Simulating water dynamics related to pedogenesis across space and time: Implications for four-dimensional digital soil mapping

open access: yesGeoderma
Digital soil mapping (DSM) relies on machine-learning and geostatistics to represent soil property observations across space. DSM techniques are powerful but often empirical, being limited to the quality and density of point samples.

Radyo frekanslı (RF) pedometre tasarımı

open access: yes, 2021
Süt sığırı yetiştiriciliğinde verimlilik ve ekonomik durumu etkileyen başlıca faktör üreme performansıdır. Üreme performansına etkili en önemli faktör ise kızgınlığın doğru olarak belirlenmesidir. Kızgınlığın zamanında belirlenememesi tohumlamanın gecikmesine, gebelik oranının düşmesine ve doğum aralığının uzamasına yol açmaktadır.

The problematic case of data leakage: A case for leave-profile-out cross-validation in 3-dimensional digital soil mapping

open access: yesGeoderma
Data leakage occurs when there is an overlap between the data used for model fitting and hyperparameter tuning, and those used for testing. This overlap biases the model performance, making it uninformative regarding the model’s ability to generalize ...
