The invention discloses a method and an apparatus for updating parameters of a multi-task model. The method includes: obtaining a training sample set, in which the training sample set comprises a plurality of samples and a task to which each sample belongs; putting each sample into a corresponding sample queue sequentially according to the task to which each sample belongs; training a shared network layer in the multi-task model and a target sub-network layer of tasks associated with the sample queue with samples in the sample queue in case that the number of the samples in the sample queue reaches a training data requirement, so as to generate a model parameter update gradient corresponding to the tasks associated with the sample queue; and updating parameters of the shared network layer and the target sub-network layer in a parameter server according to the model parameter update gradient.

A method and an apparatus for generating a shared encoder are provided, which belongs to a field of computer technology and deep learning. The method includes: sending by a master node a shared encoder training instruction to child nodes, so that each child node obtains training samples based on a type of a target shared encoder included in the training instruction; sending an initial parameter set of the target shared encoder to be trained to each child node after obtaining a confirmation message returned by each child node; obtaining an updated parameter set of the target shared encoder returned by each child node; determining a target parameter set corresponding to the target shared encoder based on a first preset rule and the updated parameter set of the target shared encoder returned by each child node.

A vertical ring magnetic separator for de-ironing of coal ash comprises a rotating ring (), an inductive medium (), an upper iron yoke (), a lower iron yoke (), a magnetic exciting coil (), a feeding opening (), a tailing bucket () and a water washing device (). The feeding opening () is used for feeding the coal ash to be de-ironed, and the tailing bucket () is used for discharging the non-magnetic particles after de-ironing. The upper iron yoke () and the lower iron yoke () are respectively arranged at the inner and outer sides of the lower portion of the rotating ring (). The water washing device () is arranged above the rotating ring (). The inductive medium () is arranged in the rotating ring (). The magnetic exciting coil () is arranged at the periphery of the upper iron yoke () and the lower iron yoke () so as to make the upper iron yoke () and the lower iron yoke () to be a pair of magnetic poles for generating a magnetic field in the vertical direction, wherein the inductive medium () is layers of steel plate meshes, each steel plate mesh is woven by wires, and ridge-shape sharp corners are formed at the edges of the wires. A method for magnetically separating and de-ironing of coal ash, utilizes the vertical ring magnetic separator for de-ironing of coal ash. By adopting the vertical ring magnetic separator and the method of magnetic separation for de-ironing, the de-ironing efficiency is improved by at least 20%.

A method for manufacturing breakable capsules () that are useful for incorporating into a tobacco product (), such as smoking articles and smokeless tobacco products, is provided. The method comprises forming a plurality of droplets comprising a core composition and a coating composition. The coating composition comprises a material that gelates in contact with a multivalent ion. The method also comprises introducing the plurality of droplets in a first aqueous solution having a first concentration of a first multivalent ion such that the coating composition of the plurality of droplets gelates to form a plurality of raw capsules. The method further comprises introducing the plurality of raw capsules in a second aqueous solution having a second concentration of a second multivalent ion, wherein the second concentration is higher than the first concentration, such that the coating composition of the plurality of raw capsules hardens to form a plurality of breakable capsules ().
