The timing on this is absolute gold, this is literally the type of project I'm building as a Django app for my work right now! It's an analytics dashboard to monitor sales activity by channel and since we're dealing with a lot of seasonality there, Prophet seems like a spot-on fit for incorporating forecasts. Thank you for doing this, excited for more of the series!

I have a question related to this video series and perhaps a request. As mentioned, I'm trying to make a forecasting proposal for my workplace and would like to cover all the basis that would be applicable from a data science perspective I built an RFM and CLTV customer segmentation Kmeans model based off e-commerce data from Kaggle and wanted to use these clustering to make forecasting prediction based off leads received and classified into the identified clusters. I will be forecasting total sales for the month using regression and wanted to know if this is something you would be doing on a day to day as a data scientist in a sales environment or am I missing a step?

I am starting out in DS (around a year into it) and I am really inspired by your content. Never used prophet but will make sure to run your notebook and accompany the series! Just curious, how long does it take you to make something like this notebook? I am struggling to execute faster and was wondering if you have any tips on that? Great content as always!
@TheAlmostAstrophysicist Жыл бұрын
Awesome! To make the notebook, took about I'd say 20-30 minutes since I've worked with prophet before! The hardest part was honestly finding good open source data lol. And the whole notebook takes about 20ish minutes to run if you go through the whole hypertuning cross-validation for every category of products! I have that notebook pipeline for video 2 finished!
@BryanCoronel0303 Жыл бұрын
this is nicely in-depth, thank you! in terms of scaling, would it be best to run this as a Python script instead of notebook and automate it using something like airflow?
@TheAlmostAstrophysicist Жыл бұрын
Thanks for watching! Absolutely! So you'd want to fully automate it as a pipeline, my second video (coming out Saturday this week) is a second full pipeline notebook and you'd want sometime like that pipeline either automated as a script OR you can use a service like Databricks/something similar to schedule regular notebook runs/jobs. :)

@niallwhelan2648 Жыл бұрын
Great series, thanks. Just on high volume you refer to largest sales by day, but is transaction volume not more important than total daily sales? High transaction volume will give better signal than low transaction volume.
@TheAlmostAstrophysicist Жыл бұрын
Great question! Absolutely - I think what you define as transaction volume is what I'm referring to when I say total daily sales. i.e. the higher the transactions are daily/the higher the volume, the better signal we get. In the video, I use the "np.mean" function across the columns to see what the average daily sales (i.e. avg. transaction volume) is. In general, the lower the volume, (under $1000 usually) leads to higher errors since it's hard to get signal. So I use >=$1000 as a cut-off. Does this make sense? I think we mean the same thing haha
@user-qe9hx1uj4l6 ай бұрын
Is there a way to deal with having lots of 0s in the time series? I'm currently working on a procurement forecast model. Therefore there are lots of days where procurement doesn't happen, making the y value 0 for most days. This is really affecting the model performance.

If you're given daily sales data and the agency that makes the order per day, what would you do to predict the sales per agency for a particular day? The data I have contains over 1000 agencies.
