# Model Summary |
|
<img src="Damysus.png" width="500" alt="Damysus - the fastest giant"/> |
|
|
|
<!-- Provide a quick summary of what the model is/does. --> |
|
This model is a instruction-tuned version of Phi-2, a Transformer model with 2.7 billion parameters from Microsoft. |
|
The model has undergone further training to better follow specific user instructions, enhancing its ability to perform tasks as directed and improve its interaction with users. |
|
This additional training helps the model to understand context better, generate more accurate and relevant responses, and adapt to a wide range of language-based tasks such as: |
|
- Questions and Answers, |
|
- Data Extraction, |
|
- Structured Outputs (i.e., JSON outputs), |
|
- And providing explanations, |
|
|
|
## Model Description |
|
|
|
<!-- Provide a longer summary of what this model is. --> |
|
This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated. |
|
|
|
- **Developed by:** [Prince Canuma](https://huggingface.co/prince-canuma) |
|
- **Model type:** Transformer |
|
- **License:** MIT |
|
- **Finetuned from model:** microsoft/phi-2 |
|
|
|
|
|
## Uses |
|
|
|
<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. --> |
|
|
|
### Direct Use |
|
|
|
<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. --> |
|
|
|
You can use this model to build local/cloud RAG applications. |
|
It can serve as the: |
|
- Answer synthesizer, |
|
- Summarizer |
|
- Or query rewriter model. |
|
|
|
### Limitations |
|
|
|
This model inherits some of the base model's limitations, such as: |
|
- Generate Inaccurate Code and Facts: The model may produce incorrect code snippets and statements. Users should treat these outputs as suggestions or starting points, not as definitive or accurate solutions. |
|
- Limited Scope for code: Majority of Phi-2 training data is based in Python and use common packages such as "typing, math, random, collections, datetime, itertools". If the model generates Python scripts that utilize other packages or scripts in other languages, we strongly recommend users manually verify all API uses. |
|
- Language Limitations: The model is primarily designed to understand standard English. Informal English, slang, or any other languages might pose challenges to its comprehension, leading to potential misinterpretations or errors in response. |
|
|
|
## How to Get Started with the Model |
|
|
|
Use the code below to get started with the model. |
|
|
|
```python |
|
from transformers import pipeline, Conversation |
|
|
|
chatbot = pipeline("conversational", model="prince-canuma/Damysus-2.7B-Chat") |
|
conversation = Conversation("I'm looking for a movie - what's your favourite one?") |
|
output = chatbot(conversation) |
|
|
|
print(output) |
|
``` |
|
|
|
Or you can instatiate the model and tokenizer directly |
|
```python |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("prince-canuma/Damysus-2.7B-Chat") |
|
model = AutoModelForCausalLM.from_pretrained("prince-canuma/Damysus-2.7B-Chat") |
|
|
|
inputs = tokenizer.apply_chat_template( |
|
[ |
|
{"content":"You are an helpful AI assistant","role":"system"}, |
|
{"content":"I'm looking for a movie - what's your favourite one?","role":"user"}, |
|
], add_generation_prompt=True, return_tensors="pt", |
|
).to("cuda") |
|
|
|
outputs = model.generate(inputs, do_sample=False, max_new_tokens=256) |
|
|
|
input_length = inputs.shape[1] |
|
print(tokenizer.batch_decode(outputs[:, input_length:], skip_special_tokens=True)[0]) |
|
``` |
|
|
|
Output: |
|
```shell |
|
My favorite movie is "The Shawshank Redemption." |
|
|
|
It's a powerful and inspiring story about hope, friendship, and redemption. |
|
The performances by Tim Robbins and Morgan Freeman are exceptional, |
|
and the film's themes and messages are timeless. |
|
|
|
I highly recommend it to anyone who enjoys a well-crafted and emotionally engaging story. |
|
``` |
|
|
|
### Structured Output |
|
```python |
|
from transformers import AutoTokenizer, AutoModelForCausalLM |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("prince-canuma/Damysus-2.7B-Chat") |
|
model = AutoModelForCausalLM.from_pretrained("prince-canuma/Damysus-2.7B-Chat") |
|
|
|
inputs = tokenizer.apply_chat_template( |
|
[ |
|
{"content":"You are a Robot that ONLY outputs JSON. Use this structure: {'entities': [{'type':..., 'name':...}]}.","role":"system"}, |
|
{"content":""""Extract the entities of type 'technology' and 'file_type' in JSON format from the following passage: AI is a transformative |
|

Optical Character Recognition (OCR) to understand, interpret, and summarize text. These technologies enhance accuracy, |
|

## Training Details |
|
|
|
### Training Data |
|
|
|
<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. --> |
|
I used [SlimOrca](https://huggingface.co/datasets/Open-Orca/SlimOrca) dataset, a new curated subset of our OpenOrca data. |
|
In the course of this study, the [SlimOrca](https://huggingface.co/datasets/Open-Orca/SlimOrca) dataset was used, representing a meticulously curated subset derived from the broader OpenOrca dataset. This release provides an efficient means of reaching performance on-par with using larger slices of the [OpenOrca](https://huggingface.co/datasets/Open-Orca/OpenOrca), while only including ~500k GPT-4 completions. |
|
|
|
|
|
Subsequently, two distinct subsets were crafted, comprising 102,000 and 1,000 samples, denoted as: |
|
|
|
- [prince-canuma/SmallOrca](https://huggingface.co/datasets/prince-canuma/SmallOrca) |
|
- [prince-canuma/TinyOrca](https://huggingface.co/datasets/prince-canuma/TinyOrca) |
|
|
|
Although experimentation was conducted with both datasets, optimal results were achieved through fine-tuning on a modest set of 200 samples. |
|
Notably, the investigation revealed that augmenting the training data beyond this threshold predominantly enhanced the model's proficiency in generating Chain-of-Thought responses. |
|
However, it is imperative to note that the preference for Chain-of-Thought responses may not be universally applicable. Particularly in scenarios like the RAG setup, |
|
succinct answers to prompts are often favored, especially for straightforward queries. |
|
|
|
### Training Procedure |
|
|
|
<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. --> |
|
[TODO] |
|
|
|
#### Preprocessing |
|
|
|
1. Convert dataset to chatML format |
|
2. Remove all samples with more than 2048 tokens (Phi-2 context size) |
|
3. Mask instructions (System and User) at training time. |
|
|
|
|
|
#### Training Hyperparameters |
|
|
|
- **Training regime:** bf16 mixed precision <!--fp32, fp16 mixed precision, bf16 mixed precision, bf16 non-mixed precision, fp16 non-mixed precision, fp8 mixed precision --> |
|
|
|
[TODO] |
|
|
|
## Evaluation |
|
|
|
<!-- This section describes the evaluation protocols and provides the results. --> |
|
|
|
We evaluate models on 7 key benchmarks using the Eleuther AI Language Model Evaluation Harness , a unified framework to test generative language models on a large number of different evaluation tasks. |
|
|
|
- AI2 Reasoning Challenge (25-shot) - a set of grade-school science questions. |
|
- HellaSwag (10-shot) - a test of commonsense inference, which is easy for humans (~95%) but challenging for SOTA models. |
|
- MMLU (5-shot) - a test to measure a text model's multitask accuracy. The test covers 57 tasks including elementary mathematics, US history, computer science, law, and more. |
|
- TruthfulQA (0-shot) - a test to measure a model's propensity to reproduce falsehoods commonly found online. Note: TruthfulQA is technically a 6-shot task in the Harness because each example is prepended with 6 Q/A pairs, even in the 0-shot setting. |
|
- Winogrande (5-shot) - an adversarial and difficult Winograd benchmark at scale, for commonsense reasoning. |
|
- GSM8k (5-shot) - diverse grade school math word problems to measure a model's ability to solve multi-step mathematical reasoning problems. |
|
For all these evaluations, a higher score is a better score. We chose these benchmarks as they test a variety of reasoning and general knowledge across a wide variety of fields in 0-shot and few-shot settings. |
