Lightwood is Legos for Machine Learning.

Last update: Jan 08, 2023

Overview

Lightwood is like Legos for Machine Learning.

A Pytorch based framework that breaks down machine learning problems into smaller blocks that can be glued together seamlessly with one objective:

Make it so simple that you can build predictive models with as little as one line of code.

Documentation

Learn more from the Lightwood's docs.

Try it out

Installation

You can install Lightwood from pip:

pip3 install lightwood

Note: depending on your environment, you might have to use pip instead of pip3 in the above command.

Usage

Given the simple sensor_data.csv let's predict sensor3 values.

sensor1	sensor2	sensor3
1	-1	-1
0	1	0
-1	- 1	1

Import Predictor from Lightwood

from lightwood import Predictor

Train the model.

import pandas
sensor3_predictor = Predictor(output=['sensor3']).learn(from_data=pandas.read_csv('sensor_data.csv'))

You can now predict what sensor3 value will be.

prediction = sensor3_predictor.predict(when={'sensor1':1, 'sensor2':-1})

You can also try Lightwood in Google Colab:

ImportError: cannot import name 'Imputer' from 'sklearn.preprocessing'
Describe the bug Installing the latest version of lightwood throws ImportError. I guess the issue is related to the sciki-learn.

To Reproduce Steps to reproduce the behavior:

Train model, the issue is not related to a specific dataset

CSV with the dataset from the deernet paper

I loved this paper: https://arxiv.org/pdf/2106.07465.pdf and I'd love to add the dataset they are using to our benchmark.

However, I'm unsure how to use the physics library required to generate the data and would rather just have a simple CSV with the data (csv columns can contain arrays if need be, but I don't think this will be required here).

Feel free to PR this csv into https://github.com/mindsdb/benchmarks

This will count 3 points towards the hacktoberfest deep learning laptop raffle.

quantum mixer implementation
closes #641

implementing a quantum class neural network from https://qiskit.org/textbook/ch-machine-learning/machine-learning-qiskit-pytorch.html

implementation notes

currently using QClassic wrapper around the Neural mixer

its easier to error out the unit test

because qiskit is an optional dependency

QClassicNet is quite rudimentary

returns a quantum modified value as per the tutorial

Add new ensembles that improve accuracy on the benchmark suite
Task

Lightwood's core component is the encoder, which takes the predictions from the mixers and combines the final prediction.

This task involves implementing any ensemble which you think can improve lightwood's accuracy. A PR will be accepted as long as the relative accuracy is increased by at least 1% with no modifications other than adding the new ensembles and using it in json_ai.py.

Multiple people can try this PR assuming no plagiarism between the designs.

Steps :male_detective: :female_detective:

Fork the Lightwood repository, checkout the staging branch and from it create a new one.

Implement your custom ensemble and edit the api/json_ai.py file to replace the BestOf ensemble

Run the benchmarks following the instructions here

Note: If you can't afford to run all the benchmarks, test on a subset of small datasets you think your ensemble is good at using --datasets=x,y,z | Alternatively, contact us (or make a PR) and we will provide compute for you to do this.

Make the PR and address any comments that reviewers might make.

Implement an audio encoder
Task

Lightwood handles many different data types, and we're always looking to include more.

One possible data type to experiment with is an audio encoder; if you are interested in tackling this, please ping the research team (either me, @hakunanatasha or @George3d6) in the discussion here, to propose your initial approach and scope your contribution together ✨.

Ensure you implement a unit test plus any modifications needed to obtain an encoded representation from audio in order for this PR to be accepted.

Steps :male_detective: :female_detective:

Fork the Lightwood repository, checkout the staging branch and from it create a new one.

Implement a unit test that generates an instance of your encoder, some (potentially synthetic) audio data, and proceed to encode-decode it. This unit test can be useful as a reference, and the (outdated) AmplitudeTs encoder as inspiration or starting point for your own encoder (in fact, feel free to replace it).

Accuracy of the encoder is to be discussed with our team, so don't get discouraged if encoded representations are not perfect; this is a hard problem!

Make the PR and address any comments that reviewers might make.

Additional rewards :1st_place_medal:

Each encoder PR brings 5️⃣ points for entry into the draw for a :computer: Deep Learning Laptop powered by the NVIDIA RTX 3080 Max-Q GPU or other swag :shirt: :bear: . For more info check out https://mindsdb.com/hacktoberfest/

[docs] Optional classes are not documented

The automated doc system is not picking up the docstrings in classes that require optional dependencies. For example, the mixers LightGBM, LightGBMArray and NHitsMixer.

We should either change the CI to install all extra deps or change the doc system to pick up these classes regardless of whether the dependencies are installed or not.
