Creative writing is a domain that thrives on diversity and imagination. Unlike fact-based or task-specific writing, where a single correct output may exist, creative writing involves numerous valid responses to a prompt. Stories, poems, and narratives can branch in countless directions, each with stylistic flavor and meaning. This inherent open-mindedness makes creative writing a prime challenge for AI systems, which need to maintain narrative coherence while producing novel and distinct outputs. The core issue lies in how large language models are refined after their initial training. Post-training methods often emphasize quality improvements by aligning responses with user preferences or maximizing reward scores. However, these adjustments inadvertently cause the models to produce responses that are too similar across prompts. In creative settings, this leads to a noticeable drop in output diversity. A lack of variation limits the expressive power of the model, resulting in uniform ...

LLMs have shown impressive capabilities in reasoning tasks like Chain-of-Thought (CoT), enhancing accuracy and interpretability in complex problem-solving. While researchers are extending these capabilities to multi-modal domains, videos present unique challenges due to their temporal dimension. Unlike static images, videos require understanding dynamic interactions over time. Current visual CoT methods excel with static inputs but struggle with video content because they cannot explicitly localize or revisit specific moments in sequences. Humans overcome these challenges by breaking down complex problems, identifying and revisiting key moments, and synthesizing observations into coherent answers. This approach highlights the need for AI systems to manage multiple reasoning abilities. Recent video understanding advances have improved tasks like captioning and question answering, but models often lack visual-grounded correspondence and interpretability, especially for long-form videos....

Approximate Nearest Neighbor Search (ANNS) is a fundamental vector search technique that efficiently identifies similar items in high-dimensional vector spaces. Traditionally, ANNS has served as the backbone for retrieval engines and recommendation systems, however, it struggles to keep pace with modern Transformer architectures that employ higher-dimensional embeddings and larger datasets. Unlike deep learning systems that can be horizontally scaled due to their stateless nature, ANNS remains centralized, creating a severe single-machine throughput bottleneck. Empirical testing with 100-million scale datasets reveals that even state-of-the-art CPU implementations of the Hierarchical Navigable Small World (HNSW) algorithm can’t maintain adequate performance as vector dimensions increase. Previous research on large-scale ANNS has explored two optimization paths: index structure improvements and hardware acceleration. The Inverted MultiIndex (IMI) enhanced space partitioning through mu...

Time series analysis faces significant hurdles in data availability, quality, and diversity, critical factors in developing effective foundation models. Real-world datasets often fall short due to regulatory limitations, inherent biases, poor quality, and limited paired textual annotations, making it difficult to create robust, generalizable Time Series Foundation Models (TSFMs) and Large Language Model -based Time Series Models (TSLLMs). This scarcity impacts tasks such as forecasting, classification, anomaly detection, reasoning, and captioning, limiting the full potential of current advancements in artificial intelligence. Salesforce AI Research has addressed these challenges by proposing a comprehensive approach to leveraging synthetic data for enhancing TSFMs and TSLLMs. Their recent study, “Empowering Time Series Analysis with Synthetic Data,” presents a novel strategy of using synthetic data to improve model training, evaluation, and fine-tuning, focusing on mitigating biases, ...

Large vision-language models (LVLMs) integrate large language models with image processing capabilities, enabling them to interpret images and generate coherent textual responses. While they excel at recognizing visual objects and responding to prompts, they often falter when presented with problems requiring multi-step reasoning. Vision-language tasks like understanding charts, solving visual math questions, or interpreting diagrams demand more than recognition; they need the ability to follow logical steps based on visual cues. Despite advancements in model architecture, current systems consistently struggle to produce accurate and interpretable answers in such complex scenarios. A major limitation in current vision-language models is their inability to perform complex reasoning that involves multiple steps of logical deduction, especially when interpreting images in conjunction with textual queries. These models cannot often internally verify or correct their reasoning, leading to ...

Autoregressive visual generation models have emerged as a groundbreaking approach to image synthesis, drawing inspiration from language model token prediction mechanisms. These innovative models utilize image tokenizers to transform visual content into discrete or continuous tokens. The approach facilitates flexible multimodal integrations and allows adaptation of architectural innovations from LLM research. However, the field has a critical challenge of determining the optimal token representation strategy. The choice between discrete and continuous token representations remains a fundamental dilemma, significantly impacting model complexity and generation quality. Existing methods include visual tokenization that explores two primary approaches: continuous and discrete token representations. Variational autoencoders establish continuous latent spaces that maintain high visual fidelity, becoming foundational in diffusion model development. Discrete methods like VQ-VAE and VQGAN enabl...

Large Vision-Language Models (LVLMs) have made significant strides in recent years, yet several key limitations persist. One major challenge is aligning these models effectively with human expectations, particularly for tasks involving detailed and precise visual information. Traditionally, LVLMs undergo a two-stage training paradigm: pretraining followed by supervised fine-tuning. However, supervised fine-tuning alone cannot fully overcome limitations, such as the scarcity and high cost associated with generating large-scale, human-annotated preference datasets. Moreover, conventional reinforcement learning methods require expensive reward models that may not fully capture the nuanced and subjective nature of human feedback. A team of researchers from China propose Vision-R1: a novel vision-guided R1-like reinforcement learning algorithm for LVLMs that rewards models with definitive vision feedback. Vision-R1 leverages curated instruction data, thereby eliminating the dependency on s...

Large Language Models (LLMs) are becoming integral to modern technology, driving agentic systems that interact dynamically with external environments. Despite their impressive capabilities, LLMs are highly vulnerable to prompt injection attacks. These attacks occur when adversaries inject malicious instructions through untrusted data sources, aiming to compromise the system by extracting sensitive data or executing harmful operations. Traditional security methods, such as model training and prompt engineering, have shown limited effectiveness, underscoring the urgent need for robust defenses. Google DeepMind Researchers propose CaMeL, a robust defense that creates a protective system layer around the LLM, securing it even when underlying models may be susceptible to attacks. Unlike traditional approaches that require retraining or model modifications, CaMeL introduces a new paradigm inspired by proven software security practices. It explicitly extracts control and data flows from user...
