+# GPTSAN-japanese
+
+## Overview
+
+The GPTSAN-japanese model was released in the repository by Toshiyuki Sakamoto (tanreinama).
+
+GPTSAN is a Japanese language model using Switch Transformer. It has the same structure as the model introduced as Prefix LM
+in the T5 paper, and support both Text Generation and Masked Language Modeling tasks. These basic tasks similarly can
+fine-tune for translation or summarization.
+
+### Generation
+
+The `generate()` method can be used to generate text using GPTSAN-Japanese model.
+
+```python
+>>> from transformers import AutoModel, AutoTokenizer
+>>> import torch
+
+>>> tokenizer = AutoTokenizer.from_pretrained("Tanrei/GPTSAN-japanese")
+>>> model = AutoModel.from_pretrained("Tanrei/GPTSAN-japanese").cuda()
+>>> x_tok = tokenizer("は、", prefix_text="織田信長", return_tensors="pt")
+>>> torch.manual_seed(0)
+>>> gen_tok = model.generate(x_tok.input_ids.cuda(), token_type_ids=x_tok.token_type_ids.cuda(), max_new_tokens=20)
+>>> tokenizer.decode(gen_tok[0])
+'織田信長は、2004年に『戦国BASARA』のために、豊臣秀吉'
+```
+
+## GPTSAN Features
+
+GPTSAN has some unique features. It has a model structure of Prefix-LM. It works as a shifted Masked Language Model for Prefix Input tokens. Un-prefixed inputs behave like normal generative models.
+The Spout vector is a GPTSAN specific input. Spout is pre-trained with random inputs, but you can specify a class of text or an arbitrary vector during fine-tuning. This allows you to indicate the tendency of the generated text.
+GPTSAN has a sparse Feed Forward based on Switch-Transformer. You can also add other layers and train them partially. See the original GPTSAN repository for details.
+
+### Prefix-LM Model
+
+GPTSAN has the structure of the model named Prefix-LM in the `T5` paper. (The original GPTSAN repository calls it `hybrid`)
+In GPTSAN, the `Prefix` part of Prefix-LM, that is, the input position that can be referenced by both tokens, can be specified with any length.
+Arbitrary lengths can also be specified differently for each batch.
+This length applies to the text entered in `prefix_text` for the tokenizer.
+The tokenizer returns the mask of the `Prefix` part of Prefix-LM as `token_type_ids`.
+The model treats the part where `token_type_ids` is 1 as a `Prefix` part, that is, the input can refer to both tokens before and after.
+
+Tips:
+
+Specifying the Prefix part is done with a mask passed to self-attention.
+When token_type_ids=None or all zero, it is equivalent to regular causal mask
+
+for example:
+
+>>> x_token = tokenizer("ｱｲｳｴ")
+input_ids:      | SOT | SEG | ｱ | ｲ | ｳ | ｴ |
+token_type_ids: | 1   | 0   | 0 | 0 | 0 | 0 |
+prefix_lm_mask:
+SOT | 1 0 0 0 0 0 |
+SEG | 1 1 0 0 0 0 |
+ｱ   | 1 1 1 0 0 0 |
+ｲ   | 1 1 1 1 0 0 |
+ｳ   | 1 1 1 1 1 0 |
+ｴ   | 1 1 1 1 1 1 |
+
+>>> x_token = tokenizer("", prefix_text="ｱｲｳｴ")
+input_ids:      | SOT | ｱ | ｲ | ｳ | ｴ | SEG |
+token_type_ids: | 1   | 1 | 1 | 1 | 1 | 0  |
+prefix_lm_mask:
+SOT | 1 1 1 1 1 0 |
+ｱ   | 1 1 1 1 1 0 |
+ｲ   | 1 1 1 1 1 0 |
+ｳ   | 1 1 1 1 1 0 |
+ｴ   | 1 1 1 1 1 0 |
+SEG | 1 1 1 1 1 1 |
+
+>>> x_token = tokenizer("ｳｴ", prefix_text="ｱｲ")
+input_ids:      | SOT | ｱ | ｲ | SEG | ｳ | ｴ |
+token_type_ids: | 1   | 1 | 1 | 0   | 0 | 0 |
+prefix_lm_mask:
+SOT | 1 1 1 0 0 0 |
+ｱ   | 1 1 1 0 0 0 |
+ｲ   | 1 1 1 0 0 0 |
+SEG | 1 1 1 1 0 0 |
+ｳ   | 1 1 1 1 1 0 |
+ｴ   | 1 1 1 1 1 1 |
+
+### Spout Vector
+
+A Spout Vector is a special vector for controlling text generation.
+This vector is treated as the first embedding in self-attention to bring extraneous attention to the generated tokens.
+In the pre-trained model published from `Tanrei/GPTSAN-japanese`, the Spout Vector is a 128-dimensional vector that passes through 8 fully connected layers in the model and is projected into the space acting as external attention.
+The Spout Vector projected by the fully connected layer is split to be passed to all self-attentions.
