[💡SUG] Do you have training and evaluation speed reference benchmarks? about recbole

[batmanfly]

Thanks for this nice suggestion. We will discuss on this point and update the response soon.

To add a bit. The intent is not to creste a top performing benchmark in speed or accuracy. Rather, it would be a rough guide for users that provide parameters that work on a common platform (e.g. Colab K80) and and example of what to expect for runtimes.

Thank you for the consideration.

Thank you for the consideration.

Our team just had a discussion on this issue. We would arrange the test and give a rough time estimate of the implemented algorithms on some selected datasets with varying sizes. Hopefully, we would update these efficiency results on the main page or otherwhere before next Wednesday.

We would also inform you on this issue page.

BTW, your mentioned LightGCN issue is also important. I think if such a speed board was available, that issue might be clear. Our team also asked the implementer to locate the lines that are likely to yield the thrown memory exception. Will get back to you with the answer soon. A practical hint is that different algorithms may scale to varying-sized datasets. Graph based algorithms are likely to take up more space than other kinds of algorithms, which is likely to throw memory exception on large-scale datasets (e.g., Gowalla dataset). That is why we provide a series of data preprocessing functions in the library, e.g., K-core filtering. In the future, we would consider accelerating some competitive algorithms with slow speed (that would take some time, probably in 2021=) ).

Thanks again for your efforts with these suggestions!

@batmanfly (and @ShanleiMu )I saw this post today, which provides links to time and memory costs for general recommenders and sequential recommenders. Thank you.

I had a few questions/requests for those lists and figured this is a good Issue thread to post.

1. I believe the times here are in seconds-per-epoch, corrrect? (sec/epoch). If so, adding that will help clarify for new users.
2. I believe the memory is the GPU memory, correct? If so, adding that will help clarify.
3. Would it be possible to run on the Context-Aware recommenders too? I tried some of those yesterday and realized that adding side-features can dramatically slow down training in some cases (depending on # features, feature structure, etc)

Thank you again!

@tszumowski Nice suggestions. We will add these details to clarity our results.

For context- and knowledge- aware algorithms, their results are on the way=) We do find that some context-aware algorithms run more slowly than general recommendation algorithms, so that we didn't obtain their results by now. Their results are expected to be ready on this weekend based on current intermediate results.

@batmanfly great! You're all so fast and responsive!

[ShanleiMu]

@tszumowski We have added more details to clarify our results and updated the time and memory costs of context-aware recommenders and knowledge-based recommenders.

[tszumowski]

@ShanleiMu this is great! Thank you. I'll close this issue given all the great docs!
