    "**Warning**: the latest TensorFlow versions are based on Keras 3. For previous chapters, it wasn't too hard to update the code to support Keras 3, but unfortunately it's much harder for this chapter: for example, stateful RNNs work very differently, ragged tensors are no longer supported, TensorFlow Hub models are no longer supported, and more. So for this chapter I've had to revert to Keras 2. To do that, I set the `TF_USE_LEGACY_KERAS` environment variable to `\"1\"` and import the `tf_keras` package. This ensures that `tf.keras` points to `tf_keras`, which is Keras 2.*."

    "This is a very basic implementation of beam search. I tried to make it readable and understandable, but it's definitely not optimized for speed! The function first uses the model to find the top _k_ words to start the translations (where _k_ is the beam width). For each of the top _k_ translations, it evaluates the conditional probabilities of all possible words it could add to that translation. These extended translations and their probabilities are added to the list of candidates. Once we've gone through all top _k_ translations and all words that could complete them, we keep only the top _k_ candidates with the highest probability, and we iterate over and over until they all finish with an EOS token. The top translation is then returned (after removing its EOS token).\n",

As we add more words, the probability gets smaller and smaller. To avoid the risk of it getting too small, which could cause floating point precision errors, the function keeps track of log probabilities instead of probabilities: recall that log(a\\*b) = log(a) + log(b), therefore log(p(S')) = log(p(S)) + log(p(W|S))."

    "1. Stateless RNNs can only capture patterns whose length is less than, or equal to, the size of the windows the RNN is trained on. Conversely, stateful RNNs can capture longer-term patterns. However, implementing a stateful RNN is much harder⁠—especially preparing the dataset properly. Moreover, stateful RNNs do not always work better, in part because consecutive batches are not independent and identically distributed (IID). Gradient Descent is not fond of non-IID datasets.\n",
    "2. In general, if you translate a sentence one word at a time, the result will be terrible. For example, the French sentence \"Je vous en prie\" means \"You are welcome,\" but if you translate it one word at a time, you get \"I you in pray.\" Huh? It is much better to read the whole sentence first and then translate it. A plain sequence-to-sequence RNN would start translating a sentence immediately after reading the first word, while an Encoder–Decoder RNN will first read the whole sentence and then translate it. That said, one could imagine a plain sequence-to-sequence RNN that would output silence whenever it is unsure about what to say next (just like human translators do when they must translate a live broadcast).\n",
    "3. Variable-length input sequences can be handled by padding the shorter sequences so that all sequences in a batch have the same length, and using masking to ensure the RNN ignores the padding token. For better performance, you may also want to create batches containing sequences of similar sizes. Ragged tensors can hold sequences of variable lengths, and Keras now supports them, which simplifies handling variable-length input sequences (at the time of this writing, it still does not handle ragged tensors as targets on the GPU, though). Regarding variable-length output sequences, if the length of the output sequence is known in advance (e.g., if you know that it is the same as the input sequence), then you just need to configure the loss function so that it ignores tokens that come after the end of the sequence. Similarly, the code that will use the model should ignore tokens beyond the end of the sequence. But generally the length of the output sequence is not known ahead of time, so the solution is to train the model so that it outputs an end-of-sequence token at the end of each sequence.\n",
    "4. Beam search is a technique used to improve the performance of a trained Encoder–Decoder model, for example in a neural machine translation system. The algorithm keeps track of a short list of the _k_ most promising output sentences (say, the top three), and at each decoder step it tries to extend them by one word; then it keeps only the _k_ most likely sentences. The parameter _k_ is called the _beam width_: the larger it is, the more CPU and RAM will be used, but also the more accurate the system will be. Instead of greedily choosing the most likely next word at each step to extend a single sentence, this technique allows the system to explore several promising sentences simultaneously. Moreover, this technique lends itself well to parallelization. You can implement beam search by writing a custom memory cell. Alternatively, TensorFlow Addons's seq2seq API provides an implementation.\n",
    "5. An attention mechanism is a technique initially used in Encoder–Decoder models to give the decoder more direct access to the input sequence, allowing it to deal with longer input sequences. At each decoder time step, the current decoder's state and the full output of the encoder are processed by an alignment model that outputs an alignment score for each input time step. This score indicates which part of the input is most relevant to the current decoder time step. The weighted sum of the encoder output (weighted by their alignment score) is then fed to the decoder, which produces the next decoder state and the output for this time step. The main benefit of using an attention mechanism is the fact that the Encoder–Decoder model can successfully process longer input sequences. Another benefit is that the alignment scores make the model easier to debug and interpret: for example, if the model makes a mistake, you can look at which part of the input it was paying attention to, and this can help diagnose the issue. An attention mechanism is also at the core of the Transformer architecture, in the Multi-Head Attention layers. See the next answer.\n",
    "6. The most important layer in the Transformer architecture is the Multi-Head Attention layer (the original Transformer architecture contains 18 of them, including 6 Masked Multi-Head Attention layers). It is at the core of language models such as BERT and GPT-2. Its purpose is to allow the model to identify which words are most aligned with each other, and then improve each word's representation using these contextual clues.\n",
    "7. Sampled softmax is used when training a classification model when there are many classes (e.g., thousands). It computes an approximation of the cross-entropy loss based on the logit predicted by the model for the correct class, and the predicted logits for a sample of incorrect words. This speeds up training considerably compared to computing the softmax over all logits and then estimating the cross-entropy loss. After training, the model can be used normally, using the regular softmax function to compute all the class probabilities based on all the logits."
