Answered 2022-Mar-18 at 16:47You should be using tf.keras.Sequential()
or tf.keras.models.Sequential()
. Also, you need to define a valid loss function. Here is a working example:
QUESTION
I recently coded a neural network based on this online book and Sebastian Lague's brief series on neural networks on youtube. I coded it as faithfully to the original as possible but it didn't end up working. I am trying to solve a simple XOR problem with it but it always seems to give me random but similar values. I even tried copying and pasting the author's code, without changing anything, but it still didn't work.
...ANSWER
Answered 2021-Apr-17 at 18:12I seem to have fixed it. I made three main changes:
I switched the a and o in the output layer error calculation which then looked like this:
error = (o - a) * self.activationPrime( self.zCollection[-1] )
.When updating the weights and biases I replaced
QUESTION
I am trying to define a function which gets some natural number n
as input. Depending on this input the function should have different constraints. This constraints get calculate with a type family. The number has to be converted to GHC.TypeNats
because the constraints are for Data.Vector.Sized
. I asked a similar question here, but the answer won't work in the case of GHC.TypeNats
and arbitrary n
.
I tried the UNat
type from Clash.
This is the relevant code from clash:
...ANSWER
Answered 2020-Dec-08 at 08:19I solved this by adding the constraints to the construtors of the GADT Peano nat.

QUESTION
I saw that TF Lite has a delegate that uses NNAPI for hardware acceleration. I was reading up on NNAPI and I saw that it has a compilation setting called ANEURALNETWORKS_PREFER_LOW_POWER
, which compiles a given NNAPI model to prioritize low power consumption. Does TF Lite have a setting that utilizes this, or any, power-saving mode? I'm developing for mobile using TF Lite for Android on Android Studio.
ANSWER
Answered 2020-Jul-01 at 23:25You can use the low-power option on the NNAPI delegate by setting this option while creating the delegate as mentioned in the documentation.
QUESTION
I was working on a project where I was training a neural network and displaying information using a GUI in Python. However, I have a constant problem with importing modules. This is the error I get when trying to run Visualizer.Main
...ANSWER
Answered 2020-Jun-05 at 09:51You seem to have a cyclic dependency between Visualizer.Utils
and NeuralNetworks.Pose`:
from Visualizer.Utils import loadImage
File "/home/user/SplineTrajectoryGenerator/Visualizer/Utils.py", line 3, in
from NeuralNetworks.Pose import Pose2D
File "/home/user/SplineTrajectoryGenerator/NeuralNetworks/Pose.py", line 4, in
from Visualizer.Utils import constraint
Python does not support cyclic dependencies - and that's actually a GoodThing(tm) since those are design issues (two modules should not depend on each other). The canonical solution is to create a new module for objects (classes, functions, whatever) that are necessary to both modules (ie in your case create a distinct module for 'constraint').
