AUTOENCODIX

Autoencoders are deep-learning-based networks for dimension reduction and embedding by a combination of a compressing encoder and decoder structure for non-linear and multi-modal data integration, with promising applications to complex biological data from large-scale omics measurements. Current ongoing research and publications provide many exciting architectures and implementations of autoencoders. However, there is a lack of easy-to-use and unified implementations covering the whole pipeline of autoencoder applications. Consequently, we present AUTOENCODIX with the following features:

• Multi-modal data integration for any numerical or categorical data
• Different autoencoder architectures:
  • vanilla vanillix
  • variational varix
  • hierarchical/stacked stackix
  • ontology-based ontix
  • masking maskix
  • Image VAE (2D) imagix
  • cross-modal autoencoder (translation between different data modalities) x-modalix (works for multiple modalities paired and unpaired)
• A Python package with a scikit-learn-like interface

Requirements

• Python>=3.8 <3.13
• uv or another package manager (we recommend uv)
• git or gh

Installation

• gh repo clone jan-forest/autoencodix_package
• cd autoencodix_package
• uv venv --python 3.10
• source .venv/bin/activate
• uv sync

Sample Usage

import autoencodix as acx
from autoencodix.data.datapackage import DataPackage
from autoencodix.configs.vanillix_config import VanillixConfig
from autoencodix.configs.default_config import DataCase

# If your data is stored in pandas DataFrames, you can easily pass them to our custom DataPackage.
# For any tabular data that is not single-cell, provide it as a dictionary to the "multi_bulk" attribute of DataPackage.
# Note: "multi" might be misleading — it's valid to provide just one modality (1–n data modalities).
# Here, we assume paired metadata. If you have separate metadata for each modality, use the same dict keys as in multi_bulk, e.g.:
# annotation = {"rna": rna_annotation, "protein": protein_annotation}
my_datapackage: DataPackage = DataPackage(
    multi_bulk={"rna": raw_rna, "protein": raw_protein},
    annotation={"paired": annotation},
)

myconfig: VanillixConfig = VanillixConfig(data_case=DataCase.MULTI_BULK, epochs=30, device="cpu")
vanillix = acx.Vanillix(data=my_datapackage, config=myconfig)
result = vanillix.run()

Getting Started

We provide extensive tutorials for all of our use cases. The best place to start is the Vanillix Tutorial. Here, we explain the design and features of our pipeline, which applies to other pipelines. From there, you can explore the tutorials for the more specialized architectures (Varix, Ontix, etc). We also provide tutorials for each pipeline, but the Vanillix Tutorial explains the general concepts, while the other tutorials go into the specifics of the corresponding pipeline. For even more details on extra functionality, such as visualizing or customizing we provide deep dive tutorials for these topics. You can find the tutorials here:

• Best to get started: Vanillix Tutorial
• Tutorials for each specific pipeline (more advanced, do Vanillix first): Pipeline Tutorials
• Tutorials for specific extra functionality, see Deep Dives
