Understanding the Workings of Machine Learning

November 27, 2023

Machine learning (ML) has evolved significantly from its early days of computers learning to recognise patterns in data. Today’s machine learning involves complex algorithms that process large data sets quickly and efficiently, giving businesses a competitive edge.

What is Machine Learning?

Machine learning is a subset of artificial intelligence (AI) that enables computers to mimic human learning, adapting and improving based on previous experiences. It autonomously examines data to discern patterns, with minimal human input. Machine learning can automate tasks traditionally performed by humans, such as customer service interactions, bookkeeping, or resume screening, by identifying repeatable patterns and making data-driven decisions.

Key Techniques in Machine Learning

Machine learning primarily employs two techniques:

Supervised Learning: This involves using a dataset, known as a training set, which has already been labelled or classified in some way. For instance, a set of data from train station readouts, along with information about past delays, can serve as a training set. The machine learns by comparing its output with the actual data in the training set, adjusting its algorithms accordingly. Supervised learning is akin to the way humans learn from experience.

Unsupervised Learning: This technique is used to uncover hidden patterns in unlabeled data. Unsupervised learning algorithms strive to understand the underlying structure of data without any predefined labels or categories. Two common applications are clustering and dimensionality reduction. Clustering involves grouping data points into distinct categories based on their similarities, which can be useful in market segmentation. Dimensionality reduction simplifies datasets by consolidating similar or related variables, facilitating easier analysis and more efficient model training.

Applications and Languages of Machine Learning

Machine learning (ML) finds diverse applications, ranging from simplifying routine data entry tasks to handling more intricate matters like insurance risk assessment and fraud detection. It enhances customer-facing services with personalised recommendations akin to Amazon’s product suggestions or Spotify’s playlist algorithms. Internally, it accelerates organisational processes and reduces manual labour.

One key aspect of machine learning is its capability to identify patterns that might escape human detection. ML models excel at recognising complex patterns, offering insights that might be missed in traditional human analysis.

Utilising cognitive technologies such as natural language processing, machine vision, and deep learning, machine learning alleviates the human workload, redirecting focus towards enhancing product innovation and service quality. While humans can identify patterns in well-structured data sets, machine learning algorithms can analyse much larger data pools more swiftly and accurately.

Preferred Programming Languages for Machine Learning

Among the various programming languages used in machine learning, R and Python are familiar to most data scientists. Python, in particular, stands out due to its extensive library support and versatility in implementing various ML models and algorithms. This has made it the most popular language for machine learning, as highlighted by its top ranking on GitHub’s list of machine learning languages.

Python is frequently employed in data mining and analysis, supporting a range of ML algorithms including classification, regression, clustering, and dimensionality reduction. While Python leads the way, other languages also play significant roles in machine learning. The choice of language often depends on the specific requirements of the ML model or project. Additionally, for machine learning applications that incorporate models written in different languages, tools like machine learning operations (MLOps) become invaluable.
