Artificial Intelligence Trends in Healthcare in 2023
Andrew Brosnan, principal analyst at research firm Omdia, predicts that although the healthcare industry is initially slow to embrace artificial intelligence, healthcare and pharmaceutical companies will increase it rapidly in the next few years. Adoption of artificial intelligence, medical image analysis and drug discovery will be the most popular use cases.
Healthcare spending on AI software is expected to grow 40% in 2023, from $4.4 billion in 2022 to nearly $6.2 billion in the new year, according to Omdia forecasts.
"Healthcare will grow faster than most other industries, and according to our forecasts, we expect healthcare to rank second behind consumers in AI spending in 2027," Omdia Artificial Intelligence and Brosnan of the Intelligent Automation practice said.
Healthcare AI adoption will catch up with other industries
Brosnan said healthcare companies have historically been conservative in adopting new technologies because of risks to patient care and privacy, security and regulatory issues. Very high.
Healthcare lags behind other industries in artificial intelligence adoption. According to a 2022 OM Dia survey, while 25% of all industries have expanded AI deployment across multiple business units or functions, only 19% have done so in healthcare.
But this is changing rapidly. Artificial intelligence has proven effective in health care, which has fueled growth in use, he said. For example, artificial intelligence has been used during the epidemic to help health care providers with COVID-19 diagnosis, patient prognosis, and to help researchers understand changes in the spike protein.
“The use of AI during the pandemic and in proof-of-concept projects has increased confidence in the value AI can provide in healthcare,” said Brosnan.
In fact, 96% of healthcare organizations surveyed by Omdia in 2022 said they are confident or very confident that artificial intelligence will lead to positive outcomes, and 67% of respondents said that artificial intelligence will increase The ability to value has increased over the past year.
This will translate into significant investment in artificial intelligence. Spending on AI software will grow at a compound annual growth rate (CAGR) of 29% and reach $13.8 billion in spending in 2027, tied for the fastest-growing sector, according to Omdia.
Top Five Healthcare IT Use Cases
Medical image analysis is the most popular use case of artificial intelligence. With annual growth of 26%, it will retain the largest share of spending, reaching $2.6 billion in AI software spending in 2027.
Meanwhile, Omdia forecasts show that drug discovery will be the fastest-growing use case by 2027, with AI spending reaching $2 billion and a CAGR of 33%.
Other top use cases are virtual assistants such as online chatbots and intelligent document processing, both of which have a CAGR of 27%. AI spending for virtual assistants is expected to reach nearly $1.7 billion in 2027, while intelligent document processing (such as claims processing) is expected to reach $1 billion.
Medical advice – through tools such as clinical decision support – completes the top five use cases with a CAGR of 28% and $900 million in AI spending in 2027.
Innovating Drug Discovery
Brosnan said that artificial intelligence has the potential to speed up the drug discovery and development process and reduce its cost. In 2023, the pharmaceutical industry will continue to advance drug discovery through artificial intelligence.
The traditional drug discovery and development process currently takes approximately $1 billion and 10 years to bring a new drug to market. This involves synthesizing more than 5,000 molecules to advance a candidate into clinical trials, he said.
But with artificial intelligence, drugmakers can reduce the number of molecules they have to physically make by doing production "on the computer," meaning they can do it virtually, he said.
This reduced the number of molecules they had to physically synthesize to 250, which saved money and shortened time to market, Brosnan said. The pipeline of AI-first drug candidates is very strong, with 18 candidates entering clinical trials in 2022. In 2020, that number was zero.
"Early-stage drug discovery takes months or even years," he said.
Emerging technologies could better train healthcare AI models
Federated learning, or group learning, is an emerging technology that will allow healthcare providers to safely use it with patients, Brosnan said. data to better train AI models and will gain greater traction in 2023.
To reduce bias, it is important to train AI models against large data sets. But to do that, many healthcare organizations want to share data so they can build a more comprehensive dataset to train AI models.
Traditionally, they had to move data to a central repository. However, with federated or group learning, the data does not have to move. Instead, he said, the AI model goes to each individual health care facility and is trained on the data. In this way, healthcare providers can maintain the security and governance of their data.
“With federated or swarm learning, the data does not have to leave the source institution, but the AI model moves to the data,” Brosnan said. Federated learning uses a centralized orchestrator, while swarm learning is more distributed and does not use a centralized orchestrator.
This technology is currently undergoing a proof of concept. In 2021, major pharmaceutical company Sanofi invested $180 million in a healthcare-focused federated learning company.
"This is an emerging technology and we will see the rise of it in 2023 and 2024," he said.

Context-augmented AI coding assistant using Rag and Sem-Rag
Jun 10, 2024 am 11:08 AM
Improve developer productivity, efficiency, and accuracy by incorporating retrieval-enhanced generation and semantic memory into AI coding assistants. Translated from EnhancingAICodingAssistantswithContextUsingRAGandSEM-RAG, author JanakiramMSV. While basic AI programming assistants are naturally helpful, they often fail to provide the most relevant and correct code suggestions because they rely on a general understanding of the software language and the most common patterns of writing software. The code generated by these coding assistants is suitable for solving the problems they are responsible for solving, but often does not conform to the coding standards, conventions and styles of the individual teams. This often results in suggestions that need to be modified or refined in order for the code to be accepted into the application
Can fine-tuning really allow LLM to learn new things: introducing new knowledge may make the model produce more hallucinations
Jun 11, 2024 pm 03:57 PM
Large Language Models (LLMs) are trained on huge text databases, where they acquire large amounts of real-world knowledge. This knowledge is embedded into their parameters and can then be used when needed. The knowledge of these models is "reified" at the end of training. At the end of pre-training, the model actually stops learning. Align or fine-tune the model to learn how to leverage this knowledge and respond more naturally to user questions. But sometimes model knowledge is not enough, and although the model can access external content through RAG, it is considered beneficial to adapt the model to new domains through fine-tuning. This fine-tuning is performed using input from human annotators or other LLM creations, where the model encounters additional real-world knowledge and integrates it

Five schools of machine learning you don't know about
Jun 05, 2024 pm 08:51 PM
Machine learning is an important branch of artificial intelligence that gives computers the ability to learn from data and improve their capabilities without being explicitly programmed. Machine learning has a wide range of applications in various fields, from image recognition and natural language processing to recommendation systems and fraud detection, and it is changing the way we live. There are many different methods and theories in the field of machine learning, among which the five most influential methods are called the "Five Schools of Machine Learning". The five major schools are the symbolic school, the connectionist school, the evolutionary school, the Bayesian school and the analogy school. 1. Symbolism, also known as symbolism, emphasizes the use of symbols for logical reasoning and expression of knowledge. This school of thought believes that learning is a process of reverse deduction, through existing
To provide a new scientific and complex question answering benchmark and evaluation system for large models, UNSW, Argonne, University of Chicago and other institutions jointly launched the SciQAG framework
Jul 25, 2024 am 06:42 AM
Editor |ScienceAI Question Answering (QA) data set plays a vital role in promoting natural language processing (NLP) research. High-quality QA data sets can not only be used to fine-tune models, but also effectively evaluate the capabilities of large language models (LLM), especially the ability to understand and reason about scientific knowledge. Although there are currently many scientific QA data sets covering medicine, chemistry, biology and other fields, these data sets still have some shortcomings. First, the data form is relatively simple, most of which are multiple-choice questions. They are easy to evaluate, but limit the model's answer selection range and cannot fully test the model's ability to answer scientific questions. In contrast, open-ended Q&A
SOTA performance, Xiamen multi-modal protein-ligand affinity prediction AI method, combines molecular surface information for the first time
Jul 17, 2024 pm 06:37 PM
Editor | KX In the field of drug research and development, accurately and effectively predicting the binding affinity of proteins and ligands is crucial for drug screening and optimization. However, current studies do not take into account the important role of molecular surface information in protein-ligand interactions. Based on this, researchers from Xiamen University proposed a novel multi-modal feature extraction (MFE) framework, which for the first time combines information on protein surface, 3D structure and sequence, and uses a cross-attention mechanism to compare different modalities. feature alignment. Experimental results demonstrate that this method achieves state-of-the-art performance in predicting protein-ligand binding affinities. Furthermore, ablation studies demonstrate the effectiveness and necessity of protein surface information and multimodal feature alignment within this framework. Related research begins with "S
