In each AI paradigm, datasets were an important component. The accuracy of the related data leads to analytical growth, preparation, and progress. For this development to be helpful, the evidence obtained should be justified and labelled by experts in computer vision. This segment includes information on the artificial intelligence of early work for the identification of lung cancer [Wang et al., 2019]. One of the most serious ailments in the globe is lung cancer. Researchers are taking action in different directions to boost lung cancer. CT scans through machine learning techniques and lung nodular identification from a variety of defects. A deeper neural network with progeny [Taher et al., 2016] extracted images of information. The technique by the author here shows that the larger the nodule, the higher the risk of cancer growth. Compared to the class labels, also known as the pattern classification, the test set includes features in the linear SVM that increase the quality of the tests. It gets CT images using compressed technology ROI segmentation [Deep Prakash, et al. 2017]. Each ROI image is broken into a different DWT (Discrete View Switch) strategy and also some SVM-detectable GLCM classification bands [Gupta et al., 2020]. A method based on nodule size is also suggested below [Kim et al., 2016], which shows excellent performance compared with ROI isolation for the detection of cancer cell types. The feature extraction [Kumar et al., 2015], including the Otsu division thresholds and gray-level repeat matrix (GLCM), is defined as the physical dimension level. It identifies cancer nodules from its view of the effect of such traits. It also grades initial stages to prevent cancer. The median filter is a method of pre-treatment for filtering salt and pepper image noise through [Murillo, 2018] and it is measured in a numerical format [MyaTun et al., 2014] via arranging the value of the entire pixel round. Some intersecting processes covering the Otsu threshold subsequently.

An analysis of the above concepts indicates that its GLCM or SVM helps in improved classifications of images of lung cancer [Kim et al., 2016]. Using these images in a CAD system, the critical characteristics are just different from several other definitions since that model is based on characteristics like NC ratio, circularity, and so forth and establishes an estimation threshold for cells coinciding only with rule-based classification.

In each artificial intelligence paradigm, datasets were an important component. The accuracy of the related data leads to analytical growth, preparation, and progress. For this development to be helpful, the evidence obtained should be justified and labelled by experts in computer vision. This segment includes information on the artificial intelligence of early work for the identification of lung cancer [Rabbani et al., 2018]. The dataset contains 1018 cases from seven research centers and eight medical diagnostic firms. An XML document of CT-scan annotations is given for each case [Chen et al., 2020]. Four skilled thoracic radiologists carry out certain annotations in a two-stage process. Every radiologist classifies the results separately into three groups (“nodule $\geq 3 \mathrm{~mm}$,” “nodule $<3 \mathrm{~mm}$,” and “nodule $\geq 3 \mathrm{~mm}$ “) [Kim et al., 2018]. Then any radiologist investigates anonymously in the second step, their classification, and the classifications of other radiologists. The four radiologists separately analyze every nodule annotation. Average values above three are classed as malignant nodules and below three as benign nodules. One of four radiologists validated an overall grade of three with certain inconsistencies and their identities, and also as some nodules were omitted from its analysis. A DCM file can also be interpreted more easily through screening, and visualizing, as seen in Figure 3.3(a), by three or five radiologists, presenting a malignant or benign stage of cancer. Browsing using a Pylidctool [Loyman et al., 2020], as seen in Figure 3.3(b), shows nodules in the CT image of LIDC-IDRI-0082 as detailed: CT Slice thickness: $1.250 \mathrm{~mm}$, pixel spacing: $0.703$, no of nodule: 1, three annotations near slice 173 and annotation info (Subtlety-4, Internal structure-1, Calcification-6, Sphericity-3, Margin-4, Lobulation-2, Speculation-5, artificial intelligence Texture-5, Malignancy-5) [Wu et al., 2019].

在每个 AI 范式中,数据集都是重要的组成部分。相关数据的准确性导致分析增长、准备和进展。为了使这一发展有所帮助,所获得的证据应由计算机视觉专家证明和标记。该部分包括有关用于识别肺癌的早期工作的人工智能信息 [Wang et al., 2019]。全球最严重的疾病之一是肺癌。研究人员正朝着不同的方向采取行动来促进肺癌。CT 扫描通过机器学习技术和肺结节识别各种缺陷。具有后代的更深层次的神经网络 [Taher et al., 2016] 提取了信息图像。作者在这里的技术表明,结节越大,癌症生长的风险就越高。与类别标签(也称为模式分类)相比,测试集包含线性 SVM 中的特征,可提高测试质量。它使用压缩技术 ROI 分割获得 CT 图像 [Deep Prakash, et al. 2017]。每个 ROI 图像都被分解为不同的 DWT(离散视图切换)策略以及一些 SVM 可检测的 GLCM 分类带 [Gupta et al., 2020]。下面还提出了一种基于结节大小的方法 [Kim et al., 2016],与 ROI 隔离相比,该方法在检测癌细胞类型方面表现出优异的性能。特征提取 [Kumar et al., 2015],包括 Otsu 分割阈值和灰度重复矩阵 (GLCM),被定义为物理维度级别。它从这些特征的影响的角度来识别癌症结节。它还对初始阶段进行分级以预防癌症。中值滤波器是一种通过 [Murillo, 2018] 过滤椒盐图像噪声的预处​​理方法,它通过排列整个像素轮的值以数字格式 [MyaTun et al., 2014] 进行测量。随后的一些交叉过程覆盖了 Otsu 阈值。

对上述概念的分析表明,其 GLCM 或 SVM 有助于改进肺癌图像的分类 [Kim et al., 2016]。在 CAD 系统中使用这些图像,关键特征与其他几个定义不同,因为该模型基于 NC 比率、圆度等特征,并为仅与基于规则的分类一致的细胞建立了估计阈值。

在每个人工智能范式中,数据集都是重要的组成部分。相关数据的准确性导致分析增长、准备和进展。为了使这一发展有所帮助,所获得的证据应由计算机视觉专家证明和标记。该部分包括有关用于识别肺癌的早期工作的人工智能信息 [Rabbani et al., 2018]。该数据集包含来自 7 个研究中心和 8 家医疗诊断公司的 1018 个病例。每个案例都给出了 CT 扫描注释的 XML 文档 [Chen et al., 2020]。四位熟练的胸部放射科医师分两阶段进行某些注释。每位放射科医生将结果分别分为三组(“结节≥3 米米,” “结节<3 米米,”和“结节≥3 米米”)[Kim 等人,2018 年]。然后任何放射科医师在第二步、他们的分类以及其他放射科医师的分类中匿名调查。四位放射科医生分别分析每个结节注释。平均值高于三个被归类为恶性结节,低于三个被归类为良性结节。四位放射科医师中的一位验证了总体等级为三,具有某些不一致及其身份,并且在其分析中省略了一些结节。如图 3.3(a) 所示,三名或五名放射科医生通过筛查和可视化呈现癌症的恶性或良性阶段,也可以更容易地解释 DCM 文件。使用 Pylidctool [Loyman et al., 2020] 进行浏览,如图 3.3(b) 所示,详细显示了 LIDC-IDRI-0082 的 CT 图像中的结节:CT 切片厚度:1.250 米米,像素间距:0.703, no of nodule: 1, 切片 173 附近的三个注释和注释信息 (Subtlety-4, Internal structure-1, Calcification-6, Sphericity-3, Margin-4, Lobulation-2, Speculation-5, 人工智能 Texture-5 , Malignancy-5) [Wu et al., 2019]。

计量经济学是利用统计方法检验经济学理论的一种方法,它既不属于统计的范畴也不属于经济的范畴更像是一种经验科学。大家有专业的问题可以在my-assignmentexpert™ 这里答疑,多读一读,相关的基础性的东西,做一些统计和经济的基础知识的积累对于学习计量经济学这一门课程都是有很大帮助的。








1.1 mark on book


A. 不懂,或是生涩,或是不熟悉的部分。这点很重要,有的定义浅显,但证明方法很奇怪。我会将晦涩的定义,证明方法标出。在看书时,所有例题将答案遮住,自己做,卡住了就说明不熟悉这个例题的方法,也标出。

B. 老师课上总结或强调的部分。这个没啥好讲的,跟着老师走就对了

C. 你自己做题过程中,发现模糊的知识点

1.2 take note


1.3 understand the relation between definitions

比如特征值,特征向量,不变子空间,Jordan blocks, Jordan stadard form的一堆定义和推论,看起来很难记,但搞懂他们之间的关系就很简单了


如果您是美本或者加拿大本科的学生,那么您的教材有很大概率是Sehldon Axler的linear algebra done right这本书,这本书通俗易懂的同时做到了只有300页的厚度,以几何的观点介绍了线性代数的所有基本且重要的内容.

从目录来看,这本书从linear vector space的定义讲起,引入线性代数这一主题,第二章开始将讨论范围限制在有限维的线性空间,这样做的好处是规避
