In this episode, we discuss NEPTUNE: THE LONG ORBIT TO BENCHMARKING LONG VIDEO UNDERSTANDING by The authors of the paper "NEPTUNE: THE LONG ORBIT TO BENCHMARKING LONG VIDEO UNDERSTANDING" are: - Arsha Nagrani - Mingda Zhang - Ramin Mehran - Rachel Hornung - Nitesh Bharadwaj Gundavarapu - Nilpa Jha - Austin Myers - Xingyi Zhou - Boqing Gong - Cordelia Schmid - Mikhail Sirotenko - Yukun Zhu - Tobias Weyand. The paper introduces "Neptune," a semi-automatic system designed to generate complex question-answer-decoy sets from long video content to enhance comprehension tasks typically limited to short clips. Leveraging large models like Vision-Language Models and Large Language Models, Neptune creates detailed, time-aligned captions and intricate QA sets for videos up to 15 minutes long, aiming to improve annotation efficiency. The dataset emphasizes multimodal reasoning and introduces the GEM metric for evaluating responses, revealing current long video models' weaknesses in understanding temporal and state changes.

In this episode, we discuss SHIC: Shape-Image Correspondences with no Keypoint Supervision by Aleksandar Shtedritski, Christian Rupprecht, Andrea Vedaldi. The paper introduces SHIC, a novel method for learning canonical surface mappings without manual supervision by using foundation models such as DINO and Stable Diffusion. SHIC simplifies the task to image-to-image correspondence prediction, outperforming some supervised techniques. The method uses non-photorealistic template renders to effectively simulate manual annotation, allowing reliable canonical map creation for diverse objects.

In this episode, we discuss E.T. Bench: Towards Open-Ended Event-Level Video-Language Understanding by Ye Liu, Zongyang Ma, Zhongang Qi, Yang Wu, Ying Shan, Chang Wen Chen. The paper introduces E.T. Bench, a comprehensive benchmark for fine-grained event-level video understanding, evaluating Video-LLMs across 12 tasks and 7K videos. It highlights the challenges these models face in accurately understanding and grounding events within videos. To improve performance, E.T. Chat and an instruction-tuning dataset, E.T. Instruct 164K, are proposed, enhancing models' abilities and underlining the necessity for advanced datasets and models in temporal and multi-event video-language tasks.

In this episode, we discuss LLaVA-3D: A Simple yet Effective Pathway to Empowering LMMs with 3D-awareness by Chenming Zhu, Tai Wang, Wenwei Zhang, Jiangmiao Pang, Xihui Liu. Recent advancements in Large Multimodal Models (LMMs) have significantly improved 2D visual understanding but 3D scene understanding has lagged due to dataset and encoder limitations. The paper introduces LLaVA-3D, a framework that adapts 2D LMMs for 3D understanding by using a 3D Patch representation to link 2D features with 3D positions. This integration allows effective 3D scene understanding without losing 2D capabilities, facilitated by joint 2D and 3D vision-language instruction tuning.

In this episode, we discuss DepthCrafter: Generating Consistent Long Depth Sequences for Open-world Videos by Wenbo Hu, Xiangjun Gao, Xiaoyu Li, Sijie Zhao, Xiaodong Cun, Yong Zhang, Long Quan, Ying Shan. DepthCrafter is a novel method for estimating temporally consistent depth in open-world videos without needing additional data like camera poses or optical flow. It generalizes to diverse video content by utilizing a three-stage training strategy rooted in a pre-trained image-to-video diffusion model, enabling it to handle up to 110-frame sequences. Evaluations show DepthCrafter's state-of-the-art performance, bolstering applications like depth-based visual effects and conditional video generation.

In this episode, we discuss Programming Every Example: Lifting Pre-training Data Quality like Experts at Scale by Fan Zhou, Zengzhi Wang, Qian Liu, Junlong Li, Pengfei Liu. The paper introduces Programming Every Example (PROX), a framework that enables small language models to refine pre-training corpora by executing fine-grained operations on individual examples, outperforming traditional human-crafted rules. Experimental results show that models trained on PROX-curated data achieve over 2% higher performance across various benchmarks compared to other data selection methods. PROX also significantly enhances domain-specific continual pre-training and reduces training FLOPs, with the authors open-sourcing their data and models for further research.

In this episode, we discuss Phantom of Latent for Large Language and Vision Models by Byung-Kwan Lee, Sangyun Chung, Chae Won Kim, Beomchan Park, Yong Man Ro. The paper introduces Phantom, an efficient LLVM family designed to perform comparably to larger models but with significantly smaller sizes, ranging from 0.5B to 7B parameters. By temporarily increasing the latent hidden dimension during multi-head self-attention, Phantom enhances learning capabilities without a substantial increase in model size. Phantom Optimization (PO) combines autoregressive supervised fine-tuning and a direct preference optimization-like concept, resulting in state-of-the-art performance against larger LLVMs.

In this episode, we discuss Fine-Tuning Image-Conditional Diffusion Models is Easier than You Think by Gonzalo Martin Garcia, Karim Abou Zeid, Christian Schmidt, Daan de Geus, Alexander Hermans, Bastian Leibe. The study identifies and corrects a flaw in the inference pipeline of large diffusion models used for monocular depth estimation, achieving over 200× speed improvement without compromising accuracy. By end-to-end fine-tuning with task-specific losses, the researchers attain a deterministic model that surpasses all other diffusion-based depth and normal estimation models on zero-shot benchmarks. Moreover, applying this fine-tuning protocol to Stable Diffusion models yields performance comparable to state-of-the-art, challenging prior conclusions in the field.

In this episode, we discuss On the Diagram of Thought by Yifan Zhang, Yang Yuan, Andrew Chi-Chih Yao. Diagram of Thought (DoT) is a framework for modeling iterative reasoning in large language models (LLMs) using a directed acyclic graph (DAG) to organize propositions, critiques, refinements, and verifications. This method allows the model to navigate complex reasoning pathways, improving its logic through natural language feedback via role-specific tokens. DoT also incorporates Topos Theory to ensure logical consistency, enhancing training and inference within a single model without the need for multiple models or external controls.

In this episode, we discuss Source2Synth: Synthetic Data Generation and Curation Grounded in Real Data Sources by Alisia Lupidi, Carlos Gemmell, Nicola Cancedda, Jane Dwivedi-Yu, Jason Weston, Jakob Foerster, Roberta Raileanu, Maria Lomeli. The paper presents Source2Synth, a method designed to enhance Large Language Models (LLMs) by generating synthetic data with intermediate reasoning steps, grounded in real-world sources, to improve performance without costly human annotations. Source2Synth also filters out low-quality data points to ensure high-quality datasets. The method demonstrates significant improvements in performance for multi-hop question answering and tool usage in tabular question answering, with respective boosts of 22.57% on HotPotQA and 25.51% on WikiSQL.
