Both the bettor and the bookmaker can be equally skilled in predicting the outcome of a match, however the bookmaker sets the rules for the bet and thereby guarantee themselves a profit in the long run. The way they do this is by controlling what is called the payout. Here is a quick example. But what is the expected value of your return, X?
So in the long run, each dollar spent resuls in 95 cents return, and you will make a loss! However, the discussion generalizes to other sports too. What we have seen above is that bookmakers make a profit by controlling the payout. In order to do so they have to set the odds accordingly. For this, they need to know the probabilities. An omniscient bookmaker who gets all probabilities spot on cannot be beaten in the long run. But bookmakers are not omniscient and therefore there are two ways in which they can be beaten, purely based on estimating the probabilities better.
In fact, strategy 1 is just a specific version of strategy 2. Nevertheless, even if you manage to predict each game more accurately than the bookmakers, you are unlikely to make a profit, since the bookmakers get pretty close to getting the probabilities right. This can be seen from Fig. The dashed black line corresponds to being able to predict the probabilities perftectly for an infinite number of games.
Since the blue line stays pretty well within the grey bands. But they could still be wrong on a number of individual games. Strategy 2, as outlined above, relies on identifying where the bookmakers misjudge the actual probability. For instance, in the unrealistic event where the bookmaker would offer equal odds, e.
The goal is to identify all such games. However, since most of the time it is not easy to tell when the bookmakers are wrong, we can try to have a machine-learning ML algorithm do this for us. For the purpose of this project we used darts statistics, including features such as averages, checkout percentages, number of s maximum score with 3 darts and head-to-head statistics.
In addition, we used historic odds in order to assess whether this model could have made a profit. First, to further motivate our tactics of only betting on a selection of games lets consider the benchmark accuracies.
Clearly we are not outperforming the bookmakers, so there is little chance to make a profit. The binary-cross entropy loss function optimizes our ability to predict the outcome of games correctly, i. However, that is not our goal. What we want is to identify the games where the bookmaker misjudges the true probability and thus offers favourable odds. Below is a loss function constructed to do exactly this.
Nonetheless, classic classification models are not well suited for betting strategies, and one needs to use a custom loss function in his neural network to achieve better profitability. We explain why below. Decimal odds are the ratio of the full payout to the stake. Note that odds inverse gives the implied probability of being right. Hence you want to bet on teams with the lowest odds, i.
For the sake of illustration, we design two basics strategies:. Assume that we have odds 5. Chelsea has odds of 1. Betfair is one of the biggest betting exchange, and its API contains exchange markets navigation, odds retrieval, and bet placement operations. The bar charts above represent the accuracy and profit achieved by both betting systems. Accuracy means the number of times our bets were correct, divided by the total number of bets in that case.
Much data is involved when deciding on which team to put our money. For this reason, betting is an ideal subject to apply one of the most popular machine learning techniques, Neural Networks. In particular, we could use a classification neural network. A classification NN is ideal when applied to problems for which there is a discrete outcome, or said otherwise when identifying for which category belongs a particular observation.
Applied to sports betting, we could devise a neural network with three simple categories. Below is the architecture of such a network. However, from our previous example with two simple betting strategies, it is clear that we are not trying to predict the outcome of the game, but rather what bet would be the most profitable.
Applied to a classification neural network, this would result in the following architecture. We end up with a multi-label classification problem not to be confused with multi-class classification as the outcome of a game could result in one or two predictions being correct. Not all bets provide the same reward. To take this into account in our neural network, we need to use a custom loss function. In standard classification neural network, we use loss functions such as the categorical cross-entropy.
However, this kind of functions would give similar weights to all bets, ignoring the profitability discrepancies. In our case we want the model to maximize the overall gain of the strategy. Thus the input of our custom loss function must incorporate the potential profit of each bet. We set up our custom loss function with Keras on top of TensorFlow. In Keras, a loss function takes two arguments:. Below is our custom loss function written in Python and Keras.
Steps are the following for each observation each game :. For our data we take a list of games from the English Premier League, season —, August to December It contains descriptive game data such as team names, odds from Betfair, and a sentiment score representing the percentage of positive tweets over the positive and negative tweets.
Data and Jupyter notebook available on my github page. Our data contain the outcome of each game in the form of 1, 2 ot This needs to be converted to a one-hot encoding vector representing the output layer of our neural network. Plus we add the odds of each team as elements of this vector.
This is exactly what we do below. Before training the model, we need first to define it. We use a fully connected neural network, with two hidden layers. We use BatchNormalization to normalize weights and eliminate the vanishing gradient problem. Then we train the model using a set of arbitrary parameters.
Once the training has completed, we look at the performance of our model with the following print command:. As we can see, we end up with a training loss of

Clearly we are not outperforming the bookmakers, so there is little chance to make a profit. The binary-cross entropy loss function optimizes our ability to predict the outcome of games correctly, i.
However, that is not our goal. What we want is to identify the games where the bookmaker misjudges the true probability and thus offers favourable odds. Below is a loss function constructed to do exactly this. The argument is our expected return: the odds multiplied by our estimated win probability minus 1. Given the properties of the ReLu function this means that it is only larger than 0 if we believe the odds are favourable for us. On the other hand, the more favourable the odds appear, the higher the amount the model will bet.
This loss function ensures that what we are optimizing is not how well we can predict the outcome of a game, but rather our winnings. Note that as a consequence of our custom loss function, the predicted probabilities are not representative of the true probabilities, since when the model thinks the bookmakers are off it will push the probabilities towards the extremes 0 or 1 in order to bet more.
In order to test our model performance we constructed a densely-connected neural network with two hidden layers. The final layer is a sigmoid layer that predicts the probability of player 1 winning. Using the bookmaker odds and the outcome of the game we then compute the loss with the custom loss function described above. Since this is a time-series, the model is trained on historical data upto a given point and subsequently applied to the next 50 games.
This process is then repeated for the next 50 games, etc. Results are shown in Fig. Red dots are for a strategy where we always bet a fixed amount on the player with the highest winning probability according to the bookmaker odds. Green dots are bets placed by our machine learning model. It only places a bet when it expects to make a profit. The total earning fluctuate around 0. Steps are the following for each observation each game :.
