QUESTION
I writing my code within a Jupyter notebook in VS Code. I am hoping to play some of the audio within my data set. However, when I execute the cell, the console reports no errors, produces the widget, but the widget displays 0:00 / 0:00 (see below), indicating there is no sound to play.
Below, I have listed two ways to reproduce the error.
- I have acquired data from the hub data store. Looking specifically at the spoken MNIST data set, I cannot get the data from the
audio
tensor to play

Answered 2022-Mar-15 at 00:07Apologies for the late reply! In the future, please tag the questions with activeloop so it's easier to sort through (or hit us up directly in community slack -> slack.activeloop.ai).
Regarding the Free Spoken Digit Dataset, I managed to track the error with your usage of activeloop hub and audio display.
adding [:,0] to 9th line will help fixing display on Colab as Audio expects one-dimensional data

QUESTION
I'm trying to implement a gradient-free optimizer function to train convolutional neural networks with Julia using Flux.jl. The reference paper is this: https://arxiv.org/abs/2005.05955. This paper proposes RSO, a gradient-free optimization algorithm updates single weight at a time on a sampling bases. The pseudocode of this algorithm is depicted in the picture below.
I'm using MNIST dataset.
...ANSWER
Answered 2022-Jan-14 at 23:47Based on the paper you shared, it looks like you need to change the weight arrays per each output neuron per each layer. Unfortunately, this means that the implementation of your optimization routine is going to depend on the layer type, since an "output neuron" for a convolution layer is quite different than a fully-connected layer. In other words, just looping over Flux.params(model)
is not going to be sufficient, since this is just a set of all the weight arrays in the model and each weight array is treated differently depending on which layer it comes from.
Fortunately, Julia's multiple dispatch does make this easier to write if you use separate functions instead of a giant loop. I'll summarize the algorithm using the pseudo-code below:

Answered 2022-Jan-15 at 02:45when you use cmap="gray"
in plt.imshow()
you must either unscale your output or set vmin and vmax.
From what I see you scaled by dividing 255, so you must multiply your data by 255 or, alternativle set vmin=0, vmax=1

I'm working on Convolution Tasnet, model size I made is about 5.05 million variables.
I want to train this using custom training loops, and the problem is,
...ANSWER
Answered 2022-Jan-07 at 11:08Gradient tape triggers automatic differentiation which requires tracking gradients on all your weights and activations. Autodiff requires multiple more memory. This is normal. You'll have to manually tune your batch size until you find one that works, then tune your LR. Usually, the tune just means guess & check or grid search. (I am working on a product to do all of that for you but I'm not here to plug it).

QUESTION
I have created a working CNN model in Keras/Tensorflow, and have successfully used the CIFAR-10 & MNIST datasets to test this model. The functioning code as seen below:
...ANSWER
Answered 2021-Dec-16 at 10:18If the hyperspectral dataset is given to you as a large image with many channels, I suppose that the classification of each pixel should depend on the pixels around it (otherwise I would not format the data as an image, i.e. without grid structure). Given this assumption, breaking up the input picture into 1x1 parts is not a good idea as you are loosing the grid structure.
I further suppose that the order of the channels is arbitrary, which implies that convolution over the channels is probably not meaningful (which you however did not plan to do anyways).
Instead of reformatting the data the way you did, you may want to create a model that takes an image as input and also outputs an "image" containing the classifications for each pixel. I.e. if you have 10 classes and take a (145, 145, 200) image as input, your model would output a (145, 145, 10) image. In that architecture you would not have any fully-connected layers. Your output layer would also be a convolutional layer.
That however means that you will not be able to keep your current architecture. That is because the tasks for MNIST/CIFAR10 and your hyperspectral dataset are not the same. For MNIST/CIFAR10 you want to classify an image in it's entirety, while for the other dataset you want to assign a class to each pixel (while most likely also using the pixels around each pixel).
Some further ideas:
- If you want to turn the pixel classification task on the hyperspectral dataset into a classification task for an entire image, maybe you can reformulate that task as "classifying a hyperspectral image as the class of it's center (or top-left, or bottom-right, or (21th, 104th), or whatever) pixel". To obtain the data from your single hyperspectral image, for each pixel, I would shift the image such that the target pixel is at the desired location (e.g. the center). All pixels that "fall off" the border could be inserted at the other side of the image.
- If you want to stick with a pixel classification task but need more data, maybe split up the single hyperspectral image you have into many smaller images (e.g. 10x10x200). You may even want to use images of many different sizes. If you model only has convolution and pooling layers and you make sure to maintain the sizes of the image, that should work out.

QUESTION
I am trying to run a TensorFlow-lite model on my App on a smartphone. First, I trained the model with numerical data using LSTM and build the model layer using TensorFlow.Keras. I used TensorFlow V2.x and saved the trained model on a server. After that, the model is downloaded to the internal memory of the smartphone by the App and loaded to the interpreter using "MappedByteBuffer". Until here everything is working correctly.
The problem is in the interpreter can not read and run the model. I also added the required dependencies on the build.gradle.
The conversion code to tflite model in python:

Answered 2021-Nov-24 at 00:05Referring to one of the most recent TfLite android app examples might help: Model Personalization App. This demo app uses transfer learning model instead of LSTM, but the overall workflow should be similar.

Install MNIST
First, define environment values used in distributed MNIST learning.
$ export WORKER_NUMBER=3 $ export EPOCH=2 $ export BATCH=100 $WORKER_NUMBER : The number of workers in distributed learning. If it is set to 3, splitter will split MNIST dataset into 3 files, and the 3 trainers will be spawn in each Kubernetes node as a container. $EPOCH : // TODO $BATCH : // TODO
Create NFS container to store datasets and models. It will be used as a PV, PVC in Kubernetes. 1-nfs-deployment.yaml creates NFS server container to be mounted to other components, such as splitter, trainer. $ kubectl apply -f 1-nfs-deployment.yaml $ kubectl apply -f 2-nfs-service.yaml Create PV and PVC using NFS container. $ export NFS_CLUSTER_IP=$(kubectl get svc/nfs-server -o jsonpath='{.spec.clusterIP}') $ cat 3-nfs-pv-pvc.yaml | sed "s/{{NFS_CLUSTER_IP}}/$NFS_CLUSTER_IP/g" | kubectl apply -f - [Optional (but recommended) ] If you want to view directory of NFS server, create busybox deployment and enter into container. By default, index.html and lost+found files exist. $ kubectl apply -f 9999-busybox.yaml $ kubectl exec -it $(kubectl get pods | grep busybox | awk '{print $1}') sh / # ls /mnt index.html lost+found / # exit
Split MNIST dataset using splitter. Splitter will create datasets, the number of $(WORKER_NUMBER) $ cat 4-splitter.yaml | sed "s/{{WORKER_NUMBER}}/$WORKER_NUMBER/g" | kubectl apply -f - To check datasets are created, check in busybox deployment. Splitted datasets exist as *.npz $ kubectl exec $(kubectl get pods | grep busybox | awk '{print $1}') ls /mnt/data 0.npz 1.npz 2.npz
Train each dataset in Kubernetes workers. Below bash commands create trainers as deployment to train and extract neural network model. $ for (( c=0; c<=($WORKER_NUMBER)-1; c++ )) do echo $(date) [INFO] "$c"th Creating th trainer in kubernetes.. cat 5-trainer.yaml | sed "s/{{EPOCH}}/$EPOCH/g; s/{{BATCH}}/$BATCH/g; s/{{INCREMENTAL_NUMBER}}/$c/g;" | kubectl apply -f - & done After about 3 minitues, you can view the status of trainer job. Status should be completed. $ kubectl get po NAME READY STATUS RESTARTS AGE mnist-splitter-qgkxf 0/1 Completed 0 14m mnist-trainer-0-g896k 0/1 Completed 0 3m mnist-trainer-1-6xfkg 0/1 Completed 0 3m mnist-trainer-2-ppnsc 0/1 Completed 0 3m Also you can check generated models using busybox deployment. $ kubectl exec $(kubectl get pods | grep busybox | awk '{print $1}') ls /mnt/model 0-model.h5 1-model.h5 2-model.h5
Aggregate generated models into one model. Below command creates aggregator, which aggregate models into single model. $ kubectl apply -f 6-aggregator.yaml Check a aggregated model. $ kubectl exec $(kubectl get pods | grep busybox | awk '{print $1}') ls /mnt aggregated-model.h5 ... If you want to test accuracy of aggregated model, use 9999-accuracy-test deployment. $ kubectl apply -f 9999-accuracy-test.yaml $ kubectl logs --tail 1 $(kubectl get pods | grep accuracy-test | awk '{print $1}') 10000/10000 [==============================] - 10s 997us/sample - loss: 1.2667 - acc: 0.8728
Create server deployment for demo. You can test MNIST prediction. $ kubectl apply -f 7-server.yaml After a few seconds, you can see the external IP to access the demo web page. Below example shows external IP is a.b.c.d, so you can access a.b.c.d:80 in web browser $ kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE ... mnist-server-svc LoadBalancer 10.19.253.70 a.b.c.d 80:30284/TCP 12m ... Upload a sample MNIST dataset located in samples/ directory, such as 6.jpg. After uploading MNIST sample, web page shows prediction result.
