kandi X-RAY | neural-net Summary
Classifying the images from our dataset can be done with a relatively small, easily understood network. We're just going to use two densly connected layers. In Keras, the network can be defined as... The input is a 28x28 matrix that'll get flatted into a 784 element vector. The first dense network will consist of 128 neurons, each connected to every element in the input vector. The second dense layer will be the head of the network. It outputs 10 elements, one for each class present in the dataset. The math behind this is very simple. The flatten layer has no math at all. The dense layers each output activation(weights * input + bias). The RELU activation function is just max(0, input). It introduces non-linearity to the network, which is important for image recognition. The softmax function is just exp(input)/sum(exp(input)). It normalizes our outputs into a probability vector. If you have optimized weights and biases, generating the predictions for an input image is basic math. The entire trick to machine learning is in figuring out the right weights and biases. And in this network, there are 101,632 weights and 138 biases to optimize. See the Tensorflow equivalent here if you want to confirm that this network design does actually work and see what the output looks like.

requires a tuple. (T,)
is a Python way to pass one-element tuple.
QUESTION
I am trying to implement Neural Network from scratch. By default, it works as i expected, however, now i am trying to add L2 regularization to my model. To do so, I need to change three methods-
cost() #which calculate cost, cost_derivative , backward_prop # propagate networt backward
You can see below that, I have L2_regularization = None
as an input to the init function

I'm trying to study the neural-network-and-deep-learning (http://neuralnetworksanddeeplearning.com/chap1.html). Using the updated version for Python 3 by MichalDanielDobrzanski (https://github.com/MichalDanielDobrzanski/DeepLearningPython). Tried to run it in my command console and it gives an error below. I've tried uninstalling and reinstalling setuptools, theano, and numpy but none have worked thus far. Any help is very appreciated!!
Here's the full error log:

I am new to PyTorch and Machine Learning so I try to follow the tutorial from here: https://medium.com/@nutanbhogendrasharma/pytorch-convolutional-neural-network-with-mnist-dataset-4e8a4265e118
By copying the code step by step I got the following error for no reason. I tried the program on another computer and it gives syntax error. However, my IDE didn't warn my anything about syntax. I am really confused how I can fix the issue. Any help is appreciated.
...ANSWER
Answered 2022-Feb-25 at 06:42If you are working on jupyter notebook. The problem is more likely to be num_worker
. You should set num_worker=0
. You can find here some solutions to follow. Because unfortunately, jupyter notebook has some issues with running multiprocessing.

QUESTION
I am trying to create an NLP neural-network using the following code:
imports:
...ANSWER
Answered 2022-Feb-13 at 11:58The TextVectorization
layer is a preprocessing layer that needs to be instantiated before being called. Also as the docs explain:
The vocabulary for the layer must be either supplied on construction or learned via adapt().
Another important information can be found here:
Crucially, these layers are non-trainable. Their state is not set during training; it must be set before training, either by initializing them from a precomputed constant, or by "adapting" them on data
Furthermore, it is important to note, that the TextVectorization
layer uses an underlying StringLookup
layer that also needs to be initialized beforehand. Otherwise, you will get the FailedPreconditionError: Table not initialized
as you posted.
QUESTION
I'm trying to figure out how to use the request
function of the http
and https
built-in modules in Node JS (I am aware of third-party wrappers but I'm trying to figure it out myself). I'm running into an issue where the Buffer data from the Response is partially cut off at the end. The issue does not occur when testing with cURL
.
Here is the code I've been using:
...ANSWER
Answered 2022-Jan-21 at 21:16The buffer should only be processed when the end
event fires, otherwise you may be processing an incomplete buffer.
QUESTION
I'm trying to learn how keras.layers.SimpleRNN
works by following a relatively straightforward tutorial (https://machinelearningmastery.com/understanding-simple-recurrent-neural-networks-in-keras/). However, this tutorial assumes the input is scalar, and I've been unable to scale this to higher-dimensional inputs. Here is my attempt to reproduce the behaviour of a simple RNN with 1x2 input for 3 time steps:
ANSWER
Answered 2022-Jan-08 at 03:13The matrix multiplications are correct, but they need to be performed at every timestep. And if return_sequences=False
Keras returns the output of the last timestep of shape ( 1 , 4 )
. So, we can create a for-loop which can perform the matrix multiplications for 3 timesteps.
Note: The input shape
( 3 , 2 )
denotes( time_steps , num_features )
Here's the code to replicate the Keras RNN model,
