WebI am solving a classification problem. I train my unsupervised neural network for a set of entities (using skip-gram architecture). The way I evaluate is to search k nearest neighbours for each point in validation data, from training data.I take weighted sum (weights based on distance) of labels of nearest neighbours and use that score of each point of validation data. WebHowever, how to evaluate sentence embeddings is also challenging. Here, we use clustering to evalu-ate sentence embeddings. Also, we prepare sets of sentences sorted by genre and use BERT models to get embeddings of each sentence. Then, we cluster those embeddings and evaluate models with cluster-ing score. 2 Related Works … Websentence embeddings are computed.
