mjpsm / Skill-Level-XGB-v2

Skill Level Classifier (XGBoost, v2)

What it does: Predicts an entrepreneur’s skill level — Low , Medium , or High — from eight 1–10 numeric features.
Why it’s here: Compact, fast, and easy to deploy for tabular inference. Trained with early stopping; no target leakage.

Files in this repo

• xgb_model_Skill_Level_v2.json — trained XGBoost model
• feature_order_Skill_Level_v2.json — list of feature names (order-sensitive)
• label_map_Skill_Level_v2.json — mapping from class name → index (don’t assume order)

Input features (1–10 scale)

All inputs are integers or floats in the range 1–10.

• years_experience_score
• education_training_score
• execution_ability_score
• problem_solving_score
• confidence_score
• idea_difficulty_score
• leadership_score
• networking_score

Feature definitions (what 1, 5, 10 roughly mean)

• years_experience_score — Practical experience in entrepreneurial, business, or technical work.
  1: none · 5: ~3–4 years/moderate exposure · 10: 10+ years/expert-level track record

• education_training_score — Formal or informal training related to business/entrepreneurship/tech.
  1: no training · 5: some courses/undergrad/bootcamps · 10: advanced degrees/certifications/ongoing education

• execution_ability_score — Ability to independently complete tasks and ship projects.
  1: needs step-by-step guidance · 5: handles medium complexity with minimal help · 10: ships complex projects reliably, end-to-end

• problem_solving_score — Adaptability and effectiveness at diagnosing/solving issues.
  1: gets stuck frequently · 5: resolves common issues with some effort · 10: quickly solves complex/novel problems

• confidence_score — Self-efficacy and decisiveness applying skills in practice.
  1: not confident · 5: moderately confident · 10: highly confident and decisive under uncertainty

• idea_difficulty_score — Complexity/ambition of the current venture or idea.
  1: very simple/small scope · 5: moderate (e.g., niche app) · 10: highly complex (e.g., AI/biotech/multi-sided marketplace)

• leadership_score — Experience leading people, projects, or cross-functional efforts.
  1: no leadership experience · 5: led small teams/projects · 10: extensive leadership of large/complex teams

• networking_score — Ability to leverage mentors, partnerships, and resources/funding.
  1: minimal network/isolated · 5: active connections and events · 10: strong network; partnerships/fundraising proficiency

Note: The dataset also contains a skill_level_readiness (1–10) field, but it is not used as an input in this v2 model to avoid target leakage.
