Practical Deep Learning for Coders: Lesson 1

[@IbrahimSowunmi]

Compiling how I fixed this. 1) In the bottom right hand corner open up the notebook. Change the environment from "pin to the version" to "Always use latest environment". 2) ddg_images has been deprecated - from duckduckgo_search import DDGS def search_images(keywords, max_images = 30): print(f"Searching for {keywords}") return L(DDGS().images(keywords,max_results=max_images)).itemgot('image') Use this function instead. Like for visibility.

As a middle aged hardware enginner I went to a ML workshop at work which started with, "So is everyone familiar with matracies". All the graduates nodded. So fast ai is a tool that looks hugley benificial . Cloud based jupyter notebook is a big nono for industry security though so im running in pycharm which isn't so straightforward but works so far. Many thanks for this development.

around 53:15 you explained that fine_tune method teaches the model about the difference between datasets. From the docs I understand that the argument you pass in to the method is number of epochs. what is an epoch? is it an attempt?

[@harshsharma03]

epochs is the number of steps you take (in say gradient descent for example).

I have more of a hardware background. Now I run a Real Estate Empire. I hired a programmer to write a program that would read legal documents, Identify the names and addresses in the document and send them to an CSV or XLSX file. Since I receive 150 pages a day it makes since to use AI to read the documents and output the prevalent information. I was told by the Python Programmer it would take 3 months to write the code, and a 100 hours to run the AI model on an NVIDIA A100 GPU. He wanted $8,000 to write the program! After doing some research I figured it would take 10-20 hours to write such a program and GPU time would be less than an hour. When I told the Programmer that I was taking AI classes online and even wrote a Python program that would convert Fahrenheit to Celsius and vice versa. (only 3 lines of code, Input, data, and output) He gave me the money back for the few hours he worked on the project and resigned. At this point I'm at the very least at Script Kiddie status and lack the skills to write this program. Is this program even doable?

[@tomas4298]

In the video Jeremy mentions that for tabular data we normally won't have a foundational or base model to fine tune and that's fast ai uses fit_one_cycle. For the use case of creating a recommendation system wouldn't it make sense to say that my first version of the model becomes my foundational or base model and as I get new data from users I could fine tune that model? That will save me costs and effort same as foundational models do, or am I missing something? I could keep iterating this same way and then fine tunning tabular data and starting up with a pretrained model will make sense. I'm sure I might be missing something but cannot think on what it is.

[@jntb3000]

Hi Thanks for the great video. I went thru the bird and forest examples. Work great. I have a question for you about regarding weights (at about 1:15:50). Generally, as more inputs are fed into the model, the weights are adjusted so that the loss gets closer to 0. But how can we prove the new weights won't make it worse for the previous input? How can we ensure that the model will merge toward lost=0 for all inputs? I still can't understand how the adjusted weights after the 1000th image still good for the 1st image. Thanks

[@danielquandt9953]

Hey Mike! You probably have this answer by now, but the loss function is generally computed across all inputs (or a statistically representative sample of them) before updating the weights, rather than going one-by-one.

[@jntb3000]

@@danielquandt9953 Thanks, that helps explain it. I understood it wrong all this time ;)

[@shivashrestha1061]

can someone help? I tested this model with a car image, and it outputs as a 100% bird.😕

[@john-mcdonnell]

One thing that bothered me a little bit: Howard says roughly "we can learn anything if our model can represent the function." But there isn't actually a promise that you can hill climb into a good set of weights just because the model is capable of representing a good function. A lot of the work on improving architectures is about improving learnability, not representability. For example, in theory shallow networks of arbitrary width are universal approximators, but in practice we have gotten better learning performance by making networks deep.

[@vme90-y7l]

It would be nice if there was an option to change the bright white background to a softer darker color that's easier on the eyes.

[@ElvisRandomVideos]

I found interesting that you didn’t go into details on the tabular section of the presentation. I believe that is the only section we don’t have pre-learned models to assist. The example you showed was only able to achieve a 0.6 loss on trained data.

Thanks for the video! It's really valuable information that pyTorch is 'better' than tensorflow. May I ask if it's possible to run pyTorch in MATLAB?

[@maxdehoyos9920]

Python and MATLAB are both interpreted languages. pytorch, however, is a Python library to help users implement deep learning workflows. These workflows are typical, and there are some tasks that always need to be done. pytorch defines the steps in the workflow using Python’s language features, so users don’t have to build the context for these common (and complex) operations from scratch. In short, pytorch makes sense to the Python interpreter; MATLAB’s interpreter doesn’t have the context to interpret the lines of code in the pytorch package.

[@maxdehoyos9920]

Keras, another Python deep learning package, has a great blog explaining its design philosophy. From its results in popularity polls, it’s clear many developers are grateful for the design of the Keras API. It might not be as optimized/performant as PyTorch, but its API design makes it a viable option. Quite a few companies still feature it in their hiring requirements. Ultimately, we want to coordinate with other people. Keras seems to facilitate just that.
