What is ROUGE Metrics – Recall-Oriented Understudy for Gisting Evaluation?

Recall-Oriented Understudy for Gisting Evaluation (ROUGE) Cheat Sheet ROUGE is a family of metrics designed to assess the similarity between machine-generated text (candidate) and human-written reference text (ground truth) in NLP tasks like text summarization and machine translation. Measures how well generated text captures key information and structure from reference text, emphasizing recall (proportion of relevant information preserved). Score Range: 0 to 1, where higher scores indicate greater similarity between candidate and reference texts. [...]

We asked ourselves a simple question: Can you build a chatbot without using any paid API at all? Most tutorials on AI chatbots start the same way: "First, grab your OpenAI API key and add your credit card..." But what if you don't have one? Or don't want to use [...]

Beginner Guide to Building a Hate Speech Classifier with BERT

You've seen the warnings: "This comment may violate our community guidelines," or you've watched online posts or videos get flagged and removed due to their hate speech content. This means that the platform is already using models to detect harmful content. However, have you ever questioned how these models work? How are these models able to understand human sarcasm, cultural slang, and even multilingual language in one sentence? In this guide, we'll walk through the [...]

Motoko vs Solidity: A Developer-Centric Comparison

Motoko vs Solidity: A Developer-Centric Comparison A New Era in Smart Contract Development Innovative contract development has evolved significantly over the past decade. With the rise of decentralized finance (DeFi), non-fungible tokens (NFTs), and a growing ecosystem of decentralized applications, Solidity has long been the standard for writing contracts on the Ethereum Virtual Machine (EVM). It introduced developers to a new paradigm: trustless systems, which do not require trust between parties, programmable money, and [...]

What is BERTScore – Bidirectional Encoder Representations from Transformers Score?

BERTScore (Bidirectional Encoder Representations from Transformers Score) Cheat Sheet BERTScore is an effective evaluation metric that looks beyond surface-level word matching to assess the meaning behind the generated text. Instead of counting overlapping words like traditional metrics such as BLEU or ROUGE, BERTScore taps into the power of pre-trained transformer models (like BERT) to compare the semantic similarity between tokens in the generated output and a reference sentence. It does this by calculating the [...]
