A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Dealing with categorical data is an essential part of data preprocessing in many machine learning tasks. Fortunately, encoding categorical data efficiently helps enhance the performance of machine ...

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new path for storing far more data in the same physical space. A research team led ...
