The science of Neufast Patent-pending Debiased AI
Our mission is to provide you and your candidates with engaging and highly accurate recruitment without bias. We ensure our scores are always valid, reliable, and fair by our deeply scientific, multi-layered Debiased AI/ML model.
Visual, Audio and Textual Based Analysis
Candidate’s apparent features, prosody features and semantic features are extracted from his/her videos based on computer vision, speech recognition and natural language processing techniques.
Visual channel for apparent feature extraction
Apparent features such as facial expression and gesture are implicitly extracted by computer vision technique.
Audio channel for prosody feature extraction
Prosody features such as tonality, pace and rhythm are implicitly extracted by audio analysis technique
Textual channel for semantic feature extraction
The syntactic and semantic meaning of candidate’s spoken texts are extracted by natural language processing technique with contextual awareness
Neufast Patent-pending Debiased AI
Model Architecture
Our Patent-pending Debiased AI model analyzes the audiovisual and semantic features in a comprehensive way with complex task-oriented adaptive weighting scheme to infer candidate’s Impression Score and Potential Work Performance Score.

Internal Governance of Developing Ethical AI Model
Neufast embraces Ethical AI and data ethics in the operation, the development and the application of AI following Ethics Guidelines for Trustworthy AI published by the European Commission in December 2018 [1]. To ensure the ethical development and use of AI in Recruiting, the data annotation and AI model development process of Neufast follows the 7 Ethical Principles of AI for internal data governance: 1. Accountability, 2. Human Oversight, 3. Transparency and Interpretability, 4. Data Privacy, 5. Fairness, 6. Beneficial AI, and 7. Reliability, Robustness and Security [2]. Decisions made by Neufast's patent-pending Debiased AI are EXPLAINABLE, TRANSPARENT & FAIR as Personal Identifiable Information (PII) are redacted. Neufast's patent-pending Debiased AI systems are designed to be HUMAN-CENTRIC [3].
-
No manipulation of the training data collection leading to a biased model in favor of some certain group
-
No data preprocessing that changes the data distributions for different groups
Data Preparation
-
All key aspects of the model building process are reviewed
-
Salient numerical results are copied into the sheet
-
All significant deviations from the standard model training process are well documented
Model Building &
Training
-
Adverse Impact Assessment is done to evaluate if our trained AI model complies with the UGESP's four-fifth rule* with respect to different groups in either: Demography, Educational background or other groups defined by clients

Assessment of Impression performance
Neufast’s patent-pending Debiased AI video assessment tool assesses candidate’s capability in making a positive impression on others through three perspectives:
Composure
Self-confidence
Positive emotions
Assessment of Motivation
Neufast’s Debiased AI video assessment tool identifies candidate's motivation to initiate work-related behaviors for person-job fit & talent retention.
Assessment of
Work Performance
Neufast’s competency model is built from cumulated studies on work performance. Candidates will be assessed through their task, contextual and adaptive performance.
Comprises job-specific behaviors which include accomplishing the role responsibilities and activities listed in in job description.

Reliability study
Our AI video assessment tool is highly reliable and accurate to our client’s internal rating. We analyzed the efficiency of our product by comparing our AI scores to HR (Client) internal rating:
Cronbach’s Alpha > 0.7 (out of 1) for reliability
0.3 - 0.6 (out of 1) positive Pearson correlation which is highly correlated to HR candidate ratings at p<0.05 significant level at competency-level.
F1 classification accuracy reaches up to 98% at competency-level.
