Different scores like accuracy, precision, recall, F1 for evaluating embedding models
Common evaluation metrics for embedding models include accuracy, precision, recall, and F1 score
Accuracy measures overall correctness of the model's predictions
Precision measures the proportion of true positive predictions among all positive predictions
Recall measures the proportion of true positive predictions among all actual positiv...
Embedding models learn to represent words or entities as dense vectors in a continuous vector space.
Embedding models map words or entities to high-dimensional vectors where similar words have similar vectors.
These models are trained using neural networks to learn the relationships between words based on their context.
Popular embedding models include Word2Vec, GloVe, and FastText.
Embedding models are commonly used in na...
Precision is the ratio of correctly predicted positive observations to the total predicted positive observations, while recall is the ratio of correctly predicted positive observations to the all observations in actual class.
Precision focuses on the accuracy of positive predictions, while recall focuses on the proportion of actual positives that were correctly identified.
Precision = TP / (TP + FP), Recall = TP / (TP + ...

Linear regression is used for predicting continuous numerical values, while logistic regression is used for predicting binary categorical values.
Linear regression models the relationship between a dependent variable and one or more independent variables using a linear equation.
Logistic regression models the probability of a binary outcome using a logistic function.
Linear regression is used for tasks like predicting hou...
