Questions and answers designated by tag: Image Classification

Given that I want to train a model to recognize plastic types correctly, 1. What should be the correct model? 2. How should the data be labeled? 3. How do I ensure the data collected represents a real-world scenario of dirty samples?

Monday, 23 March 2026 by Reuben Amedalor

To address the problem of training a machine learning model for the recognition of plastic types, especially within the context of real-world scenarios where samples may be dirty or contaminated, it is necessary to approach the problem with a comprehensive understanding of the requirements and constraints associated with both data and model choice. The process

How can I practice AutoML Vision without Google Cloud Platform (I don't have a credit card)?

Wednesday, 05 November 2025 by Fernando_Toscano

Practicing AutoML Vision without access to the Google Cloud Platform (GCP) due to the lack of a credit card or other constraints is a common situation for students and independent learners. While GCP's AutoML Vision provides a highly integrated, user-friendly interface for creating and deploying machine learning models for image classification, there are alternative approaches

Is there a type of training an AI model in which both the supervised and unsupervised learning approaches are implemented at the same time?

Thursday, 07 November 2024 by Preethi Parayil Mana Damodaran

The field of machine learning encompasses a variety of methodologies and paradigms, each suited to different types of data and problems. Among these paradigms, supervised and unsupervised learning are two of the most fundamental. Supervised learning involves training a model on a labeled dataset, where the input data is paired with the correct output. The

Are convolutional neural networks considered a less important class of deep learning models from the perspective of practical applications?

Friday, 09 August 2024 by Tomasz Ciołak

Convolutional Neural Networks (CNNs) are a highly significant class of deep learning models, particularly in the realm of practical applications. Their importance stems from their unique architectural design, which is specifically tailored to handle spatial data and patterns, making them exceptionally well-suited for tasks involving image and video data. This discussion will consider the fundamental

What are some examples of semi-supervised learning?

Tuesday, 27 February 2024 by Patricia Manuelita Izquierdo Sarmiento

Semi-supervised learning is a machine learning paradigm that falls between supervised learning (where all data is labeled) and unsupervised learning (where no data is labeled). In semi-supervised learning, the algorithm learns from a combination of a small amount of labeled data and a large amount of unlabeled data. This approach is particularly useful when obtaining

Why are deep neural networks called deep?

Friday, 18 August 2023 by Nguyen Xuan Tung

Deep neural networks are called "deep" because of their multiple layers, rather than the number of nodes. The term "deep" refers to the depth of the network, which is determined by the number of layers it has. Each layer consists of a set of nodes, also known as neurons, which perform computations on the input

How can one-hot vectors be used to represent class labels in a CNN?

Sunday, 13 August 2023 by EITCA Academy

One-hot vectors are commonly used to represent class labels in convolutional neural networks (CNNs). In this field of Artificial Intelligence, a CNN is a deep learning model specifically designed for image classification tasks. To understand how one-hot vectors are utilized in CNNs, we need to first grasp the concept of class labels and their representation.
