P Learn diffusion models with Hugging Face course 🧨
Hi there, it's Lewis here from the open-source team at Hugging Face 👋
Since the release of Dalle-Mini and Stable Diffusion a few months ago, you may have seen your timelines filled with impressive text-generated images like the one below:
Image generated with textual inversion and Stable Diffusion
These images are generated by an exciting branch of research called diffusion models, which is rapidly being applied to generate novel structures in computer vision, audio, and even molecular biology 🤯!
To help the community get up to speed on this fast-moving field, we've joined forces with the awesome Jonathan Whitaker to launch a free course on all aspects of diffusion models 🔥
In this course, you will:
👩🎓 Study the theory behind diffusion models
🧨 Learn how to generate images and audio with the popular 🤗 Diffusers library
🏋️♂️ Train your own diffusion models from scratch
📻 Fine-tune existing diffusion models on new datasets
🗺 Explore conditional generation and guidance
🧑🔬 Create your own custom diffusion model pipelines
The course will be released in a few weeks and you can register via the signup form here: https://huggingface.us17.list-manage.com/subscribe?u=7f57e683fa28b51bfc493d048&id=ef963b4162
Looking forward to meeting you all in the course 🤗!

D DALL·E to be made available as API, OpenAI to give users full ownership rights to generated images
Email announcement from OpenAI below:
> DALL·E is now available as an API
> You can now integrate state of the art image generation capabilities directly into your apps and products through our new DALL·E API.
> You own the generations you create with DALL·E.
> We’ve simplified our Terms of Use and you now have full ownership rights to the images you create with DALL·E — in addition to the usage rights you’ve already had to use and monetize your creations however you’d like. This update is possible due to improvements to our safety systems which minimize the ability to generate content that violates our content policy.
> Sort and showcase with collections.
> You can now organize your DALL·E creations in multiple collections. Share them publicly or keep them private. Check out our sea otter collection!
> We’re constantly amazed by the innovative ways you use DALL·E and love seeing your creations out in the world. Artists who would like their work to be shared on our Instagram can request to be featured using Instagram’s collab tool. DM us there to show off how you’re using the API!

No one is hiring juniors/ mid-level data scientists
Is it just me or are the vast majority of job adverts on linked in right now for senior/lead/principal data scientists? (UK btw)
I only saw a single advert for a junior role and this had over 200 applications in just a few a hours of being released.

Question Using percentiles with a very skewed distribution...how to explain why this is wrong...
I am researching a jurisdiction which ranks communities on a variety of indicators that are Census variables. Three of the four indicators are normally distributed, but one (proportion of new immigrants) is very heavily skewed. Essentially, only a handful of communities have any immigrants.
The rankings are presented as percentiles, however the distribution's skew is so great that once you get past the communities that comprise the top ten percentiles, the communities are essentially zero. The practical significance of being 1st percentile vs 50th is meaningless. It might be a dozen people in a community of thousands.
I am struggling to explain why this is problematic in professional terms.
Can anybody offer some suggestions?

Q In Bayesian statistics, what does the posterior distribution of a parameter for a given datapoint really give us?
I'm a little new to statistics and working through Richard McElreath's Statistical Rethinking. In chapter 4, we fit a linear model on a dataset of weights and heights (written in R):
height ~ dnorm(mu, sigma)
mu <- a + b(weight - mean(weight))
a ~ dnorm(178, 20)
b ~ dlnorm(0, 1)
sigma ~ dunif(0, 50)
(I don't think the specific numbers in the distributions matter for this questions.) We later extract a large number of samples from the posterior distribution of the model after fitting it and then "make a list of 10,000 values of mu for an individual who weighs 50 kilograms". (extract.samples() is a function in the library provided by the book, m4.3 is the model we have fit, and post contains samples 10,000 posterior samples of a, b, and sigma):
post <- extract.samples(m4.3)
mu_at_50 <- post$a + post$b (50 - xbar)
What do the samples in muat50 really mean? Are they the possible values of mu that fit our model if we only have a single datapoint where weight = 50 when we hold the other parameters (a, b, and sigma) constant (at the values that fit our entire dataset)?
This came up in a section talking about plotting regression intervals and contours, so I get what muat50 is supposed to do (give us an confidence interval around our regression line at a single point, then when we can compute the confidence intervals around every point to visualize our interval), I think I'm getting tripped up by the notion of holding a value like weight constant when sampling a parameter like mu and what those samples mean.
