Large Language Models (LLMs) like ChatGPT have received significant interest due to their ability to perform varied AI tasks from language processing to tool use. These capabilities have pushed research toward creating more sophisticated AI models, opening possibilities for Artificial General Intelligence (AGI).
LLMs are built on the Transformer neural network architecture, using autoregressive learning to…
Research from MIT and other institutions has developed a method, called StreamingLLM, that enables AI chatbots to maintain continuous dialogue without crashing or slowing down. The technique tweaks the key-value cache or conversation memory at the core of large language models. Failure often occurs when this cache needs to store more information than it can…
Researchers from several universities in China and UK have jointly developed a new method for Graph Neural Networks (GNNs), known as Edge-Node Attention-based Differentiable Pooling (ENADPool). This method uses hard clustering and incorporates attention mechanisms to compress node features and edge strengths in GNNs. They also introduced the Multi-distance GNN (MD-GNN) model to mitigate over-smoothing…
State-space models (SSMs) are an essential part of deep learning, used for sequence modeling. They observe a system where the output depends both on current and earlier inputs. This mechanism is utilized extensively in signal processing, control systems, and natural language processing. There lays a challenge with SSMs, it lies in their execution inefficiency, especially…
The paper discussed in this largely explored the effectiveness of machine-learning-based models in wireless link path loss predictions, in lieu of traditional models like Longley-Rice and free space path loss (FSPL). Traditional models suffer in accuracy in non-line-of-sight scenarios due to their inability to account for signal attenuation, or interference caused by electromagnetic interplay with…
Researchers from Columbia University and Databricks Mosaic AI have conducted a comparative study of full finetuning and Low-Rank Adaptation (LoRA), a parameter-efficient finetuning method, in large language models (LLMs). The efficient finetuning of LLMs, which can contain billions of parameters, is an ongoing challenge due to the substantial GPU memory required. This makes the process…
Recent research suggests that incorporating demonstrating examples, or in-context learning (ICL), significantly enhances large language models' (LLM's) and large multimodal models' (LMM's) performance. Studies have shown improvements in LLM performance with increased in-context examples, particularly in out-of-domain tasks. These findings are driven by newer models such as GPT-4o and Gemini 1.5 Pro, which include longer…
A team of researchers from MIT and other institutions has discovered a key issue with large-scale machine learning models causing chatbot performance to degrade. When engaged in extensive dialogues, the huge language models behind bots like ChatGPT sometimes begin to fail. However, the team devised a solution enabling nonstop conversation without deterioration or lag. The…
Machine learning (ML) has become a fundamental part of several industries worldwide due to its wide range of applications. However, understanding and interpreting complex ML models continues to be a challenge. These models, often comprising multiple layers and intricate connections, require precise graph visualization tools to understand how data travels across the model and how…
Machine Learning (ML) models are increasingly becoming an integral part of various sectors globally, with their extensive applications and growing reliance on their capabilities. As these models grow in complexity, understanding and interpreting them becomes more challenging. Visualizing how data flows through the model and how the different parts interact is crucial to debug and…
When engaging in lengthy dialogues, advanced AI-powered chatbots often become inept, resulting in a significant performance downturn. A team of researchers from MIT alongside others have deduced a reason for this issue and devised a straightforward solution to prevent the bot from crashing or slowing down. The method, StreamingLLM, effectively ensures a continuous discussion irrespective…
