Short communications: A note on flight disorientation over smooth water We compare the Kolmogorov and entropy numbers of compact operators mapping from a Hilbert space into a Banach space. These general findings are then applie... I Parker,A Graham 被引量: 0发表: 2018年 加载更多0...
The second part of the study examines the influence of noise and constant bias on entropy values. In addition to external noise, the hyperparameter (bias) used in entropy calculation also plays a critical role. Our study examines three different time series data types (chaotic, periodic, and ...
Among these possible solutions, we can note the prediction and in particular that of the prices of financial assets. The prediction of asset prices has been widely studied in the financial literature. One of the main objectives is the management of financial portfolios. In modern portfolio theory...
It is interesting to note that from the ANN-PSO result that the swarm populations sizes, mean square error, and root mean square error are significant in determining the optimum performance of the ANN-PSO model on the traffic datasets from the N1freeway; such as the lower the RMSE, the ...
Pangaea extracts k-mer histograms and tetra-nucleotide frequencies (TNFs; Methods) of co-barcoded reads and represents them in low-dimensional latent space by Variational Autoencoder (VAE; Methods; Supplementary Note 2). Pangaea adopts a weighted sampling strategy on training VAE to balance the ...

An alternate index used to quantify very short-term BPV within the context of time series data is sample entropy (SampEn). SampEn serves as a robust indicator of the degree of disorder or 'surprisability' inherent in a system and provides meaningful information on very short-term BPV [13, ...

Models based on decision trees (or ensembles) often outperform other models, including neural networks, in regression problems. It is interesting to note that SVR and MARS achieved competitive average results considering the evaluated metrics. However, the presence of outliers for both models had a ...
