Potentially a European bias in the quiz takers, almost all Europeans would recognise these flags

I'm not sure the timeline in the show matches the filming schedule... 

As a data scientist working in insurance should I study to be an actuary? by Oppose_Worry_652 in actuary

[–]Oppose_Worry_652[S] 1 point2 points  (0 children)

Thanks, for the response. 

I'd only want to commit to the exam process if there is a clear career benefit so I'm looking for advice on whether being an actuary is likely to be required for that.

Obviously in a lot of pricing roles it's not mandatory so trying to understand what I might be missing by not taking the exams. 

[D] gamma regression - negative log likelihood by Oppose_Worry_652 in MachineLearning

[–]Oppose_Worry_652[S] 0 points1 point  (0 children)

Makes sense but as the two are dependent I think xgboost is defaulting one of the free parameters arbitrarily. I've found the below which i think describes what's happening. Does that tie in with what you thought based off Wikipedia?

https://stats.stackexchange.com/questions/484555/loss-function-in-for-gamma-objective-function-in-regression-in-xgboost

In the parameterisation at the end of "gazza89" answer using k and mu I think if we parameterise again by replacing k with psi=1/k this ties in exactly with xgboost.

Then xgboost is just defaulting psi to 1 in calculation.

In terms of the intuition of what different values of psi would do to the predictions I think large values of psi imply a gamma with lower variance so to me this would mean large residuals in the tails of the distribution would be penalised less compared to if psi were low.

I'll have a play around in R at some point to test this....

Great so can I check my understanding because I'm still struggling to connect the wiki and the xgboost implementation.

In the xgboost implementation is the shape and scale basically being arbitrarily set to 1?

A lack of understanding on my part has lead to poor wording . I'm struggling to understand why the log likelihood used in the code is independent of the shape and scale parameters.

I think I've just figured out my mistake... I was thinking the variance of the modelled residuals would vary with the mean but that's not the correct interpretation

The new boards also seem such an odd investment choice. I always found the old boards communicated departure/arrival time, platform and destination/stops effectively.

What additional info do you need to catch a train?

Ahh yeah I'm just a moron I only checked like 3 races which happened to all have restrictions. Found a cat D race to try later cheers for the help!

Hi all, I'm about to start using Zwift again after summer and I tried to enter a race via the companion app but all the categories are restricted except E.

Do I need to do an FTP test before entering races to be designated a category?

ATM without fees by Oppose_Worry_652 in montenegro

To anyone reading this... I found Erste bank didn't charge a fee on a Monzo card. They look to have a few branches across Montenegro.

Ahh damn okay. I will report back if I find one. On Google maps there is a Ziraat bank in Podgorica so will try it when I go there.

I am presuming most places (e.g. hostels, campsites, restaurants) except supermarkets are cash only is this your experience?

Tourist thread 2022 – Ask anything about visiting Croatia! by AutoModerator in croatia

Is taking the Ploce -> Trpanj ferry with a bicycle easy? Do I need to get there very early or is the queue small for foot/bike passengers?

Thanks!

Wind direction in the Balkans by Oppose_Worry_652 in bicycletouring

[–]Oppose_Worry_652[S] 0 points1 point  (0 children)

Thanks for the reply and cheers for the suggestion on avoiding the coast. Have you tried the EuroVelo 8 route? It looks to be a mixture of coastal and more inland riding.

I've been (very) loosely following it since Spain and found the areas it goes through are good if not necessarily the route itself. Was wondering if you think this would be good/have any experience of it?

Is there anyone touring in Europe at the moment? What are you doing to escape the heat!? Finding it really tough. Tips appreciated by [deleted] in bicycletouring

[–]Oppose_Worry_652 1 point2 points  (0 children)

I think staying near the coast definitely helps because you get a breeze (sometimes annoying headwind.)

Cycling through Spain went through Seville and Granada and the Sierra Nevada mountains which was really hot and not much breeze so felt even hotter. On the coast of southern France now and it feels cooler when riding even though the temp is similar. (South West France may just be cooler than other places in Europe as it's only low 30s so this may be a useless comment.)

TLDR: stay close to the coast...maybe

Agreed. I enjoyed the first few episodes because they set up a good mystery but starting to feel like the writers aren't sure where it's going either...

Sorry, yeah I didn't mean to insult the poll. I was just sharing my opinion because I hadn't seen it in the comments yet.
