About the Natural Language Processing Professional certification
A professional-grade certification covering the full arc of modern Natural Language Processing. You will reason precisely about text preprocessing (normalization, stemming, lemmatization, stopword handling) and tokenization (word, subword, BPE, WordPiece); represent text with bag-of-words, n-grams, and TF-IDF; build and interpret word embeddings (word2vec CBOW and skip-gram, GloVe, and contextual embeddings); understand language modeling and perplexity; trace sequence models (RNN, LSTM) and the attention mechanism through to the transformer at an introductory level; distinguish encoder, decoder, and encoder-decoder architectures; and apply NLP to core tasks — text classification, sentiment analysis, named-entity recognition, part-of-speech tagging, machine translation, summarization, and question answering. The exam tests deliberate, current understanding of evaluation (accuracy, F1, BLEU, ROUGE, perplexity), the modern pretrained-model pipeline (pretrain, fine-tune, prompt), and the common pitfalls that derail real NLP systems — at the level expected of an engineer who ships language applications in production.
What you will learn
The official Natural Language Processing Professional study course covers:
- From Raw Text to Tokens — Preprocessing, normalization, stemming vs lemmatization, stopwords, and the tokenization spectrum from words to subwords (BPE, WordPiece).
- Tokenization Deep-Dive — The word vs subword vs character spectrum, how BPE and WordPiece build vocabularies, and how tokens become embeddings.
- Representing Meaning — Bag-of-words, n-grams, TF-IDF, and the leap to dense word embeddings: word2vec (CBOW/skip-gram), GloVe, and contextual embeddings.
- Sequences, Attention, and the Transformer — RNN/LSTM for NLP, the attention mechanism, encoder-decoder seq2seq with attention, and the transformer block at an intro level.
- Tasks, Evaluation, and Pitfalls — Core NLP tasks, the metrics that score them (accuracy/F1, BLEU, ROUGE, perplexity), the pretrained-model pipeline, and the pitfalls that derail real…
- Hands-on Lab — From Tokens to a Working NLP Model — An NLP capstone in Google Colab: turn raw text into tokens, build a strong TF-IDF baseline, compare it with a subword tokenizer and contextual embedd…
