The problem is if you are familiar with Indian clothing (kurta is very similar to salwar) And since my dataset comprises of both the types of clothing, the program does not work well. Recommendation system, by learning the users' purchase history, a clustering model can segment users by similarities, helping you find like-minded users or related products. The VGG network architecture was introduced by Simonyan and Zisserman in their 2014 paper, Very Deep Convolutional Networks for Large Scale Image Recognition. I thought about other approaches too, like maybe using PCA on the features and then do the clustering (/classification), maybe use SVM, or even SOM (convolutional SOM, though I'm not sure I'd find much about it over the net). asked Oct 9 '18 at 12:58. singrium singrium.

Although it wouldn’t be able to tell me anything about the data (as it doesn’t know anything aside from the numbers it receives), it would give me a starting point for further study. Image or video clustering analysis to divide them groups based on similarities. Otherwise, it's simply caused by the model structure, and you might want to work on that. Update (03/07/2019): As Python2 faces end of life, the below code only supports Python3. So with image classification, we want to give labels to an input image based on some set of labels that we already have. What would be a good approach that would be quite easy to implement (in python or, to be even more specific, in pytorch)? but That does not seem to have much effect. 3. Usage. In unsupervised classification, we group the sample images into clusters of images having similar properties. In supervised classification, we select samples for each target class.
