Behavioral signals

Zoe Weil discusses how recommendation and ranking systems can use in-session behavioral signals to model intent and optimize purchasing outcomes. The episode examines event-to-feature models, low-latency ranking infrastructure, evaluation against business outcomes, and the distinction between click relevance and useful recommendations. It also considers privacy tradeoffs in personalization and the relationship between advertising and organic revenue.

…local field potentials (LFPs), and behavioral signals capture various aspects of brain processes. By leveraging the complementary strengths of different modalities, multimodal fusion can not only construct a rich and unified representation of brain processes, but also address the limitations of single-modality analyses---such as incomplete or noisy data. An exciting recent direction has been to build models of simultaneously recorded neural and

…information and lower-dimensional behavioral variables. Here we asked how behavioral signals are organized across the cortical volume, and whether they follow the organization of visual activity.[Methods] We used Light Beads Microscopy (Demas et al, 2021) to functionally image Ca2+ transients at cellular resolution from large volumes of cortex (3 x 3 x 0.5 mm^3) in awake, headfixed transgenic mice expressing GCaMP6s. To segment individual cells, we developed a novel volumetric cell extraction pipeline by accelerating and ext
