I’m working on a mid-sized TypeScript project and running into a weird issue with type narrowing. Inside a callback function (specifically inside a .map()), TypeScript refuses to narrow a union type even though I’ve added all the checks. Outside the callback it works fine. Is this a known limitation, or …

**Features:** * Retrieves the differentiating bit of a key with respect to the previous one and stores only this position in the index. * With at most one single disk read, assuming the index is in memory, it determines whether the key exists or not. * The index is always …

When my app loads I need to establish the membership "status" of a user. Their "status" will determine how the app behaves. Do I query the database for the "status" value each time the app loads, or can it be sourced from cache? The "status" could change for a user, …

In the [last article](https://www.daniweb.com/programming/computer-science/tutorials/542973/benchmarking-deepseek-r1-for-text-classification-and-summarization#post2300447), I explained how you can use the [DeepSeek-R1-Distill-Qwen-32B](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Qwen-32B) model for text classification and summarization problems. In this article, we will use the [DeepSeek-R1-Distill-Llama-70b](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Llama-70B) for the same tasks. Following results from the [DeepSeek-AI's official paper](https://arxiv.org/pdf/2501.12948) show that `DeepSeek-R1-Distill-Llama-70b` outperform the other distilled models on 4 out of …

On November 20, 2024, OpenAI updated its GPT-4o model, claiming it is more creative and accurate on several benchmarks. In this article, I compare the GPT-4o November update with the previous version (August update) for text summarization and classification tasks. By the end of this article, you will see whether …

Large language models (LLMS) are trained to predict the next token (set of characters) following an input sequence of tokens. This makes LLMs suitable for unstructured textual responses. However, we often need to extract structured information from unstructured text. With the Python [LangChain](https://www.langchain.com/) module, you can extract structured information in …

As a data scientist, I have extensively used the Hugging Face library for processing unstructured data such as images, text, and audio. My previous blogs have covered various transformer models for these types of data. Lately, however, I discovered that Hugging Face also provides transformer models for tabular data. One …

On March 4, 2024, [Anthropic](https://www.anthropic.com/) launched the [Claude 3 family of large language models](https://www.anthropic.com/news/claude-3-family). Anthropic claimed that its Claude 3 Opus model outperforms GPT-4 on various benchmarks. Intrigued by Anthropic's claim, I performed a simple test to compare the performances of Claude 3 Opus, [Google Gemini Pro](https://deepmind.google/technologies/gemini/#introduction), and [OpenAI's GPT-4](https://openai.com/research/gpt-4) …

On February 21, 2024, Google released [Gemma](https://ai.google.dev/gemma), a family of state-of-the-art open-source large language models (LLMs).
