An implementation of Deep SHAP, a faster (but only approximate) algorithm to compute SHAP values for deep learning models that is based on connections between SHAP and the DeepLIFT algorithm. MNIST Digit classification with Keras- Using the MNIST handwriting recognition dataset, this notebook trains...
An explanation of why an instance is anomalous enables the experts to focus their investigation on the most important anomalies and may increase their trust in the algorithm. Recently, a game theory-based framework known as SHapley Additive exPlanations (SHAP) was shown to be effective in ...
The Shapley additive explanations (SHAP), as proposed by Lundberg and Lee (2017), is one such XAI-based algorithm. The SHAP algorithm can be used to understand how each feature contributes toward a specific output from an ML model and has recently been adopted in many areas, including ...
Second, in this workflow, SHAP (SHapley Additive exPlanations) was selected to explain the findings of machine learning models. SHAP is a powerful approach that was developed to explain the output of any machine learning algorithm at the global and local levels. Locally, they explain why a given...
While SHAP values can explain the output of any machine learning model, we have developed a high-speed exact algorithm for ensemble tree methods (Tree SHAP paper). This has been integrated directly into XGBoost and LightGBM (make sure you have the latest checkout of master), and you can use...
算法的复杂度 算法(Algorithm)简单来说,就是能在有限时间内对输入进行正确处理,并输出结果的一系列指令的集合。衡量一个算法优劣的我们可以从时间和空间两个维度来展开。算法的时间复杂度 由于不同硬件设备上算法的执行时间差异可能就会比较大,此时直接使用算法的执行时间来表示算法的优劣就显得不那么可靠。
The deep neural network model that has been chosen is subsequently subjected to weight optimization, in which the Particle Swarm Optimization (PSO) algorithm is utilized to fine-tune its hyperparam- eters. Particle Swarm Optimization (PSO) is a widely rec- ognized iterative technique that ...

XGBoost, a powerful machine learning algorithm, is employed for modeling, with hyperparameter tuning optimizing its predictive performance. The model's results are then made transparent through SHAP analysis, which identifies the most influential variables affecting incident duration. The understanding ...
First, the policyholder can appreciate whether the decision of the algorithm was based on fair or unfair attributes. Second, they can determine whether the important features are actionable. To illustrate, if weight appears to be a relevant factor for a policyholder of age greater than 50, the ...
