Best Tools for ML Model Governance, Provenance, and Lineage

ML software development is complex; building an ML model is one thing, improving and maintaining it, is another. If you want your machine learning models to be robust, compliant, and give reproducible results, you must invest time and money in quality model management. 

Model governance, model provenance, and model lineage tools help you in doing just that by tracking model activity, recording all changes in the data and the model, and outlining best practices for data management and disposal. 

In this post, let us discuss what these tools are and how to choose the best ones. While these three practices are meant for different things, they have a lot in common. So a tool that is good for, say model governance, is usually great for the other two as well. 

I will guide you through some of the most popular tools for model governance among developers and explain which one you should choose based on your particular use case. 

What is model governance?

Model governance, as you might understand from the term, is a set of practices and techniques that provide for controlling the process of model development and implementation. Any ML model is bound to comply with certain expectations. They should meet technical requirements, be legally compliant, and not present any ethical concerns. 

Why model governance? 

It is quite common that after the model is deployed, the results in the real world are pretty different from what you were expecting. To understand where things possibly went wrong and quickly fix that, you need model governance. 

You must be familiar with the term ‘black box’ concerning ML models, especially deep learning models. They are described as mysterious and impossible to debug. However, once you have a catalog of all modifications that ever happened, it becomes much easier to ensure the proper functioning of the model. 

For example, a common problem in the last few years that has invited a lot of backlash from the community is models producing biased results on getting fed biased data. The Amazon AI hiring system is often cited as an example of biased AI. The system penalized resumes that included the word ‘women’s’ in them like in ‘women’s chess club’ because historically, it was men who occupied the majority of positions.

If you don’t want your company to end up on the ‘blacklist’ together with Amazon, Google, and Facebook, who have been widely criticized for their discriminatory models, the ability to track data drifts, anomalies, and biases can be beneficial. 

Moreover, biases are not the only kind of problem that your model may face. Another challenge is to guarantee the security of a model, especially if we’re talking about enterprise-level companies. If a model is accidentally exposed to another department inside your company or third parties, there can be a lot of uncertainty. For example, models can be tampered with and that can put the enterprise at risk. 

Benefits of model governance

Model governance has apparent benefits. However, it is not always easy to implement it from scratch. You will need to review the workflows of the ML team first to evaluate effectiveness and cost demands. The most important thing about model governance implementation is consistency. You have to use model governance across all models and departments, not just to a few business units. Standardization is the key to effective model governance. 

What is model provenance?

Model provenance is tightly connected to the model governance process and describes the origin of the model and the processing steps that were applied to it. 

Why model provenance?

Usually, before you start working with an ML model, you have to prepare the training data which has to go through a long transformation process along the machine learning development pipeline. The idea of data provenance is to keep track of every step of transformation: where the data came from, who altered it, and in what manner. Data acquisition, merging, cleaning, and feature extraction belong to the camp of data provenance. 

Benefits of model provenance

Models go through a lot of changes before the final version is deployed. The process usually involves experimentation with different ML techniques and architectures to get the best results. You can’t always predict whether your next approach will be fruitful or not. And it can be hard to get back to the point of optimal performance in the absence of the model’s checkpoints. Model provenance tools help you track all the inputs (including data), hyperparameters, dependencies, and more.

Documenting all these things can be a solution, but it is not very convenient in the case of large projects. Moreover, the human factors can always put your model provenance at risk: developers often forget to record something small such as metadata notes, and their negligence can result in substantial monetary losses. 

Therefore, it is worth investing in automated solutions in the form of model provenance tools. It is particularly helpful for companies because it helps to enhance visibility. You have a map of your model at hand and can forget about ‘visibility debt’. 

What is model lineage?

Model lineage is another technique of enhancing the visibility of your model. It keeps the history of your model in check. If you use automated tools, which are highly recommended for routine tasks, the records will be automatically generated each time a new version of the model is trained. 

Among the information that model lineage tools allow you to keep, is data about the kind of data and algorithms used for building the model, the pipeline used for training, and chosen parameters.

Why model lineage?

ML model development is a field that requires experimentation. It usually takes weeks, if not months, to come up with the right combination of model configurations and hyperparameters. Usually, researchers work in iterations, keeping what works best from the previous version of the model and alternating what needs to be changed. Moreover, there are usually many training datasets involved that can be changed along the ML development pipeline.

When you finally settle down for the final version of the model, it can be hard to track down what alterations actually contributed to this success. However, it’s important to understand this not only for the research purposes but also for the continuous reproducible results of the model. In addition, researchers usually work as part of the team and sometimes even collaborate with other teams and departments. Keeping records in spreadsheets is not very sustainable and doesn’t scale very well.  

When a need for collaboration rises, it is always better if you use version control tools for better model traceability. Knowing the history of the model makes the experiment results reproducible which is highly valued in both business and academic fields. Via Model lineage tools it will be possible to trace the relationship between a model and its components, including experiments, datasets, containers, etc. They help to represent the associations between the artifacts and the core and show the structure in an intuitive, visual way. 

Benefits of model lineage

Model lineage is essential for the transparency and traceability of any company. Today your ML model cannot simply represent a ‘black box’. For example, if third parties raise legal or ethical concerns, you will be able to share all the nitty-gritty details of the model. You should be able to trace back to the point where questionable parts were introduced and by whom and be able to explain and fix it.

Moreover, model lineage is crucial in science and business. The results that your model shows should be reproducible. Your client or your colleagues should be able to run the model and get the same result. It is much easier to build and deploy a stable model when you have all the data about its history and development.

How to choose the right tool 

Now that the difference and similarities between model governance, model provenance, and model lineage are clear, let us discuss how to choose the right tool for your company. 

If you have decided to transition to a model governance tool, the first thing you do is not to reach out to the software vendors. In fact, this is the last thing you should do. Here is what you can do instead step-by-step:

  • Model governance adoption: Take your time and evaluate what outcome your organization is trying to achieve. The best answer is the concrete answer, for example, ‘Deliver quality data to increase revenue by X thousands of dollars’. Your milestones should be precise and measurable; only then will you be able to monitor the efficiency of your model governance adoption after some time. 
  • Operating model discovery: An operating model is a tool that will help you to outline the roles, responsibilities, and business terms in what concerns model governance. For example, it will establish data owners, individuals who decide how the company should use the data, and data stewards responsible for data collecting and processing. You will also need to develop a set of data governance policies, aka rules that your team must follow. 
  • Selection of the best tools: The best data governance tool will automate as much as possible and provide maximum customization because every company is different. Don’t be afraid to talk to vendors and ask them to demonstrate their solutions and highlight essential features. Come to the meeting prepared: you have your goals and requirements and ask how the product will help you fulfill them. 

Often you will have to compromise. For example, a solution that contains every feature you need and more might be too expensive. In this case, consider how important the part is for your ML engineering team. It is nice to have the features ranked in advance: for some teams, it is crucial that the solution supports the cloud; for others, not really. Just because everyone is working in the cloud doesn’t mean you have to. 

A great way to prioritize features is to ask yourself and your team whether you often perform the tasks you want to automate. And if the answer is no, perhaps the costs of achieving them manually are lower than automation.

Best 7 Data Version Control Tools That Improve Your Workflow With Machine Learning Projects

5 mins read | Jakub Czakon | Updated October 20th, 2021

Keeping track of all the data you use for models and experiments is not exactly a piece of cake. It takes a lot of time and is more than just managing and tracking files. You need to ensure everybody’s on the same page and follows changes simultaneously to keep track of the latest version.

You can do that with no effort by using the right software! A good data version control tool will allow you to have unified data sets with a strong repository of all your experiments.

It will also enable smooth collaboration between all team members so everyone can follow changes in real-time and always know what’s happening.

It’s a great way to systematize data version control, improve workflow, and minimize the risk of occurring errors.

So check out these top tools for data version control that can help you automate work and optimize processes.

Data versioning tools are critical to your workflow if you care about reproducibility, traceability, and ML model lineage. 

They help you get a version of an artifact, a hash of the dataset or model that you can use to identify and compare it later. Often you’d log this data version into your metadata management solution to make sure your model training is versioned and reproducible.

How to choose a data versioning tool?

To choose a suitable data versioning tool for your workflow, you should check:

  • Support for your data modality: how does it support video/audio? Does it provide some preview for tabular data?
  • Ease of use: how easy is it to use in your workflow? How much overhead does it add to your execution?
  • Diff and compare: Can you compare datasets? Can you see the diff for your image directory?
  • How well does it work with your stack: Can you easily connect to your infrastructure, platform, or model training workflow?
  • Can you get your team on board: If your team does not adopt it, it doesn’t matter how good the tool is. So keep your teammates skillset in mind and preferences in mind. 

Here’re are a few tools worth exploring.
