    End of your experimentation,

    Which plateform do you use to run your predictif model ?

    I'm interest to process data in this way.

    I'm busy in my darkened room in an attempt to refine this process. The software I'm using is Neuroshell Classifier from the AI Trilogy package. (I've had this for years now ~ back when it was less than a quarter of today's price!)

    Their classifier is unique, so far as I know, inasmuch the predicted output is not restricted to two state binary, but can be as many variants as the user chooses (I've been restricting possible outputs/scores to every variant between 0-0 & 3-2)

    . . . but still work in progress!

  2. Correct scored round-up. No profit from these first ones, but very early days yet. A combined summary is printed here which also includes a handy comparison of my ML picks against backing every game to finish 1-0, every game 1-1 and every game 0-1. Finally the predictions from a web site that puts its correct score on line for free (Bettingclosed.com)

    A couple of Brazil Serie A best-bet picks from this method to add to the above;
    (one result in so far, win at 1.92)

    26-Aug-18 | 20:00 | America MG | Flamengo RJ   away win 2.41
    26-Aug-18 | 23:00 | Vasco | Chapecoense-SC    draw   3.32 
     

    Well, the above two additions both lost leaving a poor return for the weekend's 7pt outlay. Just a single winner from the seven proposed and an overall loss of 5.08pts.

    I'm pinning greater hopes on my revised correct scores engine to rescue this thread.

    Blackburn v Reading  1.73    (2-2 incorrect)

    Watford v Crystal Palace   2.50      (2-1 correct)

    1 winner, 1 loser for a 0.5 profit

    +5.29 from 12 bets, 44% yield. Nicely on track!

    Nothing for the coming week ... unless Tottenham lose to Man Utd tomorrow, at which point next weekend's Watford v Spurs will be a home win bet (should be around 5.0 for that)

  5. I've been looking further into various options for this experiment in artificial intellingence football predictions. Using goal differences instead of simply the three options of Home/Away/Draw that I began with didn't appear to get me any closer to a solution. However, using a classification method with correct scores did show some promise . . .

    Again, nothing but current league results to date (where the engine assumes each team's home & away results are two distinctly separate individual teams). Results used are all those where the home and away sides scored 2 goals or fewer, and other scores are all lumped together as "other". This approach I figured was working with more than 50% of all results, and I wasn't really bothered about attempting to predict EVERY game, rather than to concentrate on those games where scores were more 'reasonable' and as such perhaps allowing a little more confidence in the outcomes.

    We shall see, can this possibly make a level stake profit?

    The 3 most common football outcomes are 1-0, 1-1 & 0-1. So, I'll use these scores as control variables, logging the percentage hit rate and profit/loss for each and comparing progress.

  6. Two from three for a profit is okay. But I've re-analysed and re-thought my methods.

    I'm still using nothing more than season results to date to build the networks, no odds are used, no winning margins, just the season's win, draw & away records. I do have a very small sample now to help see how it is performing, and near to perfect P=1 is required to trigger a bet ~ but still work in progress.

    This weeknend's matches are reprinted here in full showing all network P values for HOME,DRAW or AWAY.
    My best bets are shown to the right hand side.

  7. 14 correct from the 38 picks (including the Brazil games) is not a start I would have wished for. -12.83 from a 33.8% strike rate and a -33.76% yield. But this thread is experimental and my thinking-in-progress, so all is far from doom & gloom.

    My neural net classifier gives a binary decision on each game. For my first run, with last weekend's fixtures I merely selected the outcome with the highest network 'probability' for every match, with a no bet where two oucomes were too close to call. Better I think to select only the very best of the picks where the net is suggesting a near certainty. I'm not naive enough to think such games will be anywhere near the certainty suggested, but they will be the cream of the crop.

    Elsewhere I've expressed my opinion that football draws are probably the hardest outcome to predict, and my weekend sample, although comparatively small, suggested 7 such outcomes - and every single one failed! Not a proof by any means, but something to keep in my mind.

    So, the Brazil net newly trained with the latest results and bearing the above thoughts in mind, we have three midweek selections; ALL HOME WINS:-

    . . . and I need to cross check team names are consistent in each league over the course of the season, I noticed some small differences in the Premiership teams that I had to change before it all worked properly.

     

    Team names can be a nightmare when trawling information from multiple sources. The number of variants appears to be directly proportional with the obscurity of the league.

  9. Many football rating methods are compiled on a match-by-match basis in real time, inasmuch a ratings is assessed for a game at hand, then using the result of said game, the rating is adjusted accordingly. The most recent match therefore has perhaps too much of an influence on how the new rating moves.

    This approach presented here also uses past results to calculate the outcome, but it looks at ALL previous game results and treats them as equally important. Trends therefore are not picked up, whichever way a team's form is heading is totally ignored. A good or bad thing? . . . let's find out.

    I'm using neural/genetic machine learning to process season-to-date league results to find the best fit of correct home, draw, away predictions to then apply to the next set of fixtures. In order allow the algorithms enough relevant information and data it is thought necessary to employ only where a league season is half completed.

    Other caveats include no leagues of more than 20 teams so as not to overwhelm the net (and take far longer to process). No leagues with too few teams either where teams may play each other more than twice ~ nothing confuses artificial intelligence more than encountering the same situation with different outcomes, e.g. United v City showing one home win and one away win.

    Having churned through a few leagues here's what it gives for this weekend; (odds are Oddsportal average odds from 50 odd bookies)

  11. Best of luck with this @neilovan

    I've had over 20 years with ML models, wouldn't go anywhere without them and my betting wallet has seen the benefit. Just a personal view here, but I find it strange that you've focused your attention on football draws.Your past data will show that a level stake bet on each of home win, draw and away win will show the biggest loss to be in the draw column. Does this suggest that the bookies tend to underprice the draw because it is sooo difficult to predict with any degree of certainty?

    Again, I won't knock your project here, but maybe turning your attention to home wins could (would?) allow a higher win% from more bets? But I'm probably preaching to the converted and you have tried that route and dismissed it.

    However, fortune favours the brave, so good hunting. I'll be interested to see how it pans out.

  12. Everybody and his dog 'knows' this is going to be a high scoring game. Just the occasion when, because each team also know the dangers of their opponents attack, they will concentrate more on not giving anything away.

    For me it has all the hallmarks of a 0-0 at 90 minutes.

    Having said that, should a goal be scored in the first half, then the game profile changes and a hat-full is possible. But for me that doesn't make the odds of 23.0 available for 0-0 correct score (Skybet) a poor value bet, even if used as a small stake saver with whatever else you think may happen.

    I was about to congratulate you on being a successful soccer bettor following your first two paragraphs but then you seem to not be a profitable football bettor according to the third paragraph? 

    So I take it your 6 figure winnings ( I assume you meant profits ?) are on other sports ? I’m curious to know which sports and if it’s not too much trouble what it is about you that you think enabled you to win? I’m also surprised to see thst none of your accounts has been closed . 

    My winnings were predominantly from horse racing daily markets.

    I suppose my research allowed me a better idea of the outcomes. There are acquaintances who have won more money than I with spread betting and still have their accounts open. In my experience spread firms are much more tolerant than traditional bookies. For example I also had winning sports spread accounts with IGIndex, Spreadfair, City Index, etc., before they ceased operations, none of them were closed down.

    The 'good times' were up to about 3 years ago, at which time it appeared the spread firms' improved their analysis and my edge was eroding. I took a 1 year sabbatical, but 'missed' the buzz and have been active again for the past couple of years. Much reduced stakes now though, and far fewer opportunities, over this time I'm just over 12K in front, but it's an enjoyable hobby!

    Finally,I’m sorry to correct you but with respect you’re wrong to say football is hard to crack.

    As I said earlier long term football markets are easy to beat.

    Apologies. I always think of football betting on a game by game basis and individual matches.
