​​CoTracker: It is Better to Track Together

The CoTracker paper proposes a groundbreaking approach that takes video motion prediction to the next level. Traditional methods have often been limited, either tracking the motion of all points in a frame collectively using optical flow, or tracking individual points through a video. These approaches tend to overlook the crucial interrelationships between multiple points, especially when they're part of the same physical object. CoTracker flips the script by employing a transformer-based architecture to jointly track multiple points throughout a video, effectively modeling the correlations between different points in time.

What really sets CoTracker apart is its versatility and adaptability. It's engineered to handle extremely long videos through a unique sliding-window mechanism, and iteratively updates estimates for multiple trajectories. The system even allows for the addition of new tracking points on-the-fly, offering unmatched flexibility. CoTracker outshines state-of-the-art methods in nearly all benchmark tests.

​​LISA: Reasoning Segmentation via Large Language Model

The field of image segmentation has taken a leap forward with the introduction of LISA (Large Language Instructed Segmentation Assistant). This cutting-edge model excels at "reasoning segmentation," a novel task that generates segmentation masks from complex and implicit text queries. Building upon the capabilities of multi-modal Large Language Models, LISA expands its vocabulary with a <SEG> token and introduces an innovative "embedding-as-mask" paradigm to achieve this feat. Notably, the model is adept at intricate reasoning, utilizes world knowledge, offers explanatory answers, and can handle multi-turn conversations.

What's astonishing about LISA is its robust zero-shot learning abilities. Even when trained on datasets that lack reasoning-based tasks, LISA performs impressively well. Moreover, when fine-tuned with just 239 specific reasoning segmentation image-instruction pairs, the model's performance is further enhanced.

​​TabR: Unlocking the Power of Retrieval-Augmented Tabular Deep Learning

The deep learning arena is abuzz with the rise of models designed for tabular data problems, challenging the traditional dominance of gradient-boosted decision trees (GBDT) algorithms. Among these, retrieval-augmented tabular DL models, which gather relevant training data like nearest neighbors for better prediction, are gaining traction. However, these novel models have only shown marginal benefits over properly tuned retrieval-free baselines, sparking a debate on the effectiveness of the retrieval-based approach.

In response to this uncertainty, this groundbreaking work presents TabR, an innovative retrieval-based tabular DL model. This breakthrough was achieved by augmenting a simple feed-forward architecture with an attention-like retrieval component. Several overlooked aspects of the attention mechanism were highlighted, leading to major performance improvements. On a set of public benchmarks, TabR stole the show, demonstrating unparalleled average performance, becoming the new state-of-the-art on numerous datasets, and even outperforming GBDT models on a recent benchmark designed to favor them.

​​Retentive Network: A Successor to Transformer for Large Language Models

The Retentive Network (RetNet) has been proposed as a game-changing foundation architecture for large language models. RetNet uniquely combines training parallelism, low-cost inference, and impressive performance into one sleek package. It ingeniously draws a theoretical connection between recurrence and attention, opening new avenues in AI exploration. The introduction of the retention mechanism for sequence modeling further enhances this innovation, featuring not one, not two, but three computation paradigms - parallel, recurrent, and chunkwise recurrent!

Specifically, the parallel representation provides the horsepower for training parallelism, while the recurrent representation supercharges low-cost O(1) inference, enhancing decoding throughput, latency, and GPU memory without compromising performance. For long-sequence modeling, the chunkwise recurrent representation is the ace up RetNet's sleeve, enabling efficient handling with linear complexity. Each chunk is encoded in parallel while also recurrently summarizing the chunks, which is nothing short of revolutionary. Based on experimental results in language modeling, RetNet delivers strong scaling results, parallel training, low-cost deployment, and efficient inference. All these groundbreaking features position RetNet as a formidable successor to the Transformer for large language models.

​​Giraffe: Adventures in Expanding Context Lengths in LLMs

Modern Large Language Models (LLMs) have revolutionized our ability to process and understand vast amounts of textual data. Yet, these models, like LLaMA and LLaMA2, often come with a caveat: they're constrained by fixed context lengths, which means they're limited in handling longer sequences of input data at evaluation. This paper tackles that constraint by investigating a variety of methods for "context length extrapolation," which essentially enables these models to understand and work with longer text sequences. Among the techniques explored, the paper introduces an innovative "truncated basis" strategy for altering positional encodings within the attention mechanism, promising a more scalable future for LLMs.

The researchers put their theories to the test with three brand-new evaluation tasks—FreeFormQA, AlteredNumericQA, and LongChat-Lines—providing a more nuanced measure of model performance than the traditionally used metric of perplexity. Their findings? Linear scaling came out on top as the most effective way to extend the context length, but the truncated basis method showed potential for future exploration. To propel the research community even further, the paper releases three game-changing long-context models, named Giraffe, with context lengths ranging from 4k to an astonishing 32k.
