The user perception of mobile game is crucial for improving experience and thus enhancing profitability. sparse data captured in the can lead to sporadic performance model. This paper proposes a new method, balanced graph factorization machine (BGFM), based on existing algorithms, considering imbalance important high-dimensional features. categories are first by Borderline-SMOTE oversampling, then features represented naturally graph-structured way. highlight that BGFM contains interaction mechanisms aggregating beneficial results as edges graph. Next, combines (FM) neural network strategies concatenate any sequential feature interactions with an attention mechanism assigns inter-feature weights. Experiments were conducted collected dataset. proposed was compared eight state-of-the-art models, significantly surpassing all them AUC, precision, recall, F-measure indices.

Synthetic aperture radar (SAR) change detection provides a powerful tool for continuous, reliable, and objective observation of the Earth, supporting wide range applications that require regular monitoring assessment changes in natural built environment. In this paper, we introduce novel SAR image method based on principal component analysis two-level clustering. First, two difference images log-ratio mean-ratio operators are computed, then fusion model is used to fuse images, new generated. To incorporate contextual information during feature extraction phase, Gabor wavelets obtain representation across multiple scales orientations. The maximum magnitude all orientations at each scale concatenated form vector. Following this, cascading clustering algorithm developed within discriminative space by merging first-level fuzzy c-means with second-level neighbor rule. Ultimately, combination changed unchanged results produces final map. Five datasets experiment, show our has significant advantages detection.

Sparse has achieved significant effectiveness fusion, it used to process low-frequency band; excellent edge-preserving effects effectively maintain spatial continuity band. Therefore, combined with weighted sum eight-neighborhood-based modified (WSEML) bands. Finally, inverse LP transform reconstruct fused image. We conducted simulation experiments publicly available TNO dataset validate superiority our proposed algorithm fusing images. Our preserves both thermal radiation characteristics detailed features
