Specialized Document Embeddings for Aspect-based Similarity of Research Papers
- Computer Science2022 ACM/IEEE Joint Conference on Digital Libraries (JCDL)
- 2022
The approach of aspect-based document embeddings mitigates potential risks arising from implicit biases by making them explicit and can, for example, be used for more diverse and explainable recommendations.

Financial Signal Processing and Machine Learning
- Computer Science
- 2016
This book focuses on signal processing approaches to model return, momentum, and mean reversion, addressing theoretical and implementation aspects and highlights the connections between portfolio theory, sparse learning and compressed sensing, sparse eigen-portfolios, robust optimization, non-Gaussian data-driven risk measures, graphical models, causal analysis through temporal-causal modeling, and large-scale copula-based approaches.

It is found that simply using LASSO is insufficient to lower turnover when the model’s tuning parameter can change over time, and it is possible to maintain the low-risk profile of efficient estimation methods while automatically selecting only a subset of assets and further inducing low portfolio turnover.
Clustering Stock Data for Multi-objective portfolio Optimization
