Binary is a base 2 number system. Base 2 means there are only two digits---1 and 0---which correspond to the on and off states your computer can understand. You're probably familiar with base 10---the decimal system. Decimal makes use of ten digits that range from 0 to 9, and th...
Complex causal queries, such as attributing observed anomalies to nodes in the system, can be performed with just a few lines of code: importnetworkxasnx,numpyasnp,pandasaspdfromdowhyimportgcm# Let's generate some "normal" data we assume we're given from our problem domain:X=np.random.norm...

use string instead. In the cosmic scale of things, it doesn't much matter which you choose. One string, list, or bag class is pretty much like another. However, there are times when one or another system works better. For example, in my RECYCLE program from the previous question, I u...
access to fewer resources, making them more efficient and easier to deploy in large scale projects. additionally, compiling can lead to better debugging as errors tend to be caught earlier in the process due to the nature of compiling being closer to machine code. why do developers use compile...
In the digital universe that exists inside of our computers, everything must begin with the bit, enough room to store a single unit of data. This means computers must use a base-2 number system, also known as binary. Counting up, after the number one, we flip to zero with a “1” ...
Text.Image to System.Drawing.Bitmap? Can I do a Visual Basic (VB) Stop in C#? Can I have mutiple app.config files? Can I have two methods with the same name and same number of parameters like Ruby? can I query a struct (or class) to get a list of it's attributes and data ...
Finally, to turn this maximization problem into a minimization problem that lets us use stochastic gradient descent optimizers in PyTorch, we are interested in the negative log likelihood: L(w)=−l(w)=−∑i=1n[y(i)log(σ(z(i)))+(1−y(i))log(1−σ(z(i)))].L(w)=−l(...
drive, for use by your computer. this typically involves creating a file system and partitioning the disk into sections that can be used to store data. what is a partition? a partition is a section of a hard drive or other storage device that is treated as a separate entity by your ...
these tools are only as powerful as the amount of work that you put in at the start. We sometimes face a similar problem with language compilers. Although compilers usually succeed at turning the developer’s code into a smaller and faster binary, they have been known to fail badly on occa...
