Trane is a software package that automatically generates problems for temporal datasets and produces labels for supervised learning. Its goal is to streamline the machine learning problem-solving process.

Install

Install Trane using pip:

python -m pip install trane

Usage

Here's a quick demonstration of Trane in action:

import trane
data, metadata = trane.load_airbnb() problem_generator = trane.ProblemGenerator(   metadata=metadata,   entity_columns=["location"] ) problems = problem_generator.generate()
for problem in problems[:5]:     print(problem)

A few of the generated problems:

================================================== Generated 40 total problems 
 Classification problems: 5 Regression problems: 35 ================================================== For each <location> predict if there exists a record For each <location> predict if there exists a record with <location> equal to <str> For each <location> predict if there exists a record with <location> not equal to <str> For each <location> predict if there exists a record with <rating> equal to <str> For each <location> predict if there exists a record with <rating> not equal to <str>

With Trane's LLM add-on (pip install "trane[llm]"), we can determine the relevant problems with OpenAI:

from trane.llm import analyze

instructions = "determine 5 most relevant problems about user's booking preferences. Do not include 'predict the first/last X' problems" context = "Airbnb data listings in major cities, including information about hosts, pricing, location, and room type, along with over 5 million historical reviews." relevant_problems = analyze(     problems=problems,     instructions=instructions,     context=context,     model="gpt-3.5-turbo-16k" ) for problem in relevant_problems:     print(problem)     print(f'Reasoning: {problem.get_reasoning()}\n')

For each <location> predict if there exists a record Reasoning: This problem can help identify locations with missing data or locations that have not been booked at all.

For each <location> predict the first <location> in all related records Reasoning: Predicting the first location in all related records can provide insights into the most frequently booked locations for each city.
For each <location> predict the first <rating> in all related records Reasoning: Predicting the first rating in all related records can provide insights into the average satisfaction level of guests for each location.
For each <location> predict the last <location> in all related records Reasoning: Predicting the last location in all related records can provide insights into the most recent bookings for each city.
For each <location> predict the last <rating> in all related records Reasoning: Predicting the last rating in all related records can provide insights into the recent satisfaction level of guests for each location.
