Seperti yang diminta oleh ramai daripada anda, kami kini sedang bekerja keras untuk menyediakan contoh beberapa kod dan pakej pembelajaran mesin kami.
TensorFlow, PyTorch, Keras, Numpy, Pandas dan banyak lagi pakej .NET untuk memulakan di dalam cTrader.
Misi kami adalah untuk memudahkan Pembelajaran Mesin di dalam cTrader untuk semua orang.
Selamat memburu!
*** Kod ini tidak melakukan sebarang dagangan (ia hanya mencetak data dan sebagainya). Ia hanyalah kod contoh bagaimana anda boleh mula mencipta model AI anda sendiri menggunakan pakej Pembelajaran Mesin kami.
