Deep Learning Techniques in NLP: Embeddings and Neural Networks
🚀 Deep Learning in NLP: Word Embeddings & Neural Networks
Deep learning revolutionized NLP through the use of word embeddings and neural networks, bringing semantic understanding closer to human-level performance.
🧠 Word Embeddings
Techniques like:
- 🔤 Word2Vec
- 🧮 GloVe
- 🔡 FastText
convert words into dense vectors that capture semantic relationships such as similarity and contextual nuance.
These embeddings allow models to:
- Recognize word similarity (e.g., king ≈ queen)
- Understand relationships (e.g., Paris - France ≈ Berlin - Germany)
🤖 Neural Networks for NLP
Modern neural architectures, especially transformer-based models, process these embeddings to perform tasks like:
- 🌍 Translation
- 📄 Summarization
- 📊 Classification
💻 Example: Using Word2Vec in Python
from gensim.models import Word2Vec
sentences = [['natural', 'language', 'processing'], ['machine', 'learning', 'is', 'fun']]
model = Word2Vec(sentences, vector_size=100, window=5, min_count=1, workers=4)
print(model.wv['language'])
🔍 Why It Matters
This approach enables models to leverage contextual semantics, making NLP systems more human-like and accurate.
