Study Notes
Business Analytics Overview
- Business analytics is the practice of leveraging data to inform decisions and enhance performance.
- Key benefits include data-driven decision making, competitive advantage, improved customer experience, cost reduction, and enhanced employee productivity.
Types of Business Analytics
- Descriptive Analytics: Analyzes past data to identify patterns and trends, summarizing historical performance.
- Diagnostic Analytics: Investigates reasons behind past events, identifying root causes of outcomes.
- Predictive Analytics: Utilizes historical data and statistical methods to forecast future events and trends.
- Prescriptive Analytics: Recommends actions to optimize outcomes through advanced algorithms and models.
CRISP-DM Framework
- CRISP-DM (CRoss-Industry Standard Process for Data Mining) ensures a reliable, repeatable data mining process.
- It consists of six phases: Business Understanding, Data Understanding, Data Preparation, Modeling, Evaluation, and Deployment.
CRISP-DM Phases
- Business Understanding: Define project objectives and data mining goals, assess the situation, and produce a project plan.
- Data Understanding: Gather initial data, assess quality, discover insights, and identify quality issues.
- Data Preparation: Takes up to 90% of the project time, involving data collection, cleansing, integration, and transformation.
- Modeling: Selection of modeling techniques, building the model, and assessment of model performance for optimization.
- Evaluation: Review model performance against business objectives, interpret its significance, and determine if additional business considerations are required.
- Deployment: Implement results in practice, plan for ongoing monitoring and maintenance, and produce final reports on outcomes.
Modeling Considerations
- Various modeling techniques can be utilized, such as decision trees or neural networks, depending on business goals.
- Model assessment includes validation against test data and collaboration with domain experts for practical interpretations.
Machine Learning Insight
- Machine Learning enables computers to learn from data autonomously, capable of handling complex tasks like pattern recognition and predictive analysis.
- Artificial Neural Networks are a subset of machine learning used for handling poorly structured problems and creating predictive models in various fields.
Challenges and Limitations
- Key challenges include data quality and availability, privacy issues, security risks, model limitations, and ethical concerns surrounding bias and fairness.
