However, the stress-test reveals a more specific and more central weakness than the reader's stated concern about literature selection bias. The paper's main contribution is the proposed division of Edge Intelligence into AI for edge and AI on edge, and the road-map in Fig. 1 depends on those two branches being meaningfully separable. The paper's own examples blur that separation: federated learning via over-the-air computation appears both as an intelligent wireless networking technique (AI for edge) and as a model-training framework or adaptation (AI on edge). The text even admits this dual classification. Because the central claim is about how to organize the field, an internally inconsistent taxonomy undermines the paper's utility even if the literature sample were perfectly representative. I therefore partially agree with the reader's diagnosis: the selection-bias concern is real but secondary. A conditional verdict is appropriate: the paper's contribution can be salvaged by clarifying that the two branches are analytical perspectives rather than a disjoint partition, and by adding an explicit treatment of boundary cases such as learning-driven communication for federated training.

Yet these same mechanisms directly serve model training on the edge, which is the defining concern of AI on edge in Section III-C and Section V-A. The text explicitly concedes the overlap: after describing [39], it states that this contribution 'can also be categorized as Model Adaptation in AI on edge, but it accelerates Federated Learning from the perspective of fast data acquisition.' If a representative set of cited works satisfies both definitions, then the boundary is not a property of the work but a choice of viewpoint, and the central claim that Edge Intelligence 'should be divided into' these two directions is correspondingly weakened. A reader cannot use the road-map to classify a new paper without already knowing which side the authors intend.

The paper reviews selected state-of-the-art works in several subtopics (wireless networking, service placement and caching, computation offloading, model compression, conditional computation, algorithm asynchronization, and thorough decentralization) and discusses grand challenges in both directions.

The paper's distinction between using AI to improve edge systems and running AI models on edge systems is a natural and potentially clarifying framing. The paper also usefully collects representative recent work in both directions and highlights open challenges. However, the paper is a position/survey paper with no systematic methodology: it contains no derivation, no data, and no formal evaluation of its taxonomy. Its value rests entirely on whether the proposed categories are coherent and whether the selected examples are representative. The paper does not provide a systematic literature-selection protocol, and, more importantly, the two central categories overlap in the very examples used to illustrate them, which weakens the claim that Edge Intelligence \"should be divided into\" these two directions.","major_comments":[{"comment":"The central dichotomy between AI for edge and AI on edge is not a partition as claimed.

That split has been useful to people entering the field, and the paper is a decent road-map. But the division is not a partition, and the authors themselves concede several of their examples land on both sides.\n\nWhat it does well: it organizes a lot of recent work into a coherent structure — left side Topology/Content/Service, right side Model Adaptation/Framework Design/Processor Acceleration — and it puts a multi-criteria QoE lens (performance, cost, privacy, efficiency, reliability) on top. The writing is clear, the grand challenges are sensible, and the examples are mostly representative of the subareas. There are no derivations or data to verify; it's a synthesis, and judged as a synthesis it's competent.\n\nSoft spots: the central claim that Edge Intelligence 'should be divided into' the two directions is softer than it looks. In Section IV-A1, Learning-driven Communication — over-the-air aggregation for Federated Learning [38], [39], importance-aware retransmission [40] — is filed under AI for edge, but the same mechanisms directly serve model training on the edge, which is the core of AI on edge. The text says of [39] that it 'can also be categorized as Model Adaptation in AI on edge,' and [41] is noted as sharing concerns with Model Adaptation. So the taxonomy is really two viewpoints rather than an exclusive split. If you're trying to classify a new paper, you often can't tell which side it belongs to without knowing the authors' intent. That is a real internal-consistency issue, and I'd ask the authors to address it.\n\nThe other soft spot is selection bias: the survey says it focuses on 'hot topics' but gives no systematic protocol or inclusion criteria. That's a minor issue for a position paper, but combined with the partition problem it means the road-map is more of a curated map than a faithful representation of the field.\n\nOn circularity: the self-citations are used as illustrative examples of the proposed directions. That's normal for a survey, not a circular argument.\n\nWho it's for: newcomers to edge intelligence who want a quick map; also useful for a reading group discussion about how to slice the field. It does not need to be cited as a technical result, but it's a reasonable survey citation.\n\nRecommendation: send it to peer review. The taxonomy needs a caveat that the two branches are complementary lenses, not a partition, and the example selection should be justified. With that revision, it's a solid survey.\n\nBest.","headline":"Readable survey and position paper on Edge Intelligence whose central two-way split is a useful coarse map but not a clean partition, since the paper's own examples overlap.","tokens_in":20658,"tokens_out":3708,"would_cite":true,"duration_ms":282569,"reading_group":"yes","serious_thinker":"yes","would_accept_peer_review":true},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"This survey argues that Edge Intelligence is best organized as two research directions — AI for edge and AI on edge — joined under one quality-of-experience goal.","keywords":["Edge Intelligence","Edge Computing","Artificial Intelligence","AI for edge","AI on edge","Federated Learning","Computation Offloading","Quality of Experience"],"falsifier":"A reader could settle the matter by building a systematic corpus of edge-intelligence publications with explicit inclusion criteria and counting how many fit one of the road-map's cells: if a substantial share of papers falls outside both the AI-for-edge and AI-on-edge branches — or fits both — the claimed division would fail as an organizing framework.","tokens_in":19717,"feed_emoji":"🗺️","tokens_out":7380,"duration_ms":56769,"temperature":0.7,"pith_summary":"Edge Intelligence — the integration of Edge Computing and Artificial Intelligence — has no formal definition, and the survey literature has grown piecemeal.

On one side, AI for edge (Intelligence-enabled Edge Computing) treats AI as an optimization tool: deep neural networks, deep Q-networks, multi-armed bandits, and reinforcement learning supply near-optimal solutions to edge-computing problems in topology (edge-site orchestration, wireless networking), content (data and service provisioning, placement, composition, caching), and service (computation offloading, user-profile migration, mobility management). On the other side, AI on edge (Artificial Intelligence on Edge) asks how the full model lifecycle — training and inference — can run on devices and edge servers with device-edge-cloud synergy, organized top-down into model adaptation (compression, conditional computation, asynchronization, decentralization), framework design (federated learning, knowledge distillation, model splitting), and processor acceleration. Both branches pursue the same top-level objective, Quality of Experience, defined by performance, cost, privacy (security), efficiency, and reliability.
