A Hypothesis on Good Practices for AI-based Systems for Financial Time Series Forecasting: Towards Domain-Driven XAI Methods

no code implementations13 Nov 2023 Branka Hadji Misheva, Joerg Osterrieder

In this context, this paper explores good practices for deploying explainability in AI-based systems for finance, emphasising the importance of data quality, audience-specific methods, consideration of data properties, and the stability of explanations.

The Great Deception: A Comprehensive Study of Execution Strategies in Corporate Share Buy-Backs

no code implementations18 Jul 2023 Michael Seigne, Joerg Osterrieder

This lack of research into the execution phase is surprising, especially when compared to the extensive literature on other capital allocation decisions, such as acquisition pricing.

Feature Selection via the Intervened Interpolative Decomposition and its Application in Diversifying Quantitative Strategies

no code implementations29 Sep 2022 Jun Lu, Joerg Osterrieder

In this paper, we propose a probabilistic model for computing an interpolative decomposition (ID) in which each column of the observed matrix has its own priority or importance, so that the end result of the decomposition finds a set of features that are representative of the entire set of features, and the selected features also have higher priority than others.

AI for trading strategies

no code implementations26 Jun 2022 Danijel Jevtic, Romain Deleze, Joerg Osterrieder

In this bachelor thesis, we show how four different machine learning methods (Long Short-Term Memory, Random Forest, Support Vector Machine Regression, and k-Nearest Neighbor) perform compared to already successfully applied trading strategies such as Cross Signal Trading and a conventional statistical time series model ARMA-GARCH.

The Efficient Market Hypothesis for Bitcoin in the context of neural networks

no code implementations25 Jun 2022 Mike Kraehenbuehl, Joerg Osterrieder

This study examines the weak form of the efficient market hypothesis for Bitcoin using a feedforward neural network.

Deep reinforcement learning on a multi-asset environment for trading

no code implementations15 Jun 2021 Ali Hirsa, Joerg Osterrieder, Branka Hadji-Misheva, Jan-Alexander Posth

Our trading strategy is trained and tested both on real and simulated price series and we compare the results with an index benchmark.

Generative Adversarial Networks in finance: an overview

no code implementations11 Jun 2021 Florian Eckerli, Joerg Osterrieder

Modelling in finance is a challenging task: the data often has complex statistical properties and its inner workings are largely unknown.

The VIX index under scrutiny of machine learning techniques and neural networks

no code implementations3 Feb 2021 Ali Hirsa, Joerg Osterrieder, Branka Hadji Misheva, Wenxin Cao, Yiwen Fu, Hanze Sun, Kin Wai Wong

Using subset selection approaches on top of the original CBOE methodology, as well as building machine learning and neural network models including Random Forests, Support Vector Machines, feed-forward neural networks, and long short-term memory (LSTM) models, we will show that a small number of options is sufficient to replicate the VIX index.
