súlykvantálással

Súlykvantálás is a Hungarian term that translates to "weight quantization" or "weight discretization." In the context of artificial intelligence and machine learning, it refers to the process of reducing the precision of the numerical weights used in neural networks. Typically, neural network weights are stored and computed using high-precision floating-point numbers, such as 32-bit floats. Súlykvantálás involves converting these high-precision weights to lower-precision representations, commonly 8-bit integers or even binary values.

The primary motivation behind súlykvantálás is to enable more efficient deployment of neural networks, especially on resource-constrained hardware like mobile devices, embedded systems, and specialized AI accelerators. Lower-precision weights require less memory storage, reduce the bandwidth needed for data transfer, and allow for faster computations using simpler arithmetic operations. This can lead to significant improvements in inference speed and a reduction in power consumption.

However, reducing the precision of weights can also lead to a loss of accuracy in the neural network's predictions. The challenge in súlykvantálás lies in finding a balance between efficiency gains and maintaining acceptable model performance. Various techniques exist to mitigate accuracy degradation, such as quantization-aware training, where the quantization process is simulated during the training phase to help the network adapt to the reduced precision. Other methods involve careful selection of quantization schemes and strategies for mapping floating-point values to discrete levels.
