Image Classification: Counting Part II

#artificialintelligence

In Part I, we saw a few examples of image classification. In particular counting objects seemed to be difficult for convolutional neural networks. After sharing my work on the fast.ai Now we can create a learner and train it on this new dataset. Wow! Look at that, this time we're getting 100% accuracy.


Ladder Networks for Semi-Supervised Hyperspectral Image Classification

arXiv.org Machine Learning

We used the Ladder Network [Rasmus et al. (2015)] to perform Hyperspectral Image Classification in a semi-supervised setting. The Ladder Network distinguishes itself from other semi-supervised methods by jointly optimizing a supervised and unsupervised cost. In many settings this has proven to be more successful than other semi-supervised techniques, such as pretraining using unlabeled data. We furthermore show that the convolutional Ladder Network outperforms most of the current techniques used in hyperspectral image classification and achieves new state-of-the-art performance on the Pavia University dataset given only 5 labeled data points per class.


Convolutional neural network with The Simpsons

#artificialintelligence

Convolutional Neural Network(CNN) is a type of neural network especially useful for image classification tasks. I applied CNN on thousands of Simpsons images training the classifier to recognise 10 characters from the TV show with an accuracy of more than 90 percent.


Deep Learning: CNNs for Visual Recognition

#artificialintelligence

Learn Convolutional Neural Networks for Visual Recognition and the building blocks and methods associated with them. Deep Learning has made some huge and significant contributions and it's one of the mostly adopted techniques in order to drive insights from your data nowadays. Convolutional neural networks have gained a special status over the last few years as an especially promising form of deep learning. Rooted in image processing, convolutional layers have found their way into virtually all subfields of deep learning, and are very successful for the most part. Convolutional Neural Networks are very similar to ordinary Neural Networks: they are made up of neurons that have learnable weights and biases.


Identifying Medical Diagnoses and Treatable Diseases by Image-Based Deep Learning

#artificialintelligence

Artificial intelligence (AI) has the potential to revolutionize disease diagnosis and management by performing classification difficult for human experts and by rapidly reviewing immense amounts of images. Despite its potential, clinical interpretability and feasible preparation of AI remains challenging.
