Several algorithmic common sense you have to know in machine learning

We already know that we want to have a generalization ability of models learned through machine learning. In a straightforward way, it is that the learned model not only works well in the training samples, but also works in new samples well.

Large Data processing interview problem summary

1. Given a, b two files, each store 5 billion URLs, each URL accounted for 64 bytes, memory limit is 4G, let you find a, b file common URL? Scenario 1: The size of each file can be estimated to be 50gx64=320g, far larger than the memory limit of 4G. So it is not possible to fully load it into memory processing.   Consider adopting a divide-and-conquer approach. s traverses file A, asks for each URL, and then stores the URL to 1000 small files (recorded) based on the values obtained. This ...

The physics that the start-up company survived

Absrtact: A living organism is constantly generating entropy or increasing positive entropy, and gradually approaching the dangerous state of maximum entropy, i.e. death. To get rid of death, to live, the only way is to constantly draw negative entropy from the environment. A living organism has the risk of delaying "a living organism constantly generating entropy--or increasing the positive entropy, and gradually approaching the maximum entropy of a dangerous state, that is, death." To get rid of death, to live, the only way is to constantly draw negative entropy from the environment. A living organism has the odd tendency to defer to thermodynamic equilibrium (death).
