- they all rely on ONE family of models Sequence Models.
The reason they matter is simple: most real-world data isn't independent. Words depend on the words before them. Stock prices depend on yesterday. A pedestrian's next step depends on their last three. Traditional ML assumes i.i.d. data, and that assumption breaks the moment order matters.
📖 In this article,
AIML.com breaks down everything you need to know:
🔹 What sequence models are & why order in data matters
🔹 Why traditional ML fails on sequential, non-i.i.d. data
🔹 RNNs: the foundation, and their vanishing gradient flaw
🔹 LSTMs: how memory cells solve long-range dependencies
🔹 GRUs: a leaner, faster cousin of LSTMs
🔹 Transformers: self-attention powering BERT, GPT & more
🔹 9 real-world applications across industries
💬 Interview tip: This question is a staple in NLP, Deep Learning, and Generative AI interviews. Interviewers use it because it tests three things in one shot: your grasp of the RNN → LSTM → GRU → Transformer evolution, the 𝘸𝘩𝘺 behind each leap, and your ability to map theory to real products.
