Recently, a team of researchers from Facebook AI and Tel Aviv University proposed an AI system that solves the multiple-choice IQ test , Raven’s Progressive Matrices. The proposed AI system may be a neural network model that mixes multiple advances in generative models, including employing multiple pathways through an equivalent network.

Raven’s Progressive Matrices, also referred to as Raven’s Matrices, are multiple-choice intelligence tests. The test is employed to live abstract reasoning and is considered a non-verbal estimate of fluid intelligence.

In this test, an individual tries to end the missing location during a 3X3 grid of abstract images. consistent with the researchers, there are various similar researches, where the most focus entirely on choosing the proper answer out of the varied choices. However, during this research, the researchers focussed on generating an accurate answer given the grid, without seeing the alternatives .

Behind the Model
As mentioned above, the neural network model may be a combination of varied advances in generative models, including employing multiple pathways within an equivalent network. It uses the ‘reparameterisation’ trick along two pathways so as to form their encoding compatible, which are a dynamic application of variational losses and a posh perceptual loss which is linked with a selective backpropagation procedure.

In this research, the researchers considered the task of generating an accurate answer to a Raven Progressive Matrix (RPM) sort of IQ test . during this test, each query includes eight images that are placed on a 3X3 grid size. The task of this test is to make the missing 9th image, such it matches the patterns of the rows and columns of the grid.

The neural net model recognises the right answer out of the eight alternatives by encoding each image and aggregating these encodings along rows and columns.

The architecture of the AI model is especially composed of three different pathways:

1.Reconstruction: The reconstruction pathway provides supervision that’s more accessible to the network when beginning to train.
2.Recognition: the popularity pathway shapes the representation during a way that creates the semantic information more explicit.
3.Generation: The generation pathway relies on the embedding of the visual representation from the primary task, and on the semantic embedding obtained with the help of the second, and maps the semantic representation of a given query to a picture .

The researchers stated, “In problems during which the answer space is complex enough, the power to get an accurate answer is that the ultimate test of understanding the question since one cannot extract hints from any of the potential answers. Our work has been the primary to deal with this task within the context of RPMs.”
