Summary
This study introduces a novel semi-supervised learning and on-shelf availability (SOSA) method for monitoring grocery store stock. The SOSA method, utilizing YOLOv4, significantly improves accuracy in detecting on-shelf availability.
Area of Science:
- Computer Vision
- Machine Learning
- Retail Analytics
Background:
- High on-shelf availability (OSA) is crucial for grocery store profitability.
- Existing computer vision datasets lack product annotations, necessitating manual labeling for OSA monitoring.
- Current methods require substantial manual effort for product labeling in images.
Purpose of the Study:
- To introduce a novel method combining semi-supervised learning and on-shelf availability (SOSA) to address the product annotation challenge.
- To apply the You Only Look Once (YOLOv4) deep learning architecture for OSA monitoring for the first time.
- To demonstrate explainable artificial intelligence (XAI) for OSA monitoring through a new software application, SOSA XAI.
Main Methods:
- Proposed a new semi-supervised learning and on-shelf availability (SOSA) method.
- Utilized the YOLOv4 deep learning architecture for OSA monitoring.
- Developed the SOSA XAI software application integrating explainable artificial intelligence.
Main Results:
- The SOSA method demonstrated effectiveness across image datasets with varying labeled sample ratios (20% to 80%).
- Experimental results confirmed the proposed SOSA approach surpasses existing methods like RetinaNet and YOLOv3 in accuracy.
- The SOSA XAI application provides explainability for OSA monitoring.
Conclusions:
- The proposed SOSA method offers a more accurate and efficient solution for monitoring on-shelf availability.
- The integration of YOLOv4 and XAI in SOSA XAI represents a significant advancement in retail analytics.
- This approach reduces the need for extensive manual labeling, saving time and resources in grocery inventory management.

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Aggregates Classification

Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
