QUESTION
ANSWER
Answered 2019-Nov-18 at 13:18Ok. Since you are going to have custom trainable weights, the way to do this in Keras is creating a custom layer.
Now, since your custom layer has no inputs, we will need a hack that will be explained later.
So, this is the layer definition for the custom weights:

QUESTION
I've encountered strange behavior when using AS3's TouchEvent
s to handle multi-touch. The touch lags considerably in certain situations, but Flash's frame rate isn't affected. It's as though the touches are getting buffered and the events just aren't dispatched until several seconds after the touch.
I've uploaded a demonstration here: https://youtu.be/omkCDqljfio
I've only managed to reproduce this touch lag in the ActiveX version of Flash Player, but I've reproduced it in both Windows 10 and Windows 7. So what I have here is a C# application that's hosting my AS3 test suite, but it can also be observed if the swf is viewed in Internet Explorer.
Since my application already involves hosting the SWF in a WPF window, I've been attempting to create a solution where touch is received in C# and then communicated to the AS3. It would work perfectly but it seems my WPF window isn't receiving touch frames when the touch is on a WindowsFormsHost
. So there's another problem that I have to solve.

Answered 2017-Jun-24 at 19:38Now that I've used Adobe Scout I think it is a rendering issue after all. The frame rate still shows 30fps because the processing time just barely manages to hit the 30fps mark. Lowering the frame rate fixes the problem.
It is still strange that the touch events would have such a long delay when the frame rate is just barely falling short, though.
QUESTION
Questions:
1) How is it that numpy.dot()
is slower than *
in the example code below when BLAS is being used?
2) Is there a way that numpy.dot()
can be implemented instead of *
in this case for faster array multiplication? I think that I am missing a piece of crucial information which would answer question 1 and mean that numpy.dot()
is at least as fast as *
, if not faster.
Details included below. Thanks in advance for answers and help.
Details:
I am writing a program which solves coupled PDEs using python 2.7 (64-bit), numpy 1.11.2, Anaconda2 on Windows 7. To improve the accuracy of the program output I need to use large arrays (shape (2, 2^14) and larger) and small integration steps, resulting in a gigantic number of array multiplication operations per simulation which I need to optimize for speed.
Having looked around, it seems as though numpy.dot()
should be used for faster array multiplication with respect to *
as long as BLAS is installed and working with numpy. This is frequently recommended. However, when I use the timer script below, *
is faster than numpy.dot()
by at least a factor of 7. In some cases this increases to factors >1000:
