A study on the effect of target object size in object detection
Recent years have seen an impressive increase in the efficiency and accuracy of object detection models through the use of Region-based Convolutional Neural Networks (RCNN). Studies have been carried out to improve object detection models. However, the detection of small objects still poses numerous …

Assessing classification confidence using a weighted exponential based technique with the Learn++ incremental learning algorithm
<p>Pattern recognition problems span a broad range of applications, where each application has its own tolerance on classification error. The varying levels of risk associated with many pattern recognition applications indicate the need for a versatile algorithm with the ability to measure its own …
