Python Machine Learning Tutorial #8 - Handwritten Digit Recognition with Tensorflow

In this video we are putting the theory into practice. We design a neural network which recognizes handwritten digits. For this we use Tensorflow!

Just watched the whole series and it was great !

hello! I really appreciate the effort and time that goes into this video and I am sure I can answer for most when I say we are grateful for such a tutorial. I have one question that is the data used for training was not our own dataset but how did it look like if we are preparing our own dataset. the labeling techniques, grouping classes, and such data organization steps.

[minutes]

Clearly explained. Great. Please add images and flow charts like diagrams, so that it will be useful to beginners like me.Thanks

[arashshiri]

Thank you man, it was amazing. Could you do it for a livestream camera. I mean by putting a picture in front of camera and showing the result in computer?

[peschebichsu]

Amazing video! Could you do also explain, how you would do this if you have a PDF document with 1 handwritten digit (not always at the very same place). How would you achieve for it to only read the handwritten digit and ignore the rest of the document?

Fantastic series. The predictions were off, so I suspected my writing was different to the training images. If you use:
img = x_train
for i in range(0, 30):
    plt.imshow(img[i], cmap=plt.cm.binary)
    plt.show()


to flick through the images then you can see how the numbers look like. For me numbers were too fat, if you can write with line width 2, it works better.

Just cant get the number 4 to get predicted correctly. 😁

Hey, great video! I am getting a very low accuracy and high loss ( 0.098, 2.3025851249694824 respectively). What could be the reason for this?

[niklasd]

Which images are you using? From urself or from a dataset? Created with paint? Nice Video btw.

[jaspreetmonga]

do model.predict takes array of various images as input or can take a single image also? I am facing error when i pass single image.

[rianyouta]

this video help me with my study, i like your video dude! btw is this using CNN? what kind of model for this code??

[emadyounan]

Good morning
Thanks really for your video
I just have 2 or 3 questions i hope you answer me

Well i'm trying to make ocr for my company and we are scanning documents into tiff images so i need to read texts like batch_number and get the numbers after it
So how can i do that?
Why you choose 28*28?
Thanks

Hey great tutorial!
What should I do if I get this error: AttributeError: module 'keras.api._v2.keras' has no attribute 'Flatten'

[Joffrerap]

As a beginner in machine learning, loved the tutorial.
i just have a question, why normalize the data along the axis 1? seems kinda random, isn't the axis 1 the column of the images? like if a column has a lot of dark pixels, each pixels are gonna get grey, where as if it has only 1 grey pixel, it's gonna get darker.
Wouldn't it be better to divide every elements of the x_train tensor by the biggest element in the tensor (ie 255)?

Bro writes his 5 like a serial killer 💀

[gauravdesai]

is it possible for you to make a video to recognize double digits or any no. of digits?

[kookiescream]

I am getting this eror when reading the images.
TypeError: 'NoneType' object is not subscriptable
what to do?

[shivmu]

Hi, im using google collab but it wont let me load the csv file of the images is there anyway to solve this?

[pakjuaan]

Great video! Everything was well explained. I have one question though. I have included model.save('digits.model') in the code but somehow it is not creating the folder. Any ideas on how to fix this?

[ruizdani]

if i want traine the models with leters, what do you recomended?

[pccc]

Can i use for image which greater than 28x28?
