提高机器学习模型准确性的方法和技巧

无论是普通英语还是专门用途英语翻译，首要标准都应该是“准确”，即“诚实、达意”。尤其是翻译处于基础层级的非艺术性文本—商务公函、合同、协议、产品说明、备忘录、会议纪要等一般商务文书时，应注重其纪实性，恪守“诚信”的根本原则，准确把握原语的意义，一字不误、一丝不苟地如实转换。

According to the horizontal analysis on the financial situation about ABC Company from 2007-201l which indicates that the sales of ABC Company continue to grow during the last five years with an average increase rate of 42.68%.The super increase rate owes to the wide spread of modern internet；it also certainly proves the successful management mode and stralepic policy executed by ABC Company，

Based on the vertical analysis on the financial situation，the profit ratio in 2010 is reasonable.The profit statement structure changed obviously in 201l compared with 2010.The revenues decreased a little and other income decreased by 3.6%，while the cost of sales increased by 4.5% and the total operating expense increased by 7.4%.There’s another obvious change that the total income before tax in 201l increased by more than 3 times to 425 thousand Yuan compared with 2010.The total income before tax is revenues plus or minus other incomes and incomes from investment，so we can deduce that ABC Company won excess investment returns from its investments.译文：根据ABC公司年财务状况的水平分析，ABC公司销售收入五年间持续增长，每年平均增长42.68%，这种超级增长率的形成与当今社会的网络普及化密不可分，当然这也是公司的管理模式和战略决策方面的成功表现。

基于对该公司财务状况的纵向分析，2010年利润比例比较合理，2011年的利润表结构与2010年相比有明显的结构性变化，收入略有下降的情况下，销售成本上升了4.5个百分比，费用上升了7.4个百分比。其他收入下降了3.6个百分比。(www.xing528.com)

更明显的变化是税前利润总额2011年比2010年绝对值增加了约425，000元，增加了约3倍多。税前利润总额是在营业利润的基础上加减其他收入及投资收益而来，由此可以推出ABC公司2011年获得了超额的投资收益回报。除了财务报告之外，各类商务策划书的翻译也应首先遵循“准确性”原则，以下为某品牌葡萄酒营销策划书节选：Marketing status at present（1）Market status：The wine is the second largest popular beverage wine and second-lowest only to beer in the international drink market，but in our country，it is just only a small wine at present，the annual production has been wandering up and down about 200，000 tons all the time for many years，even less than 1% of the national total amount of alcohol product.Consumption per capita wine of our country is only 1/20 of the level of consumption on average in recent times.At present，with the improvement of people’s living standard and health consciousness，the change of the diet idea，and various propaganda of the wine，making the wine market of our country develop quickly，especially the claret is a focus of present consumption.Look from this angle，the potential market of the wine of our country is very broad.（2）Product status：Domestic：The market price of wine in China has been on the rise all the time since 1996，especially the price of the claret is very large in ascensional range，prices different depends on the brands，each bottle（750ml）rises from 25 Yuan to 40-60 Yuan， the price of wine of other kinds has rising in various degree too.Overseas：the quality of domestic wine is better than that of overseas，and the price is also reduced gradually with the decrease of the tariff too，and with the sale channel expanded and wine knowledge increased，more and more foreign products therefore be adopted by Chinese consumers，as a result，foreign wine enters the domestic market now is more easily than the past.（3）Competition status：The competition is relatively stable.At present，domestic Zhang Yu，Great Wall，Dynasty，these three major brands occupy half of domestic market，52% or so.Dozens of foreign brands from such as France，Italy，and other else countries take the rest part of the market.Most of domestic brands only focus their eyes on a certain region and sell their product to limited places，they are lack of marketing competition and without enough ability to enter in the international market.In virtue of tariff decreasing and barrier of foreign wines entering China releasing.Thus makes the competition of their brands further promoted.

译文：目前营销状况（1）市场状况：葡萄酒是国际酒类市场中仅次于啤酒的第二大流行饮料酒，但在我国，目前还是一个小酒种，年产量多年来一直在20万吨左右徘徊，还不到全国酒类产品总量的1%。我国葡萄酒的人均消费量仅占当前世界平均消费水平的1/20。近年来，随着人们生活水平和健康意识的提高，饮食观念的变化，加上各种媒体对葡萄酒的宣传，使我国葡萄酒市场发展很快，尤其是干红葡萄酒更是当前消费的热点。从这个角度看，我国葡萄酒的潜在市场十分广阔。（2）产品状况：国内我国葡萄酒市场价格从1996年以来一直是呈上升趋势，特别是干红葡萄酒的价格上升幅度很大，依品牌不同，每瓶（750毫升）从25元上升至40-60元不等，其他种类葡萄酒的价格也有不同程度的上升。国外：国内的葡萄酒质量一般较国外的好，价格也随着关税的降低在逐渐降低，再加上销售渠道的扩展和消费者逐渐增加葡萄酒知识，国外的产品将被消费者接受，所以现在洋葡萄酒进入国内市场要比过去容易。（3）竞争状况：竞争格局相对稳定。目前国内张裕、长城、王朝三大品牌平分秋色，占据了国内约52%的市场，再加上十几个分别是来自于法国、意大利等国的进口品牌。大多数国产品牌只能囿于某一地区争夺立足之地，缺乏市场竞争力，更没有角逐国际市场的能力。而由于国内对葡萄酒类产品进口关税的降低，国外葡萄酒进入中国的壁垒降低，从而使得其品牌的竞争力得到进一步提升。
