Field-aware Neural Factorization Machine for Click-Through Rate Prediction
This work addresses the challenge of improving prediction accuracy for recommendation systems and online advertising, which impacts user experience and revenue, but it is incremental as it builds on existing feature combination methods.
The paper tackles the problem of automating feature combinations for click-through rate prediction by proposing the Field-aware Neural Factorization Machine (FNFM), which combines second-order feature interactions with deep neural networks for higher-order learning, resulting in stronger expressive ability than models like DeepFM, DCN, and NFM.
Recommendation systems and computing advertisements have gradually entered the field of academic research from the field of commercial applications. Click-through rate prediction is one of the core research issues because the prediction accuracy affects the user experience and the revenue of merchants and platforms. Feature engineering is very important to improve click-through rate prediction. Traditional feature engineering heavily relies on people's experience, and is difficult to construct a feature combination that can describe the complex patterns implied in the data. This paper combines traditional feature combination methods and deep neural networks to automate feature combinations to improve the accuracy of click-through rate prediction. We propose a mechannism named 'Field-aware Neural Factorization Machine' (FNFM). This model can have strong second order feature interactive learning ability like Field-aware Factorization Machine, on this basis, deep neural network is used for higher-order feature combination learning. Experiments show that the model has stronger expression ability than current deep learning feature combination models like the DeepFM, DCN and NFM.
