Hoi hoe gaat het ermee? Wat kun je me vertellen over appels?<|im_end|>
<|im_start|>assistant
Hallo! Appels zijn zo'n heerlijk fruit. Ze komen in verschillende kleuren en smaken, zoals rode, witte, en goudbruine appels. Appels bevatten veel vezels en vitamines die goed zijn voor je gezondheid. Je kunt ze op verschillende manieren eten, bijvoorbeeld gesneden met wat kaneel of in een smoothie. Wil je meer weten over de voedingswaarde van appels of heb je interesse in andere fruitsoorten?<|im_end|>

Intended uses & limitations

As with all LLM's this model can also experience bias and hallucinations. Regardless of how you use this model always perform the necessary testing and validation.

The used dataset does not allow commercial usage.

Training and evaluation data

The training notebook is available at the following link: Qwen1_5_7B_Dutch_Chat_SFT

Training was performed with Google Colab PRO on a A100 - 40GB.

As the amount of data was more than would fit within the maximum 24 hour session that Google Colab PRO allows I split the dataset in 2 equal parts. Training for each part lasted around 14 hours. In the second part I enabled 'resume_from_checkpoint' to continue the training.

Training procedure

Training hyperparameters

The following hyperparameters were used during training:

learning_rate: 0.0003
train_batch_size: 2
eval_batch_size: 4
seed: 42
gradient_accumulation_steps: 32
total_train_batch_size: 64
optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: cosine
lr_scheduler_warmup_ratio: 0.05
training_steps: 1466
