。《Approaching (Almost) Any Machine Learning Problem》是一本侧重于应用机器学习模型的书籍,它基于作者参加Kaggle竞赛的丰富经验。这本书的作者是Abhishek Thakur,一位在Kaggle竞赛平台上获得Grandmaster称号的顶尖选手。书中的内容不仅包括了数据预处理、模型选择和评估等机器学习的基本步骤,还提供了实用的代码和方法论...
Almost all machine learning procedures rely on the illusion that the observed data are typically distributed. The training data suffers from (a) the curse of dimensions (b) the presence of skewness. The high dimensional data hampers the classifiers' performance, whereas the skewed data is the ...

The problem with this approach is that it may lose lower optima which may lie on a crossover path to higher optima. Maintaining diversity in the population was the main goal of this approach and algorithm was successful to some extent, but stochastic errors by the low value of crowding facto...
We note that this problem represents the worst-case scenario for the computational funnel approach, and is characterised by reasonably constructed, yet poorly correlated fidelities, as demonstrated in Fig. 5. We also note that the success of the single fidelity Bayesian optimisation algorithm (EI) ...
Airport flight delays continue to be a major problem that has an impact on both airport and airline operations. If aviation system decision-makers want to stay competitive, they should prioritize the inclusion of flight delay estimates in their insights at the multi-level. The suggested method for...
Machine learning approaches using satellite imagery are providing accessible ways to infer socioeconomic measures without visiting a region. However, many algorithms require integration of ground-truth data, while regional data are scarce or even absent
Figuring out how to distinguish these uses (not to mention other interpretations of the question) is a challenging machine learning problem. But intuitively, What’s the weather going to be like? means the same thing in both cases—the user wants to know the weather at the time and place ...
In the latest fourth generation, problem domains that are interactive with environmental factors as robotics systems, drone trajectory prediction, structure and properties prediction of complex materials, and so on are solved by updated algorithms deep reinforcement learning, GAN, autoencoder, and ...
Thus, RL was introduced to solve the irrigation decision problem with the Markov property. 2.5.1. Environment of RL RL refers to a method of machine learning in which an agent interacts with an environment through a sequence of observations, actions and rewards. The goal of the agent is to...
