Curious what your thoughts on this are: <a href="http:&#x2F;&#x2F;globalslant.com&#x2F;2015&#x2F;06&#x2F;black-box-trading-why-they-all-blow-up&#x2F;" rel="nofollow">http:&#x2F;&#x2F;globalslant.com&#x2F;2015&#x2F;06&#x2F;black-box-trading-why-they-al...</a><p>TLDR: Essentially black box trading inevitably fails because they&#x27;re all trying to do the same thing. At a certain point everyone tries to liquidate, or buy, or perform same trades at the same time which can lead to a blow up.<p>I wonder if getting around this assumes some sort of diversity in algorithms&#x2F;ML approach, and if that diversity is a realistic assumption

Can someone put in layman&#x27;s terms the passage below? please. Assuming the reader has some machine learning experience but no financial knowledge. Thanks<p>#### numerai_training_data.csv Use this dataset to train your machine learning algorithm. The first fourteen columns (`f1` - `f14`) are integer features. Column `c1` is a categorical feature, column validation indicates a dataset that you can use to validate your model, and target is the binary class you’re trying to predict.

Perfect timing as I&#x27;m about to start putting some time and resources into researching some good stocks and investments.

It&#x27;s not exactly in the spirit of data science when the features are unknown and every integer is sort of a black box. Any insights?

What is the advantage of an order preserving encryption scheme over choosing an arbitrary mapping for each data column and applying that to the data?
