Pharmacovigilance

974
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...

Detection of Gross Error: The Q Test

6.4K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

Area of Science:

  • Food Science
  • Artificial Intelligence
  • Risk Management

Background:

  • Food safety is a critical global concern requiring robust early warning and risk control systems.
  • Effective management of food safety relies on accurate detection and classification of product quality.

Purpose of the Study:

  • To develop an innovative anomaly score-based risk early warning system (ASRWS) for food products.
  • To classify products as qualified or unqualified using an unsupervised auto-encoder (AE) model based on reconstruction errors.

Main Methods:

  • An unsupervised auto-encoder (AE) model was employed for anomaly detection in food product testing data.
  • The system utilizes reconstruction errors to classify products and early warning thresholds for risk analysis.
  • A hybrid approach combining AI predictions with expert risk revision was implemented.

Main Results:

  • The AE model demonstrated high prediction accuracy (0.9954) and fault detection rate (0.9024) on dairy product data.
  • The system achieved rapid analysis within 0.54 seconds.
  • Expert revision enhanced the reliability of AI-driven food safety predictions.

Conclusions:

  • The proposed ASRWS offers a fast, cost-effective solution for food safety early warning using detection data.
  • AI integration improves the efficiency of food safety expert panels.
  • The study supports market supervision departments in proactively controlling food safety risks.
