What is embedding NLP?
In natural language processing (NLP), word embedding is a term used for the representation of words for text analysis, typically in the form of a real-valued vector that encodes the meaning of the word such that the words that are closer in the vector space are expected to be similar in meaning.

How is one hot encoding used in NLP?
As mentioned in the previous section, traditional NLP often uses one-hot encoding to represent the word in a fixed vocabulary and uses a BoW to represent documents. Such an approach treats each word as, for example, house, road, tree, as an atomic symbol. The one-hot encoding will generate representations like [0 0 0 0 0 0 0 0 0 0 1 0 0 0 0].
How are encoders and transformers used in NLP?
Both the encoding models are designed to be as general-purpose as possible. This is accomplished by using multi-task learning whereby a single encoding model is used to feed multiple downstream tasks. This uses the transformer architecture which creates context-aware representations for every token.
Why is NLP is perfect for machine learning?
The effectiveness and scalability of the representation largely determine for the performance of the downstream machine learning model and application. As mentioned in the previous section, traditional NLP often uses one-hot encoding to represent the word in a fixed vocabulary and uses a BoW to represent documents.
Which is the correct way to represent a word in NLP?
As mentioned in the previous section, traditional NLP often uses one-hot encoding to represent the word in a fixed vocabulary and uses a BoW to represent documents. Such an approach treats each word as, for example, house, road, tree, as an atomic symbol.
