Regularization is a vital tool in machine learning and deep learning for mitigating overfitting, a scenario where the model learns the training data too precisely. Overfitting can lead to a model failing to predict future data accurately. Regularization techniques are designed to help the model generalize better to new data.
Two popular regularization techniques are L1…
Hospitals are typically burdened with a significant amount of paperwork and have historically relied on manual data entry. This method not only consumes time, but also increases the potential for errors that could critically impact patient care. In response to these challenges, Optical Character Recognition (OCR) software has emerged as a groundbreaking solution that is…
This paper introduces the VisionLLaMA, a large language model based on transformer architectures, designed to bridge the gap between language and vision modalities. It follows the design of the LLaMA family of models and the Vision Transformer (ViT) pipeline, by segmenting an image into non-overlapping patches and processing them through VisionLLaMA blocks. The blocks include…
Traditionally, machine learning models have been trained and tested on data from the same distribution. However, researchers have found that models perform more effectively when dealing with data from multiple distributions. This flexibility is often achieved through “rich representations,” surpassing the capabilities of models trained on traditional sparsity-inducing regularization or common stochastic gradient methods.
However, optimizing…
This blog explains how to improve Large Language Models (LLMs) with Retrieval-Augmented Generation (RAG) using an innovative Python library called LlamaIndex. The author first shows the necessary Python libraries and their related installation commands.
The next step is to set up the knowledge base, which involves defining various parameters for the embedding model, chunk size,…
Marketing history is fraught with examples of content campaigns that have failed, despite businesses investing considerable resources. The problem often lies in our general fatigue from content saturation and the lack of personalized, targeted content produced by tools like artificial intelligence (AI). While AI-generated content may seem adequate, it often lacks individuality and a focus…
Medicaid, the US government-run health insurance program for low-income individuals and families, is a critical resource for millions of Americans. Despite the crucial role it plays in delivering healthcare, Medicaid has faced political and financial instability. Numerous measures have been taken to strengthen the program, notably the expansion of Medicaid under the Affordable Care Act…
On March 8, 2024, Microsoft engineer Shane Jones sounded the alarm regarding potential issues with Copilot Designer, an AI image generator developed by Microsoft. Jones, who has six years of experience with the company, revealed his findings publicly after conducting personal investigations into the tool's capabilities.
Copilot Designer is a command-line utility powered by OpenAI's…
This week in AI news, researchers have shown how AI can be used to recreate scents and generate precise 3D models of dogs. The AI model used for the latter was trained with a dataset built from the video game Grand Theft Auto V. In addition to these novel applications, there has been notable use…
Academics from the University of Washington, Western Washington University, and the University of Chicago have devised a method of manipulating language-learning models (LLMs), such as GPT-3.5, GPT-4, Gemini, Claude, and Llama2, utilizing a tactic known as ArtPrompt. ArtPrompt involves the use of ASCII art, a form of design made from letters, numbers, symbols, and punctuation…
Large Vision-Language Models (LVLMs), which combine powerful language and vision encoders, have shown excellent proficiency in tasks involving real-world images. However, they have generally struggled with abstract ideas, primarily due to their lack of exposure to domain-specific data during training. This is particularly true for areas requiring abstract reasoning, such as physics and mathematics.
To address…
The development of large language models (LLMs) in artificial intelligence has greatly influenced how machines comprehend and create text, demonstrating high accuracy in mimicking human conversation. These models have found utility in multiple applications, including content creation, automated customer support, and language translation. Yet, the practical deployment of LLMs is often incapacitated due to their…
