The name of the model is a homage to Fela Kuti's song Mr Grammarticalogy-Lisationalsim Is The Boss released on the B-side of his 1976 LP Excuse O.

It is a 16/32 QLoRa all linear layers finetune of teknium/OpenHermes-2.5-Mistral-7B using controlled natural language (CNL) phrases generated from the September 23rd release of SNOMED CT United States Edition. The general idea is described in Domain-Specific Biomedical Ontologies, RALM, and Generative Medical Expert Systems.

It is an experimental model for non-production environments to test how generative AI systems can be trained for use in various medical informatics scenarios.

The original model was converted to MLX format, quantized, and then subject to continued pretraining using all the active domain-expert text definitions available in SNOMED-CT at a constant learning rate of 1e-5 using mlx_lm's LoRa finetuning functionality with 16 LoRa layers.

It was then trained on a dataset of 336,762 records of medical terminology definition instructions generated from SNOMED-CT using a fork of django-snomed-ct. These definition instructions were generated from the disorder, finding, morphological abnormality, and situation hierarchies in SNOMED-CT. This training step was done using mlx-tuning-fork through 42,096 training iterations, with a batch size of 8 at a time, using LoRa on all linear layers.

There were 51,082 records of more granular definition instructions, part of which were incorporated into the training dataset. However, 40% were kept aside for validation.

Prompt: <|im_start|>system
Give detailed responses.  Use critical thinking and think step-by-step.
Don't make up answers if you don't know. Use SNOMED-CT definitions as much as possible, describing 
characterizations in form of morphological abnormalities involved in diagnoses (their signs), their etiology (causes/basis),  
their related findings. 
## Question ##
What are the signs and etiology of Skin ulcer due to diabetes mellitus?

## Answer ##
SNOMED-CT defines Skin ulcer due to diabetes mellitus as characterized in form by an ulcer located in a skin structure.  
Ulcer is a mophologic abnormality.  
The cause or origin of a disorder is part of its etiology. 
Skin ulcer due to diabetes mellitus is caused by diabetes mellitus.  
So, the etiology of Skin ulcer due to diabetes mellitus is diabetes mellitus.
   
Infected ulcer of skin is an infectious process characterized in form by an ulcer located in a skin structure. 
Since the signs of Skin ulcer due to diabetes mellitus is also an ulcer, Infected ulcer of skin is 
an example of a disorder with the same signs as Skin ulcer due to diabetes mellitus.

## Question ##
The patient has Irritable bowel syndrome.
Summarize the the biological processes and signs (characterizations in form)
involved in the patient's diagnoses. Give examples of other disorders with the same signs and etiology.

Irritable bowel syndrome (SNOMED-CT definition: Irritable bowel syndrome) is a functional disorder of the gastrointestinal tract, characterized in form by abnormal bowel movements. It is a clinical diagnosis, and its signs and symptoms include abdominal pain, bloating, and altered bowel movements (diarrhea, constipation, or both).

Etiology: Irritable bowel syndrome is believed to be caused by factors including abnormal gut motility, gastrointestinal dysrhythmias, and psychological factors.

Signs: Examples of signs of the disorder include changes in stool consistency and abdominal pain.

Irritable bowel syndrome is a functional bowel disorder, which is a category of gastrointestinal disorders with similar signs and symptoms. Examples of disorders with the same signs and etiology include:

1. Functional dyspepsia: It is characterized by an upper abdominal pain or discomfort and has a similar etiology as irritable bowel syndrome. It is a functional disorder of the stomach and small intestine, and its signs include epigastric pain and discomfort.

2. Chronic idiopathic constipation: It is characterized by chronic constipation and has a similar etiology as irritable bowel syndrome. It is a functional disorder of the colon
