WebThis is why recent deep learning approaches mostly include some “attention” mechanism (sometimes even more than one) to help focusing on relevant image features. In this post, we demonstrate a formulation of image captioning as an encoder-decoder problem, enhanced by spatial attention over image grid cells. WebBottom-Up and Top-Down Attention for Image Captioning and Visual Question Answering. ... Top-down visual attention mechanisms have been used extensively in image captioning and visual question answering (VQA) to enable deeper image understanding through fine-grained analysis and even multiple steps of reasoning. 63.

WebTechnically, conditioned on the bottom-up signals (all detected objects), an LSTM-based object inference module is first learned to produce the object sequence of interest, which acts as the top-down prior to mimic the subjective experience of humans. WebIt is believed that visual attention is driven by two independent factors: (1) a bottom-up component, which is a task-independent component purely based on the low-level information, and (2) a top-down component, which is based on high-level information and guides attention through the volitionally controlled mecha-nisms. creative vado hd battery
