It can have zero, one or many filters. Filters narrow down the query results based on the given parameters. In SQL terms, a QuerySet equates to a SELECT statement, and a filter is a limiting clause such as WHERE or LIMIT.You get a QuerySet by using your model’s Manager. Each ...

Hyperparameters were optimized using GridSearchCV() function in Python. Finally, we evaluated the performance of ML algorithms. Our study can be regarded as a multi-class classification problem for classifying three categories. Therefore, we employed precision, recall, F1 score, and accuracy suitable...
Cross-validation employing three folds facilitated the optimization of model hyperparameters, with the lambda.min rule used to ascertain the optimal penalization parameter. Nomograms were subsequently devised based on the trained models to visually represent the anticipated probability of 3-year PFS after...

We experimented with different NLP pre-processing techniques (e.g., lowering case, punctuation removal and tokenization) and various hyperparameters such as dimensionality of word vectors, minimum word frequency, epochs, negative sampling (Word2vec and fastText), window size, and learning rate (alpha...
vemade the design configurableto fit different size spools and generate different size trays. The parameters to fit a specific spool size are fairly straightforward if we already have one such empty spool in hand: get out some measuring tools and maybe do some math. But the parameters for the...
Parameters that generated the best accuracy were retained. We evaluated our model in the testing set (internal validation) based on sensitivity, specificity, PPV, negative predictive value (NPV), F measure, and area under the curve (AUC). We further explored feature contribution by extracting the...
