Have I Seen Enough? Frozen Video-Language Models Encode Evidence Readiness
Dan Ben-Ami, Kobi Cohen, Chaim Baskin
Streaming video-language models must decide not only what to answer, but whether the evidence needed for the current question has arrived. Existing systems learn that decision as a…
HiMu: Hierarchical Multimodal Frame Selection for Long Video Question Answering
Dan Ben-Ami, Gabriele Serussi, Kobi Cohen +1
Long-form video question answering requires reasoning over extended temporal contexts, making frame selection a critical bottleneck for multi-modal large language models (MLLMs) bo…
HERBench: A Benchmark for Multi-Evidence Integration in Video Question Answering
Dan Ben-Ami, Gabriele Serussi, Kobi Cohen +1
Video Large Language Models (Video-LLMs) are improving rapidly, yet current Video Question Answering (VideoQA) benchmarks often admit single-cue shortcuts, under-testing reasoning…
A Stable Polygamy Approach to Spectrum Access with Channel Reuse
Dan Ben Ami, Kobi Cohen
We introduce a new and broader formulation of the stable marriage problem (SMP), called the stable polygamy problem (SPP), where multiple individuals from a larger group of $|L…
A Genetic Algorithm-Based Approach to Power Allocation in Rate-Splitting Multiple Access Systems
Temitope O. Fajemilehin, Kobi Cohen
We consider the problem of power allocation in Rate-Splitting Multiple Access (RSMA) systems, where messages are split into common and private messages. The common and private stre…
