Integrate ArangoDB with PyTorch Geometric to Build Recommendation Systems
Estimated reading time: 20 minutes
In this blog post, we will build a complete movie recommendation application using ArangoDB and PyTorch Geometric. We will tackle the challenge of building a movie recommendation application by transforming it into the task of link prediction. Our goal is to predict missing links between a user and the movies they have not watched yet.

ArangoML Series: Multi-Model Collaboration
Estimated reading time: 8 minutes
Multi-Model Machine Learning
This article looks at how a team collaborating on a real-world machine learning project benefits from using a multi-model database for capturing ML meta-data.
The specific points discussed in this article are how:
- The graph data model is superior to relational for ML meta-data storage.
- Storing ML experiment objects is natural with multi-model.
- ArangoML promotes collaboration due to the flexibility of multi-model.
- ArangoML provides ops logging and performance analysis.
ArangoML Series: Intro to NetworkX Adapter
Estimated reading time: 3 minutes
This post is the fifth in a series of posts introducing the ArangoML features and tools. This post introduces the NetworkX adapter, which makes it easy to analyze your graphs stored in ArangoDB with NetworkX.
In this post we:
- Briefly introduce NetworkX
- Explore the IMDB user rating dataset
- Showcase the ArangoDB integration of NetworkX
- Explore the centrality measures of the data using NetworkX
- Store the experiment with arangopipe
This notebook is just a slice of the full-sized notebook available in the ArangoDB NetworkX adapter repository. It is summarized here to better fit the blog post format and provide a quick introduction to using the NetworkX adapter.
ArangoML Part 4: Detecting Covariate Shift in Datasets
Estimated reading time: 1 minute
This post is the fourth in a series of posts introducing ArangoML and showcasing its benefits to your machine learning pipelines. Until now, we have focused on ArangoML’s ability to capture metadata for your machine learning projects, but it does much more.
In this post we:
- Introduce the concept of covariate shift in datasets
- Showcase the built-in dataset shift detection API
ArangoML Part 3: Bootstrapping and Bias-Variance
Estimated reading time: 2 minutes
This post is the third in a series of posts about machine learning and showcasing the benefits ArangoML adds to your machine learning pipelines. In this post we:
- Introduce bootstrapping and bias-variance concepts
- Estimate and analyze the variance of the model from part 2
- Capture the metadata for this activity with arangopipe
ArangoML Part 2: Streamlining Machine Learning Workflows

(more…)ArangoML Pipeline Cloud – Managed Machine Learning Metadata Service
Estimated reading time: 4 minutes
We all know how crucial training data for data scientists is to build quality machine learning models. But when productionizing Machine Learning, Metadata is equally important.
Consider for example:
- Capture of Lineage Information (e.g., Which dataset influences which Model?)
- Capture of Audit Information (e.g, A given model was trained two months ago with the following training/validation performance)
- Reproducible Model Training
- Model Serving Policy (e.g., Which model should be deployed in production based on training statistics)
If you would like to see a live demo of ArangoML Pipeline Cloud, join our Head of Engineering and Machine Learning, Jörg Schad, on February 13, 2020 – 10am PT/ 1pm ET/ 7pm CET for a live webinar.
This is the reason we built ArangoML Pipeline, a flexible Metadata store which can be used with your existing ML Pipeline. ArangoML Pipeline can be used as a simple extension of existing ML pipelines through simple python/HTTP APIs.
Check out this page for further details on the challenge of Metadata in Machine Learning and ArangoML Pipeline.
ArangoML Pipeline Cloud
Today we are happy to announce a first version of Managed ML Metadata. Now you can start using ArangoML Pipeline without having to even start a separate docker container.
Additionally, as a cloud-based service based on ArangoDB’s managed cloud service Oasis, it can be up & running in just a few clicks and in the Free-to-Try tier even without a lengthy registration.
If you already have an existing notebook for your Machine Learning project it is as simple as adding the ArangoML Pipeline configuration pointing to our Free-to-Try tier `arangoml.arangodb.cloud` and a dedicated environment (aka ArangoDB database with custom login credentials) will be generated for you and persisted in the config.
SLAs
ArangoML Pipeline Cloud currently comes with two different service levels:
- Free-to-Try
The Free-to-Try tier allows for a no-hassle setup as it automatically configures your own environment based on a simple API call shown above and is ideas to test ArangoML Pipeline Cloud, but comes with no guarantees for your production data. - Production
If you are considering to use ArangoML Pipeline Cloud for production setup this is- Own Oasis cluster with all of Oasis Enterprise features
- Regular Backup
- It comes with a free 14-day trial period and afterwards follows the Oasis pricing model
Please reach out to arangoml@arangodb.cloud for sign-up and details.
How to get started
To show how easy it is to get started with ArangoML Pipeline Cloud in your existing ML pipeline we have a notebook with a modified TensorFlow Tutorial example with no setup or signup required!
If you are already using ArangoML Pipeline and just want to check how to migrate to ArangoML Pipeline Cloud we suggest to take a look at the minimal minimal example notebook.
While these notebook are mostly focused on the storing of metadata, we have a number of exciting notebooks with use-cases of how to further leverage and analyze metadata including for example datashift analysis.
