Quantization For Retail

What is Quantization for Retail?

Quantization, in the context of retail, refers to the process of simplifying and optimizing data representation to improve computational efficiency without significantly compromising accuracy. It involves reducing the precision of numerical data, such as weights in machine learning models, to lower bit levels. In retail, quantization is applied to various domains, including inventory management, customer analytics, pricing strategies, and demand forecasting. By enabling faster computations and reducing resource consumption, quantization empowers retailers to make data-driven decisions in real-time.

Key Concepts and Terminology in Quantization for Retail

To fully grasp quantization for retail, it's essential to familiarize yourself with key concepts and terminology:

• Quantization Levels: The number of discrete values used to represent data. Lower levels result in higher compression but may reduce accuracy.
• Fixed-Point Representation: A method of representing numbers using a fixed number of bits, commonly used in quantization.
• Dynamic Range: The range between the smallest and largest values in a dataset. Quantization often involves scaling data to fit within a specific dynamic range.
• Post-Training Quantization: Applying quantization to a pre-trained model to optimize its performance for retail applications.
• Quantization-Aware Training: Training a machine learning model with quantization in mind, ensuring better accuracy after deployment.
• Compression Ratio: The ratio of the original data size to the quantized data size, indicating the level of optimization achieved.
