Apa bedanya training, validasi, development dan test set ?

Dalam sebuah seminar/konferensi ilmiah, saya bertanya kepada pemateri: Kenapa data yang dipakai untuk validasi dan test sama? Menurut beliau, istilah validasi dan test dalam machine learning sama. Menurut saya ini salah. Data validasi tidak boleh dipakai untuk test (karena tentu saja, hasilnya akan lebih bagus). Data validasi sama dengan data development, keduanya, validation dan development, merupakan istilah yang sama untuk "tuning model" dari hasil training.
