Study Notes
In Vitro Fertilization (IVF)
- IVF involves collecting eggs from a woman's ovaries and fertilizing them with sperm (either the partner's or a donor's).
- Several embryos are produced.
- Some embryos are selected and transferred to the woman's uterus.
- The selection process aims to choose the "best" embryos, those most likely to survive.
- Selection is based on about 60 recorded features of the embryos.
- The large number of features makes it challenging for embryologists.
Data Mining in IVF
- Data mining is a technique for identifying patterns in large amounts of data.
- A research project in England is applying data mining to IVF data.
- This involves analyzing historical records of embryos and their outcomes.
- This approach can help to predict outcomes.
Data Mining in Dairy Farming
- Dairy farmers in New Zealand face tough business decisions yearly: keeping or selling cows.
- Typically, a fifth of the cows in a herd are culled annually.
- Factors such as breeding history, milk production, and age influence the decisions.
- Health issues (such as calving difficulties or health problems) impact the decision.
- About 700 attributes for each of several million cows have been recorded.
Data Mining in General
- Data is increasing rapidly (databases double every 20 months).
- The ability to understand and use data profitably decreases.
- Data mining finds patterns in electronically stored data.
Data Mining Defined
- Data mining is the process of finding meaningful patterns in large datasets.
- The process is often automated or semi-automated.
- The patterns must be useful and lead to advantages, usually economic.
- Data is usually present in substantial quantities.
Data Patterns
- Useful patterns allow predictions on new data.
- Patterns can be expressed as "black boxes" (incomprehensible innards) or "transparent boxes" (revealing patterns clearly).
- The patterns in data mining are often structural (explainable).
Contact Lens Prescription
- Data analysis can predict contact lens recommendations based on age, astigmatism, and tear production rate.
Decision Trees
- Decision trees are commonly used to express patterns and make recommendations.
- They specify the sequence of decisions needed and the resulting outcomes.
Contact Lens Data Limitations
- Datasets are likely to be incomplete in real-world applications, and generalizations are made from the data available.
- Actual datasets may contain unknown feature values, errors, or noise in data.
