What is the purpose of Looper and how to use it?
...in the context of GUI framework. Looper is made to do 2 things.
1) Looper transforms a normal thread, which terminates when its run() method return, into something run continuously until Android app is running, which is needed in GUI framework (Technically, it still terminates when run() method ret...
What is the difference between supervised learning and unsupervised learning? [closed]
...nsidered. The main characteristics of Self-Organizing Maps (SOM) are:
It transforms an incoming signal pattern of arbitrary dimension into
one or 2 dimensional map and perform this transformation adaptively
The network represents feedforward structure with a single
computational layer consisting o...
What exactly is metaprogramming?
...ams but, again, they are a subset of all metaprograms. The Fastest Fourier Transform in the West (FFTW) library is an example of such a metaprogram. The source code is written mostly in OCaml and it generates bits of C code (called codelets) that are combined to create high performance Fast Fourier ...
What's the advantage of Logic-less template (such as mustache)?
...lication flow. Instead what you should do is create a presenter class that transforms your model into a view model which is then consumed by the view. A view model is a model for the UI which is separate from the model which is part of the business logic. I recommend you to watch the "Clean Architec...
How do I call one constructor from another in Java?
...
I would agree that a very complex transformation likely indicates a design issue. But 1) there are some simple transformations which for which this may be useful - not all constructors are just linear projection on others and 2) there may be other situation w...
ggplot with 2 y axes on each side and different scales
...lot2 because I believe plots with separate y scales (not y-scales that are transformations of each other) are fundamentally flawed. Some problems:
The are not invertible: given a point on the plot space, you can not uniquely map it back to a point in the data space.
They are relatively hard to re...

Task not serializable: java.io.NotSerializableException when calling function outside closure only o
...a local one.
Not to get into too many details, but when you run different transformations on a RDD (map, flatMap, filter and others), your transformation code (closure) is:
serialized on the driver node,
shipped to the appropriate nodes in the cluster,
deserialized,
and finally executed on the no...
What is the use of Enumerable.Zip extension method in Linq?
... by one, into a single new sequence. So you take an element of sequence A, transform it with the corresponding element from sequence B, and the result forms an element of sequence C.
One way to think about it is that it's similar to Select, except instead of transforming items from a single collect...
