Quantitative Methods and Machine Learning: Jan 2021

NLP, Machine Learning, and Quant – Top Recent Papers

Nowadays, many discussions of quantitative methods revolve around factor investing, but quant can also take on a variety of other forms. Machine learning (ML) techniques are increasingly being used to enhance financial models, finding new statistically significant variables that would likely go undetected by the human eye.

State Street looks at how we can validate the output from ML-enhanced models as both trustworthy and applicable. McKinsey & Company explains the basic premises of quantum computing and the beneficial characteristics of qubits for investment managers of the future. Meanwhile, investment managers of the present who are at all curious about the formulas that constitute index mathematics should turn their gaze to the second paper on the below list from S&P Dow Jones Indices.
