Method of training a neural network to reflect emotional perception and related system and method for categorizing and finding associated content
A property vector representing extractable measurable properties, such as musical properties, of a file is mapped to semantic properties for the file. This is achieved by using artificial neural networks “ANNs” in which weights and biases are trained to align a distance dissimilarity measure in property space for pairwise comparative files back towards a corresponding semantic distance dissimilarity measure in semantic space for those same files. The result is that, once optimised, the ANNs can process any file, parsed with those properties, to identify other files sharing common traits reflective of emotional-perception, thereby rendering a more liable and true-to-life result of similarity/dissimilarity. This contrasts with simply training a neural network to consider extractable measurable properties that, in isolation, do not provide a reliable contextual relationship into the real-world. |

Early runtime detection and prevention of ransomware
Various automated techniques are described herein for the runtime detection/neutralization of malware executing on a computing device. The foregoing is achievable during a relatively early phase, for example, before the malware manages to encrypt any of the user's files. For instance, a malicious process detector may create decoy file(s) in a directory. The decoy file(s) may have attributes that cause such file(s) to reside at the beginning and/or end of a file list. By doing so, a malicious process targeting files in the directory will attempt to encrypt the decoy file(s) before any other file. The detector monitors operations to the decoy file(s) to determine whether a malicious process is active on the user's computing device. In response to determining that a malicious process is active, the malicious process detector takes protective measure(s) to neutralize the malicious process. |
