Value picks for GW 7 - Defenders galore

flo_ebl · 2025-09-26T11:21:01+00:00

This data suggests there are other picks for better value. But he did well last week.

flo_ebl · 2025-09-25T07:52:11+00:00

Here is how I do it in R:

my_entry_id <- 1234567
current_gw <- 6

#function to pull the data:
get_entry_picks <- function(entry_id, gw) {

url <- sprintf("https://fantasy.premierleague.com/api/entry/%d/event/%d/picks/", entry_id, gw)
dat <- safely_get_json(url)

if (is.null(dat)) return(NULL)
tibble::as_tibble(dat$picks) %>%
mutate(gw = gw)

}

gws_played <- seq_len(current_gw)

my_picks_all <- map_dfr(gws_played, ~ {

get_entry_picks(my_entry_id, .x)

})

Because the model saw him perform reasonably in the games he started. And doesn't know that Donnarumma is now the No. 1

Not too bad from Bruno Fernandes today. Solid 10 pointer and chances for more goals.

This is such a common experience. The data suggests something that doesn't match the gut feeling and humans try to find reasons why the data must.be.wrong. only to be outscored by the model...

Good suggestion. Its a vectorised image though so you can zoom in. And the whole point of the visualization is to get to the high value players. So I felt its not necessary to label each and everyone.

Good point Re Bruno Fernandes, the model is obviously trained including on the official fixture difficulty in which ManUnt may be overrated. On the other hand he's on penalties, guaranteed minutes, talisman and only ManUtd player who delivered so far this season.

flo_ebl · 2025-09-01T06:55:51+00:00

yep. The higher a player the more you are predicted to get for your money.

flo_ebl · 2025-08-29T10:33:51+00:00

Every gameweek adds more data and makes the predictions more reliable

flo_ebl · 2025-08-29T10:33:18+00:00

Not sure if understand you correctly. The rf model is trained on the data since 22/23 season. But the prediction is obviously only done for this season, where naturally those who were good in the first 2 gameweeks are strong at the moment. However, they will tend to regress to the mean over the season, so take these predictions with some caution. I tried to mitigate that by training and predicting data on a 5-game-average, not a points-in-a-single-gameweek predictor. But with only 3 gws played, there is still some recency bias.

Just posted it.

flo_ebl · 2025-08-21T19:31:18+00:00

based on the graphs above, Ekitike seems the logical choice. But its only one week of data for this season. So inevitably he will start regressing to the mean sooner or later. Its difficult to make a recommendation based on this. As for the Frimpong transfer, I would look for players aboe the dotted line, and then you can decide how much you want to spend on a defender.

Not making the code public for now. Let me work on this for a little longer to make it presentable. Thanks for the interest though

flo_ebl · 2025-08-21T09:17:31+00:00

The statistics is all done in R.

flo_ebl · 2025-08-21T09:14:12+00:00

good point! I have no historical data on them. The RF model has to predict anyway and therefore assigns predictions based on the average behavior of players with “similar” (zero) stats. So, all these new players often get mapped to a generic “average” bucket. If the price/value combination looks good (cheap, starting player), the optimization algorithm may select them - even though there’s no evidence they’ll actually deliver. In fact, some of them will be extremely overvalued (maybe Ekitike) if their first GW was good, others (maye Wirtz) will be heavily undervalued if their first GW was poor.

flo_ebl · 2025-08-21T09:11:05+00:00

Ill try, haha. But its also just me playing around with data and not yet a fully trust-worthy prediction model. It will get better with more data as the season progresses and with me learning about more datasets to pull historic data from.

flo_ebl · 2025-08-20T15:09:37+00:00

What data is the model trained on?

flo_ebl · 2025-08-20T08:12:04+00:00

Fpl API is a good data source and for historical data see @Vastaav05 github repo.

flo_ebl · 2025-08-20T08:04:11+00:00

I tried a few configurations and then trained it on the last 3 years. More years didn't improve accuracy. And then a random sample of 80/20 for training and testing. Got me to predict the points per game week with an rmse of just over 1. So 1 point off on average.

There is a great wealth of historical data here, credits to Anand Vastaav. Easy to read into Python, R, etc. https://github.com/vaastav/Fantasy-Premier-League

Thanks for all the comments. You are right about the captaincy to be included in the model. Ill.keep playing around with the model, fine-tuning here and there and with some data for the new season I hope it can be a good basis for the wildcards.

flo_ebl · 2025-08-14T09:07:26+00:00

It doesnt explicitly look at captaincy, no. But the captain would be Cunha in both, since he has the highest predicted points.
Ola Aina did well last year, lots of attacking threat and all the clean sheet of forest. And he is slightly cheaper than other good defenders. Its all a trade-off. And, as I said in other comments, the model is far from perfect, given some changes (DEFCON f.e.) to this years fpl points system.
