Oloren ChemEngine

Oloren ChemEngine (oce) is a software package developed and maintained by Oloren AI containing a unified API for the development and use of molecular property predictors enabling

Direct development of high-performing predictors
Integration of predictors into model interpretability, uncertainty quantification, and analysis frameworks

Here's an example of what we mean by this. In less than ten lines of code, we'll train, save, load, and predict with a gradient-boosted model with two different molecular vector representations.

import olorenchemengine as oce

df = oce.ExampleDataFrame()

model = oce.BaseBoosting([
            oce.RandomForestModel(oce.DescriptastorusDescriptor("rdkit2dnormalized"), n_estimators=1000),
            oce.RandomForestModel(oce.OlorenCheckpoint("default"), n_estimators=1000)])
model.fit(df["Smiles"], df["pChEMBL Value"])

oce.save(model, "model.oce")

model2 = oce.load("model.oce")

y_pred = model2.predict(["CC(=O)OC1=CC=CC=C1C(=O)O"])

It's that simple! And it's just as simple to train a graph neural network, generate visualizations, and create error models. More information on features and capabilities is available in our documentation at docs.oloren.ai.

oce at a high level

Everything in oce is built around Oloren's BaseClass system, which all classes stem from. Any BaseClass derived objects has its parameters and complete state saved via parmeterize and saves respectively. A blank object (no internal state) can be recreated via create_BC and a complete object (with internal state) can be recreated via loads.

The system includes abstract subclasses of BaseClass are named Base{Class Type} and their interactions, most prominently

BaseModel, a base class for all any molecular property predictor

BaseRepresentation, a base class for all molecular representations

BaseVisualization, a base class for all types of visualizations and analyses

This abstraction system is provided free of charge by Oloren AI in the internals.

Getting Started with oce

Installation

In a Python 3.8 environment, you can install the package with the following command:

bash <(curl -s https://raw.githubusercontent.com/Oloren-AI/olorenchemengine/master/install.sh)

Feel free to check out install.sh to see what is happening under the hood. This will work fine in both a conda environment and a pip environment.

Basic Usage

We have an examples folder, which we'd highly reccomend you checkout--1A and 1B in particular--the rest of the examples can be purused when the topics come up.

Our Thanks

First, our thanks to the community of developers and scientists, who've built and maintained a repotoire of software libraries and scripts which have been invaluable. We'd like to particularly thank the folks creating RDKit, PyTorch Geometric, and SKLearn who've developed software we strive to emulate and exceed.

Second, we'd like to thank the amazing developers at Oloren who've created Oloren ChemEngine through enoromous effort and dedication. And, we'd like to thank our future collaborators and contributors ahead, who we're excited meet and work with.
