Show HN: Learn time series with a story illustrated by Stable
Diffusion
We just published this tutorial about ARMA(p,q) models for modeling
time series, and how to fit them using Python. But while it's a
tutorial, it has a few twists. First, it's interactive: you'll
learn by solving problems and making choices. Second, it's a story:
you play a character in a plot that gives you real-life problems to
solve. And third, it's illustrated: we spent many hours hacking
with Stable Diffusion, GIMP, and matplotlib. This is chapter 3 in
our interactive course, Everyday Data Science. [1] The first half
of the chapter is free. You can get the whole course forever for
$29. These chapters are a lot of effort to produce, so please let
us know what you think :-) - Andrew Carr [2] and Jim Fisher [3]

| Hi, it's actually $29 for the entire course, of which this

| that if so!
| sliken wrote:
| Ah, that's a surprise. It went from 0 to 46% then it popped

| another 10-20 minutes. Maybe add a "$29 for this course/N
| chapters" or "$29 for a course and show the syllabus".

| Thanks for the reply! I can see now that it's not super

| see what I can do to clarify it.

|
| Edit: after actually using the site I see your point, the only
| indicator is the small text "free preview" which I probably
| wouldn't have noticed without first having read the Show HN
| post.

| Hi! Do you think there's any way we can make it clearer what's
| going on? I put "free preview" at the top, but perhaps it can
| be easily missed.
| merlincorey wrote:
| I also didn't notice the "Free Preview" on the progress bar

|
| As distasteful as it may be, an actual heading or otherwise
| strongly formatted text note near the top should suffice for
| most people.

| It looks like you cut the preview from 46% of this chapter to
| just 22% of the chapter... I went back to look for a quote
| from about 41% of the way through to explain to another
| commenter why the style is so effective and ran into the
| paywall earlier than I had my first time through. Just FYI,
| the content before 22% isn't strong enough to sell the
| preview. It has to get to the questions where you're asking
| for intuitive guesses on the real mathematical expressions to
| make it clear how valuable this is.
|
| Honestly, you should just be giving away this whole chapter.
| If you did then I could forward it to colleagues, let them
| learn this one concept and suggest they get the rest of the
| info.
|
| As it is I really can't do that. It'd be like giving a friend
| a flyer that was shoved under my door.

| Very cool. Are these interactive stories created with Twine?
| StrictDabbler wrote:
| I find myself irritated by how effective this method of
| instruction is.
|
| I'm not sure which is more annoying:
|
| -going through years of education in pure mathematics without
| this kind of tutorial
|
| -not having come up with this method myself, when it's _so close_
| to the dumbed-down edutainment software of the 90 's
|
| Every university course should start with at least a day of
| instruction written in this style.

| Heh, indeed, the similarly effective method if gamification.
| Even relatively "dry" things like algebra can be gamified,
| Dragonbox is a good example. From my limited experience (1
| kid), it works really well.
| eutectic wrote:
| Not to be rude, but I found it a bit infantilizing. I would

| StrictDabbler wrote:
| That's fair in a sense but it also looks like they moved the
| preview paywall much earlier in the chapter, 22% instead of
| 46%.
|
| Towards the middle of the chapter they start asking intuitive
| questions about how coefficients in the power-series map to
| the real-life concepts they've been discussing "childishly"
| up until then.
|
| It's a major turning point and I wonder if you just didn't
| get the opportunity to see that shift. It's infantilizing
| right up until it isn't.

| A product that takes a similar approach is: "A Curious Moon" @
| BigMachine [0]
|
| It's not an intro to time series or data analysis, but it's a
| great intro to Postgres, db administration, and etl that
| follows a fun and compelling storyline. The presentation is
| different, but the "edutainment" style is similar.

| Nice storytelling, and I love the images!

| jamesfisher wrote:
| Yeah, I used the perspective tool in GIMP for that. That was

|
| I was saying earlier, it would be cool if there was an ML tool
| for adding/modifying text in images. Similar to how there are
| additional tools for fixing faces, super resolution, and so on.
