|
16 |
+
```python
|
17 |
+
!pip install -qU transformers bitsandbytes accelerate
|
18 |
+
|
19 |
+
from transformers import AutoTokenizer
|

+
import transformers
|
21 |
+
import torch
|
22 |
+
|
23 |
+
model = "mlabonne/NeuralMix-2x7b"
|
24 |
+
|
25 |
+
tokenizer = AutoTokenizer.from_pretrained(model)
|
26 |
+
pipeline = transformers.pipeline(

model_kwargs={"torch_dtype": torch.float16, "load_in_4bit": True},
|
30 |
+
)
|
31 |
+
|
32 |
+
messages = [{"role": "user", "content": "Explain what a Mixture of Experts is in less than 100 words."}]
|
33 |
+
prompt = pipeline.tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
|
34 |
+
outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
|
35 |
+
print(outputs[0]["generated_text"])
|
36 |

A Mixture of Experts (ME) is a neural network architecture that allows for adaptive specialization of its hidden layers. It consists of an input layer, a mixture of expert layers with a set of hidden layers, and an output layer. The expert layers have different specializations and each one is responsible for predicting the output for a particular subset of the input data. The mixture of experts uses a gating network to dynamically select the expert layer that best fits the current input data. This adaptive approach can improve the performance and generalization capabilities of the neural network.

|
42 |
+
The Mixture of Experts model is particularly useful in situations where the data is complex, heterogeneous, or has varying structures. By enabling each expert to specialize in a particular type of input, the Mixture of Experts can learn to effectively handle diverse input data and provide more accurate predictions.
|
43 |
+
|
44 |
+
Overall, the Mixture of Experts can be seen as a type of neural network that combines the strengths of multiple models to create a more powerful and flexible predictive tool.
