![]() ![]() The research and development (R&D) cycle for innovative small-molecule drugs faces many challenges, such as high cost-to-market, limited success in clinical trials, and long cycle times. Finally, several challenges and limitations of the current methods are summarized, with a view to potential future directions for AI-assisted drug discovery and design. After introducing the basic principles, alongside some application notes, of the various machine learning algorithms, the current state-of-the art of AI-assisted pharmaceutical discovery is discussed, including applications in structure- and ligand-based virtual screening, de novo drug design, physicochemical and pharmacokinetic property prediction, drug repurposing, and related aspects. This review provides a comprehensive portrayal of these machine learning techniques and of their applications in medicinal chemistry. ![]() Various machine learning approaches have recently (re)emerged, some of which may be considered instances of domain-specific AI which have been successfully employed for drug discovery and design. They need to be more secure, more stable and do a better job at rendering pages.Artificial intelligence (AI), and, in particular, deep learning as a subcategory of AI, provides opportunities for the discovery and development of innovative drugs. Browsers need to be better software, period. There are alternatives, such as Vivaldi and Brave, but most (including those two) are based on Chromium, so I'd just be getting a Chrome browser with a different UI. I've lost count of the number of times I've had to load a page in all three browsers, just to see if it works. IE also has a real annoying habit of sorting your folders of bookmarks alphabetically, rather than letting you sort them the way you want.ĭespite the fact that HTML is a relatively mature and simple language, it's amazing how differently some pages will behave. I have not considered IE 11 because of its lack of plugins, and since I use Windows 7, Edge is out of the question. For whatever reason, it has a real problem with graphics. Or it doesn't handle slideshows very well. So, I'll shut down the browser, click optimize memory, and I'm back to 35 percent used memory.įirefox also can be dog slow at loading pages, and it doesn't always load images. I'll watch the Wise Memory Optimizer slowly (and sometimes quickly) jump from 50 percent memory used to 70 percent in no time. This is especially true if my machine has been running for days and I have not restarted the browser. Issues with Firefoxīut Firefox is far from ideal. Well, if I leave Tweetdeck running for a few hours and come back, it's locked up. ![]() As you know, Google ended support for Tweetdeck as a stand-alone app, shifting to a plug-in for Chrome only. ![]() I have to hit the F5 button at least once and sometimes more before the page properly renders.Īnd I don't know where the fault lies here, but Tweetdeck on Chrome is broken for me and has been for some time. It will load it, and it's an unreadable mess. It frequently fails to render a page properly. One guy in Japan can get it working on Firefox, but all of Google's resources can't make it work on Chrome?Ĭhrome has another problem. Google, which you would think would have more smart people than the modest Mozilla Foundation (no offense guys, it's all about relative scale), has given up on ever getting vertical tabs to work in Chrome. There is a fantastic extension called Tree Style Tab that works wonders. In horizontal sacking, they get so crowded you can't read the title of the tab any more. You can have 30 tabs open, and every title is readable. It was also a memory hog until recently, and it frequently does not load and render pages right, forcing me to hit F5 more than once.Ĭurrently I use Firefox for one reason: vertical tab stacking. It doesn't load images well, and it is prone to crashing or slowing down.Ĭhrome: This browser can't do vertical tabs to save its life. And it often performs poorly on benchmarks and rendering tests.Įdge: This browser didn't have extensions until the Anniversary update, and the choice is very limited.įirefox: This is a memory pig that frequently sucks up all the RAM in my 16GB system. It has no third-party plug-in market like Firefox and Mozilla. Internet Explorer 11: It’s the most targeted browser for malware. Instead, they are all broken to one degree or another.
