The transducer model is a deep learning model, and is a model for improving the training speed of the model by using an attention mechanism. As with RNN networks, the transducer model is used to process sequential input data, such as natural language, for translation and text summarization tasks. Unlike RNN networks, the transducer model does not necessarily process data in order.

In this embodiment, the step analysis content obtained by the step derivation model output is realized as text content of the geometric topic solving step, and therefore, the step analysis content is converted from text content to a conversion graph by inputting the step analysis content into the graph generation model. The conversion graph refers to a graph corresponding to a problem solving step in the step analysis content, for example: the geometric subject is the sum of the areas corresponding to the cubes with the calculated edge length of 2, the step analysis content is obtained by outputting a step deduction model, namely the cubes are unfolded to obtain a plane unfolding diagram corresponding to six faces, the sum of the areas corresponding to 6 squares is the sum of the areas corresponding to the cubes, the problem solving step in the step analysis content is that the cubes are unfolded to obtain the plane unfolding diagram corresponding to six faces, and the converted diagram is output to be the plane unfolding diagram corresponding to the cubes after inputting the pattern generating model.

In this embodiment, a Text To Image (TTI) model (e.g., attention deficit generating network (Attention Generative Adversarial Networks, attnGAN) or Fuse stream model) is used as the pattern generation model.

Wherein, the AttnGAN network refers to: the countermeasure generation network (Generative Adversarial Networks, GAN) is a generation type network employing countermeasure learning, and the GAN network structure includes an image generator and a discriminator, and the principle is that the generated image is made to approach the reference image by training the generator. During training, the accuracy of the discriminator and thus the generator is higher. The attention countermeasure generating network is based on the GAN network, so that higher attention can be given to corresponding words in the text when the image is generated, the quality and the relevance of the generated image are improved, and the image with fine granularity is generated.

Fuse stream: in TTI tasks, the parameters of the model are often pre-trained using contrast learning (Constractive Learning), a process abbreviated CLIP. This process may allow a faster convergence speed and a better starting point for the model. The Fuse stream model is a method that combines CLIP and GAN networks.

Typically, the front camera is disposed on the front panel of the terminal and the rear camera is disposed on the rear surface of the terminal. In some embodiments, the at least two rear cameras are any one of a main camera, a depth camera, a wide-angle camera and a tele camera, so as to realize that the main camera and the depth camera are fused to realize a background blurring function, and the main camera and the wide-angle camera are fused to realize a panoramic shooting and Virtual Reality (VR) shooting function or other fusion shooting functions. In some embodiments, camera assembly 1306 may also include a flash. The flash lamp can be a single-color temperature flash lamp or a double-color temperature flash lamp. The dual-color temperature flash lamp refers to a combination of a warm light flash lamp and a cold light flash lamp, and can be used for light compensation under different color temperatures.

The audio circuit 1307 may include a microphone and a speaker. The microphone is used for collecting sound waves of users and environments, converting the sound waves into electric signals, and inputting the electric signals to the processor 1301 for processing, or inputting the electric signals to the radio frequency circuit 1304 for voice communication. For purposes of stereo acquisition or noise reduction, a plurality of microphones may be provided at different portions of the terminal 1300, respectively. The microphone may also be an array microphone or an omni-directional pickup microphone. The speaker is then used to convert electrical signals from the processor 1301 or the radio frequency circuit 1304 into sound waves. The speaker may be a conventional thin film speaker or a piezoelectric ceramic speaker. When the speaker is a piezoelectric ceramic speaker, not only the electric signal can be converted into a sound wave audible to humans, but also the electric signal can be converted into a sound wave inaudible to humans for ranging and other purposes. In some embodiments, the audio circuit 1307 may also comprise a headphone jack.

A power supply 1308 is used to power the various components in terminal 1300. The power source 1308 may be alternating current, direct current, a disposable battery, or a rechargeable battery. When the power source 1308 comprises a rechargeable battery, the rechargeable battery may be a wired rechargeable battery or a wireless rechargeable battery. The wired rechargeable battery is a battery charged through a wired line, and the wireless rechargeable battery is a battery charged through a wireless coil. The rechargeable battery may also be used to support fast charge technology.

In some embodiments, terminal 1300 also includes one or more sensors 1310. The one or more sensors 1310 include, but are not limited to: acceleration sensor 1311, gyroscope sensor 1312, pressure sensor 1313, optical sensor 1314, and proximity sensor 1315.

The acceleration sensor 1311 can detect the magnitudes of accelerations on three coordinate axes of the coordinate system established with the terminal 1300. For example, the acceleration sensor 1311 may be used to detect components of gravitational acceleration in three coordinate axes. Processor 1301 may control touch display screen 1305 to display a user interface in either a landscape view or a portrait view based on gravitational acceleration signals acquired by acceleration sensor 1311. The acceleration sensor 1311 may also be used for the acquisition of motion data of a game or user.

The gyro sensor 1312 may detect a body direction and a rotation angle of the terminal 1300, and the gyro sensor 1312 may collect a 3D motion of the user on the terminal 1300 in cooperation with the acceleration sensor 1311. Processor 1301 can implement the following functions based on the data collected by gyro sensor 1312: motion sensing (e.g., changing UI according to a tilting operation by a user), image stabilization at shooting, game control, and inertial navigation.

Pressure sensor 1313 may be disposed on a side frame of terminal 1300 and/or below touch display screen 1305. When the pressure sensor 1313 is disposed at a side frame of the terminal 1300, a grip signal of the terminal 1300 by a user may be detected, and the processor 1301 performs left-right hand recognition or shortcut operation according to the grip signal collected by the pressure sensor 1313. When the pressure sensor 1313 is disposed at the lower layer of the touch display screen 1305, the processor 1301 realizes control of the operability control on the UI interface according to the pressure operation of the user on the touch display screen 1305. The operability controls include at least one of a button control, a scroll bar control, an icon control, and a menu control.

The optical sensor 1314 is used to collect ambient light intensity. In one embodiment, processor 1301 may control the display brightness of touch display screen 1305 based on the ambient light intensity collected by optical sensor 1314. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 1305 is turned up; when the ambient light intensity is low, the display brightness of the touch display screen 1305 is turned down. In another embodiment, processor 1301 may also dynamically adjust the shooting parameters of camera assembly 1306 based on the intensity of ambient light collected by optical sensor 1314.

A proximity sensor 1315, also referred to as a distance sensor, is typically provided on the front panel of the terminal 1300. The proximity sensor 1315 is used to collect the distance between the user and the front of the terminal 1300. In one embodiment, when proximity sensor 1315 detects a gradual decrease in the distance between the user and the front of terminal 1300, processor 1301 controls touch display 1305 to switch from a bright screen state to a inactive screen state; when the proximity sensor 1315 detects that the distance between the user and the front surface of the terminal 1300 gradually increases, the touch display screen 1305 is controlled by the processor 1301 to switch from the off-screen state to the on-screen state.
