How to Operationalize Any Machine Learning Algorithm

Many new ML engineers often find it extremely hard to manage data sets that are used to operationalize machine learning. Many are of the opinion that without a test data set or a firm validation set, it is impossible to take the next steps in machine learning projects. But, now things have changed. We are witnessing a massive influx of data that is influencing the pace, quality, and reliability of delivery of machine learning projects in a positive manner. ML courses are offering the latest training skills to handle new techniques in the deployment of machine learning projects with specific performance metrics that are at par with any industry-sponsored project in the data science domain.

Let’s explore the best practices in the operationalization of machine learning projects with good performance.

Distinguish between your datasets

If you are a beginner in the machine learning domain, you will be primarily working with either a test dataset or a training dataset. Only advanced ML analysts and engineers get a chance to work with the Validation dataset. Nonetheless, it is important to know the differences between all three datasets and how each of these influences the result of the Machine Learning project in the short term and long term implementation and deployment.

Train datasets also called as supervised trained Machine learning datasets (STML) are precursors to setting the ball rolling in any Machine learning project as these are used to “teach and train” Machine Learning algorithms to perform a set of tasks and actions based on input. In most cases, the training dataset would be analyzing labeled data that are more or less very much relevant to the kind of problems you plan to solve using ML algorithms. For example, if you are analyzing vehicle performance using test datasets, your training model would include data extracted from Engine performance, fuel consumption, mileage, and battery life expectancy.

Similarly, if you are developing a trained ML dataset for automated marketing and sales communications in social media or email channels, your data would consist of stats and feeds from Facebook, Twitter, LinkedIn, Salesforce, Hubspot, or any other source that can be used to mine and analyze the processes.

Once the ML algorithm is able to distinguish training data, it is the job of the ML engineer to move the ball to the next level – testing datasets, which is done using a host of processes and tools specifically created to handle testing / unlabelled data. Many data analysts also prefer to use testing data for dark data. A common hypothesis is when testing data is 100% identical to the training data, the final ML model would be successful.

But, in a practical scenario, this is hardly the case.

ML engineers often find enough room to build and fine-tune the training data sets that allow the Ml algorithms to deliver an unbiased and effective predictive analysis. Training is a one-time process, while testing is an iterative process. Best ML algorithms, however, are the ones that allow trainers to improve the test datasets with synchronous inclusion of train datasets as well so that ML algorithm keeps learning in an augmented fashion.

Validation Datasets in ML programming

Now, there is a third type of dataset that slices between the “test” and “train” sets.

It’s called the Validation dataset. For unbiased supervision of datasets, you require additional parameters, called hyperparameters to configure into your machine learning development.

For a large part of the ML development, you could be working with Python programming language, but in this particular phase, you would be doing a lot more R programming. R programming is used for cross-validation and easily integrates with the stages of data splicing, data testing, and data training using Regression Analysis and error detection models. These could involve testing and training with validation techniques with Mean Absolute Error or Root Mean Squared Error and R squared. Advanced validation datasets could also involve K-fold and LOOCV techniques that essentially ease the complex processes involved in the implementation and deployment of ML optimization models.

Automation Testing Automation testing is piloted by “regression” models that we discussed above in R programming techniques for the Cross-validation of datasets. Automation comes into the picture when you are performing backtesting and backward stepwise regression or backward elimination regression for ML optimization. Automated testing will not only allow ML analysts to back-test new inferences but also help design new ML models using the same set of trained datasets with improved efficiencies and refined demarcations for starting  ML model production.
