Abstract: A method for allocating perishable products based on machine learning, includes using a sales estimation model to evaluate estimated sales of a plurality of perishable products in a predetermined period, using a rating model to calculate a predetermined rate of the plurality of perishable products in the predetermined period according to the estimated sales, using an allocation model to adjust an allocation ratio of the plurality of perishable products in a plurality of marketing channels according to the estimated sales and the predetermined rate if a current rate is lower than the predetermined rate, and determining the numbers of perishable products allocated to the plurality of marketing channels according to the allocation ratio.

Abstract: A rate adjustment method includes a rate estimation model generating a plurality of estimated rates according to a plurality of training data, a revenue estimation model generating an estimated revenue according to the plurality of estimated rates, updating the rate estimation model according to the estimated revenue to generate an updated rate estimation model, and inputting a plurality of current data into the updated rate estimation model to update the plurality of estimated rates.

Abstract: A horizontal pyrolysis furnace has a kiln and two barrels. The two barrels are respectively a processing barrel rotatably disposed in the kiln and a takeover barrel detachably connected with the processing barrel. Each one of the two barrels has a gate assembly and at least one spiral guiding plate. The gate assembly of the processing barrel is mounted on an end of the processing barrel, and extends out from the kiln. The two gate assemblies of the two barrels are detachably connected such that the two barrels are able to rotate synchronously. The at least one spiral guiding plate is fixed on an inner surface of one of the two barrels, and the spiral guiding plates of both barrels have an identical helical direction.

Abstract: A circuit board includes an induction coil, a ground cable, and an audio signal cable. The induction coil and the audio signal cable are respectively allocated at the two sides of the ground cable. The induction coil and the audio signal cable are spaced a predetermined distance apart. The predetermined distance is equal to or greater than an effective inductive distance of the induction coil.
