在金融行业中,对信用风险的判断是核心环节之一,其结果对机构的信贷政策和风险控制策略有直接影响。本文将围绕如何借助机器学习方法,尤其是Sklearn工具包,建立用于判断信用状况的预测系统。文中将涵盖逻辑回归、支持向量机等常见方法,并通过实际操作流程进行说明。 一、机器学习基本概念 机器学习属于人工智能的子领域,其基本理念是通过数据自动学习规律,而非依赖人工设定规则。在信贷分析中,该技术可用于挖掘历史数据中的潜在规律,进而对未来的信用表现进行预测。 二、Sklearn工具包概述 Sklearn(Scikit-learn)是Python语言中广泛使用的机器学习模块,提供多种数据处理和建模功能。它简化了数据清洗、特征提取、模型构建、验证与优化等流程,是数据科学项目中的常用工具。 三、逻辑回归模型 逻辑回归是一种常用于分类任务的线性模型,特别适用于二类问题。在信用评估中,该模型可用于判断借款人是否可能违约。其通过逻辑函数将输出映射为0到1之间的概率值,从而表示违约的可能性。 四、支持向量机模型 支持向量机是一种用于监督学习的算法,适用于数据维度高、样本量小的情况。在信用分析中,该方法能够通过寻找最佳分割面,区分违约与非违约客户。通过选用不同核函数,可应对复杂的非线性关系,提升预测精度。 五、数据预处理步骤 在建模前,需对原始数据进行清理与转换,包括处理缺失值、识别异常点、标准化数值、筛选有效特征等。对于信用评分,常见的输入变量包括收入水平、负债比例、信用历史记录、职业稳定性等。预处理有助于减少噪声干扰,增强模型的适应性。 六、模型构建与验证 借助Sklearn,可以将数据集划分为训练集和测试集,并通过交叉验证调整参数以提升模型性能。常用评估指标包括准确率、召回率、F1值以及AUC-ROC曲线。在处理不平衡数据时,更应关注模型的召回率与特异性。 七、集成学习方法 为提升模型预测能力,可采用集成策略,如结合多个模型的预测结果。这有助于降低单一模型的偏差与方差,增强整体预测的稳定性与准确性。 综上,基于机器学习的信用评估系统可通过Sklearn中的多种算法,结合合理的数据处理与模型优化,实现对借款人信用状况的精准判断。在实际应用中,需持续调整模型以适应市场变化,保障预测结果的长期有效性。 资源来源于网络分享,仅用于学习交流使用,请勿用于商业,如有侵权请联系我删除!

UsbFfs-monitor thread spawned再结合androidlog分析为啥adb断连
07-13
<think>我们分析日志以确定ADB断连的原因。结合提供的日志,我们重点关注与ADB相关的部分,同时考虑温度、权限和USB配置等问题。 ### 关键日志分析 1. **ADB连接尝试与失败**: - `adbd` 尝试通过 `UsbFfsConnection` 建立连接: ``` 01-01 13:59:17.057 01859 01871 I adbd : UsbFfsConnection constructed 01-01 13:59:17.061 01859 13941 I adbd : UsbFfs-monitor thread spawned ``` - 但随后出现超时错误: ``` 01-01 13:59:18.065 01859 13941 W adbd : timed out while waiting for FUNCTIONFS_BIND, trying again 01-01 13:59:18.066 01859 13941 I adbd : UsbFfs: connection terminated: monitor thread finished 01-01 13:59:18.069 01859 01859 I adbd : UsbFfs: already offline 01-01 13:59:18.069 01859 01859 I adbd : destroying transport UsbFfs ``` - 同样的情况在稍后重复发生: ``` 01-01 13:59:19.125 01859 13942 W adbd : timed out while waiting for FUNCTIONFS_BIND, trying again 01-01 13:59:19.126 01859 13942 I adbd : UsbFfs: connection terminated: monitor thread finished ``` 2. **高温问题**: - 温度传感器(TZ:15)报告的温度持续在60°C左右(如61000表示61.000°C): ``` 01-01 13:59:17.059 01437 01473 I android.hardware.thermal@2.0-service.qti-v2: thermal_sample_event: TZ:15 temp:61000 ``` - 高温可能触发系统保护机制,导致USB功能异常。 3. **USB配置失败**: - 在之前的kernellog中,我们看到USB配置失败: ``` init: Command 'write /config/usb_gadget/g1/UDC ${sys.usb.controller}' ... failed: Unable to write ... No such device ``` - 当前日志中,`adbd` 尝试打开控制端点时可能因此失败: ``` 01-01 13:59:18.103 01859 01871 I adbd : opening control endpoint /dev/usb-ffs/adb/ep0 ``` 4. **SELinux权限问题**: - 尽管不是直接原因,但之前有SELinux拒绝访问 `devfreq` 目录的日志,可能影响系统稳定性: ``` 01-01 13:59:17.803 01958 01958 W traced_probes: type=1400 audit(0.0:8771): avc: denied { read } for name="devfreq" ... ``` ### 断连原因推断 1. **高温保护**: - 电池温度持续在58.5°C以上(见之前日志),而CPU/SoC温度(TZ:15)达到60°C以上,可能触发系统降频或关闭非核心外设(如USB控制器)。 2. **USB配置失败**: - 内核初始化USB时反复失败(`UDC core: couldn't find an available UDC or it's busy: -19`),导致ADB无法绑定到USB FunctionFS。 3. **ADB连接超时**: - `adbd` 在等待 `FUNCTIONFS_BIND` 时超时,表明USB主机端未正确响应或设备端USB栈异常。 ### 解决方案建议 1. **降温设备**: - 暂停高负载任务,移除保护壳,避免充电(因充电会加剧发热)。 2. **检查USB硬件**: - 更换USB线或端口,排除物理连接问题。 3. **重启ADB服务**: - 在设备端重启 `adbd`: ```bash adb kill-server && adb start-server # 在主机端 setprop ctl.restart adbd # 在设备端(需root) ``` 4. **临时禁用SELinux**(测试用): ```bash adb shell setenforce 0 ``` 5. **更新固件/驱动**: - 联系设备厂商获取针对高温和USB问题的固件更新。 §§相关问题§§ 1. 如何实时监控Android设备的CPU和电池温度? 2. 高温保护机制触发时系统会限制哪些功能? 3. 如何诊断USB FunctionFS绑定失败的具体原因? 4. 除了ADB,高温是否会影响其他USB功能(如MTP)? 5. 如何永久修复SELinux策略导致的`traced_probes`权限问题?</think>### ADB断连原因分析 结合提供的Android日志和之前的分析,ADB断连的主要原因是**高温触发的USB控制器故障**和**USB配置失败**。以下是关键证据和详细解释: #### 1. **高温导致USB控制器异常** - **温度持续超标**: - 电池温度:稳定在58.5°C(`bat_temp=585`),超过53°C的警戒线 - SoC温度(TZ:15):反复达到61°C(`temp:61000`),触发高温保护 ``` 01-01 13:59:17.059 I android.hardware.thermal: thermal_sample_event: TZ:15 temp:61000 01-01 13:59:17.251 E OPLUS_CHG: bat_temp(585) > 53'C ``` - **高温影响**: - 高温导致USB控制器(UDC)无法正常工作: ``` 01-01 13:59:11.976 W UDC core: couldn't find an available UDC or it's busy: -19 ``` - 错误码`-19`表示设备不存在或资源被锁定,通常由过热引起 #### 2. **USB配置反复失败** - **ADB初始化关键错误**: - USB Gadget配置失败(符号链接已存在但无法激活): ``` 01-01 13:59:11.973 I init: symlink() failed: File exists 01-01 13:59:11.977 I init: Unable to write to file '/config/usb_gadget/g1/UDC': No such device ``` - ADB守护进程(adbd)尝试重置连接但超时: ``` 01-01 13:59:18.065 W adbd: timed out while waiting for FUNCTIONFS_BIND 01-01 13:59:19.125 W adbd: timed out while waiting for FUNCTIONFS_BIND ``` #### 3. **其他关联问题** - **电池管理异常**: - 电量计量错误(`UI_SOC = 103 larger 100`)可能与高温相关 - **系统负载过高**: - 日志服务频繁记录高温事件(每秒2-3次),消耗系统资源 - **通知系统异常**: - UI组件高度值异常(`height = 1073741823`),表明系统状态不稳定 ### 根本原因总结 1. **高温触发保护机制**:持续61°C的SoC温度导致USB控制器被强制降频或关闭。 2. **USB栈初始化失败**:高温下无法正确挂载ADB的FunctionFS驱动。 3. **连锁反应**:adbd进程因USB资源不可用而超时断开。 ### 解决建议 1. **立即降温**: - 停止充电,移除手机保护壳 - 使用冷却风扇或置于空调出风口 2. **硬件检查**: - 检测电池健康状况(是否膨胀) - 检查USB端口是否氧化或损坏 3. **软件修复**: ```bash # 重启USB控制器(需root) echo 0 > /sys/bus/usb/devices/usb1/authorized echo 1 > /sys/bus/usb/devices/usb1/authorized # 强制重启adbd setprop ctl.restart adbd ``` 4. **长期预防**: - 更新Thermal HAL驱动 - 优化系统后台服务(减少日志记录频率)
