Machine Learning Roadmap

Design by Miguel Norberto

Machine learning is a process of programming computers to learn from data without being explicitly programmed.

The artificial intelligence (AI) subset enables computers to understand and improve from experience. Machine learning algorithms can be used to make predictions or decisions, such as whether or not a credit card transaction is fraudulent.

Machine learning algorithms: supervised and unsupervised learning

supervised learning algorithms are those that learn from a set of input data that has been labeled with the desired output. The algorithm is “trained” on this data, and it can then be used to predict the production of new, unlabeled data. Supervised learning algorithms can be divided into two categories: classification and regression.

Unsupervised learning algorithms are those that don’t have any labeled input data. Instead, they are given only the input data itself. Unsupervised learning aims to find patterns in the data and then group them accordingly. This process can help uncover hidden relationships in the data that would be difficult to spot otherwise.

Data pre-processing: feature extraction and selection

Data pre-processing is a critical step in many machine learning pipelines. This step can involve feature extraction and selection, which are used to reduce the size of the data set and improve the models’ performance. Feature extraction refers to extracting relevant information from the data set. In contrast, feature selection refers to selecting a subset of features that will be used in the model.

There are a number of different techniques that can be used for feature extraction and selection, and the approach that is used will vary depending on the type of data set and the type of model used. Some standard techniques include:

  • Correlation analysis: This technique can be used to identify relationships between different features in the data set.

Model training and validation: parameter tuning, cross-validation, and hyperparameter optimization

Parameter tuning, cross-validation, and hyperparameter optimization are three essential aspects of model training that allow you to get the most out of your machine learning models.

By adequately tuning your parameters, you can improve the accuracy of your models and reduce the risk of over fitting. Cross-validation helps you evaluate your models more accurately and determine their generalization performance. Finally, Hyperparameter optimization allows you to find the best set of hyper parameters for your models, resulting in improved performance.

Deployment and inference: choosing a model deployment strategy, deploying models in the cloud, and monitoring model performance

Machine learning models can be deployed in various ways, depending on the needs of the application. In some cases, the model is deployed as part of the application itself. In other cases, the model is deployed separately from the application, and the application calls the model to get predictions.

One common deployment strategy is to deploy the model in the cloud. This has several advantages: it makes it easy to scale up or down as needed, and it eliminates the need to install and maintain software on your machines. Another advantage of deploying in the cloud is that you can often use a pay-as-you-go pricing model, which means you only pay for what you use.

It’s important to monitor model performance when deploying in the cloud. One way to do this is to use a tool like Google Cloud Platform’s Monitoring Console.


Machine learning is a powerful tool that can improve and optimize many different aspects of our lives. However, it is important to remember that machine learning is still in its early stages, and many challenges need to be addressed before it can be fully utilized.

We hope that this roadmap provides a better understanding of the current state of machine learning and its potential future applications.
