Top 5 Kaggle Alternatives: Platforms for Data Science Competitions

Data science competitions hosted on platforms like Kaggle provide a great opportunity for aspiring data scientists to hone their skills and showcase their work. While Kaggle is undoubtedly the largest and most popular such platform, there are several other worthy alternatives that offer similar experiences. In this post, I'll be taking a detailed look at 5 such websites that serve as good alternatives to Kaggle for participating in data science competitions.

DrivenData

One of the websites closest in spirit and function to Kaggle is DrivenData. Like Kaggle, DrivenData also hosts structured data science competitions where participants analyze datasets to solve real-world problems. However, what truly sets it apart is its focus on using data science specifically for social good.

DrivenData competitions typically revolve around important societal issues like poverty, education, healthcare access etc. The datasets used are obtained from reputed non-profit organizations working in these domains. Competitions are structured in multiple stages, with participants first exploring the data, then building models and deriving insights before the final stage of communicating findings.

In terms of pricing, individual participation in DrivenData competitions is completely free. For teams and organizations wanting additional features and support, paid premium plans start at just $99 per month. The community is smaller compared to alternatives like Kaggle but it remains quite engaged and discussion-focused.

While the fewer number of concurrent competitions could be a limitation, DrivenData's social impact orientation is certainly a big positive. It's a fantastic platform for aspiring data scientists wanting to apply their skills for social good causes.

CrowdAnalyst

CrowdAnalyst takes a very similar approach to DrivenData by focusing data science projects and competitions around humanitarian issues. Many of its challenges involve analyzing datasets obtained during disaster relief efforts, with the aim of deriving insights that can help improve preparedness and response measures.

Competitions follow a structure analysis-insights-communication process very similar to DrivenData. Participation is free for individuals while pricing plans for organizations aren't explicitly mentioned. The community is relatively tight-knit but remains engaged through forums and leaderboards.

While the specialized domain could limit wider appeal, CrowdAnalyst is ideally suited for those interested in leveraging data science to address pressing humanitarian concerns. The use of real disaster response data also gives competitions higher practical relevance compared to some other platforms.

BenchSci

Shifting to a more industry-focused alternative, BenchSci caters specifically to the life sciences domain. As a platform for biomedical researchers, it allows analyzing relevant datasets and publishing findings. In addition, BenchSci also hosts data science competitions in focused fields like genomics, drug discovery and biomarkers.

Pricing includes free academic access while paid plans for industry/business start at a reasonable $99 per month. Given its life sciences niche, participant numbers are understandably smaller than general platforms. However, the dedicated community remains highly engaged through scientific collaborations and peer discussions on the platform.

With its domain expertise and curated datasets, BenchSci is ideal for data scientists passionate about leveraging their skills in biomedical research challenges. While narrow in scope, it effectively taps into an industry need that broader platforms may not address as well.

Analytics Vidhya

Originating from India, Analytics Vidhya provides one of the largest options for global participation in data science competitions. In addition to regularly hosted challenges, it also features a wealth of tutorials, course material and insights on analytics topics.

Competitions cover a wide range of problem domains utililizing techniques like machine learning, deep learning, NLP, computer vision and more. Participation is free for individuals while paid plans for enterprises aren't explicitly defined. Community forums foster lively interaction among a very sizeable participant base.

As one of the earliest players catering to South Asian audiences, Analytics Vidhya benefits from brand recognition and scale. The well-rounded content offering and active forums make it great for learning while competing. Its massive reach also enables wider networking opportunities compared to smaller focused platforms.

TopCoder

Still going strong after two decades, TopCoder is among the pioneering platforms that have helped popularize competitive programming. While its remit has expanded over the years, core challenges remain centered around coding problems and algorithm/data structure design.

TopCoder exposes participants to issues across diverse domains that can then be addressed using techniques like machine learning, computer vision etc. Competitions are open for individuals to participate freely while team/organizational plans involve fees. Scale and experience have also helped cultivate an immense talent pool over the years.

Longevity comes with some trade-offs though, as the interface feels slightly dated and complex compared to more recent entrants. Challenges also assume more of an expert coder/hardcore competitive programmer profile. But for seasoned data scientists, TopCoder remains an excellent testing ground.

Final Words

While Kaggle unquestionably leads the way given its early mover advantage and Microsoft backing, platforms discussed above have carved compelling niches of their own. Choosing the right alternative depends on individual priorities around domain focus, problem-types, participation costs and community characteristics.

All are excellent ways for data scientists to showcase and enhance skills, network with peers as well as explore varied issue domains. Competition experience gained through consistent participation also helps strengthen industry employability in the long run. So beyond Kaggle, these alternatives definitely deserve consideration too from aspiring data science enthusiasts.
