+# Russian hwu64
+
+This is a text classification dataset. It is intended for machine learning research and experimentation.
+
+This dataset is obtained via formatting another publicly available data to be compatible with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html).
+
+## Usage
+
+It is intended to be used with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html):
+
+```python
+from autointent import Dataset
+
+dream = Dataset.from_datasets("AutoIntent/hwu64_ru")
+```
+
+## Source
+
+This dataset is taken from private github repository `LadaNikitina/ruHWU64` and formatted with our [AutoIntent Library](https://deeppavlov.github.io/AutoIntent/index.html):
+
+```python
+from datasets import load_from_disk
+from autointent import Dataset
+
+def convert_ruhwu64(hwu64_train):
+    intent_names = sorted(hwu64_train.unique("intent"))
+    name_to_id = dict(zip(intent_names, range(len(intent_names)), strict=False))
+    n_classes = len(intent_names)
+
+    classwise_utterance_records = [[] for _ in range(n_classes)]
+    intents = [
+        {
+            "id": i,
+            "name": name,
+        }
+        for i, name in enumerate(intent_names)
+    ]
+
+    for batch in hwu64_train.iter(batch_size=16, drop_last_batch=False):
+        for txt, name in zip(batch["text"], batch["intent"], strict=False):
+            intent_id = name_to_id[name]
+            target_list = classwise_utterance_records[intent_id]
+            target_list.append({"utterance": txt, "label": intent_id})
+
+    utterances = [rec for lst in classwise_utterance_records for rec in lst]
+    return Dataset.from_dict({"intents": intents, "train": utterances})
+
