We present a method for learning sparse representations shared across multiple tasks. This method is a generalization of thewell-known single-task 1-norm regularization. It is based on a novel non-convex regularizer which controls the number of learnedfeatures common across the tasks. We prove ...

First, we extend the method from a 2-task space to an n-task space. This expands the dimensionality of the task interpolation, providing more tasks choice for subsequent convex combination interpolation. Second, in the multi-task space, we randomly select multiple tasks and combine them using ...

3.4. Multi convex decomposition – Figure 7 Having a learnable pipeline for a single convex object, we can now expand the expressivity of our model by repre- senting generic non-convex objects as compositions of con- vexes [66]. To achieve this task an encoder E outputs a low- 4 34 ...

The main components of Transformer are multi-head self-attention, position-wise feed-forward, and residual connection. The self-attention projects the input feature into three spaces: query, key, and value. By concatenating the multi-head attention, we can let the model learn more information. ...

Inverse multiobjective optimization provides a general framework for the unsupervised learning task of inferring parameters of a multiobjective decision making problem (DMP), based on a set of observed decisions from the human expert. However, the performance of this framework relies critically on the...
Finally, target detection task is formulated as a separation problem of low-rank, sparse, and structured sparse tensors, which is solved via an optimization algorithm based on ADMM and the fast t-SVD. In addition, the key parameters of the model can be selected appropriately through experiments...
