What is Machine Learning?

Machine Learning

Machine learning is the study and design of self-improving systems that maximize a specified aim. Instead of being a set of instructions written by a human expert, a machine learning system accomplishes its goal through learning from data directly. This is done by statistical models or algorithms such as neural networks. After training, the system needs to be able to generalize what it learned to previously unseen data.

The rapidly expanding discipline of data science overlaps with machine learning. It focuses on understanding the data and its inherent relationships. Those insights can then be used in the design of systems and applications or by experts directly or indirectly to improve machine learning-based systems.

Artificial intelligence is an umbrella term that covers data science, machine learning, and statistics. It also covers heuristic approaches that exhibit “intelligent” behavior. One biologically inspired heuristic would be the ant colony optimization algorithm.


Machine Learning Applications and Proteomics Analysis

Machine learning has been helpful in many disciplines, such as the life sciences and computational biology, specifically. Mass spectrometry is a standard high-throughput analytical technique for the characterization of biomolecules, such as proteins. The size of data generated in mass spectrometry-based protein analysis (proteomics) is so vast that it cannot be analyzed without computational analysis.

For many years, heuristic algorithms were used for computational analysis, but recently machine learning-based systems have shown large improvements in the number of identified proteins in mass spectrometry-based data and reduced the error rates substantially. [1]

Machine learning is quickly gaining popularity in the field because MS-based proteomics has no shortage of hard challenges and because publicly available data are becoming available in ever-increasing numbers.

Artificial Intelligence at MSAID

As the pioneer in proteomics AI, MSAID replaces outdated algorithms with potent AI-based solutions and paves the way for a more thorough and trustworthy method of querying proteomics data. We use all branches of artificial intelligence to improve the computational analysis of mass spectrometry-based data, whichever fits its purpose best. We facilitate the use of artificial intelligence in the field of proteomics by making our software and services simple to use and easily accessible.

For example, we create deep learning models to predict peptide properties for bottom-up proteomics and incorporate them into creative software solutions, powered by enormous volumes of training data.
