Beginner Guide to Building a Hate Speech Classifier with BERT

2025-07-08T13:54:15+00:00

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 process of building your OWN speech classifier using a well-known transformer model, BERT. This article guides you to a beginner-friendly beginning in modeling and machine learning. [...]

Launching an Amazon EC2 Instance using Terraform

2025-07-17T00:33:56+00:00

What's up, Dojos! This is your first step on automating your cloud infrastructure by launching an EC2 Instance using Terraform!  Efforts from various cloud providers such as AWS made managing your configurations manageable and easy by the use of their Management Consoles. With AWS, launching an EC2 instance, setting up IAM configurations, and VPC provisioning have never been easier within their console. But what if you have to configure large amounts of resources? Provisioning your projects are like a walk in the park, but if you’re managing an application or a business that caters to thousands to millions of customers [...]

Simplifying DNS Management: How to Transfer Your Domain’s DNS from GoDaddy to Amazon Route 53

2025-06-29T10:45:34+00:00

  If you have ever tried to create a website and wanted it to be accessible through a custom web address, then you have already touched the basics of DNS, or Domain Name System. DNS is what connects your domain name to the actual server where your website lives. It plays a critical role in making sure your site is reachable, fast, and secure for users around the world. Many website owners start by registering their domain with a provider like GoDaddy. This works well for buying and setting up a domain quickly. However, as your project or business grows, [...]

Why I Chose AWS Lambda to Power My App’s Cloud Logic

2025-06-27T09:40:37+00:00

For this article, I will demonstrate how I used AWS Lambda as an all-around backend system for a mock-up mobile application I developed for my Design subject in school. The mobile application is an IoT application that integrates communication between a mobile device and a handheld barcode scanner using a Bluetooth module. It also includes security functions, such as code decryption and user statuses. For the dependencies, I used flutter_blue, get, and http. The list below indicates the use cases of AWS Lambda for my mobile application. I hope, by the end of this article, you will know how to [...]

What is Area Under the ROC Curve (AUC) in Machine Learning?

2025-07-01T02:38:28+00:00

Area Under the ROC Curve (AUC) Cheat Sheet AUC, short for Area Under the Curve of the Receiver Operating Characteristic (ROC), is a metric that evaluates how well a model can differentiate between different classes. A performance metric primarily used for binary classification models. Ranges from 0 to 1: 1: Perfect model. 0.5: Model performs no better than random guessing. 0: Model inversely ranks positives and negatives. Accurate Outcomes True Positive (TP): The model predicted 1, which matches the actual result. True Negative (TN): The model predicted 0, and the real outcome was also 0. Misclassified Outcomes False Positive (FP): [...]

What is BiLingual Evaluation Understudy (BLEU) Score for Machine Translation?

2025-06-25T01:15:03+00:00

BiLingual Evaluation Understudy (BLEU) Score Cheat Sheet BLEU (BiLingual Evaluation Understudy) is a corpus-level metric designed to automatically evaluate the quality of machine-generated text, most commonly in machine translation (MT). It compares n-gram overlap between the machine’s output and one or more human reference translations. Introduced by Papineni et al. (2002), BLEU became the first automated metric to correlate highly with human judgments in large-scale MT evaluations. It remains a widely used baseline for evaluating machine-generated text. Common Use Cases The BLEU score is widely used in natural language processing tasks that require comparing machine-generated text to human-written references. Its primary [...]

What is RLHF – Reinforcement Learning from Human Feedback?

2025-06-24T05:52:27+00:00

What is Reinforcement Learning from Human Feedback (RLHF)? A technique to improve AI models using human feedback to guide learning. Builds on reinforcement learning, where AI learns by trial and error to achieve goals. Uses human opinions to determine good or bad outputs, enhancing traditional reward systems. How RLHF Works Data Collection: AI generates multiple outputs (e.g., answers or text snippets). Humans provide feedback by ranking or comparing outputs (e.g., which is better or more helpful). Supervised Fine-Tuning: Model is trained with human feedback to produce preferred outputs. Establishes a baseline for good responses. Building a Reward Model: Creates a [...]
