Study Notes
- A machine learning model is said to be underfit when it treats true parameters as noise and fails to identify actual patterns and relationships.
- An overfit model identifies spurious relationships.
- Labeling input data relates to supervised or unsupervised machine learning techniques.
Big Data Characteristics
- Big Data is characterized by volume, velocity, and variety.
- Volume refers to the amount of data available.
- Velocity refers to the speed at which data are communicated.
- Variety refers to the degrees of structure in which data exist.
- Terabyte is a measure of volume.
- Latency refers to velocity.
Fintech Forms
- Text analytics analyzes unstructured data in text or voice forms
- Text analytics can find the frequency a word appears in documents.
