What Is ModelOps and How Is It Different From MLOps?

In the past few years, we’ve seen an increase in Artificial Intelligence and Machine Learning solutions in real-life situations. In big companies, these solutions have to be implemented in hundreds of use cases and it’s difficult to do this manually. 

At the enterprise level, the deployment of AI solutions and machine learning models needs to be operationalized. Data scientists and ML engineers have tools to create and deploy models but that’s just a start. The models need to be deployed in production to deal with real-world use cases. So, we need a framework or methodology to reduce manual effort and streamline the deployment of ML models. That framework is ModelOps.

It was proposed in December 2018 by IBM researchers as “a programming model for reusable, platform-independent, and composable AI workflows”. The authors, Waldemar Hummer and Vinod Muthusamy, later expanded on the idea as a “cloud-based framework and platform for end-to-end development and lifecycle management of artificial intelligence (AI) applications”.

“Artificial intelligence (AI) model operationalization (ModelOps) is a set of capabilities that primarily focuses on the governance and the full life cycle management of all AI and decision models. This includes models based on machine learning (ML), knowledge graphs, rules, optimization, natural language techniques and agents. In contrast to MLOps (which focuses only on the operationalization of ML models) and AIOps (which is AI for IT operations), ModelOps focuses on operationalizing all AI and decision models.” – Gartner

In March 2020, ModelOp, Inc. published the first comprehensive guide to ModelOps methodology. The guide covered what ModelOps can do, along with technical and organizational requirements for implementing ModelOps practices. 

Basically, ModelOps is a collection of tools, technologies, and best practices to deploy, monitor and manage machine learning models. It is the key capability for scaling and governing AI at the enterprise level. 

It’s based on the concept of DevOps but adapted to ensure good quality of machine learning models. In general, ModelOps includes:

• continuous integration / continuous delivery (CI/CD), 
• development environments, 
• testing, 
• model versioning, 
• model store,
• rollback, etc. 

You can think of ModelOps as an expansion of MLOps, with the main focus to keep deployed models ready for the future with continuous re-training and synchronized deployments.

“A true ModelOps framework allows you to bring standardization and scalability across these disparate environments so that development, training and deployment processes can run consistently and in a platform-agnostic manner.” – cio-wiki

Why ModelOps? The key to enterprise AI

In 2018, Gartner asked large enterprises about AI adoption. Managers had expected 23% of their systems to have AI integrated by the following year. Gartner followed up in 2019 and found that only 5% of deployment made it to production. Most enterprises were unable to quickly scale and integrate AI into their systems.

This buildup of undeployed models can eventually affect company growth. Models need complex re-training. For each new line of business, a new set of data. Plus, models need to be placed into a 24/7 operational environment, as most data scientists use open-source modelling tools like Jupyter notebook or R studio. Data scientists are not aware of or don’t have access to environments where latency can be observed. 

This is where ModelOps comes into the picture. It can help solve these challenges and enable organizations to scale and manage AI initiatives easily. 

“Models are profoundly accountable to the business, more so than traditional software. They have to go under regulatory scrutiny and compliance. A properly operating model can dramatically change the topline performance of a particular business unit. So, integration between the business units and compliance departments is critical.” – Forbes

In the past years, enterprises have seen a surge in AI development. But, as one survey shows, “84% of C-suite executives believe they must leverage artificial intelligence (AI) to achieve their growth objectives, yet 76% report they struggle with how to scale.”

ModelOps excel in the dynamic environment. The model can be easily adjusted whenever the defined condition changes. Enterprises incorporate different types of models for different business problems. ModelOps enables them to switch or scale the systems accordingly.

ModelOps is like a bridge between data scientists, data engineers, application owners, and infrastructure owners. It fosters dynamic collaboration and improved productivity. Enterprises use ModelOps to solve challenges like:

• Regulatory Compliance – To comply with regulatory requirements, we need systematic reproduction of training, evaluation, and scoring of each model. Model monitoring helps to enforce compliance gates and controls ensuring that all the business and regulatory requirements are satisfied. 
• Silos Environment – Multiple teams are involved in a model when it goes from deployment to monitoring. Ineffective collaboration across teams can make scaling AI difficult. Teams need to come together, and ModelOps helps to create an environment where models can easily be moved from the data science team to the IT production team.
• Different models have different solutions – Enterprises will have hundreds of models for different business problems. Each model accounts for specific business process variations, unique customer segmentations, etc. ModelOps provides a single view to see workflows, auditing, performance tuning, and governance to control cost and create value.
• Complex Technology – A wide range of solutions, tools, and technologies are available for data and analytics problems. It’s difficult to manage all of them with continuous innovations. Even the most expert teams might not keep up. ModelOps makes it easier to integrate and adopt new technologies. 

ModelOps use cases

Many managers have struggled to demonstrate the value of analytics because analytics solutions often don’t make it to production. ModelOps can solve this. 

Here are some of the areas where ModelOps is being used extensively to overcome model deployment challenges:

• Finance – For example, banks have been doing credit approval using statistical models, and today most operational decision-making is driven by real-time analytics. This model-based approach has helped banks to reduce man-hours, but managing these complicated models at scale is also difficult. These models should be fair and robust, which fosters unbiased decisions. ModelOps makes it easier to monitor the model for bias or anomalies and to update them accordingly.
• Healthcare – AI can improve efficiency and patient care while reducing costly administrative errors. But, machine learning models have to be refreshed with current data, new KPIs, etc. Also, monitored to review anomalies. The updated models should be readily available on different systems, for example, a mobile app or a system at the lab, to keep the results in sync. 
• Retail – When covid-19 hit, everything had to move online, but it was difficult to deploy and monitor AI solutions effectively. ModelOps provides an ability to monitor the models, and create a multilevel view of key metrics to see model performance in production. To understand the areas of growth and reduce work for data scientists and IT specialists, retail companies opted for automation and standardization of ML operators. Companies, like Domino’s Pizza, were able to increase the efficiency of managing multiple models at scale.

ModelOps platforms

There are several online hubs available to guide enterprises through the model lifecycle. Some of the most commonly used platforms are:

1. ModelOp

In 2016, ModelOp was founded to address the large gap between deployment and maintenance of models. To operationalize machine learning models, the team came up with ModelOp Center. Center helped to accelerate the operationalization of models with ensured governance, and enforcement of regulatory requirements.

“ModelOp Center automates the governance, management and monitoring of deployed AI, ML models across platforms and teams, resulting in reliable, compliant and scalable AI initiatives.”

ModelOp Center can help you accomplish the steps involved in a model’s life cycle:

1. Register – In ModelOp center you can register the model using the Jupyter plugin or CLI, and passing the information through predefined elements – Model Source, Attachments, Schemas and Model Platform. The source code of the model can be divided using 4 functions – Init, Scoring, Metrics and Training. 

You can also update the registered model whenever you want by editing schemas or adding new assets to it.

2. Orchestrate – ModelOp Center has an MLC (Model Life Cycle) manager which automates model operations, like deployment, monitoring, and governance. The model can be deployed and monitored in production efficiently and easily. This also gives enterprises flexibility to automate only a portion of the lifecycle. 

MLC manager is a framework that executes, monitors, and manages MLC processes. MLC processes are triggered through external events, like:

1.  Time-based
2.  Data arrival
3.  Notifications
4.  Manual Intervention
5.  Marked as – Ready for production

A few common MLC processes can be handled using the ModelOp Center: productionization, refreshing, retraining, and monitoring performance. 

3. Monitor – ModelOp Center provides various metrics for comprehensive model monitoring. You can evaluate models using common metrics like F1 score, ROC, AUC, etc. By using SLA or data metrics, you can also monitor operational, quality, risk, and process performances.

4. Govern – A central repository for governing each step of the model lifecycle. Governance ensures a standard representation of a model. Stakeholders can look at production model inventory to view details, modify and improve the model, or operationalise a process. 

ModelOp Center is also integrated with many development platforms, IT systems and enterprise applications. These integrations can be leveraged to extend AI investments and unlock the value of AI. 

With platforms like ModelOp Center, enterprises can accelerate model deployment time and reduce business risks.

• Economic – ModelOps platforms are integrated with the cloud, which can help to optimize cloud service and AI models economically. Enterprises can choose flexible consumption of services for modelling. 

Features of ModelOps

We have covered some of the ModelOps tools in the previous section, and most of them have common features, as they all serve one goal – to operationalize models. 

ModelOps is the key to unlock value, it’s the connective tissue in your AI tech stack. Let’s look at some of the features and see why ModelOps matters:

• Generating Model Pipeline – With the least human interaction and a few clicks, ModelOps platforms generate a pipeline automatically. Once the first setup is done, the whole modelling lifecycle – preparing data, selecting models, feature engineering, hyperparameter optimization – will be automated.
• Monitoring Models – Monitoring hundreds of different models can be challenging. ModelOps helps to monitor all kinds of models. It looks for any possible bias and then learns how to resolve it.
• Deploying Models – The models built on ModelOps platforms can be integrated into any application easily. You can deploy and send models virtually anywhere.
• One-stop solution – Build, Run and Manage Models – Data scientists build models using open-source platforms like Jupyter, R, etc. Then IT professionals use a different platform to deploy these models in production. This process usually takes time and reduces the time to market. ModelOps platforms are here to rescue enterprises with this complicated and lengthy process. They are the one-stop solutions where teams can build models, run, and manage them easily. 

Is ModelOps the same as MLOps?

There is a thin line between ModelOps and MLOps and if you look at their architecture you might see ModelOps as an extension of MLOps. ModelOps refers to the processes to operationalize and manage AI models in use in production. ModelOps can be seen as SDLC that helps to organize the life cycle flow, i.e creating a model, testing, deploying, and monitoring it.

ModelOps does everything MLOps does and more. It helps enterprises to get more out of their AI investments. MLOps enables data scientists and IT professionals to collaborate and communicate effectively while automating machine learning models. ModelOps is an evolution of MLOps, focused on continuous retraining, synchronized development and deployment of ML models, decision optimization, and transformational models. 

“ModelOps has emerged as the critical link to addressing last mile delivery challenges for AI deployments. ModelOps is a superset of MLOps, which refers to the processes involved to operationalize and manage AI models in use in production systems.” – Modzy
