Deep convolutional neural networks (CNNs) are investigated in the context of computer-aided diagnosis (CADx) breast cancer. State-of-the-art CNNs trained and evaluated on two mammographic datasets, consisting ROIs depicting benign or malignant mass lesions. The performance evaluation each examined network is addressed training scenarios: first involves initializing with pre-trained weights, while for second initialized a random fashion. Extensive experimental results show superior achieved...

Autonomous vehicles integrate complex software stacks for realizing the necessary iterative perception, planning, and action operations. One of foundational layers such is perception one which comprised localization, detection, recognition algorithms understanding location driving environment around vehicle. More precisely, localization aims to identify vehicle on a global coordinate system considered most critical parts in stack since its accuracy robustness affects subsequent layer also...
