Citizen astronomers and AI discover 30,000 ring galaxies
Building on the synergy between citizen astronomer classifications and AI, astronomers have discovered approximately 400,000 spiral galaxies and 30,000 ring galaxies in data from the Subaru Telescope. This is the first example of research building on the classification data from the citizen science project "GALAXY CRUISE."
Galaxies display a wide variety of morphologies that reflect their histories. Data sets from powerful cutting-edge facilities like the Subaru Telescope contain so many galaxies that astronomers cannot classify them all by hand. In the GALAXY CRUISE citizen science project, professional astronomers asked more than 10,000 citizen astronomer volunteers to do the classifications. But even divided among thousands of volunteers, classification still takes time.
AI can conduct classifications quickly, but first it needs to be trained on a catalog of classification examples prepared by humans.
For this new study, a team led by Rhythm Shimakawa, associate professor at Waseda University, trained an AI on a set of 20,000 galaxies classified by humans as part of GALAXY CRUISE. The team then turned the AI loose on all 700,000 galaxies in the Subaru Telescope data set.
The AI classified 400,000 of them as spiral galaxies and 30,000 as ring galaxies. Even though ring galaxies account for less than 5% of all galaxies, this research yielded a sample large enough for meaningful statistical analysis.
Statistical analysis showed that on average, ring galaxies show intermediate characteristics between spiral and elliptical galaxies. This is consistent with the latest supercomputer simulations. The article, "GALAXY CRUISE: Spiral and ring classifications for bright galaxies at z = 0.01–0.3" was presented in Publications of the Astronomical Society of Japan on January 29, 2024.
Shimakawa comments about the role of GALAXY CRUISE in his research and future prospects, "Although AI classification takes less than one hour even for 700,000 galaxies, this work cannot be done without the data collected by GALAXY CRUISE over the past two years. We would like to thank all the citizen astronomers who participate in the project. I hope to see more collaborative outcomes in the future."

Data Annotation for Fine-tuning Large Language Models(LLMs)
Tumblr media
The beginning of ChatGPT and AI-generated text, about which everyone is now raving, occurred at the end of 2022. We always find new ways to push the limits of what we once thought was feasible as technology develops. One example of how we are using technology to make increasingly intelligent and sophisticated software is large language models. One of the most significant and often used tools in natural language processing nowadays is large language models (LLMs). LLMs allow machines to comprehend and produce text in a manner that is comparable to how people communicate. They are being used in a wide range of consumer and business applications, including chatbots, sentiment analysis, content development, and language translation.
What is a large language model (LLM)?
In simple terms, a language model is a system that understands and predicts human language. A large language model is an advanced artificial intelligence system that processes, understands, and generates human-like text based on massive amounts of data. These models are typically built using deep learning techniques, such as neural networks, and are trained on extensive datasets that include text from a broad range, such as books and websites, for natural language processing.
One of the critical aspects of a large language model is its ability to understand the context and generate coherent, relevant responses based on the input provided. The size of the model, in terms of the number of parameters and layers, allows it to capture intricate relationships and patterns within the text.
While analyzing large amounts of text data in order to fulfill this goal, language models acquire knowledge about the vocabulary, grammar, and semantic properties of a language. They capture the statistical patterns and dependencies present in a language. It makes AI-powered machines understand the user’s needs and personalize results according to those needs. Here’s how the large language model works:
LLMs need massive datasets to train AI models. These datasets are collected from different sources like blogs, research papers, and social media.
The collected data is cleaned and converted into computer language, making it easier for LLMs to train machines.
Training machines involves exposing them to the input data and fine-tuning its parameters using different deep-learning techniques.
LLMs sometimes use neural networks to train machines. A neural network comprises connected nodes that allow the model to understand complex relationships between words and the context of the text.
Need of Fine Tuning LLMs
Tumblr media
Fine-tuning a large language model involves adjusting and adapting a pre-trained model to perform specific tasks or cater to a particular domain more effectively. The process usually entails training the model further on a targeted dataset that is relevant to the desired task or subject matter. The original large language model is pre-trained on vast amounts of diverse text data, which helps it to learn general language understanding, grammar, and context. Fine-tuning leverages this general knowledge and refines the model to achieve better performance and understanding in a specific domain.
Fine-tuning a large language model (LLM) is a meticulous process that goes beyond simple parameter adjustments. It involves careful planning, a clear understanding of the task at hand, and an informed approach to model training. Let's delve into the process step by step:
Identify the Task and Gather the Relevant Dataset -The first step is to identify the specific task or application for which you want to fine-tune the LLM. This could be sentiment analysis, named entity recognition, or text classification, among others. Once the task is defined, gather a relevant dataset that aligns with the task's objectives and covers a wide range of examples.
Preprocess and Annotate the Dataset -Before fine-tuning the LLM, preprocess the dataset by cleaning and formatting the text. This step may involve removing irrelevant information, standardizing the data, and handling any missing values. Additionally, annotate the dataset by labeling the text with the appropriate annotations for the task, such as sentiment labels or entity tags.
Initialize the LLM -Next, initialize the pre-trained LLM with the base model and its weights. This pre-trained model has been trained on vast amounts of general language data and has learned rich linguistic patterns and representations. Initializing the LLM ensures that the model has a strong foundation for further fine-tuning.
Fine-Tune the LLM -Fine-tuning involves training the LLM on the annotated dataset specific to the task. During this step, the LLM's parameters are updated through iterations of forward and backward propagation, optimizing the model to better understand and generate predictions for the specific task. The fine-tuning process involves carefully balancing the learning rate, batch size, and other hyperparameters to achieve optimal performance.
Evaluate and Iterate -After fine-tuning, it's crucial to evaluate the performance of the model using validation or test datasets. Measure key metrics such as accuracy, precision, recall, or F1 score to assess how well the model performs on the task. If necessary, iterate the process by refining the dataset, adjusting hyperparameters, or fine-tuning for additional epochs to improve the model's performance.
Data Annotation for Fine-tuning LLMs
The wonders that GPT and other large language models have come to reality due to a massive amount of labor done for annotation. To understand how large language models work, it's helpful to first look at how they are trained. Training a large language model involves feeding it large amounts of data, such as books, articles, or web pages so that it can learn the patterns and connections between words. The more data it is trained on, the better it will be at generating new content.
Data annotation is critical to tailoring large-language models for specific applications. For example, you can fine-tune the GPT model with in-depth knowledge of your business or industry. This way, you can create a ChatGPT-like chatbot to engage your customers with updated product knowledge. Data annotation plays a critical role in addressing the limitations of large language models (LLMs) and fine-tuning them for specific applications. Here's why data annotation is essential:
Specialized Tasks: LLMs by themselves cannot perform specialized or business-specific tasks. Data annotation allows the customization of LLMs to understand and generate accurate predictions in domains or industries with specific requirements. By annotating data relevant to the target application, LLMs can be trained to provide specialized responses or perform specific tasks effectively.
Bias Mitigation: LLMs are susceptible to biases present in the data they are trained on, which can impact the accuracy and fairness of their responses. Through data annotation, biases can be identified and mitigated. Annotators can carefully curate the training data, ensuring a balanced representation and minimizing biases that may lead to unfair predictions or discriminatory behavior.
Quality Control: Data annotation enables quality control by ensuring that LLMs generate appropriate and accurate responses. By carefully reviewing and annotating the data, annotators can identify and rectify any inappropriate or misleading information. This helps improve the reliability and trustworthiness of the LLMs in practical applications.
Compliance and Regulation: Data annotation allows for the inclusion of compliance measures and regulations specific to an industry or domain. By annotating data with legal, ethical, or regulatory considerations, LLMs can be trained to provide responses that adhere to industry standards and guidelines, ensuring compliance and avoiding potential legal or reputational risks.
Final thoughts
The process of fine-tuning large language models (LLMs) has proven to be essential for achieving optimal performance in specific applications. The ability to adapt pre-trained LLMs to perform specialized tasks with high accuracy has unlocked new possibilities in natural language processing. As we continue to explore the potential of fine-tuning LLMs, it is clear that this technique has the power to revolutionize the way we interact with language in various domains.
