customer preferences.
Ongoing Projects in Data Analytics:
- Google Analytics: Website traffic analysis.
- Power BI & Tableau: Business intelligence tools.
- SAP HANA: Enterprise-level analytics.
