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.

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
A ferramenta de avaliação em vídeo com IA sem vieses da Neufast identifica a motivação do candidato para iniciar comportamentos relacionados ao trabalho, visando à adequação pessoa-vaga e à retenção de talentos.

Assessment of
Work Performance
O modelo de competências da Neufast é construído a partir de estudos acumulados sobre desempenho no trabalho. Os candidatos serão avaliados por seu desempenho em tarefas, contextual e adaptativo.

Reliability study
Nossa ferramenta de avaliação em vídeo com IA é altamente confiável e precisa em relação à avaliação interna do nosso cliente. Analisamos a eficiência do nosso produto comparando nossas pontuações de IA com a avaliação interna do RH (cliente):
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.
