Deleuze is usually regarded as the representative philosopher and aesthete of western post-structuralism. His tuber theory has some basic characteristics, such as the principle of connection, heterogeneity, pluralism, anti-meaning division, drawing and applique. (16) has theoretical significance in thinking about the image age triggered by electronic media and explaining the visual culture and art of cyberspace, and can be used as a theoretical schema to understand contemporary digital culture and art.

The first and second characteristics of tuber express "the principle of connection and heterogeneity". Tubers are very different from those trees that are fixed in order based on only one point. The root type includes lineage or centralism, and the tuber type removes the center and puts it into other dimensions. The core of these two characteristics is "multiple heterogeneous links", and the characteristics of electronic media are quite consistent with these characteristics of tuber. Deleuze's media thoughts, including his film philosophy and aesthetic thoughts, sublated the framework of Saussure's linguistics and western structuralism, and absorbed more nutrition from the pluralistic symbolism represented by American philosopher Pierce. Pierce's semiotics transcends language and attaches importance to the diversity of images. On the other hand, the tuber theory holds that language-centered literary texts should be associated with video and audio, and should be associated with various code patterns (biology, politics, economy, etc.). Tubers continue to establish links between symbol chain, power structure (which is obviously related to Foucault's concept of "discourse power") and environment related to art, science and social struggle (. The cyberspace of electronic media is such a contemporary situation with "multiple heterogeneous links" and complex power relations.

The third characteristic of tuber is "diversity principle". The diversity of tubers no longer exists as the subject or object related to "one", natural reality or spiritual reality, and the relationship between images and the world. Multivariate tuber schema is different from pseudo-pluralism of tree model and cluster root model. It is neither subject nor object, only determination, size, movement and dimension. The expansion of tuber connection will inevitably bring about changes in its properties. The essence of "diversity principle" is the ideological tradition of opposing the tree-like binary opposition principle. A fundamental difference between Deleuze's tuber theory and Plato's cave myth is that he advocates the multi-generation principle of tuber and never abandons the theoretical schema of real/virtual binary opposition. Deleuze believes that western traditional thoughts tend to attach importance to reality and ignore simulacra (or copy, simulacra) and generated virtual force (meaning potential or unfinished state). Virtual power is a powerful force that urgently needs to be generated. It is not based on a certain purpose or something that already exists (truth or reality). Virtual has rich differences, and it innovates in an unpredictable way. From this perspective, the uniqueness of literary and artistic works lies not in describing what the world is, but in transforming the world through artistic images that are both true and illusory. Only when the potential of virtual reality is brought into play can we realize it. The strength of literature and art lies in that it is different from reality, transcending the stagnant life, producing new simulacra and new life expression. In a word, Deleuze thinks that the relationship between virtual and reality is dynamic and full of opportunities.

The fourth characteristic of "tuber" is "the principle of opposing fission". Tuber can be broken and spread, but it can still grow and reproduce in the old and new environment. People can never get rid of ants, because ants constitute the tubers of animals. Even if most ants are devastated, they can reunite again and again. The organization layers and shapes everything and returns power to the signifier. Tubers are anti-genealogical. (18) is characterized by anti-bureaucratization, de-localization, anti-organization, anti-fixed meaning and anti-genealogy, which is spiritually interlinked with the aforementioned smooth space and nomadic aesthetics. Tuber computer network is a good example to explain the anti-fission principle. Electronic media can be easily copied, edited and digitally synthesized for various purposes, including cybercrime and the creation of new multimedia literary forms. Its meaning is endless and its form is changing rapidly. The continuation, rewriting, backward writing, parody and even spoofing of literary classics have become commonplace in the electronic network world. Network writers and audiences have infinite possibilities of multiple interactions. The network world is dynamically intertwined with smooth space and stripe space.

The fifth and sixth characteristics of tuber are "Comania principle of drawing and applique". This feature distinguishes the thoughts of Deleuze and Cathary from any thoughts about the axis of occurrence and deep structure. Deleuze provided a schema generated by heterogeneous things and a multivariate rheological collage model with post-structuralism significance, which was mainly expounded through the speculation of tuber schema and tree model. Their famous example is the mutual tuber schema of orchids and bees (animals and plants): they are heterogeneous factors, but they constitute a tuber schema. Bees pollinate orchids when collecting honey, and both sides continue the life chain of survival and reproduction. Tuber schema is different from always trying to return to the same tree, so it is impossible to trace the pedigree track of bees in orchid life. The tuber schema is open and can be associated with many dimensions (orchids can be associated with bees, butterflies and even other small insects, and they also form a schema). Similarly, long-term memory or organized memory (family, race, society and civilization) is tree-like and centralized, which inspires a sad ideological image that imitates hierarchy and subjectivity. Short-term memory is a kind of tuber or geometric schema, which is not governed by the law of continuity. It can appear or return after a long distance and a long time, and has the characteristics of discontinuity, discontinuity, diversity and creativity (Proust's famous "involuntary memory" in Memories of Time Past is this kind of memory, which makes Tilia Jasmine Tea, madeleine dessert and the narrator's vivid memories of Sodom come into being.

The above-mentioned multiple speculations about tuber schema and tree model highlight the basic characteristics of Deleuze's philosophy of difference and enlighten us to think about cyberspace and digital electronic media from a philosophical perspective.
