Basic Concept of Machine Learning and Its Applications in Drug Development

Drug development is a lengthy process, and it depends on various factors. With technology development, the machine learning approach can improve discovery and decision-making for well-defined criteria and high-quality data. The primary challenge while applying machine learning is the lack of interpretability and the risk of repeatability of ML-generated results. However, rapid speed is very much needed in the drug development process compared to the current approach with slow productivity. With a better technological approach with machine learning, we can fast-track the usual processing period. ML guides and helps learn a system to interfere and make decisions by itself without any outer help. The decisions are taken when the system picks up the pattern. With past experiences, it can improvise; it uses a primary data reference of learning from the data it had been provided and decodes the connected patterns present within it. Having an initial data set for primary comparison is crucial. Over time, with the newly acquired data, the system can find a pattern and base its decision upon it.

To have a better sense of operation, we need to dive in a little further to grasp the basic idea. ML tasks in a broader sense could be categorised in three parts:

ML algorithms are not exclusive to similar subsets of AI. Random Forest is a popularly used algorithm widely used for large datasets with various attributes. The underlying mathematical process of RF comprises several uncorrelated decision trees as an ensemble; each tree is responsible for determining into one prediction. Another approach is Naïve Bayesian; it is an algorithm that is a subset of the supervised learning method, which has become one of the most required tools in predictive classification. The effectiveness of NB along with decision tree algorithms for text mining usage is still not determined. These approaches enhance the accuracy of retrieved data sets, which generally originate in significant, muddled sources. The usage of ML-based mining has proved to be very successful with the arrival of high output data generation and collection. These algorithm approaches have been extensively used alongside the vast data generated utilizing high output sequencing to boost up the target discovery process.

The innovative approach of algorithm-assisted data collection and manipulation has already been implemented in upcoming research. Researchers succeeded in use of unsupervised learning techniques through Gene Cluster with identifying category of cell lines; one of which was a primary melanoma group, and the other was an aggressive melanoma group. ML-based techniques try to rejuvenate the drug development process. These processes are primarily based on separate applications in the target discovery method, lead compound discovery method, synthesis approach, protein-ligand interactions, etc. Machine Learning-based applications are initially laying the path for algorithm-increased data query, analysis also in generation. As an example, ML incorporated into target discovery, based mainly on the rectification and in search of present omics and medical data. With AI integration using ML techniques, viable targets can be found using data clustering, regression, and classification from vast omics databases and sources. Owing to more accurate algorithms, more efficient supercomputers, and profound private and public funding into the research and development field, these applications are becoming more intelligent, cost-effective, and time-efficient while boosting efficacy.
