Azure AI Language’s pre-built sentiment analysis feature is specifically designed for this scenario. It provides out-of-the-box sentiment detection (positive, negative, neutral, mixed) without the need for custom model training, making it the most straightforward and cost-effective option for analyzing large volumes of text like product reviews.

Classification is a type of supervised machine learning used to predict a categorical label or class. ‘Spam or not spam’ is a classic binary classification problem. Predicting a dollar amount (sales) or a continuous value (temperature) is regression, and grouping customers is an unsupervised clustering task.

Azure AI Vision’s Custom Vision service is designed for this exact scenario. It allows users to create custom image classifiers (e.g., ‘fracture’ vs. ‘no fracture’) using their own, limited datasets through a user-friendly, code-optional interface. This is more suitable than a general pre-built model or a service meant for text.

This scenario describes a fairness issue stemming from bias in the AI model. The most common source of such bias is the historical training data. If past hiring data reflected a human bias favoring certain universities, the model learned and perpetuated that pattern, leading to unfair outcomes.

Unsupervised learning is used to find patterns, groupings, or structures in data that has no pre-existing labels. Since the company is looking for ‘hidden patterns’ in raw sensor data without known failure labels, unsupervised learning techniques like anomaly detection or clustering are the appropriate starting point.

Conversational Language Understanding (CLU), part of Azure AI Language, provides a dedicated ‘prediction overview’ and performance dashboard. It allows developers to review utterances that the model was less confident about, inspect misclassified examples, and actively learn from this data to improve the chatbot’s intent recognition and entity extraction.

Inclusiveness is a core pillar of responsible AI focused on designing and developing systems that empower everyone, including people with disabilities and those from diverse backgrounds. It addresses potential barriers in interaction, input, and output to ensure the technology benefits a broad user base.

Phrase lists allow you to provide the speech-to-text service with context-specific words or phrases (like product names, technical terms, or common slang) that might be pronounced with an accent. This significantly improves accuracy for specialized vocabulary that a generic model might misinterpret, making it ideal for this scenario.

This describes overfitting. It occurs when a model learns the noise, details, and random fluctuations in the training data to such a degree that it negatively impacts its performance on new data. It’s often a result of an overly complex model that essentially ‘memorizes’ the training set instead of learning the generalizable patterns.
