Machine Learning for Quantitative Finance Applications: A Survey

Abstract

The analysis of financial data represents a challenge that researchers had to deal with. The rethinking of the basis of financial markets has led to an urgent demand for developing innovative models to understand financial assets. In the past few decades, researchers have proposed several systems based on traditional approaches, such as autoregressive integrated moving average (ARIMA) and the exponential smoothing model, in order to devise an accurate data representation. Despite their efficacy, the existing works face some drawbacks due to poor performance when managing a large amount of data with intrinsic complexity, high dimensionality and casual dynamicity. Furthermore, these approaches are not suitable for understanding hidden relationships (dependencies) between data. This paper proposes a review of some of the most significant works providing an exhaustive overview of recent machine learning (ML) techniques in the field of quantitative finance showing that these methods outperform traditional approaches. Finally, the paper also presents comparative studies about the effectiveness of several ML-based systems.

Modeling US Dollar and Nigerian Naira Exchange Rates During COVID-19 Pandemic Period: Identification of a High-performance Model for New Applications

“…This open access article is distributed under a Creative Commons Attribution (CC-BY) 4.0 license before application and the results obtained justified their use in modeling of USD to NGN exchange rates. The ARIMA model is a classical statistical method, whereas ANN and RF are machine learning models (Rundo et al, 2019). Machine learning is a part of artificial intelligence that enables information technology systems to recognize patterns based on existing algorithms and data sets and use the same to develop sustainable solution concepts.…”

Legaltech and Lawtech: Global Perspectives, Challenges, and Opportunities

“…Other authors consider that Legaltech would be the appropriate term as it describes the activities of the legal sector, as does RegTech, the technology that helps to comply with regulation, for example helping to reduce the large amount of time and high costs that banks spend on regulatory compliance (Butler and O'Brien 2019), InsurTech as technologically-based insurance service (Gramegna and Giudici 2020), or FinTech as finance and technology to accelerate the digitalization of both the financial and insurance sectors (Rundo et al 2019). Wealthtech can also be considered a subcategory of Fintech, given that its objective is to manage and grow people's financial wealth through technological advances (Chishti and Puschmann 2018).…”

Know Your Clients' Behaviours: A Cluster Analysis of Financial Transactions

“…Machine learning algorithms have been widely used in financial applications, such as risk modelling, return forecasting, and portfolio construction (Emerson et al 2019), quantitative finance (Rundo et al 2019), financial distress prediction (Huang and Yen 2019), banking risk management (Leo et al 2019), credit-scoring models and financial crisis prediction (Lin et al 2011), automation through artificial intelligence Donepudi 2019, market prediction (Henrique et al 2019), and credit risk modeling, detection of credit card fraud and money laundering, and surveillance of conduct breaches at financial institutions (Van Liebergen 2017). Popular algorithms used in these applications are support vector machines (Kim 2003), neural networks (West et al 2005), and random forests (Patel et al 2015).…”
