Machine Learning with Pascal II

Also in Blaise Pascal Magazine Machine Learning with CAI:

A Machine Learning model cannot take this into account because errors for it have symmetrical costs, rarely in real life do we have equal costs for type I error and type II error, and whenever the costs are different, we need to choose the right threshold.

Statistically speaking, we want that our sample keeps the probability distribution of the population under a reasonable significance level. In other words, if we take a look at the histogram of the sample, it must be the same as the histogram of the population.

The portable pixmap format(PPM), the portable graymap format(PGM)
and portable bitmap format(PBM) are image file formats designed to
be easily exchanged between platforms. They are also sometimes
referred collectively as the portable anymap format(PNM). These
formats are a convenient (simple) method of saving image data.
And the format is not even limited to graphics, its definition
allowing it to be used for arbitrary three-dimensional matrices or
cubes of unsigned integers.

2. Select Advanced settings and highlight Inbound Rules in the left pane.
3. Right click Inbound Rules and select New Rule.
4. Add the port you need to open and click Next.
5. Add the protocol(TCP or UDP) and port number into the next window and click Next.
6. Select Allow the connection in the next window and hit Next.
7. Select the network type as you see fit and click Next.
8. Name the rule something meaningful and click Finish.
