Jr. Software Developer Small-Business (50 or fewer emp.) 2/15/2023 ""ConvNetJS is known for its useful features and groundbreaking Deep Learning JavaScript library."" 4.5/5 What do you like best about ConvNetJS? ConvNetJS is a library built from Javascript that enables users to train Deep Learning models implemented as Neural Networks when loaded into a web browser. It is an experimental reinforcement learning module derived from Deep Q Learning and can reach its full potential without additional compilers, programs, graphics processing units (GPUs), or configurations. The source code is published under the MIT License on GitHub, where multiple AI groups collaborate to improve this deep learning tool. ConvNetJS trains and specifies AI-based convolutional networks for image processing. Review collected by and hosted on G2.com. What do you dislike about ConvNetJS? Despite its many benefits, ConvNetJS can be challenging for novices to master. It has a slow processing time, which is a con, but if you've used it, you should stick with it. It should receive a more significant amount of praise than it does. Review collected by and hosted on G2.com. What problems is ConvNetJS solving and how is that benefiting you? ConvNetJS is a JavaScript library for browser-based CNN training and execution, popular with experienced developers and open-source. It is regularly expanded and improved, and its functionality and expert craftsmanship have earned it high praise. It deserves more credit than it receives, and once you've used it, you might as well rally behind it. Review collected by and hosted on G2.com.

As a frontend engineer, this library is a saver to train models using javascript or node js. We have been using this to train models' best work at the frontend side, with no dependency on the server-side application. A quick way to train the model. Easy to integrate and less time to bootstrap. It gives the flexibility to execute the training model in a choice of browser, we have done it using Chrome. Review collected by and hosted on G2.com. What do you dislike about ConvNetJS? Sometimes it takes time to load on the browser, which can be improved. Mostly works or is compatible with all the latest versions of the browser but. I faced an issue while loading it on Microsoft edge. At times faced challenges on the documentation side; not every junior team member could understand the documentation and start building. Strong work can be done to improve community support or documentation. Debugging is also a challenge we have faced; we did find any easy way to do it. Review collected by and hosted on G2.com. What problems is ConvNetJS solving and how is that benefiting you? In our case, we have trained an ML model using ConvNetJS and run it through the browser or node js. This helped us to train and execute models having no zero knowledge of backend technologies. Also, the training set can be easily built up and retrain model is also done in a quick time. Good initiate to execute the models at frontend using a browser Review collected by and hosted on G2.com.

ConvNetJS is an excellent library tool for JavaScript in order to train deep learning models (neural networks) completely in your browser. It is very easy to use and you open an eyelash and you are training. No software requirements, no compilers, no installations, no GPU, no effort. ConvNetJS uses JavaScript as its core to execute deep learning models, and also in its personal and favorite browsers. Review collected by and hosted on G2.com. What do you dislike about ConvNetJS? ConvNetJS is a very useful and very good tool, we can say that its biggest disadvantage is that it is difficult to manage and lacks simplicity for beginners who want to use it, because in order to use this tool must have knowledge in the area. We can also say that probably another disadvantage that would disfavor using ConvNetJS, this in its processing is sometimes slower than in other tools equal to this. Review collected by and hosted on G2.com. Recommendations to others considering ConvNetJS: I like to use this tool a lot for the JavaScript library, it is excellent for encoding encrypted files. This resolves the need for file encryption, as well as the debugging of JavaScript. We can recommend 100% this tool Review collected by and hosted on G2.com. What problems is ConvNetJS solving and how is that benefiting you? It is the tool that we need to train neural networks, it can be applied perfectly in the recognition of patterns or to complement other functions of Artificial intelligence.
