With a total of 7 patents, Didari has made significant strides in utilizing artificial intelligence to enhance image recognition and classification processes.

Latest Patents

One of Didari's latest patents focuses on "Object discovery using an autoencoder." This innovation addresses a problem in supervised learning by employing patches to discover objects in unlabeled training images. The discovered objects are embedded in a pattern space, where an AI machine replaces manual entry steps of training with a machine-centric process. This includes clustering in both pixel and latent spaces, ultimately building a pattern space based on various losses derived from these clusters. The distance structure in the pattern space captures the co-occurrence of patterns, effectively identifying frequent objects such as human faces, bodies, animals, and vehicles from unorganized image data.

Another notable patent is centered on "Unsupervised representation learning and active learning to improve data efficiency." This invention tackles the issue of imbalanced big data by decoupling a classifier into a neural network for generating representation vectors and a classification model for operating on these vectors. The neural network is trained using an unsupervised algorithm, while the classification model utilizes a supervised active learning loop. This hybrid classifier not only reduces labor but also enhances efficiency in achieving accurate classification performance, even in cases of significant class imbalance.
