Intuitively, this function \"squashes\" a vector of unnormalized predictions, generating a probability for each of the 1000 classes (normalized predictions).\n\nThe unnormalized predictions vector is usually called [logits](https://developers.google.com/machine-learning/crash-course/glossary#logits).

Luckily for this visualization, the classes in ImageNet tend also to be organized by super-classes. Many dog breeds are in the indices 150 - 280, fish in 390 - 400 range, and fruits in the high 900 range.\n\nLet's inspect the logits for some golden retrievers, goldfish, and bananas:\n`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":281,"value":"dogsEl = ims([\n 'https://i.imgur.com/wUr8iq1.jpg', 'https://i.imgur.com/p2mewNT.jpg', 'https://i.imgur.com/NE7hVXb.jpg'])","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":288,"value":"{\n return drawChart(dogsEl.querySelectorAll('img')[0], 'conv_preds', null, 'dog 1 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":345,"value":"{\n return drawChart(dogsEl.querySelectorAll('img')[1], 'conv_preds', null, 'dog 2 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":348,"value":"{\n return drawChart(dogsEl.querySelectorAll('img')[2], 'conv_preds', null, 'dog 3 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":350,"value":"fishEl = ims([\n 'https://i.imgur.com/DPM3srH.jpg', 'https://i.imgur.com/DggGHu7.jpg', 'https://i.imgur.com/DKxWVoU.jpg'])","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":357,"value":"{\n return drawChart(fishEl.querySelectorAll('img')[0], 'conv_preds', null, 'goldfish 1 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":359,"value":"{\n return drawChart(fishEl.querySelectorAll('img')[1], 'conv_preds', null, 'goldfish 2 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":361,"value":"{\n return drawChart(fishEl.querySelectorAll('img')[2], 'conv_preds', null, 'goldfish 3 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":306,"value":"bananaEl = ims([\n 'https://i.imgur.com/C80YZFr.jpg', 'https://i.imgur.com/kxo5lwM.jpg', 'https://i.imgur.com/YbcFmdO.jpg'])","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":377,"value":"{\n return drawChart(bananaEl.querySelectorAll('img')[0], 'conv_preds', null, 'banana 1 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":381,"value":"{\n return drawChart(bananaEl.querySelectorAll('img')[1], 'conv_preds', null, 'banana 2 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":384,"value":"{\n return drawChart(bananaEl.querySelectorAll('img')[2], 'conv_preds', null, 'banana 3 logits');\n}","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":1036,"value":"md`# Try it on your webcam!\n\nClick the checkbox below to turn on the webcam and visualize these logits live.
