A Guide to Machine Learning in Finance

Is machine learning the key to efficient financial operations? Machine learning applications can be used for everything from risk assessment to asset management, using data for critical insights and streamlining various processes while optimising results.

Using machine learning in financial applications is an evolving practice utilised in various ways throughout the industry. The diverse applications of machine learning in finance have also opened up many new machine learning finance jobs. But first, it helps to understand machine learning in finance and how it can be used to build a career. 

What exactly is machine learning in finance?

Machine learning belongs under the umbrella of artificial intelligence. It deals with designing and developing algorithms to learn from and make predictions based on data. Machine learning models provide the technology to automate cognitive tasks. Various financial tasks utilise machine learning technology, including credit scoring, investment monitoring and recommendations, fraud detection, and algorithmic trading. 

Machine learning can help financial companies make better pricing, risk, and customer behaviour decisions. The technology can build models that improve understanding of large data sets and uncover patterns that facilitate new business systems and processes.

Why finance companies are turning to machine learning and AI

Machine learning and artificial intelligence can speed up processes and improve raw data use. In turn, this can save time and money while improving business outcomes. Finance companies increasingly turn to machine learning and AI to automate repetitive tasks, provide better customer service and experiences, and gain an edge over competitors. 

Streamlining and process automation

Working in finance, the ability to streamline and automate various processes using machine learning has many benefits. Finance companies can use these technologies to automate tasks such as paperwork, calculations, data monitoring, and claims processing. This can free up employees to focus on more value-added activities.

Customer engagement and personalisation: The Internet of Things

Customer engagement is another critical area where machine learning and AI can be used. IoT devices can generate considerable data that helps understand customer behaviour and preferences [1]. The data can then be used to create personalised marketing campaigns or to improve customer service. Overall, better customer service and improved customer experiences typically lead to more sales and higher customer satisfaction rates.

Big data analysis for a competitive edge

Big data analysis has become essential for understanding customer behaviour and trends. Machine learning and AI can help you make sense of large data sets, identify patterns, and make predictions. This can help you gain a competitive edge by making better decisions faster than your competitors.

Machine learning use cases in banking

Each of the biggest banks in the United Kingdom—HSBC, Barclays, and Lloyds Banking Group—uses machine learning to improve operations. Machine learning detects and prevents fraud, better targets marketing efforts, and streames back-office processes. 

In addition, they are using machine learning to develop new financial products and services, such as predictive analytics tools, which can help their customers make better investment decisions.

Careers in machine learning in the finance sector

Machine learning is relatively new in finance and other industries, and a high demand for qualified workers exists. Machine learning jobs fall under employment categories like computer programming, software development, and financial analysis. The UK Government has recently invested millions of pounds into boosting AI jobs and training, anticipating a growing need for professionals trained in AI and machine learning skills. Businesses in the finance sector increasingly rely on data-driven decision-making. As the field of machine learning evolves, there will be new opportunities for those with machine learning expertise to apply their skills in the finance sector.
