# Training Details |
|
|
|
## Training Data |
|
|
|
Falcon-Mamba has been trained with ~ 5,500 GT mainly coming from [Refined-Web](https://huggingface.co/datasets/tiiuae/falcon-refinedweb), a large volume web-only dataset filtered and deduplicated. |
|
Similar to the others [Falcon](https://huggingface.co/tiiuae/falcon-11B) suite models, Falcon-Mamba has been trained leveraging a multi-stage training strategy to increase the context-length training from 2,048 up to 8,192. |
|
Note that at inference the context-length is not relevant as the Mamba architecture has no limit on long range dependency. |
|
At the last training stage, small portion of high-quality curated data was used to further enhance performance. |
|
|
|
Overall, the data sources included RefinedWeb-English, high quality technical data, code data and conversational data extracted from public sources. |
|
In particular, we used samples coming from [Fineweb-edu](https://huggingface.co/datasets/HuggingFaceFW/fineweb-edu). |
|
|
|
The data was tokenized with the Falcon-[7B](https://huggingface.co/tiiuae/falcon-7B)/[11B](https://huggingface.co/tiiuae/falcon-11B) tokenizer. |
|
|
|
## Training Procedure |
|
Falcon-Mamba-7B was trained on 256 H100 80GB GPUs for the majority of the training, using a 3D parallelism strategy (TP=1, PP=1, DP=256) combined with ZeRO. |
|
|
|
### Training Hyperparameters |
|
|
|
| **Hyperparameter** | **Value** | **Comment** | |
|
|--------------------|------------|-------------------------------------------| |
|
| Precision | `bfloat16` | | |
|
| Optimizer | AdamW | | |
|
| Max learning rate | 6.4e-4 | Following a WSD (warmup-stable-decay) learning rate schedule | |
|
| Weight decay | 1e-1 | | |
|
| Batch size | 2048 | | |
|
|
|
|
|
The model was trained AdamW optimizer, WSD (warmup-stable-decay) learning rate schedule, and a batch size rampup from \\(b_{\mathrm{min}}=128\\) to \\(b_{\mathrm{max}}=2048\\) during first 50 GT of training. |
|
In the stable phase we used maximal learning rate \\(\eta_{\mathrm{max}}=6.4 \times 10^{-4}\\), and decayed it to the minimal value \\(\eta_{\mathrm{min}}=\frac{\eta_{\mathrm{max}}}{256}\\) with exponential schedule over 500 GT. |
|
Also, we applied *BatchScaling* during the rampup — rescaling learning rate \\(\eta\\) so that the Adam noise temperature \\(T_{\mathrm{noise}}\equiv\frac{\eta}{\sqrt{b}}\\) is kept constant. |
|
|
|
### Speeds, Sizes, Times |
|
|
|
The model training took roughly two months. |
|
|

# Evaluation |
|
|
|
## Benchmarks |
|
|
|
We evaluate our model on all benchmarks of the leaderboard's version 2 using the `lm-evaluation-harness` package, and we evaluate it on the benchmarks of version 1 using `lighteval`. |

This model can achieve comparable throughput and performance compared to other transformer based models that use optimized kernels such as Flash Attention 2. Make sure to install the optimized Mamba kernels with the following commands: |
|
|
|
```bash |
|
pip install "causal-conv1d>=1.4.0" mamba-ssm |
|
``` |
|
|
|
