Everything I understand about chatgpt

ChatGPT Resources

Context

ChatGPT appeared like an explosion on all my social media timelines in early December 2022. While I keep up with machine learning as an industry, I wasn't focused so much on this particular corner, and all the screenshots seemed like they came out of nowhere. What was this model? How did the chat prompting work? What was the context of OpenAI doing this work and collecting my prompts for training data?

I decided to do a quick investigation. Here's all the information I've found so far. I'm aggregating and synthesizing it as I go, so it's currently changing pretty frequently.

Params: input_shape -- the shape of the images that are input to the model
in the form (width_or_height, width_or_height,
num_color_channels)
Returns: model -- a model that has been defined, but not yet compiled.
The model is an implementation of the Unet paper
(https://arxiv.org/pdf/1505.04597.pdf) and comes
from this repo https://github.com/zhixuhao/unet. It has

This is an example that performs stacking to improve mean squared error
This examples uses 2 bases learners (a linear regression and a random forest)
and linear regression (again) as a meta learner to achieve the best score.
The initial train data are split in 2 halves to commence the stacking.

'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats
