Ujamaa XGB Model

Model Description

The Ujamaa XGB Model is part of the Soulprint Archetype Framework, built to predict the Ujamaa score (0.0–1.0) of text.
Ujamaa embodies collaborative power and collective uplift, rooted in teamwork, shared responsibility, and mutual aid.

Archetype Adjective: Collaborative
Catchphrase: Nobody left behind.
Perspective: Shared power is true power.
Symbolic Inspirations: Ella Baker, Black women behind the scenes

Intended Uses

Assess narrative alignment with Ujamaa’s collaborative qualities
Support AI agents in cultural grounding
Enhance story-based AI and reflective tools

Training & Evaluation

Algorithm: XGBoo

Ujamaa XGB Model

Overview

The Ujamaa XGB Model is part of the Soulprint Archetype Framework, designed to estimate a continuous "Ujamaa score" (0.0–1.0) from text.
Ujamaa represents the archetype of collaborative strength and collective uplift—rooted in principles of cooperation, mutual aid, and shared responsibility.

This model was trained using XGBoost regression on sentence embeddings generated with all-mpnet-base-v2. The outputs represent how strongly a piece of text reflects Ujamaa’s collaborative essence.

Training & Evaluation

The model was trained with 5-fold cross-validation to ensure generalization.

Fold Performance

📂 Fold 1: MSE = 0.0277, R² = 0.6063
📂 Fold 2: MSE = 0.0271, R² = 0.6416
📂 Fold 3: MSE = 0.0264, R² = 0.6116
📂 Fold 4: MSE = 0.0273, R² = 0.6351
📂 Fold 5: MSE = 0.0289, R² = 0.6100

Cross-Validation Summary

📊 Mean MSE: 0.0275 ± 0.0008
📊 Mean R²: 0.6209 ± 0.0145

✅ Final model retrained on full dataset and saved as Ujamaa_xgb_model.json

Usage

You can load the model directly from Hugging Face Hub (replace with your repo ID once pushed):

python

import xgboost as xgb
from sentence_transformers import SentenceTransformer
from huggingface_hub import hf_hub_download

# -----------------------------
# 1. Download model from Hugging Face Hub
# -----------------------------
REPO_ID = "mjpsm/Ujamaa-xgb-model"
FILENAME = "Ujamaa_xgb_model.json"

model_path = hf_hub_download(repo_id=REPO_ID, filename=FILENAME)

# -----------------------------
# 2. Load model + embedder
# -----------------------------
model = xgb.XGBRegressor()
model.load_model(model_path)

embedder = SentenceTransformer("all-mpnet-base-v2")

# -----------------------------
# 3. Example prediction
# -----------------------------
text = "We organized food drives together, making sure every family had what they needed."
embedding = embedder.encode([text])
score = model.predict(embedding)[0]

print("Predicted Ujamaa Score:", round(float(score), 3))

Intended Use

Primary Use Case: Evaluate how strongly text aligns with the Ujamaa archetype (collaboration, teamwork, mutual uplift).
Applications:
Narrative analysis in community and cultural contexts
AI-driven reflection tools for cooperative leadership
Enhancing RAG agents and story-based AI with archetypal grounding

Limitations

The model reflects patterns learned from synthetic + curated data and may not generalize perfectly to all real-world contexts.
Scores are continuous signals (0.0–1.0), not binary labels. Thresholds should be set depending on application.
Archetype interpretations are cultural and symbolic, not universal truth markers.
