What is real Reality? AI might tell us

Last year I went to the National Gallery in London to see Francisco Goya’s exhibition. I did enjoy the painter’s mastery on giving human character to his portraits by balancing the relationship between the background, often solid colour, and the subject. Goya doesn’t draw a border between the two; he blurs the boundary so that the subject emerges from the background. Such simple operation gives a sense of the character’s personality; the balance of colours – and chiaroscuro – that gradually progress from the background to the the face and the body returns to me (the interpreter) the experience of the subjects’s personality.

Current research on AI is moving towards giving machines a sense of space, by teaching them what is space (as we do). Through Deep Learning machines are growing the sense of reality. They are developing a form of knowledge that is capable of understanding objects in real space, by means of image pixelation. In this article from MIT Technology Review it is described how machines are capable to detect physical objects via digital images; pixelation is the language they employ. The differential between the background and the given object is indeed in the focus of attention. On the opposite of the poetic skill Goya used to give a sense of the subject’s personality, the understanding of “border” is the key element used to teach machines space. The intention is to teach machines to “see”, and I suppose think, like us. Digital image pixelation is the vehicle that machines use to understand the real as we do.

What is the real?

Quoting Slavoj Žižek’s:Every field of “reality” is always-ready enframed, seen through an invisible frame. The parallax is not symmetrical, composed of two incompatible perspectives of the same X: there is an irreducible asymmetry between the two perspectives, a minimal reflexive twist. We do have two perspectives, we have a perspecive and what eludes it, and the other perspectives fills in this void of what we could not see from the first perspective“.

In other words we, human, don’t see things as our eyes do. There is a gap in between that constructs our sense of the real. As quoted from Žižek, there is a void in between that we fill with our imagination. Imagination is a form of expectation of the real, which is linked to our past experience that, in our mind, has been stored in the form of memory.

How can such a random and complex fluctuation be translated to a machine? What we call “real” is nonetheless a specific frame of our perception, which doesn’t make any distinction between digital and physical, as everything gets stored in our mind in the form of experience. It kinds of makes me think back to the Ridley Scott’s Blade Runner, which machines desperately need pictures to be acknowledged as humans.
