One-Minute Videos from Text Storyboards using Test-Time Training Transformers

2025-04-08

Current Transformer models struggle with generating one-minute videos due to the inefficiency of self-attention layers for long contexts. This paper explores Test-Time Training (TTT) layers, whose hidden states are themselves neural networks, offering greater expressiveness. Adding TTT layers to a pre-trained Transformer allows for the generation of one-minute videos from text storyboards. Experiments using a Tom and Jerry cartoon dataset show that TTT layers significantly improve video coherence and storytelling compared to baselines like Mamba 2 and Gated DeltaNet, achieving a 34 Elo point advantage in human evaluation. While artifacts remain, likely due to limitations of the 5B parameter model, this work demonstrates a promising approach scalable to longer videos and more complex narratives.

Real-time Neuroplasticity: Giving Pre-trained LLMs Real-time Learning

2025-04-08

This experimental technique, called "Neural Graffiti," uses a plug-in called the "Spray Layer" to inject memory traces directly into the final inference stage of pre-trained large language models (LLMs) without fine-tuning or retraining. Mimicking the neuroplasticity of the brain, it subtly alters the model's "thinking" by modifying vector embeddings, influencing its generative token predictions. Through interaction, the model gradually learns and evolves. While not forcing specific word outputs, it biases the model towards associated concepts with repeated interaction. The aim is to give AI models more proactive behavior, focused personality, and enhanced curiosity, ultimately helping them achieve a form of self-awareness at the neuron level.

SeedLM: A Novel LLM Weight Compression Method Using Pseudo-Random Number Generators

2025-04-06

Large Language Models (LLMs) are hindered by high runtime costs, limiting widespread deployment. Meta researchers introduce SeedLM, a novel post-training compression method using seeds from a pseudo-random number generator to encode and compress model weights. During inference, SeedLM uses a Linear Feedback Shift Register (LFSR) to efficiently generate a random matrix, linearly combined with compressed coefficients to reconstruct weight blocks. This reduces memory access and leverages idle compute cycles, speeding up memory-bound tasks by trading compute for fewer memory accesses. Unlike state-of-the-art methods requiring calibration data, SeedLM is data-free and generalizes well across diverse tasks. Experiments on the challenging Llama 3 70B show zero-shot accuracy at 4- and 3-bit compression matching or exceeding state-of-the-art methods, while maintaining performance comparable to FP16 baselines. FPGA tests demonstrate that 4-bit SeedLM approaches a 4x speed-up over an FP16 Llama 2/3 baseline as model size increases.
