Applications like robo-advisors, algorithmic trading, and personalized banking are redefining customer experiences. Additionally, AI-driven regulatory compliance and anti-money laundering efforts are enhancing security.

so dump your predictors in a net with a huge hidden layer and feed the final layer through a ridge regression?

This was a great lecture with very surprising results. I had always assumed that overfit large models would always be worse to use since the training data was finite. Never thought the opposite was the case. Great work.

@@brhnkh From what I understand from the lecture, one of the key insights is that larger models should be able to perform better out of sample. The general problem with using ML for time series data is that they are easy to overfit due to the limited training set and feature representation. However with a diverse feature set, larger models should be able to generalize better which is intuitive to me.The reason why many experts would recommend against bigger models is because they are much easier to overfit to the training data but this may just because they were training with a small feature set that did not have many predictive outcomes. Whenever this is the case, a model will learn the dataset itself in order to achieve the reward without finding patterns that can be repeated in out of sample data.

@@Khari99 Right. The last sentence is what's novel I think. The model gets better at out-of-sample data because it is appropriately penalized while being trained with very large number of parameters. Apparently, they figured it out using random matrix theory, so the heavy lifting lies there I guess.

@@brhnkh the reward function is always the most difficult part of ML. It took me a while to figure out how to write mine for my architecture. Simply using max profit is not enough (a model could learn to buy and hold forever for instance) And neither is accuracy. (high accuracy != profitability). You have to reward it and penalize it in a similar way that you would a human based on metrics its able to achieve on a trade by trade and portfolio basis.

@@brhnkh I thought a definition of overfitting was when validation error starts to increase rapidly, after reaching its minimum during training, whilst training error continues to decrease. It is therefore not clear to me, why you would want a model to overfit at all, finance or not. I'm only 4 minutes into the video, perhaps he will explain it.

Some notes Interconnectedness of crises Rich literature on banking crises - but there’s systematic relationship between banking and currency crises Banking crises typically came after financial liberalization 125 countries, 300 banking crises = tight connection between capital market integration (open capital account) and incidences of banking crises In era of heavy regulation, relative dearth of financial crises Before, currency and banking crises were looked at in isolation But, banking crises often lead to future currency problems - feedback loops A legacy of banking crises is that governments end up with a lot of debt - takes over private debts / bank debts Banking crisis increases probability of sovereign debt crisis - but not other way around Pattern of steps -Financial liberalization -Boom in economic activity, asset prices -Slowdown / onset of banking problems -Bank crisis -Sovereign debt crisis How to engage severity of crisis - look at per/capita GDP, and number of years required to return to pre-crisis peak Most severe 100 crises, ranked - lots of triple crises (bank, currency, sovereign debt) Antecedents of financial crises -currency overvaluation - bad loans, firm over-profitability -asset price bubbles -credit boom -build up of short-term debt -decline of bank deposits / existence of bank runs -hidden debts - all kinds of nasty surprises are revealed during crises - Post crises recessions are longer and more protracted than norm Even by 2018, countries like Italy and Greece still had not returned to pre-crisis peaks (re: 2008 financial crisis) Legacy of these crises is build-up of public sector debt Advanced economies are no strangers to sovereign default

Thanks for putting the conference recordings online, very interesting keynotes and discussion panels. What I am puzzling about though is the remark by Rahmouni-Rousseau at the 1:14:18 time mark kzfaq.info/get/bejne/qLlkZ6yUx92XYYk.html about minimum reserve requirements for commercial banks in the Euroarea. She said: "there is no strict regulatory requirement for Euroarea banks to hold reserves; the requirement is on HQLA" and banks just prefer to hold reserves instead of hqla's. Does that mean legally there are no minimum reserve requirements?

I am sorry but this is just a typical Swedish meeting, ”I agree”, “good point”, “more can be done” etc. We should instead focus on what you have done and what can be done. Why aren’t we measuring nationality? Anonymous applications will just favor typical Swedes since they already have an head start that will show up in the CV indirectly (via networks, societies, previous experience etc). One possible solution could be to implement a quota on nationality, gender, background etc.
