## Introduction
With a few additional lines of code, (traditional) **logging** supports tracking loss, hyperparameters, etc., providing _basic_ insights for users'
AI/ML experiments. But...can we also enable _in-depth understanding of large-scale training data_, the most important ingredient in
AI/ML, with a similar logging interface? Try out LogIX that is built upon our cutting-edge data valuation/attribution research (Support
[Huggingface Transformers](https://github.com/logix-project/logix/tree/main?tab=readme-ov-file#huggingface-integration) and
[PyTorch Lightning](https://github.com/logix-project/logix/tree/main?tab=readme-ov-file#pytorch-lightning-integration) integrations)!

- **PyPI**
```bash
pip install logix-ai
```

- **From source** (Latest, recommended)
```bash
git clone https://github.com/logix-project/logix.git
cd logix
pip install -e .
```

## Easy to Integrate

Our software design allows for the seamless integration with popular high-level frameworks including
[HuggingFace Transformer](https://github.com/huggingface/transformers/tree/main) and
[PyTorch Lightning](https://github.com/Lightning-AI/pytorch-lightning), that conveniently handles
distributed training, data loading, etc. Advanced users, who don't use high-level frameworks, can
still integrate LogIX into their existing training code similarly to any traditional logging software
(See our [Tutorial](https://github.com/logix-project/logix/tree/main?tab=readme-ov-file#getting-started)).

### 🤗 HuggingFace Integration

A full example can be found [here](https://github.com/logix-project/logix/tree/main/examples/huggingface).

```python
from transformers import Trainer, Seq2SeqTrainer
from logix.huggingface import patch_trainer, LogIXArguments

# Define LogIX arguments
logix_args = LogIXArguments(project="myproject",
                            config="config.yaml",
                            lora=True,
                            hessian="raw",
                            save="grad")

# Patch HF Trainer
LogIXTrainer = patch_trainer(Trainer)

# Pass LogIXArguments as TrainingArguments
trainer = LogIXTrainer(logix_args=logix_args,
                       model=model,
                       train_dataset=train_dataset,
                       *args,
                       **kwargs)

# Instead of trainer.train(), use
trainer.extract_log()
trainer.influence()
trainer.self_influence()
```

### ⚡ PyTorch Lightning Integration

A full example can be found [here](https://github.com/logix-project/logix/tree/main/examples/lightning).

```python
from lightning import LightningModule, Trainer
from logix.lightning import patch, LogIXArguments

class MyLitModule(LightningModule):
    ...

def data_id_extractor(batch):
    return tokenizer.batch_decode(batch["input_ids"])

# Define LogIX arguments
logix_args = LogIXArguments(project="myproject",
                            config="config.yaml",
                            lora=True,
                            hessian="raw",
                            save="grad")

# Patch Lightning Module and Trainer
LogIXModule, LogIXTrainer = patch(MyLitModule,
                                  Trainer,
                                  logix_args=logix_args,
                                  data_id_extractor=data_id_extractor)

# Use patched Module and Trainer as before
module = LogIXModule(user_args)
trainer = LogIXTrainer(user_args)

# Instead of trainer.fit(module, train_loader), use
trainer.extract_log(module, train_loader)
trainer.influence(module, train_loader)
```

## Getting Started
### Logging
Training log extraction with LogIX is as simple as adding one `with` statement to the existing
training code. LogIX automatically extracts user-specified logs using PyTorch hooks, and stores
it as a tuple of `([data_ids], log[module_name][log_type])`. If needed, LogIX writes these logs
to disk efficiently with memory-mapped files.

```python
import logix

# Initialze LogIX
run = logix.init(project="my_project")

# Specify modules to be tracked for logging
run.watch(model, name_filter=["mlp"], type_filter=[nn.Linear])

# Specify plugins to be used in logging
run.setup({"grad": ["log", "covariance"]})
run.save(True)

for batch in data_loader:
    # Set `data_id` (and optionally `mask`) for the current batch 
    with run(data_id=batch["input_ids"], mask=batch["attention_mask"]):
        model.zero_grad()
        loss = model(batch)
        loss.backward()
# Synchronize statistics (e.g. covariance) and write logs to disk
run.finalize()
```

### Training Data Attribution
As a part of our initial research, we implemented influence functions using LogIX. We plan to provide more
pre-implemented interpretability algorithms if there is a demand.

```python
# Build PyTorch DataLoader from saved log data
log_loader = run.build_log_dataloader()

with run(data_id=test_batch["input_ids"]):
    test_loss = model(test_batch)
    test_loss.backward()

test_log = run.get_log()
run.influence.compute_influence_all(test_log, log_loader) # Data attribution
run.influence.compute_self_influence(test_log) # Uncertainty estimation
```

Please check out [Examples](/examples) for more detailed examples!

## Features
Logs from neural networks are difficult to handle due to the large size. For example,
the size of the gradient of *each* training datapoint is about as large as the whole model. Therefore,
we provide various systems support to efficiently scale neural network analysis to
billion-scale models. Below are a few features that LogIX currently supports:

- **Gradient compression** (compression ratio: 1,000-100,000x)
- **Memory-map-based data IO**
- **CPU offloading of statistics**
