clipping

Go back to the [[AI Glossary]]

A technique for handling outliers. Specifically, reducing feature values that are greater than a set maximum value down to that maximum value. Also, increasing feature values that are less than a specific minimum value up to that minimum value.

For example, suppose that only a few feature values fall outside the range 40–60. In this case, you could do the following:

Clip all values over 60 to be exactly 60.
Clip all values under 40 to be exactly 40.

In addition to bringing input values within a designated range, clipping can also used to force gradient values within a designated range during training.

“The restaurants are open in South Korea. You can go shopping in Taiwan. Offices are open in Singapore,” Hunt wrote. “These countries learned the hard way how to deal with a pandemic after the deadly Sars virus. They now show us how we can emerge from lockdown.”

Germany has carried out four times as many tests as the UK and recorded only 342 deaths from the virus. “Where you find it, you can isolate and contain it,” Hunt wrote.

There are currently 8,000 available and another 8,000 said to be arriving in the next few weeks. Stefan Dräger, the head of ventilator manufacturer Drägerwerk, told German magazine Der Spiegel that the number of intensive care beds in England per capita was lower than Italy and five times lower than in Germany. “The challenge in England will be greater than in Spain,” he warned.
