Tensorflow Image Classification with Your Own Dataset Oct 31, 2019 · Training. As a base model for transfer learning, we’ll use MobileNet v2 model stored on TensorFlow Hub. This model has advantages to be able to work on Mobile applications. How to use Dataset in TensorFlow - Towards Data Science dataset = tf.data.Dataset.from_tensor_slices (x) We can also pass more than one numpy array, one classic example is when we have a couple of data divided into features and labels features, labels = (np.random.sample ( (100,2)), np.random.sample ( (100,1))) dataset = tf.data.Dataset.from_tensor_slices ( (features,labels)) From tensors How to get the label distribution of a `tf.data.Dataset` efficiently? The naive option is to use something like this: import tensorflow as tf import numpy as np import collections num_classes = 2 num_samples = 10000 data_np = np.random.choice(num_classes, num_samples) y = collections.defaultdict(int) for i in dataset: cls, _ = i y[cls.numpy()] += 1

How to filter Tensorflow dataset by class/label? | Data Science and ... Hey @bopengiowa, to filter the dataset based on class labels we need to return the labels along with the image (as tuples) in the parse_tfrecord() function. Once that is done, we could filter the required classes using the filter method of tf.data.Dataset. Finally we could drop the labels to obtain just the images, like so:
