Quick Example (Complete Code)
Apply built-in lenses to extract statistical summaries from a dataset.
from sae_lens import Lens, Dataset
# Load dataset
ds = Dataset.load_from_csv("data.csv")
# Apply built-in lenses
statistical_summary = Lens.statistical_summary(ds)
print(statistical_summary)
Core Concepts
Main Functionality
- Define and Apply Custom Data Lenses: Create your own lens functions to perform specific data transformations.
- Use Built-in Lenses: Leverage predefined lenses for common tasks such as statistical summaries and time series analysis.
API Overview
The core classes in SAE Lens are:
Lens: A class for creating and applying custom lenses.Dataset: A class for handling datasets.
Example Usage
from sae_lens import Lens, Dataset
# Load dataset
ds = Dataset.load_from_csv("data.csv")
# Apply built-in lenses
statistical_summary = Lens.statistical_summary(ds)
print(statistical_summary)
# Define and apply custom lens function to filter data
def value_filter(x):
return x['Value'] > 100
custom_lense = Lens(value_filter)
filtered_data = custom_lense.apply(ds)
Practical Examples
Example 1: Applying Built-in Lenses
Apply statistical summary lenses to a financial dataset.
from sae_lens import Lens, Dataset
# Load financial data
financial_ds = Dataset.load_from_csv("financial_data.csv")
# Apply built-in lenses for statistical summaries
summary_results = Lens.statistical_summary(financial_ds)
print(summary_results)
Example 2: Custom Lenses for Data Filtering
Filter a dataset based on specific criteria using custom lenses.
from sae_lens import Lens, Dataset
def value_filter(x):
return x['Value'] > 100
# Load financial data
financial_ds = Dataset.load_from_csv("financial_data.csv")
# Define and apply custom lens function to filter data
custom_lense = Lens(value_filter)
filtered_financial_data = custom_lense.apply(financial_ds)
print(filtered_financial_data.head())
Best Practices
Tips and Recommendations
- Define Clear and Concise Lenses: Ensure your lenses are well-defined and easy to understand.
- Leverage Built-in Lenses for Common Tasks: Use predefined lenses where available to save time and effort.
- Optimize Performance: Utilize appropriate data types and avoid unnecessary recomputation of lenses.
Common Pitfalls
- Avoid Unnecessary Recomputation: Computed lens results should be cached to avoid redundant calculations.
- Ensure Compatibility with Python Versions: Stay up-to-date with the latest Python versions for optimal performance.
