QUESTION
I need some help for a project I am working on for a data science course. In this project I classy the digits of the MNIST datasets in three ways:
- using the dissimilarity matrices induced by the distances 1,2 and infinity
- using a BallTree
- using a neural network.
The first two parts are done, but I getting an error for the neural network code that I can't solve. This is the code.

I have logistic regression with binary observations y (0,1) and two independent variables (x1 and x2). I want to visualize model predictions by heatmap (matrix of predicted values in 2D). I am able to partially get what I want (see plot below), but how to add:
- colour scale to predicted values
- appropriate axes (horizontal and vertical) for x1 and x2
- how do I know the appropriate rotation of matrix? Is x1 (or x2) on horizontal or vertical axis?

I'm pretty new to NumPy and I'm looking for a way to get the index of a current column I'm iterating over in a matrix.
...ANSWER
Answered 2019-Oct-06 at 19:13You don't need those functions and loops to do that. Those will not be efficient. When using numpy
, go for vectorized operations whenever is possible (in most cases it is possible). numpy broadcasting rules are used to perform mathematical operation between arrays of different dimensions, when possible, such that you can use vectorization, which is much more efficient than python loops.
In your case, say that your array arr
is:
QUESTION
I developed the application with gRPC servicer. The point of my application is:
gRPC servicer (class DexFxServicer in the code below) has Transmit method which is called by gRPC client outside.
Transmit method creates multiple channels and stubs for the different hosts from hostList.
Further application creates the process pool and launches it.
Each child process calls gRPC method SendHostListAndGetMetrics for its own stub and receives response iterator.
This code works well, the application invokes Transmit method and receive all needed results from the process pool. But I noticed when outside gRPC client calls Transmit method multiple times, this code didn't close some of its child processes. And it leads to extra nonclosing processes creation as htop shows. When I try to close gRPC channels by channel.close() method, extra processes are being created more intensively.

QUESTION
I have an idea to create a Container
class to use any container-like type universally:
ANSWER
Answered 2019-Jun-04 at 09:28Take a look at Control.Lens.At, and perhaps ask a more specific question after you've seen what's done there? Admittedly that's done with the slightly different goal of setting up lenses, but it amounts to much the same thing. I'll try to give a brief explanation of how it works though.
First, it's worth noting that what you want would be better seen as an associative mapping typeclass rather than a container, as you wish to be able to look up the value at a k
.
Thus, Control.Lens.At sets up two type families, Index
and IxValue
, for the key and value type of the container. For example, a Map k v
has Index (Map k v) = k
and IxValue (Map k v) = v
as you might expect (eliding that k
must be Ord
), whereas a list can be thought of as a mapping from indices to its values, thus Index [a] = Int
, IxValue [a] = a
.
These type families are used to construct the typeclass Ixed
saying, given a container :: c
and an k = Index c
then I can retrieve an v :: Maybe (IxValue c)
(depending on whether it's present or not) (and indeed modify at k
instead if desired). As I said earlier, this is done to set up lenses, but this approach could be adapted if desired.
You could also take a look at IsMap for another point in the design space. No language extensions used there either.
