What Are Machine Learning Operations?

Table of Contents

Machine Learning Operations (MLOps) is the process of solving problems in a machine learning system. This includes Model inference, Model review, and Model deployment. The key to successful MLOps is to understand the bottlenecks in the system. Once you understand them, you can begin solving them.

Data validation

When you’re developing and deploying machine learning (ML) solutions, you’ll need to make sure your data is clean and accurate. This means building and using data validation tools. Each has their own advantages and disadvantages. These tools can be built locally or can be customized to the needs of new ML projects.

Data validation is necessary for a variety of reasons. For example, if real-world data is fed into a training pipeline, it may not contain the variable of the desired outcome. For example, a SQL database containing subscription transactions may not contain a column that indicates whether the subscription was renewed. However, subsequent transactions may indicate whether the subscription was cancelled or continued.

Machine learning systems require data validation, but this isn’t always an easy task. There are many factors that can affect the performance of a model, including poor data quality, successively added data, and differences in code stacks. Data validation can be done in three main steps, using data linter tools.

Data validation ensures the quality of new data and accuracy of data from previous datasets. It can also check new data sets, which are used to retrain ML models. It can help detect data gaps in the training dataset or identify anomalies.

Model review in machine learning operations

The design process of machine learning operations should include a review of the model outputs by a human. The model-development team should determine the threshold of certainty for a decision. Once a decision has been made, the machine will be free to handle the process with full autonomy. Leading organizations have incorporated this step into their processes. As a result, their models’ accuracy has increased steadily. They went from having less than 40 percent accuracy at the time of the first review to more than 80 percent within a few months.

Model review stages are not as simple as they sound, however. Model review processes should be structured in a manner that minimizes clashes. It is critical to coordinate with the different disciplines to avoid conflicts in model review. If clashes exist, they must be resolved by the team. A standardized process for this review can help to ensure that all stakeholders are satisfied with the model.

Model inference in machine learning operations

The use of model inference in machine learning operations involves the creation of models, which are then deployed to production environments. This process can be done in either batch or on-line inference modes. In batch inference, the model is executed as a scheduled job and results are emailed to the user. On-line inference, on the other hand, is triggered by a web application that invokes the model via an HTTP endpoint.

The model inference phase of machine learning operations is a separate process from the model training phase. It is an integral part of the machine learning model lifecycle, and requires different specialist skills. When used correctly, machine learning model inference results in an accurate and efficient model. To understand the model inference process, let’s first define what it is.

Inference workloads may be highly resource intensive, and they require powerful hardware, such as CPUs and GPUs. For this reason, the cost of inference is an important consideration. In some cases, it may be better to run the models in a batch environment.

Model deployment

The model deployment process is critical to ensuring that the model is functioning effectively and making the right predictions. During the deployment process, it is crucial to keep track of metrics so that you can detect problems and improve your model. Also, it is important to monitor the data feed and ensure that all end users are trained properly before deploying the model.

Deploying models into production environments requires a lot of time. There are two main ways to do this: online inference and batch inference. Online inference involves scheduling a job to run the model periodically and providing results via email. Batch inference allows you to deploy a model in batches, allowing for higher model complexity.

Several model development platforms exist today, such as MLflow and DVC. These frameworks allow you to create and deploy deep learning models. ML models can be packaged and deployed with a feature store or a data repository. Model registries can also help you compare a model’s performance with previous versions. A model registry can also help you track the model’s progress by storing its artifacts and the training environment.

ML applications involve sensitive information such as personally identifiable data or protected health information. As a result, it is critical to consider the risks associated with bad model behavior. Erroneous output can have a financial, reputational, and security impact. As a result, it may be necessary to implement extra safeguards to protect against any erroneous output.

Model monitoring

Model monitoring is a critical process that helps track and debug model performance changes. The most straightforward method of monitoring is to continually evaluate a model’s performance against real-world data. This process can be enhanced by setting up customized notifications that notify you of any significant changes. If a model begins to degrade, model monitoring can alert you and trigger retraining.

The importance of model monitoring in production cannot be overstated. Previously, many ML/AI teams relied on manual processes to monitor model performance and identify problems. These processes are time-consuming and often make it difficult to pinpoint underlying causes and fix problems. Many ML/AI teams struggle with manual processes and siloed monitoring tools.

Model monitoring involves closely monitoring ML models in production to detect problems and potential errors before they negatively affect the business. A robust MLOps infrastructure should be able to monitor model performance, data relevance, accuracy, and trust elements to ensure that the model is working as intended. Furthermore, it should also be able to monitor the business impact of the model.

Model monitoring during machine learning operations (MLLOps) is an essential step in the production cycle of ML models. Models are frequently created collaboratively, and data scientists often use experiments and notebooks created by others. This increases the complexity of reproducing desired results. By implementing ML Model Monitoring, organizations can easily monitor and debug ML models.


To be successful in machine learning operations, data scientists from different companies need to collaborate closely. This means establishing a collaboration culture among teams and reducing domain silos. Collaboration in ML operations requires a data monitoring component, an automated ML workflow pipeline, and continuous evaluation of ML models. In addition, collaboration should be supported by a data governance framework and tools that span multiple business units.

Collaboration in machine learning operations is important because teams can work on multiple projects simultaneously. This way, different team members can use different tools and write scripts to glue everything together. In addition, this allows different team members to take ownership of the work and identify potential problems. Without collaboration, a project could suffer from low quality, a longer timeline, and low team morale.

Collaboration in machine learning operations can improve the results of machine learning projects and help organizations reduce their operational costs. Additionally, it can help build trust among employees towards data science initiatives and improve data-driven business decisions. To achieve this, organizations should implement a version control system, such as Git, Subversion, or Mercurial. This ensures that code and data processing are consistent and that team members can easily discover each other’s previous work. In addition, collaboration can make it possible to reuse ML models and features across the organization.


Machine Learning Operations (MLOps) is a set of processes and practices that helps maintain machine learning algorithms in production environments. These processes and tools are inspired by DevOps, a set of practices that has evolved from decades of experience managing complex software products. Like regular software, data science has its quirks and can be difficult to maintain. Its performance and behavior are dependent on its source code, the data used to train it, and the data that flows through it.

The tools used in machine learning operations include the following: – ML frameworks and libraries for data science projects. – Support for cloud platforms and infrastructure tasks. – Support for multiple ML models. – Model-as-a-Service is a good approach if you plan on building a machine learning framework and model using multiple services. Some tools package models automatically using Docker images. Others offer special model servers such as TensorFlow Serving, Clipper, and Kubeflow. – Data versioning: Data scientists should consider using data versioning tools to save artefacts and experiments. Data versioning can help them reuse and replicate their experiments.
