LSTM preserves the historical information for text sequences and extracts the features using the RNN structure. The extracted features are used to run on machine learning classification algorithms like AdaBoost and XGBoost to perform the final prediction. Thereby the proposed ...

We trained and tested a variety of models on both binary and multiclass classification tasks using speech and text features. While binary classification models performed similarly to prior research (F1: 0.54–0.92), multiclass classification performance was markedly lower (F1: 0.35–0.75). By combin...
(or label), typically by a human expert. This annotated dataset is used to train a multiclass classification model using supervised learning algorithms. Emotion classification and intensity calculation using XGBoost [17,18], Support Vector Machines (SVM) [19,20],Naïve Bayes (NB) [21,22], ...
models on your smaller datasets, with much lower training costs than the ones involved in training the original model. JumpStart also includes popular training algorithms based on LightGBM, CatBoost, XGBoost, and Scikit-learn, which you can train from scratch for tabular regression and...
, but only used the more common models for the practical classification task, possibly overlooking other more accurate models. On the other hand, since GridSearch is extremely time-consuming (the XGBoost classifier takes up to 2 hours to run a grid search with even a small number of ...

Comparing the transaction flow graph with the non-Ponzi flow graph, and constructing seven statistical features to use XGBoost for classification. They achieved a precision rate of 94% and a recall rate of 81%, which performs efficiently in blockchains with sufficient transaction scale. Bartoletti...
To categorize articles and text into multiple predefined categories, use the multi-label text classification task type. For example, you can use this task type to identify more than one emotion conveyed in text. The following sections give information ab
