Supervised Image Classification. Classification of Rice Plant Image…


Image Classification is a process/task used for extracting information classes from an image or, in other words, it is a process of classifying an image based on its visual content. Tensorflow Image Classification is referred to as the process of computer vision. Get the data from an external source in our case is rice plant disased leaf images. Make sure that your image's data set correctly labelled. So you can understand how no examples are there in the dataset.

A simpler path to better computer vision


Before a machine-learning model can complete a task, such as identifying cancer in medical images, the model must be trained. Training image classification models typically involves showing the model millions of example images gathered into a massive dataset. To avoid these pitfalls, researchers can use image generation programs to create synthetic data for model training. But these techniques are limited because expert knowledge is often needed to hand-design an image generation program that can create effective training data. Researchers from MIT, the MIT-IBM Watson AI Lab, and elsewhere took a different approach.

MaxVit -- Multi Axis Vision Transformer


Over the past few years, there has been a lot of competition of iterative improvements based on Convolution Nets and the relatively recent Transformer in terms of being the best architecture on the standard Image vision tasks. In the paper published in ECCV 2022, Researchers in Google Research and UT Austin introduce MaxVit. MaxVit -- Multi Axis Vision Transformer aims to combine the best features of both Convolution and Transformer by solving the issue related to global attention in transformers. We will first discuss the set of Vision Task for which these methods are applied .A typical vision task involved taking the input of 2D image and taking the RGB matrix format to your Neural network architecture. Image Classification is the problem of assigning labels to images from a fixed set of categories.

Neural Rendering: A Brief Overview -


Neural rendering uses deep neural networks to create new images and video from existing scenes. The camera angles, lighting, and other details can be rendered into a realistic model of a 3D scene. In addition, neural rendering of existing images and videos can be used to generate synthetic data. Why it matters: Traditional 3D graphic rendering needs a model with a polygon mesh describing shape, color, and textures, as well as the lighting and camera position. Neural rendering simulates camera physics to separate the 3D scene from the camera capture process, making it easier to create new images from existing images and videos with consistency.

Text and Image Classification for Craigslist using GloVe and MobileNet -- Transfer Learning


Craigslist, is an American Classified Advertisements website having various sections about housing, jobs, services (beauty, legal, health, etc.), and products for sale. Anyone can list a product or service on Craigslist for free and those interested can contact the poster. However, there are many listings on Craigslist that are not properly classified and are posted in incorrect sections. A particular category on the website that is of interest for us is the'Bikes' Section. Just like all other sections on the website, the'Bikes' Section of Craigslist, has many listings that do not belong there.

Image Classification with No Data?


You want to build a Machine learning model without much data? Machine learning is known to be data-hungry while gathering and annotating data requires time and is expensive.

Face Recognition as Image Classification


Image classification has been one of the most worked on domains in the field of deep learning. Ever since CNNs were introduced there have been continual improvements in learning Algorithms and these effects were only magnified in the past decade or so with powerful GPUs available at lower prices and the increased accessibility of cloud based computing platforms like Google Colab. Today I'll be going through the project i worked on for my Machine Intelligence Course: Face Detection using CNNs and its variations. We used the famous lfw dataset and imported it from kaggle. Some things to keep in mind, we used a kernel of size 3x3 (gave us accurate results and helped by not adding padding layers thus keeping computation in check), we also Max Pooling Layers of 2x2 with a stride of 2. We kept stride as 1 for kernels as our accuracy didn't improve much.

Top 5 Interview Questions on Multi-modal Transformers


This article was published as a part of the Data Science Blogathon. Until recently, developing new, improved transformers specifically for a single modality was common practice. However, to tackle real-world tasks, there was a pressing need to develop multi-modal transformers models. Multi-modal transformers models are the type of models that employ the process of learning representations from different modalities using a single model. Input modalities for machine learning include photos, text, audio, etc. Multi-modal learning models the combination of different modalities of data, which often arise in real-world applications.

U.S. Expands Bans of Chinese Security Cameras, Network Equipment WSJD - Technology

The Federal Communications Commission voted 4-0 to ban sales of new telecom and surveillance equipment made by several Chinese companies, arguing that their ownership and practices threaten U.S. national security. The rule change affects 10 companies already subject to other restrictions and prohibits them from marketing or importing new products. The FCC made its order public Friday. The latest order stops short of requiring U.S. equipment buyers to remove items they have previously purchased or stripping authorizations for electronics models that already exist. A spokesman for Hikvision said the FCC's decision won't protect U.S. national security, "but will do a great deal to make it more harmful and more expensive for U.S. small businesses, local authorities, school districts, and individual consumers."

PhD student improves image classification with just one extra line of code - Informatics Institute


Imagine a large number of medical scans from which doctors want to know which ones show a tumor and which ones don't. Quite probably the training data contain many more scans without a tumor than with a tumor. When an automatic image classification system is trained on such a biased dataset, and no extra measures are taken, the chances are high that it under diagnoses tumors, which of course is undesirable. Generally speaking, the less a particular example appears in a dataset, the more it is ignored by current day machine learning systems. And as many data sets in practice are out of balance, many applications unfairly ignore data classes that only contain a few examples.
