Study Notes
Big Data Analytics
- Big data analytics is the process of examining large and complex datasets to uncover patterns, trends, and insights.
- It involves collecting, storing, processing, and analyzing massive amounts of data from various sources.
- The goal is to extract valuable information that can be used to improve decision-making, optimize operations, and gain a competitive advantage.
Advanced Analytics Techniques
- Advanced analytics techniques go beyond basic reporting and descriptive statistics. They use sophisticated algorithms and models to uncover hidden relationships and predict future outcomes.
- Examples include:
- Predictive modeling: Predicting future events or outcomes based on historical data.
- Machine learning: Training algorithms to learn from data and make predictions or decisions.
- Deep learning: A type of machine learning that uses artificial neural networks to analyze complex patterns.
- Natural language processing (NLP): Understanding and processing human language.
- Prescriptive analytics: Providing recommendations for action based on data analysis.
Predictive Modeling
- Predictive modeling aims to determine the likelihood of future events or outcomes.
- It involves building statistical models that identify relationships between variables and use them to make predictions.
- Examples:
- Predicting customer churn
- Forecasting product demand
Big Data
- Big data is not limited to structured data. It can consist of various data types, including:
- Structured data: Organized in rows and columns like in a database.
- Semi-structured data: Has some organization but not as strict as structured data.
- Unstructured data: Does not follow a predefined structure.
- Big data is characterized by its volume, velocity, variety, and veracity.
Text Data
- Examples of text data include:
- Social media posts
- Customer reviews
- Email messages
- Website content
- Audio is NOT a type of text data.
Benefits of Big Data Analysis
- Companies like Amazon and Google benefit from big data analysis by:
- Personalizing customer experiences: Tailoring recommendations and offers to individual preferences.
- Improving operational efficiency: Identifying bottlenecks and optimizing processes.
- Developing new products and services: Gaining insights into market trends and customer needs.
Operationalized Analytics
- Operationalized analytics integrates analytics into a business process to enable real-time decision-making.
- It involves automating data collection, analysis, and reporting to ensure continuous insights and actionable information.
Basic Analytics
- Basic analytics focuses on descriptive analysis, summarizing and visualizing data to understand past trends and patterns.
- It includes reporting on key performance indicators (KPIs), creating charts, graphs, and dashboards.
Slicing and Dicing
- 'Slicing and dicing' refers to the ability to explore data from different angles using filters and dimensions.
- It helps to uncover hidden patterns and understand the relationships between variables.
Google and Big data analytics
- Google is particularly adept at big data analytics.
- They use it for:
- Search engine optimization
- Targeted advertising
- Predictive maintenance
Signal-to-Noise Ratio
- In big data, the signal-to-noise ratio refers to the proportion of meaningful data (signals) versus irrelevant data (noise).
- A high signal-to-noise ratio indicates that the data contains valuable insights, while a low ratio implies that the data is mostly noisy and difficult to analyze.
